Transoesophageal echocardiogram. a and c. Part of the posterior leaflet protrudes into the left atrium at a 129° (a) and 63° (c) angle in early systole (arrows). LA = left atrium; LV = left ventricle; Ao = Aorta. b and d. The colour Doppler images shows a considerably large proximal isovelocity surface area (PISA) (arrowheads) and a prominently eccentric mitral regurgitation at a 129° (b) and 63° (d) angle in end-systole. e. Three-dimensional transoesophageal echocardiogram, observed from the left atrium towards the mitral valve annulus, showing the 6-mm in diameter aneurysm on the posterior leaflet (arrow). The aneurysm was located at mid-posterior leaflet (P2) near lateral-posterior leaflet (P1). f. Three-dimensional full-volume colour acquisition of the mitral valve illustrating the spatial relationship between the MVA and the MR jet
