case_images: Implantation of a 26-mm Evolut PRO+ valve (Medtronic, Minneapolis, MN, USA) in a slightly lower position than normal and deployed via the femoral approach was accomplished (Fig. 1). Coronary angiography revealed no stenosis in the left coronary artery ostium (Fig. 1).
case_images: Transoesophageal echocardiography demonstrates mitral regurgitation caused by rupture of the anterior papillary muscle of the left ventricle.

case_images: However, on transoesophageal echocardiography, severe MR was observed, caused by rupture of the anterior papillary muscle of the left ventricle (Fig. 2).
case_images: The anterior mitral leaflet with the ruptured anterior papillary muscle is resected.

case_images: The anterior mitral leaflet with the ruptured anterior papillary muscle was resected (Fig. 3).
case_images: Pathological examination of the papillary muscles suggested early infarction 1 to 3 days after onset.

case_images: Pathological examination of the papillary muscles suggested early infarction 1 to 3 days after onset, and the results indicated that papillary muscle rupture associated with infarction was suspected (Fig. 4).
