Paravalvular Regurgitation after TAVI
Paravalvular regurgitation after transcatheter aortic valve implantation occurs in in over 50% of patients, and correlates with 1-year mortality. The regurgitant jets are best characterized with transesophageal echocardiography to define the circumferential extent and cross-sectional area. Overtime, most the regurgitation decreases, and occasionally disappears completely.
