Same day discharge after interventional electrophysiology procedures, first German experience

Abstract Background and purpose In most European countries, the current postprocedural gold standard following electrophysiological (EP) interventions implies the overnight monitoring of the patients in the hospital. Due to limited healthcare capacities and an increasing safety profile of ablation procedures, the mandatory overnight monitoring is under debate. Same day discharge protocol (SDD) ablation might be a safe and efficient alternative. We present the first German experience on SDD for EP interventions. Methods Patients receiving interventional EP procedures with a maximum of two VAs were discharged on the day of procedure, after the hemostasis and ambulation were proven. The VA hemostasis was achieved either by using a vascular closure system (VCS) or by a figure-of-eight suture followed by compressive bandage application. All patients were scheduled for a medical visit the day after procedure for groin examination and suture removal. Results A total of 12 patients (25% females, median age 64 (57.3, 66.8) years, median BMI 30.5 (22.3, 33.7) Kg/m2) undergoing EP procedures followed the SDD protocol in our center. All patients had an atrial fibrillation (AF) diagnosis, 66.7% of them paroxysmal. Five (45.5%) patients had a CHA2DS2VASc score of 1. A total of 4 (33.3%) patients presented arterial hypertension, 3 (25%) diabetes mellitus, 1 a history of stroke, 1 of myocardial infarction and 1 had chronic kidney disease and kidney transplantation. Eleven (91.7%) patients were under oral anticoagulation. The most common procedure was AF ablation, in 10 (83.3%) patients, while 1 (8.3%) patient underwent cavotricuspid isthmus (CTI) ablation and 1 (8.3%) a left atrial appendage closure procedure. In 10 (72.7%) AF ablations the energy source was cryoenergy, in 1 laserenergy and in 1 electroporation. The CTI ablation was performed by means of radiofrequency. A VCS was used in 7 (58.3%) patients. Six of these patients received 2 VCSs, while the patient with PFA based ablation had a single vascular access, thus only one VCS. The procedure was reported successful in all cases, and no intraprocedural complication occurred. During the next day visit, a groin hematoma has reported in 2 (16.7%) patients, no one requiring further therapeutical measures or hospitalization. All the other patients had no puncture related complications. The median FU time was 46.5 (26, 90.3) days. During FU only one patient had an unplanned ambulatory visit due to flecainide intolerance. Readmission during FU was reported in only 2 patients, none of them procedure related. Conclusions In selected patients undergoing EP procedures SDD seems to be safe and feasible. This approach increases healthcare capabilities, patients' comfort and reduces the cost of medical care.

Practical guidance to reduce radiation exposure in electrophysiology applying ultra low-dose protocols: a European Heart Rhythm Association review.

Interventional electrophysiology offers a great variety of treatment options to patients suffering from symptomatic cardiac arrhythmia. Catheter ablation of supraventricular and ventricular tachycardia has globally evolved a cornerstone in modern arrhythmia management. Complex interventional electrophysiological procedures engaging multiple ablation tools have been developed over the past decades. Fluoroscopy enabled interventional electrophysiologist throughout the years to gain profound knowledge on intracardiac anatomy and catheter movement inside the cardiac cavities and hence develop specific ablation approaches. However, the application of X-ray technologies imposes serious health risks to patients and operators. To reduce the use of fluoroscopy during interventional electrophysiological procedures to the possibly lowest degree and to establish an optimal protection of patients and operators in cases of fluoroscopy is the main goal of modern radiation management. The present manuscript gives an overview of possible strategies of fluoroscopy reduction and specific radiation protection strategies.

Cardiac tamponades related to interventional electrophysiology procedures are associated with higher risk of short-term hospitalization for pericarditis but favourable long-term outcome.

