Abstract

Antiphospholipid syndrome (APS) is well known for its association with arterial and venous thrombosis. Intracardiac thrombosis-more often involving the right atrium-is a serious manifestation of the disease. We describe an APS case with a thrombosis in the right ventricular outflow tract (RVOT), which underwent regression after aggressive anticoagulation.

Keywords: antiphospholipid syndrome; intra cardiac thrombosis; right ventricular outflow tract thrombosis; transthoracic echocardiography.
