Management of catecholaminergic polymorphic ventricular tachycardia in pregnancy: a case report

Objective To report the case of a successful pregnancy in a patient with catecholaminergic polymorphic ventricular tachycardia with a history of cardiac arrest and placement of an implantable cardioverter defibrillator (ICD). Case(s) A 29-year-old Caucasian G1P0 presented to the maternal fetal medicine service at seven weeks gestation with known CPVT. She was medically managed with nadolol and experienced no arrhythmias or ICD shocks during her pregnancy. Her pregnancy was complicated by severe fetal growth restriction. She ultimately delivered by urgent cesarean section due to fetal intolerance of labor. Conclusion Episodes of catecholaminergic polymorphic ventricular tachycardia during pregnancy can be life-threatening for both mother and baby, though successful management is possible with care from a multidisciplinary team.