To investigate the association of iatrogenic cardiac tamponades as a complication of invasive electrophysiology procedures (EPs) and mortality as well as serious cardiovascular events in a nationwide patient cohort during long-term follow-up. From the Swedish Catheter Ablation Registry between 2005 and 2019, a total of 58 770 invasive EPs in 44 497 patients were analysed. From this, all patients with periprocedural cardiac tamponades related to invasive EPs were identified (n = 200; tamponade group) and matched (1:2 ratio) to a control group (n = 400). Over a follow-up of 5 years, the composite primary endpoint-death from any cause, acute myocardial infarction, transitory ischaemic attack (TIA)/stroke, and hospitalization for heart failure-revealed no statistically significant association with cardiac tamponade [hazard ratio (HR) 1.22 (95% CI, 0.79-1.88)]. All single components of the primary endpoint as well as cardiovascular death revealed no statistically significant association with cardiac tamponade. Cardiac tamponade was associated with a significantly higher risk with hospitalization for pericarditis [HR 20.67 (95% CI, 6.32-67.60)]. In this nationwide cohort of patients undergoing invasive EPs, iatrogenic cardiac tamponade was associated with an increased risk of hospitalization for pericarditis during the first months after the index procedure. In the long-term, however, cardiac tamponade revealed no significant association with mortality or other serious cardiovascular events.

Electrophysiology and arrhythmia care in Romania.

Interventional electrophysiological procedures such as catheter ablation and cardiac implantable electronic device (CIED) implantation have become important treatment options for patients with arrhythmia, but delivering state-of-the-art care can be challenging in developing countries. Romania has 19 million people. Throughout Romania, there are 28 centers that can implant CIEDs and 16 centers that can perform catheter ablation, but they are concentrated in the capital of Bucharest. Interventional arrhythmia procedures are performed less frequently than in other European countries (pacemaker: 301/million; implantable cardioverter-defibrillator: 44/million; cardiac resynchronization therapy: 13/million; catheter ablation: 0.8/million). Cardiologists with expertise in arrhythmia care have increased over the past decade and have formed an active organization that has instituted a national registry for interventional arrhythmia procedures and have been active in research and international arrhythmia organizations. Although significant work remains, our electrophysiology community is energized and is working to develop access to the best arrhythmia care for all Romanians.

Bacteria and the growing threat of multidrug resistance for invasive cardiac interventions.

Invasive cardiovascular procedures which include heart transplantations, congenital heart surgery, coronary artery bypass grafts, cardiac valve repair and replacement, and interventional cardiac electrophysiology procedures represent common mechanisms to treat a variety of cardiovascular diseases across the globe. The majority of these invasive approaches employ antibiotics as a regular and obligatory feature of the invasive procedure. Although the growing incidence of bacterial resistance to currently used antibiotics threatens to curtail the use of all interventional surgical techniques, it remains an underappreciated threat within the arsenal of cardiovascular therapies. It is reasonable to expect that the continued overuse of antibiotics and the frequent management of coronavirus disease 2019 (COVID-19) infected patients with high doses of antibiotics will inevitably accentuate the rise of multidrug resistance. The purpose of this article is to heighten awareness of the role of bacterial infections in cardiovascular disease, the use of antibiotics in today's cardiovascular surgical theaters, the threat facing cardiovascular surgery should multidrug resistance continue to rise unabated, and the development of new antibiotic platforms to solve this problem.

The Practice of Deep Sedation in Electrophysiology and Cardiac Pacing Laboratories: Results of an Italian Survey Promoted by the AIAC (Italian Association of Arrhythmology and Cardiac Pacing).

The aim of this survey, which was open to all Italian cardiologists involved in arrhythmia, was to assess common practice regarding sedation and analgesia in interventional electrophysiology procedures in Italy. The survey consisted of 28 questions regarding the approach to sedation used for elective direct-current cardioversion (DCC), subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation, atrial fibrillation (AF) ablation, ventricular tachycardia (VT) ablation, and transvenous lead extraction procedures. A total of 105 cardiologists from 92 Italian centres took part in the survey. The rate of centres where DCC, S-ICD implantation, AF ablation, VT ablation and lead extraction procedures were performed without anaesthesiologic assistance was 60.9%, 23.6%, 51.2%, 37.3%, and 66.7%, respectively. When these procedures were performed without anaesthesiologic assistance, the drugs (in addition to local anaesthetics) commonly administered were benzodiazepines (from 64.3% to 79.6%), opioids (from 74.4% to 88.1%), and general anaesthetics (from 7.1% to 30.4%). Twenty-three (21.9%) of the 105 cardiologists declared that they routinely administered propofol, without the supervision of an anaesthesiologist, in at least one of the above-mentioned procedures. In current Italian clinical practice, there is a lack of uniformity in the sedation/analgesia approach used in interventional electrophysiology procedures.

