Notes:
Between July 1985 and July 1987, 18 consecutive adult patients with congenital pulmonary stenosis underwent pulmonary balloon valvuloplasty (PBV). There were 11 males and 7 females, aged 15–45 years (mean 25). A double balloon technique was used in 14 patients and a single balloon in four. The size of the balloon used was 0.9 to 1.4 times the size of the pulmonary annulus. Eleven patients were restudied by repeat cardiac catheterization 6 months later. Student's t-test was used for comparison of data. Right ventricular (R V) systolic pressure before dilatation ranged from 84 to 180 (mean 123 ± 28.3) mmHg and the right ventricular to pulmonary artery (PA) peak systolic gradient ranged from 60 to 165 (mean 105 ± 30.2) mmHg. Immediately after dilatation, the RVsystolic pressure dropped to 30–80 (mean 53 ± 14.2) mmHg (P 〈 0.001). RV to PA peak systolic gradient dropped to 10–57 (mean 32 ± 14.2) mmHg (P 〈 0.001). A restudy of 11 patients 6 months later showed a further drop of RV systolic pressure to 35–65 (mean 49 ± 11.3) mmHg (P 〈 0.05). RV to PA peak systolic gradient continued to drop to 10–48 (mean 26 ± 11.3) mmHg (P 〈 0.01). Cardiac index improved from 2.68 ± 0.73 to 3.03 ± 0.40 L/min/m2, P 〈 0.05. No complication was noted apart from either sinus bradycardia or extrasystole in a few patients. It was noted that balloon to annulus ratios of 1.1 to 1.4 produced sustained relief of the pulmonary valve stenosis. We concluded that PBV is the treatment of choice for congenital pulmonary stenosis. It reduced the hospital stay to 2 days and avoids the ri±k of open heart surgery. (J Interven Cardiol 1988:1:1)
