Surgical intervention for post-infarct ventricular septal defect (VSD) is a challenging procedure due to patients’ complex preoperative conditions. While percutaneous VSD closure can be considered as an alternative surgical repair, complete of the remains difficult and associated with various procedural complications. We report rare case patient postoperative residual shunts who experienced rec...

Forty percent of people with Down syndrome exhibit heart defects, most often an atrioventricular septal defect (AVSD) and less frequently a ventricular septal defect (VSD) or atrial septal defect (ASD). Lymphoblastoid cell lines (LCLs) were established from lymphocytes of individuals with trisomy 21, the chromosomal abnormality causing Down syndrome. Gene expression profiles generated from DNA ...

Large-conductance, voltage-, and Ca²⁺-dependent K⁺ (BK) channels are broadly expressed in various tissues to modulate neuronal activity, smooth muscle contraction, and secretion. BK channel activation depends on the interactions among the voltage sensing domain (VSD), the cytosolic domain (CTD), and the pore gate domain (PGD) of the Slo1 α-subunit, and is further regulated by accessory β subuni...

BACKGROUND To evaluate the surgical and medical efficacy of the patients operated for Ventricular Septal Defect (VSD) with Pulmonary Hypertension and Pulmonary Vascular Resistance (PVR). Infants and children with elevated PVR and Pulmonary Hypertension are associated with significant mortality and morbidity after surgical closure. Circulatory assist devices and sophisticated medicines may not b...

INTRODUCTION The myocardial performance index (MPI) has been described as a non-invasive Doppler measurement of ventricular function. The aim of this study was to assess MPI following surgical correction of ventricular septal defect (VSD) and to evaluate its impact on postoperative recovery. MATERIAL AND METHODS This is a prospective study involving 30 children (16 girls and 14 boys) operated...

BACKGROUND AND PURPOSE The recent increase in the prevalence of ventricular septal defect (VSD) has been ascribed to the improved detection of small defects with echocardiography and the wider use of screening. The aim of this study was to determine the prevalence and timing of spontaneous closure of specific types of VSD in neonates using echocardiographic screening and follow-up. METHODS Tw...

OBJECTIVE The term non-committed was used to define hearts in which the VSD was anatomically related to, or was close to, neither great vessel, being separated from both by considerable muscle. We report our experience of the surgical management of this subset, considered being of particular surgical relevance. METHODS Between January 1987 and December 1997, 23 patients having double-outlet r...

BACKGROUND Three quarters of patients with 22q11.2 Deletion Syndrome (22q11.2DS) have congenital heart disease (CHD), typically conotruncal heart defects. Although it is currently common practice to test all children with typical CHD for 22q11.2DS, many adult patients have not been tested in the past and therefore 22q11.2DS might be under-recognised in adults. OBJECTIVES To determine the prev...

This study was designed to explore whether it was possible to evaluate the severity of VSD, PDA, and ASD by measuring brain natriuretic peptide (BNP) levels. We also investigated normal BNP levels in children to provide a baseline for our study. We measured BNP levels in 253 normal children, including 11 normal neonates, and in 91 VSD patients, 29 PDA patients, and 34 ASD patients. BNP levels s...

Background—Ventricular septal defect (VSD) complicating acute myocardial infarction has been studied primarily in small, prethrombolytic-era trials. Our goal was to determine clinical predictors and angiographic and clinical outcomes of this complication in the thrombolytic era. Methods and Results—We compared enrollment characteristics, angiographic patterns, and outcomes (30-day and 1-year mo...
