Initial experiences of transapical beating-heart mitral valve repair with a novel artificial chordal implantation device.

ABSTRACT:

Background

Severe mitral regurgitation (MR) is associated with progressive heart failure and impairment of survival. Degenerative MR accounts for most MV repair surgeries. Conventional mitral valve repair surgery requires cardiopulmonary bypass and is associated with significant morbidity and risks. Transapical beating-heart mitral valve repair by artificial chordae implantation with transesophageal echocardiography (TEE) guidance has the potential to significantly reduce surgical morbidity. We report the first-in-human experience of degenerative MR repair using a novel artificial chordae implantation device (Mitralstitch^TM system).

Methods

Ten patients with severe MR underwent transapical artificial chordae implantation using MitralstitchTM system. The procedure
