ABSTRACT
OBJECTIVE:
To report short and midtem follow-up results of balloon aortic valvuloplasty to treat congenital aortic stenosis.METHODS:
Seventy-five patients (median age 8 years) underwent the procedure through the retrograde femoral or carotid route.RESULTS:
The procedure was completed in 74 patients (98.6 percent). The peak-to-peak systolic gradient dropped from 79.6±27.7 to 22.3±17.8 mmHg (P<0.001), the left ventricular systolic pressure dropped from 164±39.1 to 110±24.8 mmHg (P<0.001), and the left ventricular end diastolic pressure dropped from 13.3±5.5 to 8.5±8.3 mmHg (P< 0.01). Four patients (5.3 percent) died due to the procedure. Aortic regurgitation (AoR) appeared or worsened in 27/71 (38 percent) patients, and no immediate surgical intervention was required. A mean follow-up of 50±38 months was obtained in 37 patients. Restenosis and significant AoR were observed in 16.6 percent of the patients. The estimates for being restenosis-free and for having significant AoR in 90 months were 60 percent and 50 percent, respectively.CONCLUSION:
Aortic valvuloplasty was considered the initial palliative method of choice in managing congenital aortic stenosis, with satisfactory short- and midtermresults:
