Balloon-expandable valve vs. self-expandable valve for small aortic annuli: a GRADE-assessed systematic review and updated meta-analysis

In patients with SAA undergoing TAVR, BEV and SEV yield comparable rates of PPM and permanent pacemaker implantation. However, BEV may be associated with a higher risk of moderate or greater paravalvular leak. Valve selection should be individualized, considering patient anatomy and device-specific characteristics to optimize outcomes.