Use of a novel 4D intracardiac echocardiography catheter to guide interventional electrophysiology procedures

Standard two-dimensional (2D), phased-array intracardiac echocardiography (ICE) is routinely used to guide interventional electrophysiology (EP) procedures. A novel four-dimensional (4D) ICE catheter (VeriSight Pro, Philips) can obtain 2D and three-dimensional (3D) volumetric images and cine-videos in real-time (4D). The purpose of this study was to determine the early feasibility and safety of this 4D ICE catheter during EP procedures. The 4D ICE catheter was placed from the femoral vein in ten patients into various cardiac chambers to guide EP procedures requiring transseptal catheterization, including ablation for atrial fibrillation and left atrial appendage closure. 2D- and 3D-ICE images were acquired in real-time by the electrophysiologist. A dedicated imaging expert performed digital steering to optimize and postprocess 4D images. Eight patients underwent pulmonary vein isolation (cryoballoon in seven patients, pulsed field ablation in one, additional radiofrequency left atrial ablation in one). Two patients underwent left atrial appendage closure. High quality images of cardiac structures, transseptal catheterization equipment, guide sheaths, ablation tools, and closure devices were acquired with the ICE catheter tip positioned in the right atrium, left atrium, pulmonary vein, coronary sinus, right ventricle, and pulmonary artery. There were no complications. This is the first experience of a novel deflectable 4D ICE catheter used to guide EP procedures. 4D ICE imaging is safe and allows for acquisition of high-quality 2D and 3D images in real-time. Further use of 4D ICE will be needed to determine its added value for each EP procedure type.

Hypnotic Communication in Interventional Electrophysiology Procedures in the COVID-19 Period

Background: Hypnotic communication is a validated technique for reducing procedural anxiety and pain. The aim of our work was to evaluate the additional utility of hypnotic communication during catheter ablation procedures in the COVID-19 period. Materials and Methods: Sixteen consecutive patients undergoing electrophysiological study and catheter ablation underwent: 8 to standard sedation procedure (Group B) and 8 to this with the addition of hypnotic communication (Group A). In these two groups, we measured and compared preprocedure and intraprocedure anxiety, compliance to the procedure, perceived pain, use of drugs, the procedural time perceived by the patient compared to real time in minutes, and radiological exposure, using validated scales. Results: Hypnotic communication resulted in a significant reduction in anxiety during the procedure (Group A: 1.1 ± 0.6 vs. Group B: 3.4 ± 2; P = 0.003); better procedural compliance (Group A: 4.8 ± 0.5 vs. Group B: 3.7 ± 0.8; P = 0.002) and showed a trend toward a reduction in procedural pain (Group A: 2.4 ± 2 vs. Group B: 4.3 ± 1.8; P = 0.08) compared to standard sedation. Midazolam was not used in Group A, while an average of 3 ± 1.3 mg was used in Group B. The use of local anesthetic and Fentanest was comparable. The real procedural durations (Group A: 167.5 ± 30.1 vs. Group B: 150 ± 27.8 min; P = not significant) and perceived (Group A: 78.8 ± 15.5 vs. Group B: 86.3 ± 29.9 min; P = not significant) and the difference between these was also comparable. The radiological exposure was 74.4 ± 65.5 s in Group A and 118 ± 119 s in Group B (P = not significant). There were no complications in the two groups. Conclusions: Hypnotic communication as an additional strategy during electrophysiological interventional procedures has made possible to eliminate the use of midazolam and reduce anxiety during the procedure, but above all, it has improved the patient's compliance with the procedure compared to traditional sedation approach.

Cardiac electrophysiology and pacing educational and training needs among early-career cardiologists: a national survey of the Young Committee of the Italian Association of Arrhythmology and Cardiac Pacing.

