ABSTRACT
The authors report three cases of congenital pulmonary stenosis in adults over 50 years of age treated by percutaneous balloon valvuloplasty. Three symptomatic women aged 74, 80 and 51, had systolic pressure gradients ranging from 107 to 113 mmHg between the right ventricle and pulmonary artery. After valvuloplasty with two balloons or one trefoil balloon, the transvalvular pressure gradient fell to 25 to 30 mmHg. It was only 14 mmHg in one patient controlled after one year's follow-up. The cardiac index was initially decreased and did not change very much immediately after the procedure, increasing from 1.68 1/m2/mn to 1.77 1/m2/mn. The pulmonary valve surface area increased from 0.22 to 0.43 cm2. There were no complications and in one patient, reviewed two years later, the clinical improvement was maintained. Percutaneous valvuloplasty is indicated in severe and/or poorly tolerated pulmonary stenosis. With the 10 other previously reported cases of patients over 50 years of age, the procedure was successful in 12 out of 13 patients (92%). In these patients of 51 to 80 years of age, the systolic pressure gradient between the right ventricle and pulmonary artery was reduced from 112 +/- 46 mmHg to 43 +/- 26 mmHg (-62%). Slight pulmonary regurgitation appeared in 5 out of 9 cases. Valvuloplasty was usually well tolerated and there were no fatalities. There were no signs of restenosis in 5 cases controlled 10 days to 1 year after dilatation. In the future, systematic Doppler echocardiographic examinations should help comparison of cardiac haemodynamics before, immediately after valvuloplasty and at long-term.(ABSTRACT TRUNCATED AT 250 WORDS)
