To the best of our knowledge, there is no nationwide data available on the development of minimally invasive cardiac surgery (MICS) in China. The purpose of this study was to report the results of MICS in 6 experienced centers in China.
MATERIAL AND METHODS: From September 2014 to July 2016, 1241 patients with cardiac conditions who underwent MICS procedures were randomly enrolled in 6 centers in China, and those patients were randomly selected for inclusion in this study. The MICS procedures were defined as any cardiac surgery performed through a less invasive incision, rather than a complete median sternotomy, mainly including mini-incision surgery (400, 32.2%), video-assisted approach (265, 21.3%), completely thoracoscopic approach without robotic assistance (504, 40.6%), and robotic procedure (55, 4.4%).
RESULTS: The 5 most common in-hospital complications were respiratory failure (28, 2.3%), reoperation for all reasons (19, 1.5%), renal failure (11, 0.9%), heart failure (9, 0.7%), and stroke (6, 0.5%). The multivariate logistic regression analysis results showed that cardiopulmonary bypass (CPB) time (P=0.033), aortic cross-clamp time (P=0.003), cannulation approach (P=0.010), and left ventricular ejection fraction (LVEF) (P=0.003) at baseline were all signiﬁcant risk factors of any in-hospital complication of MICS procedures.
CONCLUSIONS: From our experience, minimally invasive cardiac approaches are safe and reproducible, with acceptable CPB and aortic cross-clamp time duration and low mortality.
