The purpose of this study was to compare contemporary results of balloon dilatation and surgery for valvar aortic stenosis in infants and children in the five years between August 1988 and October 1993. Thirty four children underwent attempted balloon valvuloplasty (age 1 day-16 years, weight 1720 g-68 kg) (group 1), eight of whom were neonates with critical aortic stenosis. During the same per...

A growing list of transcatheter interventions is now available for treating patients with congenital and acquired heart disease. Among these procedures are creation of interatrial defects by balloon and blade septostomy , , balloon dilation of stenotic vessels and valves, and closure of unwanted intracardiac and extracardiac defects and vessels. This chapter focuses on several interventions: ba...

Preliminary reports have documented the utility of balloon aortic valvuloplasty as a palliative treatment for high-risk patients with critical aortic stenosis, but the effect of this procedure on cardiac performance has not been studied in detail. Accordingly, 32 patients (mean age 79 years) with long-standing, calcific aortic stenosis were treated at the time of cardiac catheterization with ba...

Of 120 consecutive balloon aortic valvuloplasty procedures for critical aortic stenosis, valvuloplasty was performed in combination with coronary angioplasty in nine patients (average age 76 years). All nine patients were symptomatic with angina and congestive heart failure before combined procedures. Aortic valvuloplasty was performed with 20 to 23 mm balloon catheters advanced retrogradely fr...

OBJECTIVE To evaluate 501 procedures of mitral balloon valvuloplasty and the differences among the group already submitted the prior surgical or balloon valvuloplasty, with 59 procedures and the group without previous intervention, with 442 procedures. METHODS It was used the single balloon in 403, Inoue balloon in 89 and a double balloon in six, with no difference between the 2 groups (p=0.6...

OBJECTIVES the aim of this study was to evaluate the long-term results of transcatheter balloon aortic valvuloplasty, the preferred treatment for congenital aortic stenosis (AS). BACKGROUND aortic valve function and reintervention late after this procedure are not well characterized. METHODS from 1985 to 2008, 563 patients underwent balloon dilation for congenital AS. After excluding those ...

BACKGROUND Aortic stenosis in the midgestation fetus with a normal-sized or dilated left ventricle predictably progresses to hypoplastic left heart syndrome when associated with certain physiological findings. Prenatal balloon aortic valvuloplasty may improve left heart growth and function, possibly preventing evolution to hypoplastic left heart syndrome. METHODS AND RESULTS Between March 200...
