Extremely Small 20-mm Versus Standard-Size Balloon-Expandable Transcatheter Heart Valves: Propensity-Matched Analysis From the OCEAN-TAVI Registry.

ABSTRACT:

Background

The 20-mm balloon-expandable transcatheter heart valve (THV) represents the smallest available option for transcatheter aortic valve replacement (TAVR). Its current underutilization stems from concerns regarding prosthesis-patient mismatch, durability, and potential adverse outcomes.

Objectives

The purpose of this study was to compare the long-term outcomes between the 20-mm balloon-expandable THVs and standard-size balloon-expandable THVs.

Methods

Patients who underwent transfemoral TAVR with SAPIEN THVs were sourced from the OCEAN-TAVI (Optimized Transcatheter Valvular Intervention) registry, an ongoing, multicenter cohort study that has enrolled over 7,000 TAVR patients in Japan. A 1:3 propensity-matched analysis, based on 24 baseline clinical and echoca
