Long-term outcomes of ovary preserving procedure for neonatal ovarian cysts

Objective: We aim to evaluate the long-term outcomes of ovarian preserving surgery for neonatal ovarian cysts. Method: The clinical data of neonatal ovarian cysts treated in our hospital from January 2015 to December 2022 were retrospectively analyzed. Results: Our study included 22 patients, of which 21 were unilateral and 1 was bilateral. There were 13 cases of simple cysts and 9 cases of complex cysts, and one cyst changed from simple to complex. The mean largest diameter of simple cysts was 5.7±2.1cm, and that of complex cysts was 4.6±2.0cm. There was no significant difference between the two groups (P=0.2264). Among the 22 patients, 21 underwent laparoscopic cystectomy. The only patient with bilateral cysts underwent percutaneous drainage of the right simple cyst. Twenty-one histological specimens were reviewed, of which 18(85.7%) contained viable ovarian tissues. Five cases lost follow-up after surgery, and the remaining 17 cases had a follow-up period of 6 months to 5 years. The last ultrasound follow-up showed that 9 cases had bilateral normal ovaries, and 8 cases lost the ipsilateral ovary. The ovarian preservation rate of simple cyst was 90% (9/10), which was significantly higher than that of complex cyst (12.5%, 1/8) (P=0.003). Conclusions: Simple cysts (≥ 4cm) had an excellent prognosis, with a long-term ovarian preservation rate of 90%. The long-term ovarian preservation rate of complex cysts after surgery was relatively low. Our study suggested that surgical treatment did not increase the chances of preserving the ovaries of patients with complex cysts.

Development of a Uniform Apheresis Case Report Form forStandardized Collection of Apheresis Data.

Apheresis is performed worldwide for an increasing number of indications. The development of common data elements (CDE) for apheresis related areas may facilitate conduct of new research, enhance quality initiatives including benchmarking, and improve patient care. This report describes the systematic development of the Uniform Apheresis Case Report Form (UACRF) as part of the Apheresis in the United States (ApheresUS) program. A consensus panel of 17 diverse experts in apheresis, related specialties, and electronic case report form (eCRF), and database development was assembled. The panel met via online conferencing from November 17, 2020 to December 1, 2021. A draft document was posted online for public comment from October 11, 2021 to November 10, 2021. Feedback was collected using an online survey tool. The consensus panel revised the UACRF. This version was converted to an eCRF with additional changes made to improve usability in this format. The final version of the UACRF was created on August 24, 2023. The UACRF contains 16 modules: procedure and subject eligibility, patient demographics, general procedure information, laboratory parameters, vascular access, common procedure elements, eight procedure specific modules (mononuclear cell collection and seven therapeutic modalities), outcomes, and site information. A total of 137 data elements were created, including 57 with one or more subelements. The UACRF is the first systematic attempt to develop CDE for therapeutic apheresis and white blood cell collections. Further validation of the UACRF is necessary to confirm the tool's ability to collect the relevant data elements and determine the usability of the form.

Impact of Diabetes Mellitus on Bifurcation Percutaneous Coronary Intervention: Insights From The PROGRESS-BIFURCATION Registry

