Background: Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by progressive fibrous or fibrofatty tissue replacement of the right ventricular myocardium. Interspersed adipocytes and fibrous tissue may provide foci for arrhythmias. The clinical spectrum of ARVD may include asymptomatic premature ventricular complexes to ventricular tachycardia and sudden death. There is currently little information about ARVD in pregnancy.
Case: A 29-year-old primigravida, diagnosed with ARVD 1 year prior to pregnancy, underwent a full-term, uncomplicated pregnancy and delivery while maintained on acebutolol and an implanted cardioverter defibrillator. Her infant was born without an apparent cardiac anomaly or heart rate abnormality.
Conclusion: Successful management of pregnancy complicated by ARVD can be accomplished with an implanted cardioverter defibrillator and an antiarrhythmic agent. Such patients should be managed with close monitoring during pregnancy for signs and symptoms of arrhythmia and preventive obstetric care appropriate to their clinical profile to optimize normal deliveries.
