Aims: Long-term data on the durability of currently available transcatheter heart valves are limited.

For the purposes of this study, we included only those patients undergoing successful TAVI with the CoreValve prosthesis who had a minimum followup of four years (n=125).

Abstract

Aims: Long-term data on the durability of currently available transcatheter heart valves are limited. We sought to assess four-year clinical and echocardiographic outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) with the CoreValve prosthesis. Methods and results: Between June 2007 and February 2014, 450 consecutive patients with symptomatic severe aortic stenosis underwent TAVI in our institution. For the purposes of this study, we included only those patients undergoing successful TAVI with the CoreValve prosthesis who had a minimum followup of four years (n=125). Survival rates at one, two, three and four years were 83.2, 76.8, 73.6 and 66.3%, respectively. Aortic regurgitation was a common finding after the procedure, especially due to paravalvular regurgitation (PVR), which was observed in the majority of patients (71.5%), mostly mild (52.0%). Progression from mild acute PVR to moderate PVR at four-year follow-up was reported in three patients. No case...
