Teen pregnancy in the setting of familial dilated cardiomyopathy: a case report

Abstract

BackgroundWomen with pre-existing forms of familial cardiomyopathy are at increased risk for morbidity and mortality due to hemodynamic changes of pregnancy. There is a lack of consensus about the management and care for these patients given the rarity of this condition. This case represents possibly the youngest pregnant familial dilated cardiomyopathy patient to deliver and the youngest patient to be fitted for a wearable cardiac defibrillator in the postpartum period.Case PresentationA 14-year-old gravida 1 with familial dilated cardiomyopathy presented late for prenatal care at 38 weeks, which precluded typical care plans including baseline and serial echocardiograms, medication management, and routine prenatal care. An echocardiogram showed severely decreased left ventricular systolic function compared to studies from one year prior. Three days later the patient presented in labor and had a spontaneous vaginal delivery complicated by postpartum hemorrhage. Her postpartum course was notable for persistence of decreased cardiac function testing and placement of a wearable cardiac defibrillator for prevention against life threatening arrhythmias.ConclusionThis case report adds to the literature on pregnancy complicated by familial dilated cardiomyopathy and describes management best practices and considerations during the antepartum, intrapartum, and postpartum periods.
