Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) pregnancies affected by major cardiac events stratified by prepregnancy cardiac history. A. Most pregnancies were completed without major cardiac events. Heart failure ≥ Class C occurred exclusively in high-risk pregnancies begun with major structural right ventricular (RV) abnormalities (by 2010 Task Force Criteria¹⁶). Ventricular arrhythmias did not recur during pregnancy. VA, sustained ventricular arrhythmia or appropriate implantable cardioverter defibrillator therapy for a ventricular arrhythmia. B. Worsening cardiac symptoms occurred in the absence of major cardiac events in 9 pregnancies.
