A 64-year-old man was admitted to our department because of recent onset of weakness and shortness of breath. He had undergone a surgical mitral commissurotomy in 1977 and a bioprosthetic mitral replacement in 2004. The clinical presentation demonstrated normal blood pressure, no signs of congestive heart failure, no fever and a 3/6 systolic mitral murmur; he was in permanent atrial fibrillation.

Transthoracic echocardiography showed severe left atrial enlargement and the presence of a paravalvular leak. Two-dimensional (2D) transoesophageal echocardiography (TEE) clearly demonstrated severe paravalvular regurgitation (Figure 1A) but real-time three-dimensional (3D) TEE allowed precise location of the paravalvular regurgitant jet at the inferomedial part of the annulus, slightly distant from the prosthetic ring, with a circular and expansive shape (Figure 1B). On colour-flow Doppler imaging, the area of dehiscence was estimated as being close to 0.7cm2 (Figure 1C and D). Owing to the high risk of a third surgical procedure, the absence of signs of congestive heart failure or haemolysis and the requirement of only a minor dose of diuretics, the patient was discharged with a scheduled visit at 1 month.

Zoom

Real-time 3D-TEE imaging is a useful echocardiographic modality for the localization and quantification of paravalvular leak. It can provide an en face view of the mitral prosthesis, allowing accurate determination of the location and number of paravalvular dehiscences and is crucial during percutaneous intervention. In the present case, the diagnosis was already obvious in 2D TEE but 3D TEE provided nice simple and intuitive visualization of the leak.