Over the past three decades, cardiac electrophysiology and pacing, including device therapy and catheter ablation of arrhythmias, has rapidly developed as a subspecialty in cardiology. Currently, there is no clear perception about the needs in cardiac electrophysiology and pacing among early-career cardiologists. To address these concerns, the Young Committee of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) carried out a survey among those under the age of 40 years to obtain detailed information on practical activities and formal lessons during the fellowship in cardiology and their satisfaction and proficiency level at the end of the fellowship. We obtained 334 answers to the survey. In invasive cardiac electrophysiology and pacing, the percentage of participants attending the activity for a longer time (3-6 months) is lower compared with those in noninvasive subspecialties. About 40% of participants did not receive lessons on interventional cardiology, cardiac electrophysiology and pacing. On the contrary, 71% of participants received an adequate number of lessons on clinical arrhythmology. The vast majority of the participants expressed satisfaction for the education received in the echocardiographic, cardiac interventional laboratories and clinical arrhythmology, but about half of the participants were unsatisfied with the education received in cardiac electrophysiology and pacing. In interventional arrhythmology, the majority of the participants declare their lack of proficiency with two peaks for more complex procedures, namely interventional electrophysiology procedures (82%) and cardiac resynchronization therapy (CRT) procedures (76%). The present survey among Italian early-career cardiologists suggests that the majority of participants consider themselves not confident in performing cardiac electrophysiology and pacing procedures. Due to the complexity of the treatment for heart rhythm disorders and the long learning curve, structured additional training in cardiac electrophysiology and pacing procedures is required after cardiology fellowship.

Cardiac troponin release following left bundle branch pacing.

Left bundle branch pacing (LBBP) has emerged as an alternative to His bundle pacing (HBP) to achieve physiologic ventricular stimulation. The extent of myocardial injury during permanent LBBP implantation is currently not known. The aim of the study was to prospectively assess the extent of myocardial injury during LBBP implantation. Cardiac troponin (cTn) levels were measured at baseline and 6-12 h following permanent LBBP. The number of attempts to achieve LBBP was documented. Troponin levels were measured in a control population undergoing other electrophysiology procedures including HBP, other devices involving right ventricular (RV) pacing, radiofrequency ablation for atrial fibrillation (AF) and supraventricular tachycardia (SVT). Significant elevation of troponin (SET) was defined as threefold increase above the upper reference limit (URL) for cTn. Between December 2019 and April 2020, 204 were prospectively enrolled: LBBP in 98 and Control group 106 (SVT, 55; AF, 20; HBP, 17; other devices, 14). SET (>3× URL) was seen in 49.4% of patients in the LBBP group compared to 58.4% in the control group (p = .23). Peak troponin levels were greater in the control group compared to the LBBP group (230.3 ± 320.1 vs. 87.4 ± 71.3 pg/ml; p = .0001). Compared to LBBP (49.4%), SET was observed less frequently following HBP (17.5%; p = .01), and other device implantation (29%; p = .15). Patients requiring >2 attempts (n = 33) had significantly higher incidence of SET compared to <2 attempts (n = 56; 66.7% vs. 39.3%; p = .01). LBBP implantation is associated with myocardial injury. Asymptomatic troponin release following LBBP is less than or comparable to other interventional electrophysiology procedures.

State of Fluoroless Procedures in Cardiac Electrophysiology Practice.

In the past decade, the use of interventional electrophysiological (EP) procedures for the diagnosis and treatment of cardiac arrhythmias has exponentially increased. These procedures usually require fluoroscopy to guide the advancement and frequent repositioning of intracardiac catheters, resulting in both the patient and the operator being subjected to a considerable degree of radiation exposure. Although shielding options such as lead gowns, glasses, and pull-down shields are useful for protecting the operator, they do not lessen the patient’s level of exposure. Furthermore, the prolonged use of lead gowns can exponentiate the onset of orthopedic problems among operators. Recent advancements in three-dimensional cardiac mapping systems and the use of radiation-free imaging technologies such as magnetic resonance imaging and intracardiac ultrasound allow operators to perform EP procedures with minimal or even no fluoroscopy. In this review, we sought to describe the state of fluoroless procedures in EP practice.

