Recurrent Ventricular Tachycardia and Peripheral Gangrene in a Young Child.

A 10-year-old girl presented with sudden onset recurrent ventricular tachycardia and symmetrical distal peripheral gangrene. She also had pulmonary thromboembolism and cerebral sinus venous thrombosis. Investigations revealed anemia, hemolysis, hypocomplementemia, and elevated IgM anti-beta2 glycoprotein antibody levels. Electrocardiogram and echocardiogram suggested features of a rare cardiac anomaly, which was confirmed at autopsy.
