Introduction Trans-apical beating heart off-pump mitral valve (MV) repair is a novel surgical technique for treating mitral regurgitation (MR) caused by degenerative flail/prolapse (DLP).
Aim To present early outcomes of a single-center experience with transapical beating heart mitral valve repair with the NeoChord system.
Material and methods Thirty-seven patients with severe symptomatic MR were treated with the NeoChord technique between September 2015 and December 2018 (78% men; mean age: 62.3 ±13.4 years). We evaluated standard cardiac surgery perioperative complications as well as those related to the NeoChord technique as well as early surgical success as defined by the reduction of MR to less than moderate by implantation of at least 2 neochordae.
Results During this series we had no hemodynamic instability due to bleeding or arrhythmia. There were no transapical technique-related adverse events such as a leaflet perforation or tear, a major native chord rupture, which would require implantation of a new chord, ventricular apex rupture, or left atrial perforation. There were no major adverse events including death, stroke or acute myocardial infarction. Nine (24%) patients developed an episode of perioperative atrial fibrillation. We were able to conclude the operation in 98% of our patients with less than moderate MR. One (2%) patient had moderate MR at the conclusion of the operation.
Conclusions Trans-apical off-pump MV repair with the NeoChord system is a safe, minimally invasive procedure, with few minor complications. In well-selected candidates it provides successful treatment of degenerative MR. Results are anatomy dependent, so preoperative patient selection is crucial.
