Abstract: Case 1 of stuck valve was an 84 year old man, 25 years after mitral valve replacement (MVR) using a mechanical valve. Case 2 was a 67 year old woman, 18 years after the previous operation. These patients underwent re-do replacement of the prosthesis with a minimally invasive right thoracotomy approach using a microscope. Re-do cardiac surgery is commonly regarded high risk on account of difficulty in peeling the adhension, risk of injury to the heart, lung or large vessels, longer operation time, greater amount of transfusion, higher invasion and longer admission. In both cases however, because of microscope-assist and right thoracotomy MICS technique, we safely and successfully completed the operation without any unplanned troubles. We finally had a good course with a short admission, no perioperative transfusion or no perioperative complication.
