[Percutaneous pulmonary valvuloplasty in 135 patients].
We present our 7 years experience with 135 pts aged 1.4-44 years (mean 10-yrs) in whom percutaneous balloon valvuloplasty (BPV) for congenital pulmonary stenosis was attempted. In 4 pts we failed to place the balloon at valvar level, in another four BPV was repeated so, 135 procedures in 131 pts were performed. Balloon diameter/pulmonary anulus diameter ratio (BD/PD) ranged from 0.9 to 1.85 (mean 1.37). In 10 cases double balloon technique was used. Immediate results: in the whole group of 131 pts the right ventricular-pulmonary artery gradient (RV-PAG) was reduced from 74 +/- 42 to 34 +/- 34 mm Hg, and right ventricular systolic pressure (RVSP) decreased from 92 +/- 41 to 54 +/- 34 mm Hg just after BPV. 86 pts (65.6%)--group I, had good immediate result of BPV (RVSP less than 50 mm Hg). 4 of them had dysplastic pulmonary valves (DPVs). RV-PAG in 82 pts with normal valves decreased from 53 +/- 25 to 15 +/- 7 mm Hg right after BPV. In 45 pts (34.4%)--group II, immediate result of valvuloplasty was recognised as unsatisfactory (RVSP greater than or equal to 50 mm Hg): in 4 of them BD/PD was smaller or equal 1.2 (subgroup IIa); 34 others had significant subpulmonary obstruction (SPO) that appeared or increased after BPV (subgroup IIb); and in remaining 7, DPVs were noticed (subgroup II c).(ABSTRACT TRUNCATED AT 250 WORDS)
