Loop Neochord Versus Leaflet Resection Techniques for Minimally Invasive Mitral Valve Repair: Long-Term Results

The study compared long-term results of loop neochord replacement with leaflet resection techniques in 2134 patients undergoing minimally invasive mitral valve repair.
They demonstrated a significant reduction in early mitral regurgitation with the loop technique (on echocardiographyl; p=0.003) when compared with leaflet resection. Additionally, the long-term outcomes were excellent compared with classical leaflet resection techniques (the 1-, 5- and 10-year survival rates were 98 ± 1%, 95 ± 1% and 86 ± 2% for the loop technique versus 97 ± 1%, 92 ± 1% and 81 ± 2% for resection patients, respectively (P = 0.003).
