Clinical data patients, male, 51 years old. Physical examination found heart murmur 7 d. Physical examination: apex can be heard and 2/6 systolic murmur. Echocardiography (US) shows that the posterior left ventricular superior papillary muscle immediately above the size of about 40 mm × 26 mm slightly hyperechoic attached to the wall (Figure 1). Magnetic resonance imaging (MRI) tip: left ventricular posterior wall space lesions (Figure 2). Central cardiopulmonary bypass surgery, routine ascending aorta, the inferior vena cava intubation to establish cardiopulmonary bypass, the right atrium, atrial septal approach, the mitral valve probing shows the left ventricular posterior wall of a 20 mm ×
