Intraoperative Cardiac Events During Pediatric Cardiac Magnetic Resonance Imaging Under Anesthesia: A Retrospective Cohort Study

The authors aimed to determine the incidence and predictors of intraoperative cardiac events during pediatric cardiac magnetic resonance imaging (MRI) under anesthesia, given the physiological vulnerabilities of children with congenital heart disease. In their study of 330 cases, they found that 29.7% experienced intraoperative cardiac events, primarily hypotension, with independent predictors including increasing age and higher-acuity preoperative locations. The findings underscore the need for careful perioperative risk assessment and management in this patient population.