2018 Korean Guidelines for Catheter Ablation of Atrial Fibrillation: Part III

Catheter ablation of atrial fibrillation (AF) is one of the most complex interventional electrophysiological procedures. The success of AF ablation is based in large part on freedom from AF recurrence based on electrocardiography (ECG) monitoring. Arrhythmia monitoring can be performed with the use of noncontinuous or continuous ECG monitoring tools. AF ablation is an invasive procedure that entails risks, most of which are present during the acute procedural period. However, complications can also occur in the weeks or months following ablation. Recognizing common symptoms after AF ablation and distinguishing those that require urgent evaluation and referral to an electrophysiologist is an important part of follow-up after AF ablation. This section reviews the complications associated with catheter ablation procedures performed to treat AF. The types and incidence of complications are presented, their mechanisms are explored, and the optimal approach to prevention and treatment is discussed. Finally, surgical and hybrid AF ablation technology and the indications for concomitant open or closed surgical ablation of AF, stand-alone and hybrid surgical ablation of AF are covered in this section. Key words: atrial fibrillation; surgical ablation; follow-up; outcome; complication

Flexible robotic catheters in the visceral segment of the aorta: advantages and limitations.

Flexible robotic catheters are an emerging technology which provide an elegant solution to the challenges of conventional endovascular intervention. Originally developed for interventional cardiology and electrophysiology procedures, remotely steerable robotic catheters such as the Magellan system enable greater precision and enhanced stability during target vessel navigation. These technical advantages facilitate improved treatment of disease in the arterial tree, as well as allowing execution of otherwise unfeasible procedures. Occupational radiation exposure is an emerging concern with the use of increasingly complex endovascular interventions. The robotic systems offer an added benefit of radiation reduction, as the operator is seated away from the radiation source during manipulation of the catheter. Pre-clinical studies have demonstrated reduction in force and frequency of vessel wall contact, resulting in reduced tissue trauma, as well as improved procedural times. Both safety and feasibility have been demonstrated in early clinical reports, with the first robot-assisted fenestrated endovascular aortic repair in 2013. Following from this, the Magellan system has been used to successfully undertake a variety of complex aortic procedures, including fenestrated/branched endovascular aortic repair, embolization, and angioplasty.

Updated Survey on Interventional Electrophysiology: 5-Year Follow-Up of Infrastructure, Procedures, and TrainingPositions in Germany.

This study provides an update and comparison to a 2010 nationwide survey on cardiac electrophysiology (EP), types and numbers of interventional electrophysiological procedures, and training opportunities in2015. In 2010, German cardiology centers performing interventional EP were identified and contacted to provide a survey on cardiac EP. German cardiology centers performing interventional EP in 2015 were identified from quality reports and contacted to repeat the 2010 questionnaire. A majority of 131 centers (57%) responded. EP (ablation procedures and device therapy) was mainly part of a cardiology department (89%) and only independent (with its own budget) in 11%. The proportion of female physicians in EP training increased from 26% in 2010 to 38% in 2015. In total, 49,356 catheter ablations (i.e., 81% of reported ablations in 2015) were performed by the responding centers, resulting in a 44% increase compared with 2010 (themedian number increased from 180 to 297 per center). Atrial fibrillation (AF) was the most common arrhythmia interventionally treated (47%). At 66% of the centers, (at least) 2 physicians were present during most catheter ablations. A minimum of 50 (75) AF ablations were performed at 80% (70%) of the centers. Pulmonary vein isolation with radiofrequency point-by-point ablation (62%) and cryoablation (33%) were the preferred ablation strategies. About one-third of centers reported surgical AF ablations, with 11 centers (8%) performing stand-alone surgical AF ablations. Only one-third of the responding 131 centers fulfilled all requirements for training center accreditation. Comparing 2010 with 2015, an increasing number of EP centers and procedures in Germany are registered. In 2015, almost every second ablation was for therapy for AF. Thus, an increasing demand for catheter ablation is likely, but training opportunities are still limited, and most centers do not fulfil recommended requirements for ablation centers.

Statistics on the use of cardiac electronic devices and interventional electrophysiological procedures in Africa from 2011 to 2016: report of the Pan African Society of Cardiology (PASCAR) Cardiac Arrhythmias and Pacing Task Forces.

