- Abstract: A 73-year-old woman presented with epigastric discomfort and lightheadedness. She was admitted to another hospital with congestive heart failure due to severe aortic and mitral regurgitation. However, her heart failure was refractory to medical treatment, necessitating transfer to our hospital for surgical treatment. Emergency surgery was performed for worsening heart failure after admission to our hospital. Intraoperative findings showed aneurysms of the ascending aorta and aortic root and avulsion of the aortic valve commissure between the right coronary and non-coronary cusps. Replacement of the ascending aorta and aortic root replacement using the Florida sleeve method as well as double valve replacement (mitral and aortic) were performed with a favorable outcome. Histopathological examination showed myxomatous degeneration, which suggested that it could have contributed to avulsion of the aortic valve commissure.
