An common complication following transcatheter aortic replacement is paravalvular regurgitation (PAR). Mild to moderate regurgitation occurs in over 50% of patients. The 1 year mortality of patients after TAVI correlate with the severity of the regurgitation.

TAVI Paravalvular Regurgitation Evolution

Aortic Valve Changes after TAVI

Transcatheter cardiac interventions are a fast evolving field. Aortic valve intervention is usually performed for aortic stenosis. Transcatheter aortic valve implantation (TAVI, TAVR) has shown to improve valve area from 0.7 cm2 to 1.7 cm2. This is associated wit
