Key result
Prosthetic mitral valve patient develops unusually large left atrial thrombus with thromboembolic and hemorrhagic complications.
Case Report (n=1)
Highlights the risk of severe thromboembolic and hemorrhagic complications in patients with mechanical prosthetic valves and the need for high clinical suspicion and prompt echocardiographic diagnosis.
Large LA thrombus with mixed complications in mitral prosthesis warrants vigilance; leaves open optimal anticoagulation strategies.
Patients with prosthetic cardiac valves are at high risk for thromboembolic complications and need life long anticoagulation with warfarin, which can be associated with variable dose requirements and fluctuating level of systemic anticoagulation and may predispose to thromboembolic and or hemorrhagic complications. Prosthetic cardiac valve thrombosis is associated with high morbidity and mortality. A high index of suspicion is essential for prompt diagnosis. Transthoracic echocardiography, and if required transesophageal echocardiography are the main diagnostic imaging modalities. Medically stable patients can be managed with thrombolytic therapy and anticoagulation, while some patients may require surgical thrombectomy or valve replacement. We present a case report of a patient with prosthetic mitral valve and an unusually large left atrial thrombus with both thromboembolic and hemorrhagic complications.

Sanjay Mehra (2015) conducted a case report in Prosthetic mitral valve thrombosis (n=1). Prosthetic mitral valve was evaluated. A patient with a prosthetic mitral valve developed an unusually large left atrial thrombus presenting with both thromboembolic and hemorrhagic complications.
