Supplementary Material

The supplementary movies demonstrate the prosthetic mitral valve paravalvular dehiscence and severe regurgitation using Apical 2 chamber 2-Dimensional Transthoracic Echocardiography (Online Video 1) and in more detail using mid-oesophageal 2-Dimensional Transoesophageal Echocardiography with colour Doppler (Online Videos 2 and 3). The sutures can be clearly seen on the atrial surface of the prosthetic mitral valve. Real-time 3-Dimensional Transoesophageal Echocardiography accurately shows the crescent shaped postero-medial paravalvular dehiscence from the atrial aspect (Online Video 4) compared to ventricular aspect (Online Video 5). The severe prosthetic mitral valve paravalvular regurgitant jet is highlighted in the 3-Dimensional real time colour Doppler Transoesophageal echo (Online Video 6).
