The Lifetech KONAR-MF ventricular septal defect occluder (MFO) is increasingly used for transcatheter perimembranous (pmVSD) closure. We aim to collect real-world data on patient outcomes and MFO performance in pmVSD cases. This was a nonrandomized, retrospective, multicenter, postmarketing clinical follow-up study of patients implanted with the device between 2018 2023. primary endpoint 6-month composite success, defined as technical success (successful implantation retention at end...

ABSTRACT Background Multisystem inflammatory syndrome in children (MIS‐C) is associated with cardiac involvement 67%–80% of cases. Cardiac symptoms often normalize rapidly after treatment, but few studies are available on the long‐term effects. Methods Our study evaluated functions 40 patients diagnosed MIS‐C between August 2021 and November 2022. Conventional echocardiography (ECHO), electrocardiography (ECG), speckle tracking (STE), MR were performed at time diagnosis 3‐nd 6‐month...

Introduction Device closure of perimembranous ventricular septal defects (pmVSD) is a successful off-label treatment alternative. We aim to report and compare the outcomes pmVSD in children weighing less than 10 kg using Amplatzer Duct Occluder II (ADOII) Konar-MF VSD (MFO) devices. Methods Retrospective clinical data review 52 with hemodynamically significant pmVSD, sent for transcatheter ADOII MFO, between January 2018 2023. Baseline, procedural, follow-up were compared according implanted...

Inflammatory myofibroblastic tumor (IMT) is a rare soft tissue of the heart. In literature, cardiac IMT often described as an endocardial-based cavitary mass originating from right side heart in infants and adolescents. this article, we present 5-year-old boy with who had no complaints was diagnosed murmur during his routine examination. Transthoracic echocardiography showed homogeneous polypoid pulmonary valve, extending into main artery systole causing obstruction ventricular outflow...

Abstract Purpose Fetal growth restriction (FGR) is a common pregnancy complication that can be associated with several adverse perinatal outcomes. One of these negative outcomes ductus arteriosus, especially in preterm babies. In this study, intrauterine heart function and diameter were evaluated babies FGR. Methods Thirty‐seven fetuses FGR compared 37 normal‐weight at the same gestational week. our ventricular diameters, aorta, pulmonary artery, arteriosus (DA), aortic arch diameter, flow...

INTRODUCTION: Evidence shows that rather than postnatal diagnoses, prenatal diagnoses of congenital heart diseases are correlated with better long-term results and lower mortality rates. In this retrospective study, neonatal stage infants isolated cardiac anomalies, their indications for operation or intervention (if any), the rates in first age attempted to be demonstrated.

Levoatrial cardinal vein (LACV) is anomalous connection between the left atrium or pulmonary veins and any systemic which derived from venous system. Presence of levoatrial without a cardiac anomaly very rare congenital return. In literature, no LACV was found in two siblings who were asymptomatic did not have an additional anomaly. Therefore, we present cases ( ) symptoms, diagnosis (the echocardiographic finding, computed tomography (CT) aniographic images treatment modalities isolated vein.
