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.

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
