Abstract
Background: Balloon aortic valvuloplasty (BAV) is increasingly used in the TAVR era, and radial access is now feasible. We investigate the comparative effectiveness of compliant and non-compliant balloons for BAV Methods 253 Patients undergoing BAV at a tertiary center in USA from 2021-2024 were evaluated. Changes in peak gradient and aortic insufficiency, adoption of radial access, and number of balloon inflation; periprocedural VARC-III vascular and bleeding events, and nonaccess events including heart block, stroke, hypotension, severe AI and periprocedural death; and 30-day composite of death, heart failure hospitalization, stroke, and discharge failure was assessed. Chi-square test, Wilcoxon ranksum test, and Kaplan Meier estimates with logrank test were used for dichotomous variables, non-parametric continuous variables, and time-to-event, respectively Results Compliant and non-compliant balloons were used in 58.1 and 41.9% of cases, respectively. There was no significant difference in drop in gradient, increase in AI, number of balloon inflation. (A-B). Radial access use was more common with compliant balloons, 53.6% vs 27.2%(p<0.001) (B). Periprocedural and 30-day event rates were similar (all p>0.05) with numerically more non-access events with noncompliant balloons (C-D) Conclusion In the contemporary era, BAV with noncompliant and compliant balloons have similar hemodynamic and clinical outcomes and a higher adoption rate of radial access with compliant balloons [Formula presented]
