Résumé
Minimally invasive techniques of mitral valve (MV) repair have been increasingly used in recent years. Transapical implantation of artificial chordae on a beating heart under 2D/3D transesophageal echocardiographic guidance with the NeoChord DS1000 device is a new surgical treatment of degenerative mitral regurgitation (MR). To evaluate early results of MV repair with the NeoChord DS1000 device in the first group of consecutive patients operated on in Poland. Twenty-one patients with severe MR due to posterior leaflet prolapse (81% male; mean age: 60.7 ±12.7 years) underwent MV repair with the NeoChord DS1000 system. There were 12 (57.1%) patients with type A (an isolated central prolapse/flail), 8 (38.1%) patients with type B (multisegment disease/flail) and 1 (4.8%) patient with type C (posterior/paracommisural area) MV prolapse. A flail leaflet was present in 12 (57.1%) patients. The median number of neochords was 3 (2-6). We assessed by echocardiography left-sided heart morphology and evaluated MR degree before and 6 months after chords implantation. Early procedural success was achieved in 100% of patients. At the 6-month follow-up nonsignificant MR (trace and mild) was detected in 17 (81.0%) patients, while moderate MR was detected in 4 (19.0%) patients; mean values of left-sided heart dimensions and volumes, mitral E and E' velocity of lateral MV annulus significantly decreased. A novel procedure with the NeoChord DS1000 device is feasible in properly selected patients, and results in a significant reduction of MR degree and left ventricle and left atrium reverse remodeling at the 6-month follow-up.
