ABSTRACT

OBJECTIVES - To define the incidence of high residual gradient (HRG) after transcatheter aortic valve replacement (TAVR) in BAVs and their impact on short term outcome and 1-year mortality.


BACKGROUND - Transcatheter heart valves (THVs) offer good performance in tricuspid aortic valves with low rate of HRG. However, data regarding their performance in bicuspid aortic valves (BAV) are still lacking.


METHODS - The BEAT (Balloon vs Self-Expandable valve for the treatment of bicuspid Aortic valve sTenosis) registry included 353 consecutive patients who underwent TAVR (Evolut R/PRO or Sapien 3 valves) in BAV between June 2013 and October 2018. The primary endpoint was device unsuccess with post-procedural HRG (mean gradient20 mmHg). The secondary endpoint was to identify the predictors of HRG following the procedure.


RESULTS - Twenty patients (5.6%) showed HRG after TAVR. Patients with HRG presented higher body mass index (BMI) (30.7 ± 9.3 vs. 25.9 ± 4.8; p < 0.0001) and higher baseline aortic mean gradients (57.6 ± 13.4 mmHg vs. 47.7 ± 16.6, p = 0.013) and more often presented with BAV of Sievers type 0 than patients without HRG. At multivariate analysis, BMI [odds ratio (OR) 1.12; 95% confidence interval (CI) 1.051.20, p = 0.001] and BAV type 0 (OR 11.31, 95% CI 3.4537.06, p < 0.0001) were confirmed as independent predictors of high gradient.


CONCLUSION - HRG following TAVR in BAVs is not negligible and is higher among patients with high BMI and with BAV 0 anatomy.
