A comparison of different dosing regimen of intravenous paracetamol for hemodynamically significant patent ductus arteriosus closure in premature neonates

To compare the efficacy of low vs conventional dose intravenous paracetamol in early closure of haemodynamically significant patent ductus arteriosus within 7 days of life. Preterm infants (<32 weeks of gestation) having echocardiographic evidence of hsPDA were given low dose (15 mg/kg initially followed by 7.5 mg/kg every 6 hourly) vs conventional dose (15 mg/kg every 6 hourly) for 5-7 days. In total, 56 infants (28 in each group) were enrolled. Ductal closure was achieved in 96% infants in the low-dose group and 100% infants in the conventional group (P = 1.00). Secondary outcomes, including ductal reopening and need for the second course of medical treatment (21% vs 3.5%, P = 0.1), median duration of hospital stay [30 (15, 43.5) vs 27 (18.5,45), P = 0.64], cumulative oxygen requirement [17.5 (7, 25) vs 14 (8.5, 25), P = 0.89], mortality (10.7% vs 25%, P = 0.29) and other morbidities, were comparable in both the groups. Median paracetamol levels were comparable in both the groups [53.4 μg/L (47, 2,70) vs 62.5 (55.6, 81.2), P = 0.67]. Low-dose paracetamol was non-inferior to conventional dose paracetamol for early ductal closure in preterm infants.

Cardiorespiratory Instability after Percutaneous Patent Ductus Arteriosus Closure: A Multicenter Cohort Study

ObjectiveTo evaluate post-procedural clinical characteristics of preterm infants undergoing transcatheter patent ductus arteriosus (PDA) closure, including oxygenation/ventilation failure and cardiovascular compromise Study designMulticenter retrospective cohort study of preterm infants who were ≤2 kg at the time of percutaneous PDA closure between August 2018 and July 2021. Indices of cardiorespiratory stability were collected pre-closure, immediately post-closure, and subsequently averaged every 4 hours for the first 24 hours post-procedure. The primary outcome was incidence of post-transcatheter cardiorespiratory syndrome: composite of: (i) hemodynamic instability (defined by systemic hypotension, systemic hypertension, or use of new inotropes/vasopressors in the first 24 hours after catheterization and at least one of the following: (i)ventilation failure or (ii) oxygenation failure. ResultsA total of 197 patients were included with a median [IQR] age and weight at catheterization of 34 [25, 43] days and 1090 [900, 1367] grams, respectively. The primary composite outcome was reported in 46 (23.3%) patients and subcomponents of oxygenation and/or ventilation failure, systolic hypotension or systolic hypertension were noted in 81 (41.1%), 3 (1.5%) and 86 (43.6%) respectively. Logistic regression models showed weight at catheterization and respiratory severity score pre-closure to be significantly associated with post-transcatheter cardiorespiratory syndrome. ConclusionPost-transcatheter cardiorespiratory syndrome is characterized primarily by systemic hypertension and oxygenation failure, with a very low incidence of hypotension and need for inotropes.

Transcatheter patent ductus arteriosus closure in premature infants requiring high-frequency ventilation.

Transcatheter closure has become a common treatment method for patent ductus arteriosus in premature infants at many centres; however, many remain uncertain about the ability to perform the procedure in the catheterisation laboratory for infants requiring high-frequency ventilation. This study presents our centre's experience following the implementation of neonatal ventilatory guidelines, which resulted in 100% procedural success without any procedural or respiratory adverse events.

Double Intervention in a Patient with Large Patent Ductus Arteriosus (PDA) and Moderate Upper Muscular Ventricular Septal Defect (VSD) with Bidirectional Shunt with Severe Pulmonary Hypertension

Patent ductus arteriosus (PDA) and Ventricular septal defect (VSD) are commonly encountered problems and constitute about 40% of all congenital heart lesions. The association of these two conditions in a single patient is not very uncommon. Both these conditions can be treated by placing intracardiac devices. Double interventional closure of Patent Ductus Arteriosus (PDA) and Ventricular Septal Defect (VSD) was performed in a gravely ill infant at her 3 months and 5 months of age respectively, who was suffering from recurrent pneumonia and heart failure since birth. These were lifesaving procedure for that patient which led to writing this report.

