Lambl's excrescences (LEs) are unusual, yet significant etiology of thromboembolism. LEs are fibrous valvular strands typically occurring at coaptation lines of the left-sided valves. These occur from wear and tear of the valves and comprise of a dense core of collagenous and elastic fibrils enclosed by endothelium. Transesophageal echocardiography (TEE) remains the gold standard in its diagnosis. Asymptomatic LEs are closely monitored, while symptomatic lesions with history of thromboembolism are managed with antiplatelet drugs or are anticoagulated. Surgery is indicated in case of recurrent thromboembolic episodes occurring while on medications.
