BackgroundThis retrospective review focuses on peripartum anesthetic management and outcome of a series of five pregnant women with left ventricular noncompaction (LVNC).MethodsThe Mayo Clinic Advanced Cohort Explorer medical database was utilized to identify women diagnosed with LVNC who had been admitted for delivery at the Mayo Clinic in Rochester, Minnesota, between January 2001 and September 2021. Echocardiograms were independently reviewed by two board-certified echocardiographers, and those determined by both to meet the Jenni criteria and/or having compatible findings on magnetic resonance imaging (MRI) were included. Electronic medical records were reviewed for information pertaining to cardiac function, labor, delivery, and postpartum management.ResultsWe identified 44 patients whose medical record included the term "noncompaction" or "hypertrabeculation" and who had delivered at our institution during the study period. Upon detailed review of the medical records, 36 did not meet criteria for LVNC, and three additional patients did not receive the diagnosis until after delivery, leaving five patients with confirmed LVNC who had undergone six deliveries during the study interval. All five patients had a history of arrhythmias or had developed arrhythmias during pregnancy. One patient underwent emergency cesarean delivery due to sustained ventricular tachycardia requiring three intra-operative cardioversions.ConclusionsThis case series adds new evidence to that already available about pregnancies among women with LVNC. Favorable obstetrical outcomes were achievable when multidisciplinary teams were prepared to manage the maternal and fetal consequences of intrapartum cardiac arrhythmias and hemodynamic instability.Copyright © 2022 Elsevier Ltd.
