- Abstract: We report a case of mitral valve replacement without aortic cross clamp in a patient with MitraClip failure. The patient is an 83-year-old man with a history of coronary artery bypass surgery 31 years earlier. He developed heart failure due to severe mitral regurgitation. He underwent MitraClip, but it caused mitral stenosis and hemodynamic instability. Considering the severe calcification of the ascending aorta and previous bypass grafts, typical median sternotomy surgery with cross clamp had to be avoided. We performed mitral valve replacement via right thoracotomy under ventricular fibrillation. The postoperative course was favorable. Mitral valve surgery with ventricular fibrillation could be undertaken safely for a patient with difficulty in aortic cross clamp.
