Does repeat balloon aortic valvuloplasty improve valve area in patients with aortic valve restenosis?
Does repeat balloon aortic valvuloplasty improve valve area in patients with aortic valve restenosis?
Repeat balloon aortic valvuloplasty for restenosis appears less efficacious than the initial procedure and is associated with high 6-month mortality.
Repeat BAV may be less effective for restenosis with high mortality; leaves open benefit in larger prospective studies.
Effective balloon aortic valvuloplasty (BAV) is limited restenosis. After aortic valve restenosis six patients underwent repeat BAV. In spite of the use of larger balloons there was a trend toward a less satisfactory result after repeat BAV (0.98 +/- .26 cm2 vs. 1.2 +/- .26 cm2), which did not reach statistical significance, P = .14. Mortality of the patients at 6 months was 50%. Repeat BAV may be less efficacious than the original procedure.
