Intraoperative Cardiac Events During Pediatric Cardiac Magnetic Resonance Imaging Under Anesthesia: A Retrospective Cohort Study.
Nearly 30% had intraoperative cardiac events during pediatric cardiac magnetic resonance imaging under anesthesia
Intraoperative Cardiac Events During Pediatric Cardiac Magnetic Resonance Imaging Under Anesthesia: A Retrospective Cohort Study.
Children with congenital heart disease (congenital heart disease) frequently undergo cardiac magnetic resonance imaging (magnetic resonance imaging) under anesthesia.
We aimed to determine the incidence and predictors of intraoperative cardiac events during pediatric cardiac magnetic resonance imaging using a recently proposed composite framework of intraoperative cardiovascular instability.
This single-center retrospective cohort study analyzed patients ≤ 18 years undergoing cardiac magnetic resonance imaging under anesthesia from 2013 to 2025.
Hypotension, vasopressor use, or severe cardiac events occurred in about 3 of 10 cases
Hypotension was most common (24.2%), followed by vasopressor administration (9.7%); no severe adverse cardiac events were observed.
Thirty-day mortality was 1.8% (6/330).
Independent predictors included increasing age (OR 1.13 per year, 95% CI: 1.04-1.21), and higher-acuity preoperative location, including neonatal intensive care unit (intensive care unit) (OR 4.42, 95% CI: 1.86-10.52) and pediatric intensive care unit (OR 4.84, 95% CI: 1.91-12.26).
Intraoperative cardiac events, primarily hypotension of unknown significance, were common during pediatric cardiac magnetic resonance imaging under anesthesia; no severe adverse cardiac events occurred.
Our findings highlight the physiologic complexity of this population and support the need for thoughtful perioperative risk stratification and management.