The impact of diabetes mellitus (DM) on the outcomes of bifurcation percutaneous coronary intervention (PCI) has received limited study. We compared the procedural characteristics and outcomes of patients with and without diabetes mellitus among 1,302 bifurcation PCIs (1,147 patients) performed at five centers between 2013-2024. The prevalence of diabetes mellitus was 33.8% (n=388). Patients with diabetes were younger, had more cardiovascular risk factors and higher angiographic complexity, including more main vessel calcification and more frequent stenoses in the left main, proximal left anterior descending and right coronary artery. There was no difference in technical (95.5% vs 94.9%, p = 0.613) or procedural success (90.2% vs 91.3%, p = 0.540); provisional stenting was used less frequently in diabetic patients (64.5% vs 71.1%, p = 0.015). Diabetic patients had higher rates of repeat in-hospital PCI and acute kidney injury. Other in-hospital outcomes were similar after adjusting for confounders. During a median follow-up of 1,095 days diabetes was independently associated with higher incidence of major adverse cardiovascular events (hazard ratio [HR]: 2.04, 95% confidence intervals [CI]: 1.52, 2.72, p < 0.001), myocardial infarction (HR: 1.94, 95% CI: 1.05, 3.25, p = 0.033), death (HR: 2.26, 95% CI: 1.46, 3.51, p < 0.001), target (HR: 1.6, 95% CI: 1.01, 2.66, p = 0.045) and non-target (HR: 2.00, CI: 1.06, 3.78, p = 0.032) vessel revascularization. Compared with non-diabetics, patients with diabetes mellitus undergoing bifurcation PCI had higher risk of in-hospital repeat-PCI and major adverse cardiac events during follow-up.Diabetes mellitus (DM) increases the risk of coronary artery disease (CAD) and has been associated with more complex and multifocal coronary lesions (1,2). Percutaneous coronary intervention (PCI) in diabetic patients has been associated with high short- and long-term incidence of adverse events in some (3) but not all (4,5) studies. In a study by Xue et al. newly diagnosed and previously known diabetes patients undergoing PCI had higher incidence of follow-up major adverse cardiac events (MACE) rates compared with non-diabetics (6). Bifurcation lesions account for 15-20% of all PCIs and can be challenging to perform (7-9). Bifurcation PCI has been associated with lower technical and procedural success (10) and higher adverse outcomes (11,12). While there are published data on the impact of diabetes mellitus in patients undergoing PCI (13), there is limited data on its impact on bifurcation PCI (Table 1). We examined the impact of diabetes mellitus on the outcomes of bifurcation PCI in a multicenter registry.

Patient Perception and Experience of Laparoscopic Excision vs. Ablation of endometriosis: a crowd-sourced comparative evaluation of symptom and Quality of Life outcomes

Study Objective: To compare laparoscopic Ablation and Excision in terms of symptom and Quality of Life outcomes as perceived by endometriosis patients. DesignA Cohort, Method comparison Questionnaire-based study SettingEndometriosis-focused Social Media site PatientsEndometriosis patients with history of Laparoscopic Ablation and Excision. InterventionsOn-line questionnaire focused on pre and post procedure (ablation and excision) outcomes across 63 measures in 5 realms: Physical Symptoms, Functional Impact, Psycho-emotional Impact, Social/Sexual Impact, Economic/Educational Impact. Measurements and Main Results232 respondents with surgical history that included laparoscopic ablation and excision (without concomitant or interposed hysterectomy) identified for ablation only physical symptom improvement of 11.3% and 8.5% for dysmenorrhea and menorrhagia respectively. Ablation provided no significant improvement in any other physical symptom measure. Excision was identified as providing improvements across all symptoms ranging from 28% to 46%.In terms of Functional Impact, ablation provided non-significant improvements or worsening of status. Excision demonstrated significant improvement for patients across most measures of Functional Impact.In terms of Psycho-emotional Impact, a worsening of QoL status is identified in 23 of 24 measures following ablation. Excision demonstrated improvement in 22 of 24 measures.For Social-Sexual Impact, ablation resulted in worsened status across all measures with excision demonstrating improvements in all measures, significantly so in most.For Economic/Educational Impact, significant worsening of measures or insignificant improvements were demonstrated following ablation. Excision demonstrated significant improvement in most measures.In all realms, pre-Excision status was worse than pre-Ablation.Allowing for a more focused comparison of ablation and excision, 113 respondents with a surgical history of ablation sequentially followed by excision demonstrated outcomes similar to the larger group: overall worsening of status resulting from ablation and overall improvement in status following excision with pre-Excision morbidity higher than pre-Ablation. ConclusionIn this cohort of patients undergoing laparoscopic endometriosis excision after having undergone endometriosis ablation, the former demonstrated greater beneficial effect over a broad spectrum of symptom and QoL measures.

Comprehensive surgical technique for the neonatal and infant Ross Konno procedure – technical pearls

The Ross Konno procedure is a technically demanding operation in neonates and infants, particularly in small babies and those with significant aortic annular and left ventricular outflow tract hypoplasia. There are several key technical considerations for harvesting the pulmonary autograft with care to preserve the left main coronary artery and the septal perforating arteries in addition to ensuring an optimal muscle cuff on the base of the autograft. Accommodation of the autograft deep within the native aortic valve annulus by performing an appropriate Konno incision and ensuring correct suture placement is essential. Adequate epicardial mobilisation and subsequent reimplantation of the coronary arteries into the autograft neo-aortic root is also a key consideration given the significant radial displacement of the coronary arteries required to accommodate the often much larger autograft into the space of a previously very small aortic root. Although the overall technical details of the Ross Konno procedure have previously been described by others the specific granular technical detail and meticulous approach required for a successful procedural outcome in neonates and infants remains to be fully elucidated. Key technical considerations such as suture spacing, positioning of the autograft with in the Konno incision and management of the coronary arteries require detailed description. We describe our institutional approach to the Ross Konno procedure in neonates and infants to clarify these important technical considerations.

