Multicenter Experience for Early and Mid-Term Outcome of MyVal Transcatheter Pulmonary Valve Implantation.

Transcatheter pulmonary valve implantation (TPVI) is a surgical alternative for correcting dysfunctional right ventricular outflow tract in previously operated patients. MyVal transcatheter heart valve (THV) (Meril Life Sciences, India), a new transcatheter valve designed for aortic position has recently been reported to be implanted in pulmonary position. Myval transcatheter valve were implanted in patients with stenosed dysfunctional conduits, severe regurgitation from transannular patch or dysfunctional surgical pulmonary valves (Bioprosthesis).

Neonatal Outcomes of Critical Congenital Heart Defects: A Multicenter Epidemiological Study of Turkish Neonatal Society : Neonatal Outcomes of CCHD.

Critical congenital heart disease (CCHD) is one of the leading causes of neonatal and infant mortality. We aimed to elucidate the epidemiology, spectrum, and outcome of neonatal CCHD in Türkiye. This was a multicenter epidemiological study of neonates with CCHD conducted from October 2021 to November 2022 at national tertiary health centers.

Giant pulmonary pseudoaneurysm following balloon dilatation of the pulmonary artery to relieve pulmonary band.

Pulmonary artery pseudoaneurysms are uncommon. They may occur secondary to trauma, infectious diseases, vasculitis syndromes, neoplasms, congenital diseases, and pulmonary hypertension. Due to increasing number of cardiac interventions, iatrogenic complications are among the major causes of pulmonary artery pseudoaneurysms.

Experiences of Two Centers in Percutaneous Ventricular Septal Defect Closure Using Konar Multifunctional Occluder.

Background: Transcatheter closure of perimembraneous ventricular septal defect still poses a challenge due to the adjacent structures of the tricuspid and aortic valves and the risk of atrioventricular block. We report our experience at 2 centers using the KONAR-MF (multifunctional occluder) ventricular septal defect device, which gained its CE mark in May 2018.

Methods: A retrospective study was carried out on all patients who underwent transcatheter ventricular septal defect closure with the KONAR-MF (multifunctional occluder) ventricular septal defect device at 2 centers.

Percutaneous Closure of Atrial Septal Defects with the MemoPart Atrial Septal Occluder: The Early-Term Results of a Multicenter Study.

Atrial septal defect (ASD) is a common congenital heart disease with left-to-right shunt that may lead to pulmonary hypertension over time. Secundum ASD closure with transcatheter technique is currently the preferred method. The aim of this study was to evaluate the clinical experience and early-term outcomes of patients treated with a MemoPart ASD occluder device between June 2013 and June 2019.

The Use of Chronic Total Occlusion (CTO) Wires for Perforation of Atretic Pulmonary Valve; Two Centers Experience.

Pulmonary valve atresia with intact ventricular septum (PA-IVS) can be treated either surgically or transcatheterly for eligible patients. Perforation of pulmonary valves using chronic total occlusion (CTO) guidewires has been reported as an alternative to radiofrequency (RF) perforation. We sought to report our experience with CTO guidewires for perforation of atretic pulmonary valves and subsequent balloon dilatation (with or without patent ductus arteriosus stenting) in patients with PA-IVS from two centers.

Transcatheter closure of the aortopulmonary window in a three-month-old infant with a symmetric membranous ventricular septal defect occluder device.

Although most of aortopulmonary window cases are closed surgically, percutaneous closure can be also used in suitable patients. Defects which are far from the pulmonary and aortic valves, coronary artery, and pulmonary artery bifurcation, with adequate septal rims are considered suitable for percutaneous closure. A three-month-old male infant weighing 4 kg was referred to our pediatric cardiology department with the complaints of fatigue while breastfeeding, difficulty in weight gain, heart murmur, and respiratory distress.

Current Strategies for the Management of Anomalous Origin of Coronary Arteries from the Pulmonary Artery.

Introduction: The coronary arteries, which have to originate from the aorta, may sometimes rise from the pulmonary artery. This study evaluated clinical and diagnostic findings, treatment methods, and follow up of cases with anomalous coronary arteries arising from the pulmonary artery.

