Transthoracic Doppler echocardiography of normal tricuspid valve prostheses: comparison between surgical and transcatheter approaches.

ABSTRACT:

Background

Tricuspid valve (TV) replacement with surgical bioprosthetic, surgical mechanical, or transcatheter prostheses is a critical intervention for severe tricuspid regurgitation or stenosis. However, comprehensive echocardiographic comparisons of hemodynamic performance across these prosthesis types remain limited, especially for novel transcatheter prostheses. This study aimed to systematically analyze the transthoracic echocardiographic (TTE) Doppler parameters of three types of tricuspid prostheses with normal function to provide accurate references for the management of patients following clinical TV replacement (TVR).

Methods

This retrospective study included 62 patients with surgical bioprosthetic valves, 52 with surgical mechanical valves, and 25 with transcathe