Venous-Only Transcatheter Closure: A Safe and Effective Strategy for Patent Ductus Arteriosus

Objectives: This study aimed to assess the feasibility and effectiveness of transcatheter device closure of patent ductus arteriosus (PDA) exclusively through an isolated venous route. Methodology: A retrospective descriptive study was conducted at the Rawalpindi Institute of Cardiology. Patient data from 2019 to 2023 undergoing PDA closure using transcatheter devices were analyzed. PDA diagnosis was established via echocardiography, and the procedure was performed solely through a venous line under fluoroscopy, omitting the traditional method of using both arterial and venous lines. Results: A total of 212 patients underwent transcatheter PDA closure through a venous-only route, with ages ranging from 6 months to 14 years. The mean weight was 10.07 kg (range: 5 kg to 27 kg, SD 4.43). The average procedure time was 30 ± 10.3 minutes (range: 15.0 to 65 minutes), and fluoroscopy time was 5.4 ± 3.18 minutes (range: 2.1 to 19 minutes). Immediate closure was achieved in all patients, with no residual leaks or device embolization observed. Additionally, there were no reported complications such as arrhythmia, vascular access issues, or significant blood loss. No cases of aortic or pulmonary stenosis were identified, and no deaths occurred. All patients were discharged within 48 hours post-procedure. Conclusion: Transcatheter closure of PDA exclusively through the venous route, without the use of an arterial line, demonstrates itself as an effective and safe method for PDA closure.

Evaluation of the reduction of radiation dose received by pediatric patients in new-generation biplane angiocardiography: Randomized controlled study

ObjectiveWe aimed to evaluate the safety and efficacy of radiation dose reduction with a new-generation biplane angiocardiography system in patients undergoing transcatheter isolated patent ductus arteriosus (PDA) closure. Materials and methodsFifty pediatric patients who underwent transcatheter PDA closure were randomly divided into two groups as normal radiation dose and low dose. Patients who required additional procedures other than PDA closure were excluded. PDA closure was performed according to the angiographic measurement of the defect. After the procedure, age, weight, sex, PDA measurements, and radiation measurements such as dose-area product (DAP, Gy.cm2) and air kerma (AK, mGy) were compared between the groups. ResultsThere was no statistically significant difference between the groups in age, sex, weight, PDA diameter, PDA type, device used, and device diameter (p > 0.05). While there was no statistically significant difference between the groups in terms of cine recording, number of recorded images, and fluoroscopy time (p > 0.05), there was a statistically significant difference between the total DAP, cine and fluoroscopy DAP, total AK, frontal and lateral tube AK, and DAP/kg (mGy.m2/kg) measurements (p < 0.05). ConclusionTranscatheter PDA closure with a low radiation dose is as effective as that with a normal radiation dose. The radiation dose received by the patient during the procedure was significantly reduced. With the vision provided by this study, it seems possible to work with a low radiation dose in other groups of patients.

Lung ultrasound score in the decision of patent ductus arteriosus closure in neonates.

We aimed to investigate the role of lung ultrasound (LUS) score in the closure of hemodynamically insignificant patent ductus arteriosus (PDA) and the clinical findings of the patients before and after closure. The study groups (107 preterm neonates under 34 gestational weeks) were classified as hemodynamically significant PDA (group 1), hemodynamically insignificant PDA with closure therapy (group 2), hemodynamically insignificant PDA without closure therapy (group 3), and no PDA group (group 4) based on the echocardiography. 6- and 10-region LUS scores were compared for each group. There was a significant difference between groups 1 and 3 on first, third, and seventh days. In contrast, groups 1 and 2 had similar LUS scores on the first, third, and seventh days. There was a negative correlation between LUS scores on the first and third days and gestational age, birth weight, the first- and fifth-minute APGAR scores, and there was a positive correlation between aortic root to left atrium ratio, and PDA diameter/weight ratio. We observed that LUS scores in patients with hemodynamically insignificant PDA treated with closure therapy were similar to in patients with hemodynamically significant PDA. Thus, LUS score can have role in PDA closure in preterm neonates. However, more comprehensive studies are needed.

Post-ligation cardiac syndrome after surgical versus transcatheter closure of patent ductus arteriosus in low body weight premature infants: a multicenter retrospective cohort study.

