The study evaluated a balloon expandable transcatheter heart valve system in an ovine banding model. The results showed that the valve system had good functionality and biocompatibility.
The aim of the study was to evaluate a balloon expandable transcatheter heart valve (THV) system (Myval) at 6-month follow-up in ovine banding model. Eleven THV systems were implanted via carotid approach. There were 2 procedure-related deaths and 2 premature deaths. At 6 months all valves that completed follow-up (n = 7) were functional, with no significant regurgitation, calcification, thrombi, or vegetation. Mean pressure gradient was 21.9 ?? 11 mm Hg, maximum velocity = 3.3 ?? 1 m/s, and ejection fraction was 53.3 ?? 6%. Myval THV showed optimal hemodynamic performance and biocompatibility.