AimsTo provide comprehensive information on the access and use of cardiac implantable electronic devices (CIED) and catheter ablation procedures in Africa.Methods and resultsThe Pan-African Society of Cardiology (PASCAR) collected data on invasive management of cardiac arrhythmias from 2011 to 2016 from 31 African countries. A specific template was completed by physicians, and additional information obtained from industry. Information on health care systems, demographics, economics, procedure rates, and specific training programs was collected. Considerable heterogeneity in the access to arrhythmia care was observed across Africa. Eight of the 31 countries surveyed (26%) did not perform pacemaker implantations. The median pacemaker implantation rate was 2.66 per million population per country (range: 0.14–233 per million population). Implantable cardioverter-defibrillator and cardiac resynchronization therapy were performed in 12/31 (39%) and 15/31 (48%) countries respectively, mostly by visiting teams. Electrophysiological studies, including complex catheter ablations were performed in all countries from Maghreb, but only one sub-Saharan African country (South Africa). Marked variation in cost (up to 1000-fold) was observed across countries with an inverse correlation between implant rates and the procedure fees standardized to the gross domestic product per capita. Lack of economic resources and facilities, high cost of procedures, deficiency of trained physicians, and non-existent fellowship programs were the main drivers of under-utilization of interventional cardiac arrhythmia care.ConclusionThere is limited access to CIED and ablation procedures in Africa. A quarter of countries did not have pacemaker implantation services, and catheter ablations were only available in one country in sub-Saharan Africa.

A Decade of Information on the Use of Cardiac Implantable Electronic Devices and Interventional Electrophysiological Procedures in the European Society of Cardiology Countries: 2017 Report from the European Heart Rhythm Association.

The aim of this analysis was to provide comprehensive information on invasive cardiac arrhythmia therapies in the European Society of Cardiology (ESC) area over the past 10 years. The European Heart Rhythm Association (EHRA) has collected data on invasive arrhythmia therapies since 2008. This year 53 of the 56 ESC member countries provided data for the EHRA White Book. Here we present updated data on procedure rates together with information on demographics, economy, vital statistics, local healthcare systems and training activities. Considerable heterogeneity in the access to invasive arrhythmia therapies still exists across the five geographical ESC regions. In 2016, the device implantation rates per million population were 3-6 times higher in the Western region than in the non-European and Eastern ESC member countries. Catheter ablation activity was highest in the Western countries followed by the Northern and Southern areas. In the non-European countries, atrial fibrillation ablation rate was more than tenfold lower than in the European countries. On the other hand, the growth rate over the past ten years was highest in the non-European and Eastern countries. In some Eastern European countries with relative low gross domestic product the procedure rates exceeded the average values. It was encouraging to note that during the past decade the growth in invasive arrhythmia therapies was greatest in the areas historically with relatively low activity. Nevertheless, there is substantial disparity and continued efforts are needed to improve harmonization of cardiac arrhythmia therapies in the ESC area.

Utility and Safety of Combined Interventional Catheterization and Electrophysiology Procedures in a Children's Hospital.

Interventional cardiac catheterization (cath) and electrophysiology (EP) procedures are not routinely performed together. There are several perceived barriers affecting this practice, though there are also advantages for both the patient and practitioner to a combined approach. This was a single-center retrospective study reviewing combined cath and EP procedures with a preprocedural intention to intervene at Texas Children's Hospital from 2001 to 2014. We excluded procedures in which the intended procedure was purely diagnostic in nature. A total of 121 patients requiring 125 procedures were identified, of which 61 patients underwent 62 procedures that met our inclusion criteria. Potential subgroups of interest included adult congenital heart disease patients (26% of cohort), single ventricle anatomy (34%), and heterotaxy (19%) and collectively 58% of procedures involved a patient in one of these groups. The combined nature of the procedure did not preclude a cath or EP intervention in any patient. There were no mortalities. There were three adverse events, affecting 4.8% of procedures. Combined interventional cardiac cath and EP procedures in pediatric patients and those with congenital heart disease can be performed safely in a high-volume center. These combined procedures save patients the risk and inconvenience of multiple procedures, and further investigation into cost savings is warranted.

