Background

The use of balloon aortic valvuloplasty (BAV) has resurged since the development of transcatheter aortic valve replacement (TAVR). The aim of our study was to determine the procedural and long-term outcomes of patients treated by BAV in the early TAVR era.

Methods

From 2005 to 2008, 323 consecutive patients presenting with severe aortic stenosis were treated by BAV in our institution.

Results

Mean age and logistic EuroSCORE were 80.5 卤 9.9 years and 28.7% 卤 12.5%, respectively. The effective orifice area increased from 0.68 卤 0.25 to 1.12 卤 0.39 cm2 (P < .001) after BAV. Inhospital major complications occurred in 22 patients (6.8%), with a mortality rate of 2.5%. Eighty-five patients (26.3%) were bridged to surgical aortic valve replacement (SAVR, 9.6%) or TAVR (16.7%). Twenty-eight patients (8.7%) had at least 1 repeat BAV. Two hundred ten patients (65%) received only medical therapy post-BAV. Mean duration of follow-up was 20.7 卤 20.0 months. Kaplan-Meier analysis demonstrated that survival after single BAV was poor. Patients treated by BAV followed by SAVR or TAVR had the highest long-term survival rate (P < .001). Multivariable analysis revealed that logistic EuroSCORE, severe aortic regurgitation and stroke complications post-BAV, and medical therapy post-BAV were independent predictors of mortality.

Conclusions

The results of our study suggest that BAV is an acceptable bridge to SAVR or TAVR in a very high-risk population not immediately suitable for definitive therapy. Balloon aortic valvuloplasty remains only a brief temporizing procedure with a poor long-term outcome without subsequent definitive therapy.