Transcatheter patent ductus arteriosus (PDA) closure is a safe and effective alternative to surgical ligation in low-body-weight infants. Post-ligation cardiac syndrome (PLCS) is defined as severe hemodynamic and respiratory collapse within 24h of PDA closure, requiring initiation or an increase of an inotropic agent by > 20% of preligation dosing and an absolute increase of at least 20% in ventilation parameters compared with the preoperative value. Whilst PLCS is routinely observed after surgery, its incidence remains poorly described following transcatheter closure. This study aimed to compare the incidence of PLCS after surgical versus transcatheter closure of PDA in low-body-weight premature infants. Propensity scores were used to compare surgical (N = 78) and transcatheter (N = 76) groups of preterm infants who underwent PDA closure at a procedural weight less than 2000g in two tertiary institutions between 2009 and 2021. The primary outcome was the incidence of PLCS. Secondary outcomes included overall mortality before discharge, risk factors for PLCS, and post-procedural complications. Procedural success was 100% in both groups. After matching, transcatheter group experienced no PLCS vs 15% in the surgical group (p = 0.012). Furthermore, overall mortality (2% vs 17%; p = 0.03) and major complications (2% vs 23%; p = 0.002) were higher in the surgical group. Surgery (100% vs 47%; p < 0.01), gestation age (25 ± 1 vs 26 ± 2weeks, p < 0.05) and inotropic support before closure (90% vs 29%; p < 0.001) were associated with PLCS occurrence. Conclusion: Transcatheter PDA closure may be equally effective but safer than surgical PDA closure in low-body-weight premature infants. What is Known: • Post-ligation cardiac syndrome is a serious and common complication of surgical closure of the ductus arteriosus in preterm infants. • Transcatheter closure of preterm ductus arteriosus is a safe and effective technique that is becoming more and more common worldwide. What is New: • Device closure is safer than surgical ligation for patent ductus arteriosus closure in preterm infants and may be the first-line non-pharmacological therapeutic option in this indication in experienced teams. • Our findings should encourage neonatologists and pediatric cardiologists to start and/or strengthen a durable interventional program for transcatheter PDA closure in premature infants.

Percutaneous closure of patent ductus arteriosus versus surgical treatment in low-birth-weight preterms: a systematic review and meta-analysis.

The optimal management of a patent ductus arteriosus in a population of preterm infants is controversial. Traditionally, when the patent ductus arteriosus does not close either with conservative treatment or in response to pharmacological therapy, the only option is surgical closure. However, transcatheter occlusion might provide a therapeutic alternative. We searched PubMed, Embase, and Cochrane databases for non-randomised and randomised controlled trials that compared transcatheter percutaneous closure of patent ductus arteriosus with surgical ligation in low-birth-weight preterm infants (<2,500 g). A random-effects model was used for outcomes with high heterogeneity. We included twelve studies comprising 4,668 low-birth-weight preterm infants, of whom 966 (20.7%) were in the transcatheter percutaneous closure group, and 3,702 (79.3%) patients were included in the surgical group. All-cause mortality (OR0.28; 95% confidence interval 0.18-0.423; p < 0.00001; I2 = 0%) and haemodynamic instability (OR 0.10; 95% confidence interval 0.05-0.21; p < 0.001; I2 = 14%) were significantly lower in the transcatheter percutaneous closure group. There was no significant difference between transcatheter and surgical patent ductus arteriosus closure for the outcomes of bronchopulmonary dysplasia (0.93; 95% confidence interval 0.46-1.87; p = 0.83; I2 = 0%) and major complications (OR 0.76; 95% confidence interval 0.34-1.69; p = 0.51; I2 = 43%). These findings suggest that transcatheter patent ductus arteriosus closure in preterm infants under 2,500 g is a safe and effective alternative to surgical treatment. There was a substantial reduction in all-cause mortality and haemodynamic instability with transcatheter intervention compared to surgical closure.

Case Report of Type II Cardio- Cerebral Syndrome: Acute Ischemic Stroke followed by Acute Inferior Myocardial Infarction

We report a case of a preterm infant who underwent transcatheter closure of patent ductus arteriosus (PDA) with Amplatzer Piccolo device through the left femoral vein. During the procedure, a partially occluded inferior vena cava (IVC) with significant collateralization was noted. The catheter was negotiated using a coronary guide wire and the infant tolerated the procedure well. Interestingly, the infant had a normal IVC in prior radiological films. The cause of this acquired occluded IVC remained obscure.

Clinical Value of Echocardiographic Screening and Dynamic Observations for Ductus Arteriosus Closure in Newborns

