Abstract: OBJECTIVE: To assess the safety and benefits of new techniques and technologies such as single-dose (del Nido) cardioplegia and suture fasteners (COR-KNOT) in patients undergoing mini-thoracotomy for degenerative mitral valve repair (MVR). METHODS: From 2009 to 2016, 252 patients underwent primary isolated degenerative MVR by mini-thoracotomy by a single surgeon. Del Nido cardioplegia was used in 153 patients (61%) and COR-KNOT in 168 (67%). Patient outcomes were compared using propensity-matching separately for del Nido versus Buckberg cardioplegia and COR-KNOT versus knot-pusher. RESULTS: There were no operative deaths and 99.2% of the patients had none/trivial mitral regurgitation at discharge. In patients receiving del Nido or Buckberg cardioplegia, occurrence of adverse events was similar. However, aortic cross clamp (AoCC; 54.2 ± 15.7 vs 64 ± 15.8 min; P < 0.0001) and operative room (OR; 308 ± 42.1 vs 336 ± 63 min; P < 0.001) times were shorter with del Nido cardioplegia. In patients receiving COR-KNOT versus knot-pusher, occurrence of adverse events was similar. However, AoCC (54.1 ± 15.2 vs 66.1 ± 15.9 min; P < 0.0001) and OR (311 ± 43.6 vs 336 ± 65.4 min; P < 0.0001) times were shorter with COR-KNOT. Results were similar after matching for both, del Nido versus Buckberg cardioplegia and COR-KNOT versus knot-pusher. CONCLUSION: New techniques and technologies, such as del Nido cardioplegia and COR-KNOT, decrease AoCC and OR times without compromising patient safety.
