CT assessment of right heart anatomy across tricuspid regurgitation severity grades: implications for transcatheter interventions.

ABSTRACT:

Purpose

A five-grade severity scheme has been introduced for echocardiographic grading of tricuspid regurgitation (TR). Although higher TR grades have been associated with worse prognosis, it is unknown whether they can help determining patient eligibility for transcatheter tricuspid valve interventions (TTVI) and correspond to different anatomical phenotypes. The aim of our study was to investigate the relationship between TR severity and tricuspid valve (TV) anatomy and determine the screening failure rate for TTVI.

Methods

The anatomy of TV, right heart and venae cavae in patients with significant TR having undergone cardiac CT scan, was investigated using 3-mensio software and correlated with TR severity determined by echocardiography.

Results

One hundred patients
