Background: Minimally invasive cardiac surgery (MICS) has constantly evolved over the past years, and new technologies have been introduced. The aims of this study were to analyze the evolution of our 10-year experience in MICS and to highlight outcomes in different spans of time. Methods: Patients undergoing MICS for mitral valve, tricuspid valve, and/or atrial septal defect or atrial masses from November 2005 to November 2015 were retrospectively analyzed. A comparative analysis was performed by identifying 2 groups: the control group (in the first time span of our experience) and the tailored group (patients who underwent surgery after a full preoperative anatomic evaluation with allocation to the proper setting). Results: During the study period 971 patients underwent MICS. MICS procedures increased from 44% in 2006 to 96% in 2015. Subgroup analysis revealed a significant decrease in the rate of procedures performed with retrograde arterial perfusion (99.1% vs 91.7%, P < .0001), a significant increase in the rate of complex mitral valve procedures (22.4% vs 7.9%, P < .0001), and a significant decrease in the rate of stroke (from 5.2% to 1%, P < .001) in the tailored group. The logistic regression analysis showed that the tailored approach was a protective factor against neurologic complications. Conclusions: The present study shows the considerable and attractive results of our decision-making process based on the tailored approach. The 10-year outcome analysis demonstrated a trend toward a progressive decrease in the overall rate of postoperative complications and a significant protective effect of the tailored approach on the occurrence of stroke.

Abstract
