Thirty-five consecutive patients with ventricular septal defect (VSD) associated with aortic insufficiency (AI) who underwent corrective surgery are presented. There were seven operative and three late deaths among the patients operated upon before 1968. No death, however, was encountered among the most recent 18 consecutive patients. The VSD was closed directly in 14 patients and with a Teflon...

Children with ventricular septal defect (VSD) often demonstrate failure to thrive (FTT). Such patients usually have reduced systemic cardiac output which has been postulated as a cause for their growth retardation. This study was conducted to ascertain the mechanism of the reduced cardiac output in children with VSD and FTT and also in a porcine model of VSD. Forward stroke volume was reduced i...

Ventricular septal defect (VSD) is the most common form of congenital heart diseases. Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases involved in causal cardiac tissue remodeling. We studied the changes of circulating MMP-2 and MMP-9 activities in the patients with VSD severity and closure. There were 96 children with perimembranous VSD enrolled in this study. We ...

Left-to-right (L-R) shunting across a ventricular septal defect (VSD) often involves a direct VSD-pulmonary arterial component (jet) that surges from the VSD immediately into the pulmonary artery. We used the thermodilution technique in dogs with acute experimental VSD to quantify this component. In dogs with supracristal VSD (n = 7), the direct component represented 76 +/- 4% (mean +/- SE) of ...

BACKGROUND Ventricular septal defect (VSD) is the most prevalent type of congenital heart disease and is a major cause of substantial morbidity and mortality in infants. Accumulating evidence implicates genetic defects, especially in cardiac transcription factors, in the pathogenesis of VSD. However, VSD is genetically heterogeneous and the genetic determinants for VSD in most patients remain t...

Ventricular septal defect (VSD) is one of the common congenital heart malformations. Several factors lead to the development of VSD, including familial causes, exposure to certain drugs, infectious agents, and maternal metabolic disturbances. We considered that induced pluripotent stem (iPS) cells derived from VSD patients can be used to study the origin and pathogenesis of the VSD. Here, we sh...

We report a patient with a significant residual left-to-right shunt who underwent surgical repair for traumatic VSD. This 13-year-old boy was stabbed with a pair of scissors through his heart. After initial life-saving surgery with lacerated left ventricular wall repair and VSD closure, residual VSD was noted. Six months later, we performed a successful transcatheter closure of the residual VSD...

OBJECTIVE To analyze the outcome of continuous versus interrupted closure technique of ventricular septal defect (VSD) closure in Tetrology of Fallot with reference to postoperative residual VSD after total correction. METHODS A randomised control study was conducted between January 2008 to December 2008 at The Department of Cardiac Surgery, National Institute of Cardiovascular Diseases (NICV...