Impact of body mass index on in-hospital outcomes in patients receiving leadless pacemakers: A five-category analysis

BackgroundThe adoption of leadless pacemakers (LPMs) is increasing, yet the impact of body mass index (BMI) on procedural outcomes remains underexplored. ObjectiveThe purpose of this study was to explore the impact of BMI on in-hospital outcomes for patients receiving LPM implantation. MethodsData from the National Inpatient Sample from 2018–2021 were analyzed for patients older than 18 years who underwent LPM implantation, with specific inclusion and exclusion criteria applied. Patients were identified using International Classification of Diseases 10th Revision codes and categorized into BMI groups: underweight, normal, overweight, obese, and morbidly obese. The primary outcome assessed was in-hospital mortality. Secondary outcomes included blood transfusion, pericardial complications, infection/inflammation, removal/revision, and other complications. ResultsThe study included 3832 patients who underwent LPM implantation between 2018 and 2021, weighted to represent 19,610 patients, with 3540 having an appropriate BMI designation. Mortality was lower in the obese group (2.3%) compared to the nonobese group (2.7%) (adjusted odds ratio [aOR] 0.462, 95% confidence interval [CI] 0.259–0.623, P = .009). Compared to the normal weight group, those categorized as overweight, obese, and morbidly obese demonstrated a lower risk of in-hospital mortality (aOR 0.432, 95% CI 0.299–0.734, P = .009; aOR 0.465, 95% CI 0.238–0.721, P <.001; aOR 0.299, 95% CI 0.153–0.586, P <.001, respectively). ConclusionThese findings support the existence of the obesity paradox in patients with LPM implantation, where higher BMI categories are associated with improved mortality outcomes, meeting our prespecified primary endpoint. Further studies are needed to clarify the mechanisms behind these observations.

Emergency Surgical Management of Meningiomas: Factors Affecting Early Outcomes and Complications

Abstract Objective Intracranial meningiomas constitute a third of all brain tumors and are among the most common indications for neurosurgical procedures performed worldwide. Most meningiomas present with an indolent, longstanding history. However, the data on outcomes of emergency surgeries for meningioma is limited. This study aims to present our experience of urgent surgical intervention in patients with meningiomas presenting acutely. We also analyze the factors influencing early neurological outcomes and complications. Materials and Methods All nonelective meningioma surgeries done on an emergency basis between January 2015 and December 2019 were retrospectively reviewed. Patients' demography, clinical, and radiological details were recorded for analysis. The surgical procedure, complications, and follow-up outcomes were also included for statistical comparison. Results Forty-four patients qualified for the study with a mean age of 49.4 ± 13.4 years. The average presenting Glasgow Coma Scale (GCS) was 13; 47.7% of cases presented with altered sensorium. The most common lesion location was convexity (25, 56.8%), and the mean tumor volume was 74.1 ± 36.5 mL. Gross peritumor edema with mass effect was seen in 16 patients (36.4%). The mean Karnofsky Performance Status at 3 months' follow-up was 89.3 ± 18.2. Patient age and tumor size did not affect outcomes. The presenting GCS of &lt; 15 (odds ratio [OR] 8.8, confidence interval [CI] 0.95–80.72, p 0.03) and the occurrence of postoperative complications (OR 25.71, CI 2.65–249.2, p 0.001) were associated with unfavorable outcomes. Although not statistically significant, a poor tumor grade was also associated with worse clinical outcomes (p 0.20). Conclusion Emergency meningioma surgery has comparable outcomes and complication rates with routine elective procedures. Grade II/III meningiomas are more likely to present with acute neurological deterioration and carry a relatively worse prognosis. Poor presenting GCS and postoperative complications are the most critical factors associated with poor patient outcomes in our study.

Impact of Either Trendelenburg or Reverse Trendelenburg Positioning for Ureteroscopy Lithotripsy Procedures: A Systematic Review and Meta-Analysis.

