Utility of Preoperative Cardiac Workup for Children With Very Severe Obstructive Sleep Apnea

open access: yesThe Laryngoscope, EarlyView.
In this retrospective study, we aimed to examine the prevalence and utility of obtaining a preoperative cardiac workup in children with very severe obstructive sleep apnea (OSA) prior to adenotonsillectomy. Of 144 patients with very severe OSA, 38 patients (26.4%) underwent a preoperative cardiac workup, and three of those 38 had abnormal findings ...

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

open access: yesJournal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

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

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Children with congenital heart disease (CHD) frequently undergo cardiac magnetic resonance imaging (MRI) under anesthesia. Although these procedures lack surgical stimulus, patients remain physiologically vulnerable, and the incidence of perioperative cardiovascular instability in this setting is poorly defined.
