A Case Report: Iatrogenic Aortic Dissection During Minimally Invasive Mitral Valve Surgery: A Successful Management

Abstract Minimally Invasive Valve Surgery (MIVS) are on the rise in the field of heart valves surgery, and considered more favorable than traditional open approach. Nevertheless, the complication of Iatrogenic Aortic Dissection (IAD) remains a concern. We present a case, highlighting the clinical management of Acute IAD of ascending aorta during Minimally Invasive Mitral Valve Surgery (MIMVS) in a 61-year-old lady. Diagnosis of primary mitral regurgitation (MR) secondary to mitral valve prolapse was made and surgery was conducted. Exploration showed a hematoma in ascending aorta, which was confirmed by Trans-Esophageal Echocardiography (TEE) leading to Aortic Dissection diagnosis. Thoracotomy was done. Elephant stent graft and mitral valve repair were conducted successfully.