Urologists encounter multiple challenges in managing ureteral stones with ureteroscopic laser lithotripsy. This meta-analysis assesses the effectiveness of alternative surgical positioning, Reverse Trendelenburg (RevTren) and Trendelenburg (Tren), in reducing stone migration and enhancing outcomes compared with standard dorsal lithotomy positioning. A systematic review was conducted following PRISMA guidelines, searching Medline, Embase, Scopus, Cochrane, and WoS up to March 2024. This review focused on studies evaluating RevTren or Tren positioning during ureteroscopic lithotripsy compared with standard dorsal lithotomy, analyzing end points such as stone migration, conversion rates, success rates, complications, and operative time. Of 137 studies identified, 8 met the inclusion criteria, encompassing 1374 patients. RevTren significantly reduced ureteral stone migration (odds ratio [OR], 0.20; 95% CI, 0.08-0.47), lowered the need for conversion to a flexible ureteroscope (OR, 0.28; 95% CI, 0.12-0.67), and improved success rates (OR, 2.90; 95% CI, 1.88-4.48). Tren increased migration of ureteral and calyceal stones toward upper renal calyces (OR, 2.12; 95% CI, 1.48-3.04) and achieved a higher success rate (OR, 3.56; 95% CI, 2.15-5.92). Complications were comparable across all positions. Adjusting patient positioning during ureteroscopic laser lithotripsy can enhance procedure outcomes. RevTren effectively reduces ureteral stone migration and the necessity for flexible ureteroscopes, whereas Tren facilitates ureteral and calyceal stone migration toward upper calyces, increasing success rates. Both positioning techniques offer significant advantages over standard positioning and can be safely adopted in clinical practice without compromising patient safety.

Impact of smoking on procedural outcomes and all-cause mortality following acute myocardial infarction: A misleading early-stage pseudoparadox with ultimately reduced survival

BackgroundSmoking has conflicting results on outcomes following acute myocardial infarction (AMI). We evaluated the independent influence of smoking status on patient outcomes. MethodsWe included patients with AMI undergoing invasive coronary angiography with available self-reported smoking status. The incidence of death of any cause was evaluated during a median follow-up of 1.14 years (range 0.36–3.40 years). Association between smoking status and long-term mortality was evaluated using multivariable adjusted Cox regression analysis. ResultsFrom 1612 AMI patients (aged 65.7 ± 13.3 years, 72.1 % male), 378 patients (23.4 %) were current-smokers, 311 (19.3 %) ex-smokers, and 923 (57.3 %) non-smokers. Compared with non-smokers, current-smokers were younger (68.5 ± 13.0 vs. 58.6 ± 12.5, p < 0.0001) and more frequently presented with STEMI (21.6 % vs. 35,4 %, p < 0.0001), while ex-smokers with similar frequency of STEMI-manifestation as non-smokers (22.5 %, p = 0.79) constituted an intermediate-group in terms of age (65.8 ± 11,6 years). Although smoking status was not significantly associated with long-term survival in unadjusted-analysis, active-smokers had 56 % higher long-term mortality than non-smokers when adjusting for age, gender, medications and other traditional risk factors, whereas ex-smokers possessed comparable survival probability (current-smokers: 1.56[1.14–2.14], p = 0.006, ex-smokers 1.16[0.84–1.59], p = 0.37). Current-smokers had unadjusted lower NT-proBNP and modestly higher absolute in-hospital left ventricular global longitudinal strain (LV GLS) values that did not differ among groups after the same adjustments (NT-proBNP: −0.08[-0.31; 0.15], p = 0.5, LV GLS: 0.65[-0.26; 1.55], p = 0.16). ConclusionActive smoking is associated with increased adjusted long-term mortality, earlier onset and more frequent manifestation as STEMI, compared to non-smoking. Comparable adjusted results for LV GLS and NT-proBNP between groups support the presence of the pseudoparadox.

Short-term and Long-term Clinical Outcomes of Combined Caudate Lobectomy for Intrahepatic Cholangiocarcinoma Involving the Hepatic Hilus: A Propensity Score Analysis.