Patients And Methods: Eight patients with the diagnosis of anomalous left coronary artery from the pulmonary artery (ALCAPA) (N = 6) and anomalous right coronary artery from the pulmonary artery (ARCAPA) (N = 2), between January 2014 and January 2020 from a single center university hospital, were included in the study.

Left subclavian artery originating from left pulmonary artery in DiGeorge syndrome.

Left subclavian artery originating from the left pulmonary artery is a rare aortic arch anomaly. Herein, we, for the first time in Turkey, present a case of left subclavian artery originating from the left pulmonary artery via ductus arteriosus in DiGeorge syndrome and causing subclavian steal syndrome.

Right ventricular outflow tract stenting during neonatal and infancy periods: A multi-center, retrospective study.

Background: The aim of this study was to evaluate the outcomes of right ventricular outflow tract stenting for palliation during the newborn and infancy periods.

Methods: Between January 2013 and January 2018, a total of 38 patients (20 males, 18 females; median age 51 days; range, 3 days to 9 months) who underwent transcatheter right ventricular outflow tract stenting in three centers were retrospectively analyzed. Demographic characteristics, cardiac pathologies, angiographic procedural, and clinical follow-up data of the patients were recorded.

Off-pump ascending aorta or aortic arch to descending aorta bypass with a pericardial roll for the treatment of critically ill infants with interrupted aortic arch.

Aim: Standard surgical treatment of the interrupted aortic arch with the use of cardiopulmonary bypass is risky especially in critically ill babies. In this manuscript, we present the results of off-pump pericardial roll bypass for the treatment of aortic interruption.

Material And Methods: The technique was applied in nine critically ill infants between July 2011 and December 2019.

Congenital cardiac interventions during the peak phase of COVID-19 pandemics in the country in a pandemics hospital in Istanbul.

Introduction: In this report, we aim to present our algorithm and results of patients with congenital cardiac disorders who underwent surgical or interventional procedures during the peak phase of the pandemics in our country.

Patients And Methods: The first COVID-19 case was diagnosed in Turkey on 11 March, 2020, and the peak phase seemed to end by the end of April.

Background And Objectives: This study aims to compare the characteristics, effectiveness and results of transcatheter closure of atrial septal defect between children, adolescents, and adults.

Subjects And Methods: In this study, 683 patients who underwent atrial septal defect closure in the last 10 years were divided into three groups: children (age <12), adolescents (age 12 to 16), and adults (age >16) as group 1, group 2 and group 3, respectively.

Results: The average defect size and incidence of complex atrial septal defect were higher in group 3 (p=0.

A rare coronary anomaly with masked diagnosis: Anomalous left circumflex artery from right pulmonary artery.

Anomalous origin of the circumflex coronary artery from the pulmonary artery is a rare congenital coronary anomaly. While it generally follows an asymptomatic course, if undiagnosed it may lead to severe clinical outcomes, including sudden death. The condition can be masked by associated defects, so when it is clinically suspected, diagnosis must be confirmed by conventional and/or magnetic resonance angiography, even if echocardiography clearly shows coronary roots.

Cardiac Interventions in Pregnant Patients without Fluoroscopy.

Introduction: Cardiac interventions with fluoroscopy during pregnancy carry significant risks for the fetus. This report reviews three pregnant patients: two of them requiring pacemaker implantation and one underwent diagnostic cardiac catheterization without fluoroscopy.

Methods: The cases were performed using EnSite system (St.

Efficacy of very low-dose prostaglandin E1 in duct-dependent congenital heart disease.

Aim: The present study aims to define the lowest effective prostaglandin E1 dose in patients with inadequacy of pulmonary blood flow and/or intracardiac blood mixing and those with inadequate systemic blood flow.

Methods: Patients with inadequacy of both pulmonary blood flow and/or blood mixing (Group 1) and those with inadequate systemic blood flow (Group 2) were retrospectively evaluated in two separate groups with regard to the prostaglandin E1 starting dose given in the referring facility, the lowest and the highest dose administered in our centre, treatment duration, adverse effects, and administered treatment.

Results: No difference between the groups could be detected with respect to sex or birth weight (p=0.
