Neonatal Critical Valvar Aortic Stenosis

Balloon aortic valvotomy (BAV) is an alternative to surgical valvotomy in infants and children. We compared BAV in 16 consecutive neonates (1985-1988) to surgical valvotomy in a prior group of 16 consecutive neonates (1978-1984). Both groups were comparable in terms of age, weight, hemodynamic data, left ventricular size, and associated lesions. There were six early and one late deaths after su...

Valvar aortic stenosis with unusual features.

This case report documents the co-existence of valvar aortic stenosis and hypertrophic obstructive cardiomyopathy with systemic hypertension and calcific mitral annulus, a combination which has not hitherto been reported. It is the purpose of this paper to help assess the true incidence of the co-existence of aortic stenosis and hypertrophic cardiomyopathy.

Percutaneous aortic valvoplasty in congenital aortic valvar stenosis.

OBJECTIVE To evaluate immediate and midterm results with percutaneous aortic valvoplasty. MATERIAL AND METHODS We reviewed the records of 141 patients undergoing percutaneous aortic valvopasty over a period of 13 years. RESULTS The patients were aged from 2 months to 40 years, with a mean of 10.9 +/- 9.9 years. Of the total, 90 (63+/%) were male. The initial systolic peak-to-peak gradient d...

Serial hemodynamic observations in asymptomatic children with valvar aortic stenosis.

The natural history of valvar aortic stenosis in children is uncertain. This report analyzes serial clinical and catheterization data of nine initially asymptomatic children. The first hemodynamic study was performed at an average age of 6.8 years, and the follow-up study at an average age of 13.1 years. Cardiac indices and left ventricular enddiastolic pressures were consistently normal in all...
