during 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of shahid rajai heart hospital, tehran. all patients were subjected to cardiac catheterization and a angiocardiography. patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. seventy seven percent of childen were male. eight cases (61.5%) had williams&...
Survival of patients with severe congenital aortic stenosis beyond third decade is uncommon. This report describes a 31 year old patient who underwent successful aortoplasty and in addition septal myectomy for complete relief of left ventricular outflow obstruction.
Bicuspid aortic valve disease is the most common congenital heart defect, affecting 1% to 2% of the general population, with a higher prevalence in males (Hoffman & Kaplan, 2002; Movahed et al., 2006). Quite often, the diagnosis of bicuspid aortic valve disease is an incidental finding during an echocardiogram. However, the disease may be associated with significant valvular dysfunction and lea...
Congenital abnormalities of the aortic arch include interrupted aortic arch (IAA), coarctation of the aorta (CoA), and double aortic arch (DAA). Aortic arch repair is difficult and postoperative complications are common. However, postoperative tracheobronchial stenosis with respiratory insufficiency is an uncommon complication and is usually caused by increased aortic anastomotic tension. We re...
OBJECTIVES The aim of the study was to analyze the long-term results of congenital subvalvar aortic stenosis (SAS) relief and the risk factors associated with recurrence and reoperations. METHODS Between January 1960 and March 2005, 190 patients underwent surgical correction for discrete (n=140) and tunnel (n=50) congenital subaortic stenosis. There were 115 male and 75 female patients rangin...
We evaluated dilation technique (n=80) and aortic valve morphology by two-dimensional echocardiography (n = 58) in patients with congenital aortic valve stenosis to determine their influence on outcome. Patients' age (9 ± 9 years; range, 1 day-39 years) and a history of surgical valvotomy did not influence outcome. The number of dilating balloons (one vs. two) and balloon:annulus ratio based on...
Two cases of familial centronuclear myopathy are described. Both presented features of 'cardiomyopathy and one had signs of slight congenital aortic stenosis. The 'cardiomyopathy' was fatal in one case. The clinical histological, and necropsy findings are presented and discussed.
BACKGROUND Aortic valvuloplasty (AoVP) is an established procedure regarded as a valid alternative for surgical management of congenital aortic valve stenosis. However, its long-term efficacy in preventing or postponing aortic valve surgery remains uncertain for the individual patient. Therefore, the aim of this study was to study the long-term results of AoVP in pediatric patients and its effi...
Real-time, cross-sectional echocardiographic studies of the aortic valve were performed in 28 children with congenital valvular aortic stenosis and in 22 normal subjects. The presence of a stenotic valve was indicated by increase in echo production, abnormal motion pattern, and abnormal systolic position of the valve leaflets. Comparison of the maximum aortic cusp separation (MACS) to calculate...
