First Major Clinical Outcomes of Totally Endoscopic Robotic Mitral Valve Repair in Japan - A Single-Center Experience.
Circ J 2019; 83(8):1668-1673CJ

Abstract

BACKGROUND

In 2018, Japan became the first country to have robotic cardiac surgery covered under the national health insurance. The number of patients undergoing robotic mitral valve (MV) repair has been estimated to increase remarkably, but no reports in Japan have yet described the outcomes of robotic MV repair. This study aimed to analyze the early clinical outcomes of patients undergoing totally endoscopic robotic MV repair (TERMVR) as a landmark national study for this procedure.Methods and Results:A total of 213 patients (152 men; mean age, 55±11 years) underwent TERMVR during May 2014 to December 2018. Preoperative demographics, operative profiles, and postoperative outcomes, including follow-up echocardiography, were analyzed. Successful TERMVR was achieved in all patients. Operation, cardiopulmonary bypass, and aortic cross-clamp times were 192±49.8, 127±23.8, and 70.1±16.2 min, respectively. Intraoperative transfusion was performed in 20 patients (10%). There were no in-hospital deaths. All patients were alive during the median follow-up period of 255 days (interquartile range, 32.5-208 days). Freedom from recurrence of MR >grade 2+ was 97.3%, 95.0%, and 90.7% at 6, 12, and 24 months, respectively.

CONCLUSIONS

TERMVR is an effective and safe procedure with acceptable early postoperative outcomes.
