a Two-dimensional transthoracic echocardiogram in apical four-chamber view showed an aneurysm-like structure measuring (29 × 25 mm) suggestive of a submitral aneurysm. Color Doppler imaging revealed blood inflow from LV to pseudoaneurysm (b) and from pseudoaneurysm to LV (c) through a narrow neck (measuring 3 mm) in systole. d Contrast-enhanced cardiac computed tomography confirmed the pseudoaneurysm. RV: right ventricle. RA: right atrium. LV: left ventricle. LA: left atrium. PA: pseudoaneurysm. PN: pseudoaneurysm neck
