The study is made to describe the efficacy and safety of balloon postdilatation (BPD) for the treatment of residual aortic regurgitation (RAoR) after transcatheter aortic valve implantation (TAVI).
Methods and Results
A single-center observational study is made with 157 consecutive patients accepted to TAVI. The patients were divided into two groups (no BPD-period and BPD-period). Before BPD, RAoR ≥ 2 was seen in 25% of the patients in group 1 and in 29% of the patients in group 2 (P ≥ 0.593). BPD was carried out in 95% (n = 21) of the patients in group 2 with RAoR ≥ 2. Regurgitation improved one grade in 68% of the cases (n = 15), 2 grades in 14% (n = 3), and remained without change in 18% (n = 4). RAoR < 2 was achieved in 91% (n = 73) of the patients in group 2 versus 75% (n = 58) in group 1 (RR = 0.35, 95% CI 0.16–0.80, P = 0.013). We recorded no aortic ring ruptures, damage to the device or displacements. Slight central regurgitation not present before BPD was registered in one case.
BPD offers a very good safety profile and reduces RAoR in a large percentage of cases. BPD should be considered for the treatment of moderate to severe RAoR following TAVI. © 2013 Wiley Periodicals, Inc.
