The patient is a 71-year-old man who developed a ventricular septal perforation (VSP) with septal dissection after acute myocardial infarction (AMI). Heart failure symptoms were stabilized with intra-aortic balloon pumping and diuretics, and the VSP was closed via a left ventriculotomy approach on day 23 after AMI and day 12 after identification of the VSP. The right ventricular perforation was closed with a single patch of bovine pericardium, and the left ventricular perforation was closed with a double patch using the infarct exclusion technique. The septal dissection cavity was closed with BioGlue surgical adhesive (Artivion, Inc., Kennesaw, GA, USA). The patient's postoperative course was uneventful and he was discharged home on postoperative day 36. His NYHA functional class was I at 1 year and 6 months after surgery.

A 73-year-old man had been followed up in our hospital after surgery for mitral regurgitation. At the age of 67, he underwent mitral valve plasty through a right mini-thoracotomy approach for atrial functional mitral regurgitation at our hospital. The mean trans-mitral pressure gradient was 5 mmHg after surgery but no heart failure symptoms were observed. At the age of 72, he began to notice fatigue during exertion. Transthoracic echocardiography revealed that the mitral valve regurgitation was controlled to a trace level, but the mean trans-mitral pressure gradient increased to 10 mmHg. Transesophageal echocardiography and contrast-enhanced cardiac computed tomography revealed the restricted opening of the mitral valve and pannus formation around the prosthetic ring. We thus diagnosed mitral stenosis due to pannus overgrowth. He underwent pannus excision and removal of the artificial ring. Postoperative echocardiography revealed that the mean trans-mitral pressure gradient was reduced to 3 mmHg and no residual mitral regurgitation was observed. He was discharged on postoperative day 11 with no major symptoms. He was in New York Heart Association functional class I at 1 year after the surgery and continues to be an outpatient.