Objective: To explore and analyze the clinical value of echocardiography screening and dynamic observation for ductus arteriosus closure in newborns. Methods: The study was conducted from August 2022 to December 2023. 500 newborns who were admitted to our hospital were selected as research subjects for this study (Kunming Tongren Hospital). All subjects underwent echocardiography to determine the severity of patent ductus arteriosus (PDA). The inner diameter of the pulmonary artery was measured, and the pulmonary artery pressure was estimated through tricuspid regurgitation. If the patient had high pulmonary artery pressure, elective closure surgery was performed. Results: Among the 500 subjects, 448 cases of ductus arteriosus closure and 52 cases of PDA were detected by echocardiography, including 23 cases of simple PDA, 15 cases with patent foramen ovale, 11 cases with atrial septal defect, 1 case with muscular ventricular septal defect, 1 case with tricuspid valve prolapse, and 1 case with tricuspid valve chordae tendineae rupture. After symptomatic treatment and intervention, their echocardiogram results were reviewed and no abnormalities were found. All measurement results of children with PDA combined with pulmonary hypertension were better than before treatment (P &lt; 0.05). Conclusion: Echocardiography is a fast, accurate, and reliable non-invasive imaging examination technology. It can significantly improve congenital heart disease detection rate in infants and young children. Early intervention based on the examination results can dramatically improve the quality of life of infants and young children with PDA.

Correlation between the Closure Time of Patent Ductus Arteriosus in Preterm Infants and Long-Term Neurodevelopmental Outcome.

In patent ductus arteriosus (PDA) in preterm infants, the relationship between treatment timing and long-term developmental prognosis remains unclear. The purpose of this study was to clarify the relationship between the age in days when ductus arteriosus closure occurred and long-term development. Preterm infants with a birth weight of less than 1500 g who were admitted to our NICU over a period of 9 years (2011-2019) and were diagnosed with PDA were included. A new version of the K-type developmental test for corrected ages of 1.5 and 3 years was used as an index of development. The relationship between the duration of PDA and the developmental index was evaluated using Pearson's correlation coefficient, and multiple regression analysis was performed. Development quotient (DQ) at the ages of 1.5 and 3 years showed a correlation with the PDA closure date and the standard deviation (SD) value of the term birth weight. Multiple regression analysis showed a positive correlation of the DQ at 1.5 and 3 years with the SD value of the term birth weight and a negative correlation with the PDA closure date. In addition, a stronger correlation was found in the "posture/motor" sub-item at 3 years. On the other hand, the analysis including preterm infants without PDA showed that preterm infants with PDA closure on the 6th day or later after birth had a significantly lower 3-year-old DQ than preterm infants with a PDA exposure within 5 days. In conclusion, it is suggested that the decrease in cerebral blood flow due to PDA in preterm infants has an adverse effect on long-term neurodevelopment. Appropriate interventions, including surgical treatment for PDA in preterm infants without delay, ideally within 5 days of birth, may be effective in improving the developmental prognosis.

Renal function after ductus arteriosus transcatheter closure with or without angiography in very preterm infants.

Transcatheter closure of the patent ductus arteriosus (TCPDA) is increasingly used in preterm infants as an alternative to surgical ligation. However, clinically ill preterm infants are at risk of contrast nephropathy due to the angiography contrast agents used during the procedure. We performed a single-centre before-and-after comparative study in VLBW infants to compare the kinetics of serum creatinine during the first 4 days after TCPDA with or without angiography. 69 patients were included and divided into two groups: TCPDA with (contrast+; n = 37) and without (contrast-, n = 32) use of contrast agent. The median dose [range] of contrast agent was 1.0 mL/kg [0.6-2.4 mL/kg]. The change in serum creatinine level between day 2 to 4 after TCPCA and baseline decreased in the contrast- group (-17% [-46%; 18%]), while it increased in the contrast+ group (7% [-24%; 202%] p = 0.002). Comparison of blood urea levels between groups showed similar significant differences. The change in serum creatinine between day 2 to 4 and baseline was significantly correlated with the dose of contrast agent (r2 = 0.682; p < 0.001). The use of contrast agents during TCPDA can potentially harm the renal function of very preterm infants. Therefore, we advise minimising or avoiding the use of contrast agents.

German Registry for Cardiac Operations and Interventions in Congenital Heart Disease: Annual Report 2022.

