RT Journal Article T1 Calcified right ventricular thrombus and antiphospholipid syndrome A1 De Agustín Loeches, José Alberto A1 Nuñez Gil, Iván Javier A1 Ruiz Mateos, Borja A1 Manzano, Maria del Carmen A1 Vivas Balcones, Luis David A1 Pérez De Isla, Leopoldo A1 Zamorano Gómez, José Luis A1 Macaya Miguel, Carlos AB Antiphospholipid syndrome has been associated with venous and arterial thrombotic events but intracardiac thrombosis is rare. We describe a case about a 30-year-old woman, admitted with a 6-month history of arthralgia, fatigue, and intermittent fever. Subsequent investigation revealed the presence of a large and calcified mass in the right ventricular outflow tract attached to the subvalvular tricuspid apparatus. Cardiac surgery was performed and histological examination demonstrated it to be composed entirely of calcified thrombus. Screening laboratory evaluation for hypercoagulable states confirmed the diagnosis of antiphospholipid syndrome.
