Massive left atrial calcification (porcelain atrium) can be associated with recurrent thrombosis even when anticoagulant levels are therapeutic.
Porcelain atrium may predispose to recurrent LA thrombosis despite therapeutic anticoagulation; leaves open optimal management strategies.
Sporadic calcification of the left atrium is frequently observed in patients with long standing rheumatic valvular heart disease. However, massive calcification involving the entire left atrium, the so-called porcelain or coconut atrium, is extremely rare.
