Excerpt

A 56-year-old man was admitted for transoesophageal echocardiography (TEE) evaluation before electrical cardioversion of persistent atrial fibrillation to sinus rhythm. He had undergone mitral valve replacement with a bileaflet prosthetic mitral valve (SORIN prosthetic valve) for rheumatic disease 3 months previously. Inadequate anticoagulation was noted with an INR of 1.7. TEE revealed the presence of thick mobile filamentous fibrin strands attached to the prosthesis sewing ring with a diastolic movement within the prosthesis without obstruction (normal 5 mmHg transprosthetic mean pressure gradient) (Fig.  1 and video 1). Three-dimensional transoesophageal echocardiography showed the presence of a circular thrombus like a crown attached to the whole prosthesis sewing ring protruding between the prosthesis leaflets and the sewing ring (Fig.  2 arrows and video 2) highlighting the presence of sewing ring thrombosis when compared with two-dimensional TEE evaluation of the same image. Considering the presence of non-obstructive thrombosis, a conservative approach with heparin was used.
