OBJECTIVE To evaluate the effect of percutaneous closure of patent ductus arteriosus (PDA) on left ventricular (LV) systolic and diastolic function in children. BACKGROUND Limited studies are available on alteration in LV hemodynamics, especially diastolic function, after PDA closure. METHODS Thirty-two consecutive children with isolated PDA treated by(More)
This report evaluated whether acute phase reactants can predict the development of mitral regurgitation following percutaneous mitral valvotomy. 58 patients who developed significant mitral regurgitation following valvotomy were retrospectively compared with 58 age, sex and procedure technique matched control patients, who had valvotomy without mitral(More)
We conclude that balloon valvotomy of the mitral valve with the Inoue technique is a safe and effective procedure for treating juvenile rheumatic MS. The almost complete absence of iatrogenic atrial septal defect and the low incidence of significant mitral regurgitation is noteworthy.
Echocardiography in a 4-year-old boy, with nephroblastoma of the left kidney, revealed a large homogenous mass in right atrium extending from inferior vena cava, and protruding through tricuspid valve into right ventricle during diastole. Ultrasonography revealed the contiguous spread of the tumor through renal vein with near total caval occlusion. The(More)
A rare aneurysm of a congenital coronary arteriovenous fistula is reported. Echocardiography showed a dilated left coronary and left circumflex artery with normal left anterior descending artery. A dilated structure near the crux was confirmed to be a large aneurysm of circumflex coronary artery on selective angiography. It drained into the posterior right(More)
BACKGROUND There is a paucity of data regarding the long-term outcome of patients operated for ventricular septal defect with severe pulmonary arterial hypertension and elevated pulmonary vascular resistance. METHODS AND RESULTS We evaluated the long-term follow-up results of a selected cohort of patients with nonrestrictive ventricular septal defect and(More)
