Association between computed tomography-derived tricuspid annular dimensions and prognosis: insights from whole-beat computed tomography assessment.

ABSTRACT:

Aims

Tricuspid regurgitation (TR) has been associated with outcome in patients treated with transcatheter aortic valve implantation (TAVI). Tricuspid annulus (TA) dimensions are associated with TR. However, the TA is highly dynamic during the cardiac cycle, and the interaction between the TA dimensions, TR, and patient prognosis has never been evaluated. This study aimed to characterize the dynamics of the TA along with the cardiac cycle and its association with prognosis in patients undergoing TAVI.

Methods and results

Patients with severe aortic stenosis who underwent whole-beat computed tomography (n = 393, mean age 80 ± 7 years, 53% male) were included. The ratio between anterior-posterior (AP) and septal-lateral (SL) diameter of the TA was calculated at end-systole (ES)
