“…Our study confirms previous findings [4,6,[8][9][10][11][12]17,181 that infundibular obstruction occurring immediately after BPV is a dynamic process that regresses during the follow-up period (up to 2 years). In several of these former studies, patients were treated with betaadrenergic blockers after BPV [8,9,11,15]. Some investigators have even advocated the use of prophylactic beta-adrenergic blockers prior to BPV to reduce the incidence of infundibular obstruction [8].…”

Some investigators have even advocated the use of prophylactic beta-adrenergic blockers prior to BPV to reduce the incidence of infundibular obstruction [8]. In our study, all eight patients with follow-up catheterization were found to have substantial resolution of their infundibular gradients over a 17 month period without the use of betablockers.…”

“…Our limited experience with the new BPV technique suggests that it can be performed as successfully and safely as those reported by other investigators using fixed-size catheters (mainly Mansfield catheters) [8,9,14,161. Certain disparate aspects between the two BPV methods are worth noting.…”

“…Further studies will show whether or not the safety, efficacy, and long-term results of BPV using the Inoue balloon catheter are comparable to the conventional technique. [6,[8][9][10]12,15,18,24,25].…”

This report describes a new balloon pulmonary valvuloplasty technique using the Inoue balloon catheter performed in 14 consecutive adult patients, aged 17-47 years (mean 27). The mean right ventricular systolic pressure and the pulmonary valvular peak-to-peak systolic gradient decreased from 102 +/- 41 to 52 +/- 19 mm Hg (p = 0.001) and 81 +/- 40 to 7 +/- 7 mm Hg (p = 0.0002), respectively. An infundibular peak-to-peak systolic gradient either developed (n = 13) or increased (n = 1). None of the patients were treated with beta-adrenergic blockers before or after the valvuloplasty. Eight patients underwent repeat hemodynamic study 12-30 months (mean 17) after treatment, and had no evidence of valvular restenosis. The mean right ventricular systolic pressure and the mean infundibular peak-to-peak systolic gradient decreased, compared to the values immediately after valvuloplasty (54 to 40 mm Hg, p = 0.03, and 28 to 10 mm Hg, p = 0.03, respectively). The study suggests that pulmonary valvuloplasty in adults using the Inoue balloon catheter technique is feasible, safe, and effective.

“…22 However, although percutaneous balloon pulmonic valvuloplasty is widely performed in children with valvular stenosis, its value in adults has been less well defined. Several studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] showed the feasibility of the technique in adults, although neither the size of the series nor the length of follow-up was sufficient to permit definitive conclusions. Our study has shown that percutaneous pulmonic valvuloplasty with the Inoue balloon catheter is as effective in adults as it has been shown to be in children.…”
