Abstract

Prosthetic valve thrombosis (PVT) is one of the major causes of valve failure, which can be life-threatening. In clinical practice, a comprehensive approach that integrates several parameters of valve morphology and function assessed with 2D/3D transthoracic and transoesophage echocardiography (TTE) is usually the first modality for detecting prosthetic valve thrombosis, but PVT including large thrombotic masses may be underestimated or missed during initial TTE study. 3D echocardiography, especially with transeosophagesl echocardiography, can provide additional information and is increasing used. We present a case report of a 72 year-old female patient who had obstructive mitral mechanical valve and was diagnosed using 3D transesophageal echocardiography (3DTEE). The diagnosis was subsequently confirmed by surgery. 3DTEE is an excellent tool to obtain spatial information from cardiac structures and visualize cardiac pathologies in real-time, especially in evaluation of PVT. An en-face view of the mitral valve from left atrial provides the best method to detect thrombus. Therefore, patients may benefit from accurate diagnosis and proper treatment therapy with the utility of 3D TEE.
