Reoperative valve surgery is known to be more complex and associated with increased morbidity and mortality, especially for patients with patent coronary artery bypass grafts. A 69-year old man with a history of coronary artery bypass grafting was referred to our hospital with breathing difficulties and a heart murmur. Bypass grafts were all patent, but due to severe ischemic mitral valve regurgitation, we performed beating heart mitral valve replacement via right thoracotomy. The procedure was performed with video assistance, and both the anterior and the posterior chordae tendineae were preserved. The postoperative course was uneventful. He was discharged 7 days after surgery without any complications. This technique is a safe and feasible option for a mitral valve reoperation that avoids graft injuries, minimizes the risks of bleeding, and shortens the operative time.