The German Registry for Cardiac Operations and Interventions in Patients with Congenital Heart Disease is a voluntary registry initiated by the German Society for Thoracic and Cardiovascular Surgery and the German Society for Pediatric Cardiology and Congenital Heart Defects. Since 2012, the registry collects data for the assessment of treatment and outcomes of surgical and interventional procedures in patients with congenital heart disease (CHD) of all age groups. This real-world, prospective all-comers registry collects clinical and procedural characteristics, adverse events (AEs), mortality, and medium-term outcomes (up to 90 days) of patients undergoing surgical and interventional. A unique pseudonymous personal identifier (PID) allows longitudinal data acquisition in case of further invasive treatment in any participating German heart center. Prior to evaluation, all data sets are monitored for data completeness and integrity. Evaluation includes risk stratification of interventional and surgical procedures and classification of AEs. Each year's data are summarized in annual reports containing detailed information on the entire cohort, all subgroups, and 15 index procedures. In addition, each participating center receives an institutional benchmark report for comparison with the national results. This paper presents a comprehensive summary of the annual report 2021. In 2021, a total of 5,439 patients were included by 22 participating centers. In total, 3,721 surgical, 3,413 interventional, and 34 hybrid procedures were performed during 6,122 hospital stays. 2,220 cases (36.3%) could be allocated to the 15 index procedures. The mean unadjusted in-hospital mortality ranged from 0.4% among interventional and 2% among surgical cases up to 6.2 % in cases with multiple procedures. In-hospital mortality among index procedures accounted for 2.3% in total cavopulmonary connection, 20.3% in Norwood procedures, and 0.4% following interventional closure of patent ductus arteriosus. For the remaining seven surgical and five interventional index procedures, no in-hospital deaths were recorded. The 10-year longitudinal evaluation of 1,795 patients after tetralogy of Fallot repair revealed repeat interventional or surgical procedures in 21% of the patients. Over the same period, 31.1% of 2,037 patients, following initial treatment of native coarctation, required at least one additional hospital admission, 39.4% after initial interventional, and 21.3% after initial surgical therapy. The annual report 2021 of the German Registry for Cardiac Operations and Interventions in CHD shows continuously good results in accordance with previous data of the registry. Compared to international registries on CHD, it can be ascertained that in Germany invasive treatment of CHD is offered on a high medical level with excellent quality. The proven fact that patients with various malformations like tetralogy of Fallot and coarctation of the aorta require repeat procedures during follow-up confirms the urgent requirement for longitudinal assessment of all patients presenting with complex lesions.

Передчасно закрита артеріальна протока: можливі ризики для новонародженого

Premature closure of the fetal ductus arteriosus is a rare phenomenon that results in increased right ventricular pressure, leading to the development of isolated right ventricular hypertrophy, high pulmonary hypertension, and even death. Purpose - to present a rare clinical case of prenatally closed ductus arteriosus in a newborn boy, that clinically manifested by severe respiratory failure immediately after birth. Clinical case. The child was admitted to the neonatal intensive care unit 5 hours after delivery with clinical signs of severe respiratory failure, child was oxygen-dependent. It is known from the anamnesis that the child was delivered by urgent cesarean section on the basis of a prenatally diagnosed prematurely closed arterial duct. A week before the delivery, the mother had an acute respiratory viral infection accompanied by high fever, which was treated with high doses of over-the-counter ibuprofen. The 2D echocardiography showed severe hypertrophy of the right ventricular wall and tricuspid insufficiency, which was caused by premature closure of the ductus arteriosus. The flow through the ductus arteriosus was not determined. Aortic coarctation as a possible cause of right ventricular hypertrophy in the newborn period was excluded. The infant was switched to constant positive pressure artificial ventilation (CPAP) to reduce pulmonary vascular resistance and afterload of the right ventricle. Over the next 3-4 weeks of oxygen therapy, the child's general condition improved significantly. Hypertrophy of the right ventricular wall regressed to normal size, the child grows and develops according to age. Conclusions. Premature prenatal closure of the arterial duct can be idiopathic or caused drugs intake that suppress prostaglandin production late in the pregnancy. Pregnant women should be counseled about the potential side effects on the fetus caused by the use of NSAIDs, especially in the third trimester of pregnancy. Urgent delivery and oxygen therapy contribute to the regression of intracardiac changes and significantly improve general condition of the child. The study was conducted in accordance with the principles of the Declaration of Helsinki. The informed consent of the child’s parents was obtained for the study. No conflict of interests was declared by the authors.

Arch watch: current approaches and opportunities for improvement.

Coarctation of the aorta (CoA) is a ductus arteriosus (DA)-dependent form of congenital heart disease (CHD) characterized by narrowing in the region of the aortic isthmus. CoA is a challenging diagnosis to make prenatally and is the critical cardiac lesion most likely to go undetected on the pulse oximetry-based newborn critical CHD screen. When undetected CoA causes obstruction to blood flow, life-threatening cardiovascular collapse may result, with a high burden of morbidity and mortality. Hemodynamic monitoring practices during DA closure (known as an "arch watch") vary across institutions and existing tools are often insensitive to developing arch obstruction. Novel measures of tissue oxygenation and oxygen deprivation may improve sensitivity and specificity for identifying evolving hemodynamic compromise in the newborn with CoA. We explore the benefits and limitations of existing and new tools to monitor the physiological changes of the aorta as the DA closes in infants at risk of CoA.
