The Effect of Surgery Started at Different Time Points During the Day on the Clinical Outcomes of Mitral Valve Surgery
This study investigates the impact of mitral valve surgery conducted at different times of the day (morning, afternoon, and evening) on short-term and long-term clinical outcomes. Across 947 patients from January 2018 to December 2020, divided into morning, afternoon, and evening groups based on surgery start time, results showed no significant differences in long-term mortality, stroke risk, reoperation rates, or in-hospital outcomes such as cardiopulmonary bypass time and ICU length of stay. The study concludes that mitral valve surgery is safe regardless of the time of day it is performed.
