Two-dimensional echocardiographic scan showing the supra-annular location of the mechanical mitral valve (red double arrow and green arrow). A defect noted at the level of the native lateral mitral annulus near the end of the anterolateral wall of the LV measuring 1.5 cm and connected to a huge cavity (red star) measuring 2.9x8 cm raised the suspicion of a left atrial appendage aneurysm. LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle

A myocardial defect located below the lateral annulus of the mitral valve near the end of the anterolateral wall of the LV measuring 1.5 cm and connected to a huge cavity measuring 3x8 cm was noted (Fig. 1). Colour Doppler showed flow into the cavity and back to the LV (Fig. 2 and Video 1).
Doppler colour flow showed flow with a to-and-fro pattern between the LV through the defect and aneurysmal cavity of the left atrial appendage (red arrow). LA, left atrium; LV, left ventricle

Colour Doppler showed flow into the cavity and back to the LV (Fig. 2 and Video 1). However, on colour Doppler, a significant paravalvular leak was detected at the sewing ring's insertion into the coumadin ridge with an accelerated systolic flow mainly directed into the left upper pulmonary vein (Fig. 3 and Video 2).
Transesophageal echocardiography, two-chamber view. Doppler colour flow showed a significant paravalvular leak detected at the point of insertion of the sewing ring into the coumadin ridge with an accelerated systolic flow (red arrow). LA, left atrium; LV, left ventricle