Extended hepatectomy combined with caudate lobe resection has been approved for the radical resection of hilar cholangiocarcinoma. There was a lack of credible research on the clinical value of caudate lobectomy (CL) for intrahepatic cholangiocarcinoma involving the hepatic hilus when combined with hepatectomy. We aimed to compare the short-term and long-term outcomes of the combined procedure with those of only CL for curative resection of intrahepatic cholangiocarcinoma involving the hepatic hilus. This single-center retrospective cohort study of patients with hilar cholangiocarcinoma was conducted from January 2007 to December 2021. Patients who underwent radical resection were enrolled in this study. The short-term and long-term clinical outcomes of the groups were compared before and after propensity score matching (PSM). A total of 282 patients were included. There were no statistically significant differences in perioperative clinical outcomes between the CL group and the non-CL group before and after PSM. Compared to patients in the non-CL group, patients in the CL group had significantly longer overall survival before and after PSM (p=0.007 before PSM, p=0.033 after PSM). Moreover, compared to the non-CL group, the CL group had longer disease-free survival before and after PSM (p<0.001 before PSM, p=0.019 after PSM). The postoperative complications of the CL group were comparable to those of the non-CL group. CL improved the long-term survival of patients with intrahepatic cholangiocarcinoma involving the hepatic hilus when combined with hepatectomy. Therefore, hepatectomy combined with caudate lobe resection should be performed for patients with hilar cholangiocarcinoma.

Subjective outcomes of female genital cosmetic procedures: a prospective study with a median follow-up of 18 months

Aims: To investigate the affects of labiaplasty and/or vaginoplasty on sexual function and satisfaction, as well as the potential to improve body image and genital self-image. Methods: A total of 131 heterosexual sexually active women receiving either a vaginoplasty and/or labioplasty were included in the study population. Patients were subsequently divided into three groups: labioplasty (LP) (n=44), vaginoplasty (VP) (n=44), and labioplasty-vaginoplasty (LVP) (n=43) for statistical evaluation. All participants were administered preoperatively and postoperatively validated questionnaires including Body Image Scale (BIS); Female Sexual Function Index (FSFI), Sexual Quality of Life Questionnaire-Female (SQOL-F), Female Sexual Distress Scale (FSDS), Female Genital Self-Image Scale (FGSIS), and Quality of Sexual Experience Scale (QSES). Results: The median follow-up was 18 months after the female genital cosmetic procedure (FGCP). FGSIS, BIS, SQOL-F, QSES, and FSDS postoperative questionnaires total scores improved significantly in the LP, VP, and LVP groups. FSFI postoperative total scores improved among all groups, but no statistically significant difference was detected in the LP group, unlike the VP and LVP groups. No intraoperative complications occurred. Postoperative complications were detected in 2 (4.5%) women in the LP group and 1 (2.3%) woman in the LVP group. These complications were wound dehiscence (

Serial Transverse Enteroplasty (STEP) for Short Bowel Syndrome (SBS) in Children: A Multicenter Study on Long-term Outcomes

ObjectivesShort Bowel Syndrome (SBS), secondary to various underlying diseases, is one of the main causes of intestinal failure in children. Surgical management by serial transverse enteroplasty (STEP), is feasible in selected cases, but results on long-term follow-up are scarce. The aim of this study was to report long-term outcomes of the STEP procedure in children with SBS. MethodsWe performed a multicenter national retrospective study reviewing medical charts of children who underwent a STEP technique between 2000 and 2022 in 6 university hospitals. Collected data included demographics, SBS history, surgical procedures, nutritional support (enteral or parenteral), STEP management, complications, and outcomes (nutritional support, digestive symptoms, growth). ResultsSTEP was performed in 36 SBS, resulting from 14 gastroschisis, 10 intestinal atresia, 8 necrotizing enterocolitis (NEC), 2 midgut volvulus, and 2 intestinal Hirschsprung disease. Median age at first STEP was 10.8 months [4.5; 63.8]. Bowel length significantly increased (47 vs 70 cm, p < 0.01), with a median gain of 16 cm [11; 25] or 34%. At surgery, 33 children had parenteral nutrition (PN). A second STEP was performed in 11 patients, at a median age of 4.2 years [2.8; 6.8]. One patient underwent a third STEP. Two children required intestinal transplantation. Median follow-up was 7 years [4.4;11.4]. Out of 33 children requiring PN before surgery, 14 children were weaned off PN. The remaining 19 children still required PN, but their dependency decreased by 19%. Out of 17 children presenting severe intestinal dilations and bacterial overgrowth, 12 became asymptomatic. Out of 20 with chronic obstructive symptoms, 8 patients still required supplementary PN whereas 12 achieved complete enteral autonomy, including 3 requiring supplementary enteral support. ConclusionSTEP technique remains a surgical option in the management of these children, enabling a decrease in PN dependency, resulting in weaning off PN in some cases, as well as an improvement of clinical symptoms. Type of StudyRetrospective multicenter observational study. Level of EvidenceLevel 3.

