BACKGROUND A ventricular septal defect (VSD) is the most common form of congenital heart disease and is one of the most common cardiovascular anomalies in individuals with chromosome 22q11 deletion syndrome. However, the frequency of a chromosome 22q11 deletion in patients with a VSD is not known. In addition, among patients with a VSD, it is not clear whether particular types of VSD or associa...

The voltage-sensor domain (VSD) is a functional module that undergoes structural transitions in response to membrane potential changes and regulates its effectors, thereby playing a crucial role in amplifying and decoding membrane electrical signals. Ion-conductive pore and phosphoinositide phosphatase are the downstream effectors of voltage-gated channels and the voltage-sensing phosphatase, r...

The aim of this study was to examine if isolated fetal ventricular septal defect (VSD) is associated with trisomy 21. One hundred twenty six cases with prenatal VSD diagnosed by a pediatric cardiologist were reviewed. Cases with known risk factors for congenital heart disease, the presence of other major anomalies, soft signs for trisomy 21 or a positive screen test for trisomy 21 were excluded...

BACKGROUND Transcatheter balloon valvuloplasty has been the accepted first line treatment for congenital pulmonic stenosis (PS) in children. Transcatheter closure of perimembranous ventricular septal defect (VSD) with Amplatzer VSD occluder is an alternative to surgical repair. CASE PRESENTATION A 12 year old boy presented with history of exertional dyspnea and atypical chest pain. Physical f...

BACKGROUND Ventricular septal defects (VSD) are the most common subtype of congenital heart defects (CHD) and are estimated to account for 20 to 30% of all cases of CHD. The etiology of isolated VSD remains poorly understood. Eight core aminoacyl-tRNA synthetases (ARSs) (EPRS, MARS, QARS, RARS, IARS, LARS, KARS, and DARS) combine with three nonenzymatic components to form a complex known as the...

Value Sensitive Design (VSD) seeks to design technology that accounts for human values in a principled and comprehensive manner throughout the design process (Friedman, 1997). In this paper, we show how VSD can be seen as extending Alexander’s (1979) idea of a pattern to frame a larger research and design program on human values and information technology. We briefly present the theoretical con...

Material and methods: Between December 2004 and December 2013, 300 patients with medical record of VSD were admitted to our study, previously admitted to the cath lab at our center for percutaneous treatment of their VSD with various types of devices. All patients were followed until December 2013, 1 to 109 months. VSD type treated: perimembranous (VSDpm) 93.85 % and muscular (VSDM) 6.14%. The ...

A 77-year-old female patient underwent aortic valve replacement (AVR) with concomitant septal myectomy and tricuspid annuloplasty. Her symptoms did not improve after a successful operation. Echocardiogram demonstrated the presence of an iatrogenic ventricular septal defect (VSD). It was muscular in location and not the usual AVR with membraneous type of VSD, suggesting a complication from the m...

The aim of this study was to examine how somatic mutations of the GATA4 gene contributed to the genesis of ventricular septal defect (VSD). The coding and intron-exon boundary regions of GATA4 were sequenced of DNA samples from peripheral blood cells and cardiac tissues of twenty surgically treated probands with VSD. Seven novel heterozygous variants were detected in cardiac tissues from VSD pa...

AIMS Immediate surgical repair of ventricular septal defect (VSD) complicating acute myocardial infarction is associated with high mortality. Percutaneous device closure appears to be safe and effective in patients treated for a residual shunt after initial surgical closure, as well as in patients with a chronic post-infarct VSD. Primary transcatheter VSD closure in the acute setting may also o...
