Abstract

The Engager aortic bioprosthesis consists of bovine pericardial leaflets mounted on a self-expandable frame with unique anatomic orientation capabilities to engage the aortic valve cusps. We report the initial North American transcatheter aortic valve implantation (TAVI) experience with the Engager device. Transapical TAVI was performed in 4 patients (mean age 80 ± 6 years, Society of Thoracic Surgeons score 5 ± 1%). The valve was anatomically oriented and successfully implanted in all patients. There were no conversions to open operation or major procedure-related adverse events. Pacemaker implantation was necessary in 1 patient. None of the patients showed paravalvular leak. The Engager device for TAVI provides anatomic orientation and anchoring that prevents coronary obstruction and paravalvular leak.
