Methods
A study cohort included 263 consecutive patients with symptomatic severe aortic stenosis (AS) who were subjected to ABV. Patients were stratified into three groups according to preprocedure degree of AR assessed by echocardiogram available before the procedure. Patients received postprocedure echocardiography and were followed for clinical events at 1 year.

Results
The study groups included pre-ABV with no AR=76 (29.9%), mild AR=180 (68.3%) and moderate AR=7 (2.7%). There were no differences in the baseline characteristics with a mean age of 81.9±9.4 and STS=12.9±9. At 1 year, the rate of death was 41.1% in patients with no AR, 46.9% in patients with mild AR and 63.6% in patients with moderate AR, respectively ( P =.31). The number of patients post-ABV with no AR decreased to 43 (16.3%) and increased in the mild AR to 206 (78.3%) and moderate AR to 14 (5.4%) ( P =.0009). The proportion of patients with no AR pre-ABV who developed mild AR post-ABV was 48.7%, and the proportion with mild AR pre-ABV who developed moderate AR post-ABV was 4.5% (all P <.001, Table 1 ). Two patients developed severe AR post-ABV.