Short Term Outcomes of a Prospective Registry in Popliteal and Infrapopliteal Endovascular Interventions for Chronic Limb Threatening Ischaemia

The prevalence of chronic limb threatening ischaemia (CLTI) is increasing worldwide, resulting in the need for more patients undergoing revascularisation, especially for below the knee pathology. Nevertheless, prospective data on below the knee endovascular interventions are lacking. The aim of the study was to provide large scale, real world data on procedural and short term outcomes of popliteal and infrapopliteal endovascular interventions in patients with CLTI. This study is an analysis of the first 1 000 interventions of the Dutch Chronic Lower Limb-Threatening Ischemia Registry (THRILLER). It includes all patients with CLTI undergoing popliteal or infrapopliteal endovascular revascularisation in seven hospitals in the Netherlands. The primary outcomes were limb salvage and amputation free survival (AFS) at three months estimated with the Kaplan-Meier method. Secondary outcomes were procedural complications and primary patency. Between February 2021 and July 2023, 1 000 endovascular procedures were performed in 840 patients (947 limbs), treating 486 popliteal and 1 209 tibial lesions. Wound, Ischemia, and foot Infection (WIfI) stages 1 - 4 were present in 16.8%, 17.2%, 25.4%, and 40.6% of the limbs, respectively. Technical success was hampered by arterial perforation, acute thrombosis, and distal embolisation in 8.7%, 1.0%, and 2.3% of the interventions, respectively. Limb salvage was 100.0%, 96.9%, 94.9%, and 86.1% (p < .001), whereas AFS was 96.9%, 93.2%, 86.6%, and 76.4% for WIfI stages 1 - 4 at three months (p < .001), respectively. Primary patency at the 6 - 8 week visit was 86.4% for popliteal and 74.3% for tibial lesions, respectively. THRILLER presents a large prospective database on outcomes of CLTI endovascular interventions. Popliteal and infrapopliteal endovascular revascularisation for CLTI is safe. Interventions with initial technical success have high rates of limb salvage and survival at three months. The WIfI classification provides a reliable instrument to predict limb salvage and AFS independently at three months.

Outcomes of atrial fibrillation ablation in community hospitals with and without onsite cardiothoracic surgery availability.

Limited data exist on outcomes of atrial fibrillation (AF) catheter ablation based on hospital setting and, specifically, the availability of onsite cardiothoracic surgery (CTS). We aimed to describe the characteristics and outcomes of catheter ablation for AF performed at a facility with and without CTS. This was a retrospective study of consecutive patients who underwent catheter ablation for AF at hospital with (CTS) and without cardiothoracic surgery (N-CTS) from January 2011 through December 2019. Clinical and procedural characteristics, complications, and 1-year outcomes, including clinical events and AF recurrence, were collected. There were 326 unique patients who underwent an index AF ablation procedure: 206 CTS patients and 120 N-CTS patients. There were no differences inoverall cardiac complications (2.5% vs. 5.8%), including mapping catheter entrapment requiring open-heart surgery (0% vs. 0.5%), pericardial effusion requiring pericardiocentesis (0.8% vs. 0.5%), hemopericardium (1.7% vs. 0.5%), acute myocardial infarction (0% vs. 1.0%), and sinus node injury (0% versus 0.5%) (all P values > .05)between N-CTS and CTS patients. Likewise, overall noncardiac complications (20.7% vs. 19.8%, P = .85), including bleeding, cerebrovascular accident, and phrenic or vagus nerve injury, were similar between N-CTS and CTS hospitals. Also, 1-year cumulative Kaplan-Meier estimates of overall AF recurrence (11.6% vs. 16.4%; log-rank P = 0.21; HR 1.47; 95% CI, 0.79-2.74) were not statistically significant between N-CTS and CTS hospitals. Catheter ablation procedure is safe and effective regardless of onsite CTS presence, and there were no significant differences between the two hospital settings.
