Abstract:
Percutaneous balloon valvuloplasty (PBV) was done in 7 adults of pulmonary valvular stenosis, which was diagnosed with catheterization and cine-angiography of rigtht heart, in Seoul National University Hospital from Jan. 1986 to Dec. 1986. The results were as follows : 1) Among the seven cases six were male and the range of age was from 19 to 40 years. Atrial septal defects associated in 2 cases were not significant clinically. 2) The peak systolic gradient from right ventricle to pulmonary artery before the procedure was below 50 mmhg in 1 cases, 50 to 100 mmHg in 1 case, and above 100 mmHg in 5 cases. 3) Before PBV the mean systolic pressure of right ventricle was 121+/-42 mmHg and the peak systolic gradient was 106+/-41 mmHg. After PBV those were 58+/-30 mmHg and 40+/-31 mmHg, revealing significant improvement. 4) Balloon catheter (Medi-tech, 9F) was used in all cases. single balloon of 20 mm outer diameter was applied in 2 cases and double balloons of various sizes were applied in 5 cases in which single balloon showed inadequate dilatation. It is suggested that percutaneous balloon valvuloplasty is safe and effective alternative to surgical valvotomy of pulmonary valvular stenosis in adults.
