Figure 4. Serial Transthoracic echocardiography (TTE). (A, B) TTE 1 h after the catheterization shows mild mitral regurgitation. (C) TTE 4 days after the admission shows the head portion of the anterolateral papillary muscle swinging into the left atrium during systole (arrow). (D) TTE 4 days after the admission shows severe mitral regurgitation with a posterior jet caused by frail anterior mitral valve leaflet. LA – left atrium; LV – left ventricle; TTE – transthoracic echocardiography.
