Abstract

Off pump implantation of artificial chordae to correct mitral regurgitation – early results ORAL PRESENTATION Open Access Off pump implantation of artificial chordae to correct mitral regurgitation – early results K Rucinskas1*, V Janusausakas1, D Zakarkaite1, S Aidietiene1, R Samalavicius1, G Speziali2, A Aidietis1 From 23rd World Congress of the World Society of Cardio-Thoracic Surgeons Split, Croatia. 12-15 September 2013 Background New technologies for mitral valve repair are emerging. One of them is NeoChord DS1000 system (Neochord, Inc., Minneapolis, MN). This device is designed to deliver artificial chordae tendinae to mitral valve leaflets on a beating heart through left ventricle wall. This is our initial experience with this device. Methods This data is part of multi-center, nonrandomized, prospec- tive 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 pos- terior 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. Results Median duration of operation was 110 min (80 to 150 min). Less than second degree mitral regurgitation in six months was achieved in 11 (85%) patients. 1 (8%) patient has developed recurrent third degree mitral regurgitation in one month. 1 (8%) patient has been converted to con- ventional mitral valve repair during procedure. There were no other adverse events related to the procedure. Conclusions Treatment of mitral regurgitation by off-pump implanta- tion of artificial chordae using NeoChord device is feasi- ble and s
