Retrospective analysis of single-center early and midterm results of transapical catheter-based mitral paravalvular leak closure with a purpose-specific device.

Introduction: Due to the recent lack of definitions to establish the severity of paravalvular leak (PVL) and endpoints for its treatment, the effectiveness and safety of a new device for PVL closure have not been comprehensively analyzed.

Aim: To analyze a single center's experience of mitral PVL closure in a surgical transapical catheter-based fashion with a purpose-specific device.

Material And Methods: This is a retrospective cohort study of patients following transapical catheter-based mitral PVL closure with a purpose-specific device.
