Real-time monitoring and step-by-step guidance for transcatheter tricuspid annuloplasty using transesophageal echocardiography

Abstract

Tricuspid regurgitation (TR) interventions are under rapid development. The K-Clip™ system is the first domestic transcatheter tricuspid annuloplasty system with unique clamping procedure to achieve annular reduction. Intraoperative echocardiographic monitoring procedures for transcatheter tricuspid annuloplasty have not been reported yet in China. Thus, this review aimed to propose the standard two-dimensional and three-dimensional transesophageal echocardiographic workplanes and procedures to guide and monitor the implantation of K-Clip system based on our experience in Zhongshan Hospital, Fudan University to provide a reference point for the intraoperative echocardiographic monitoring of future transcatheter tricuspid annuloplasty devices in China.
