Simple technique of repair for Barlow syndrome with posterior resection and chordal transfer via minimally invasive approach: primary experience in a consecutive series of 22 patients

摘要: Current techniques for mitral valve repair (MVR) in Barlow’s disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes has been developed. Between 2009 2013, 22 patients underwent minimally invasive MVR severe regurgitation (MR). simple, was applied, including resection P2 segment posterior leaflet (PML) with preservation shortest chordae, transfer preserved chordae A2, implantation semi-rigid open ring. In 2015, all were contacted follow-up by transthoracic echocardiography (TTE) interviewed their clinical status. During (mean 2.8 ± 1.1 years; 100% complete), one patient died abdominal bleeding 4 months after initial calcification PML replacement recurrence MR. Among remaining cohort 3.0 ± 1.0 years), NYHA class I, II III present 13, 6, 1, respectively. TTE demonstrated MR grade 0, 1+, or 2+ 40, 55, 5%, respectively, mean maximum transvalvular gradients ranging at 1.9 ± 1.7 4.7 ± 3.3 mmHg, facilitates presence Barlow’s, simultaneously addressing height position anterior leaflet. This proven durable mid-term our small series warrants further validation larger cohorts.
