BACKGROUND Transcatheter closure of coronary artery fistulas has emerged as a successful alternative to surgery. We describe various techniques and short-term findings in 15 patients who were taken up for transcatheter closure of these fistulas. METHODS AND RESULTS Fifteen patients (aged 2-55 years; 12 males) with coronary artery fistulas underwent(More)
Transcatheter closure of congenital ventricular septal defect (VSD) using various devices is gaining acceptance in selected cases of perimembranous and muscular defects, avoiding the inherent risks of cardiopulmonary bypass. The procedure was attempted in 137 patients having congenital defects using Rashkind Umbrella Device (RUD) in 29 patients, Amplatzer(More)
OBJECTIVE We hypothesized that mitral annular velocities would improve immediately after relief of mitral stenosis and that serial assessment could be used as an index for quantifying functional changes after percutaneous mitral commissurotomy (PMC). METHODS Longitudinal left ventricular annular velocities were quantified by spectral pulsed wave Doppler(More)
Left ventricle to right atrial communications, collectively known as Gerbode defects, are usually congenital defects and surgical closure remains the treatment of choice. We report a rare case of Gerbode defect acquired following surgical closure of a ventricular septal defect. The defect was successfully closed percutaneously with an Amplatzer ventricular(More)
BACKGROUND Phosphodiesterase-5 inhibitors produce a significant decrease in pulmonary vascular resistance in patients with idiopathic pulmonary arterial hypertension. We studied the effects of tadalafil, a phosphodiesterase-5 inhibitor, on short-term hemodynamics, tolerability, and efficacy over a 12-week period in patients of Eisenmenger syndrome having a(More)
Percutaneous transcatheter closure of ruptured sinus of valsalva aneurysm was attempted in eight patients between January 1995 and March 2003 as an alternative strategy to surgery as this technique at present is an accepted therapeutic modality for various intracardiac defects. The age range was 14-35 years, all were male, seven in symptomatic class III and(More)
The success with occlusion devices for the closure of atrial septal defects and patent ductus arteriosus prompted the transcatheter closure of single and multiple muscular ventricular septal defects (VSD). The procedure for VSD was first attempted by Lock et al. in 1988 and devices originally designed for the closure of other intracardiac defects (Rashkind(More)
Rupture of an iliac artery during percutaneous transluminal coronary angioplasty is a rare but potentially devastating complication. We report a case of iatrogenic external iliac artery rupture that was successfully treated by temporary balloon occlusion followed by endovascular stent graft placement in an unusual manner. Limited availability of the(More)
BACKGROUND AND AIM OF STUDY Systemic thromboembolism is a major complication in patients of mitral stenosis (MS) with atrial fibrillation (AF) due to induction of hypercoagulable state. The aim was to assess the relationship, if any, between control of ventricular rate and systemic coagulation factors. METHOD 70 patients of moderate to severe MS in AF(More)
