Serial Changes in Right Ventricular Outflow Tract Gradient and Endocarditis Risk After Transcatheter Pulmonary Valve Replacement.

ABSTRACT:

Background

Infective endocarditis (IE) after transcatheter pulmonary valve replacement (TPVR) remains a significant concern. Although there are overall good short-term and long-term hemodynamic outcomes, limited data exist comparing postimplantation echocardiographic findings leading to IE.

Objectives

To compare the progressive echocardiographic performance of percutaneous implanted pulmonary valves before the development of IE.

Methods

This is a single-center retrospective cohort study of all patients who underwent successful TPVR using either Medtronic Melody or Edwards Sapien valves from 2009 to 2021. Patient demographics, procedural details, and yearly echocardiographic findings were collected and compared as appropriate. The risk of IE was compared between groups