Radiation dose among different cardiac and vascular invasive procedures: The RODEO study

BackgroundInterventional radiology and cardiology procedures contribute significantly to the collective dose of radiation exposure from medical interventions. Recent and dedicated studies comparing directly these procedures in term of patient radiation exposure are lacking. Our aim was to compare radiation exposure among different interventional procedures performed under fluoroscopic guidance. MethodsThe RODEO study (NCT: 02972736) is an international observational retrospective multicenter study enrolling all patients undergoing diagnostic or interventional procedures performed by different interventional operators (i.e. radiologists, interventional cardiologists or electrophysiologists) in 6 centers, without exclusion criteria. The primary end-point of the study was the comparison of dose area product (DAP) among interventional cardiology, electrophysiology or interventional radiology procedures. ResultsA total of 17,711 procedures were included in the study: 13,522 interventional cardiology, 2352 electrophysiology and 1864 interventional radiology procedures. The highest DAP values were observed for interventional radiology procedures (74Gy∗cm2 [Interquartile range 27–178Gy∗cm2]), followed by interventional cardiology (40Gy∗cm2 [22–78Gy∗cm2]) and electrophysiology procedures (13Gy∗cm2 [4–44Gy∗cm2], p<0.0001). In term of specific procedures, the highest DAP values were observed in structural or valvular cardiac procedures (134Gy∗cm2 [51–260Gy∗cm2]) whereas the lowest DAP values in pacemaker insertion (11Gy∗cm2 [4–28Gy∗cm2]). ConclusionIn this large multicenter study, the highest radiation exposure was observed in procedures performed by interventional radiologists. However, among specific procedures, structural or valvular cardiac procedures were associated with the highest radiation exposure.

Access to and clinical use of cardiac implantable electronic devices and interventional electrophysiological procedures in the European Society of Cardiology Countries: 2016 Report from the European Heart Rhythm Association.

The aim of this analysis was to provide comprehensive information on the access to and use of cardiac implantable electronic device (CIED) and catheter ablation therapy in the European Society of Cardiology (ESC) area. The European Heart Rhythm Association (EHRA) has been collecting descriptive and quantitative data on invasive arrhythmia therapies since 2008. This year 50 of the 56 ESC member countries provided data for the EHRA White Book. Up-to-date information on procedure rates for the last 5 years together with information on demographics, economy, vital statistics, local healthcare systems, and training activities is presented for each country and the 5 geographical ESC regions. Our analysis indicated that considerable heterogeneity in the access to arrhythmia therapies still exists across the ESC area. In 2015, the CIED implantation rates per million population were highest in the Western followed by the Southern and Northern European countries. The catheter ablation activity was largest in the Western followed by the Northern and Southern areas. Overall, the procedure rates were 3-10 times higher in the European than in the non-European ESC countries. Economic resources were not the only driver for utilization of arrhythmia therapies as in some Eastern European countries with relative low gross domestic product the procedure rates exceeded the average values. These data will help the healthcare professionals and stakeholders to identify and to understand in more depth the trends, disparities, and gaps in cardiac arrhythmia care and thereby promote harmonization of cardiac arrhythmias therapies in the ESC area.

The establishment of comprehensive cardiac care centre

Salman Abdulla Aldabbous Cardiac Centre in Aladan hospital was inaugurated in February 2010. Constructed with generous grant from Mr. Salman Abdulla Aldabbous, the centre was a progression for the cardiology division services at Aladan hospital which till then was part of the internal medicine department. The centre serves a population of 1.3 million in the Governorates of Ahmadi and Mubarak Alkabeer in the State of Kuwait. The centre includes of 20 bed coronary care unit, 40 beds for inpatients, 2 catheterization suites, 2 operating room suites and 3 bed cardiac surgical intensive care unit. Tremendous amount of work went into staffing it before and after its opening in 2010. Our vision was to equip it in a way to become a standalone centre of excellence in the country to be able to provide all types of cardiac services including diagnostic and interventional cardiac catheterization procedures, electrophysiology procedures and cardiac surgery. This was a huge challenge that involved employing trained human resources from nurses, technicians and doctors as well as …
