Figure 1 : 

A. Preoperative coronary angiography showing acute occlusion in the first obtuse marginal artery (left box, white arrow). After on-site percutaneous ballooning, blood flow was restored (middle box, arrowhead). The posterior descending artery was supplied by the right coronary artery, thus this coronary system had right dominance (right box). B. Preoperative echocardiogram revealed acute mitral regurgitation with suspicious papillary muscle rupture (arrow) and regurgitant jet flow was noted in the colour Doppler image (upper small image). C. Preoperative chest X-ray showing pulmonary oedema and intra-aortic balloon pump (arrow).
