Off pump implantation of artificial chordae to correct mitral regurgitation – early results

چکیده
Methods This data is part of multi-center, nonrandomized, prospective Transapical Artificial Chordae Tendinae [TACT] trial. 13 patients with severe mitral regurgitation caused by isolated posterior mitral valve leaflet prolapse, were included in the study. The operation was done through left anterolateral thoracotomy on a beating heart. With TEE guidance, the NeoChord DS1000 was introduced into the left ventricle. The prolapsing segment was grasped with the device and ePTFE suture was attached to the posterior leaflet. Six patients received 2 ePTFE sutures to achieve competence of mitral valve, four patients 3 ePTFE sutures, and two patients 4 ePTFE sutures. At six months follow up all patients had TTE.

OBJECTIVES The goal of this study was to evaluate the safety and performance of the NeoChord DS1000 system (NeoChord, Inc., Minneapolis, Minnesota). BACKGROUND There is an increasing interest in transcatheter mitral valve (MV) treatment. The NeoChord DS 1000 system enables off-pump beating heart transapical MV repair with implantation of artificial neo-chordae. METHODS Patients with severe ...

Objectives: There are an increasing number of reports concerning mitral valve repair by reconstruction of the chordae tendinae with the use of expanded polytetrafluoroethylene (PTFE) sutures. However, little information is available about the extended application or results of this technique for extended prolapse of bilateral mitral leaflets, which is considered to be difficult to repair. Metho...

Mitral valve repair is considered the procedure of choice for correcting mitral regurgitation in myxomatous disease, providing long-term results that are superior to those with valve replacement. The use of artificial chordae to replace elongated or ruptured chordae responsible for mitral valve prolapse and severe mitral regurgitation has been the subject of extensive experimental work to defin...
