Lessons Learned from an Erroneous Surgery : Inversely Implanted Apicoaortic Valved Conduit / 日本心臓血管外科学会雑誌

A 62-year-old woman with severe aortic stenosis underwent apicoaortic bypass grafting. The graft was implanted inversely at first ; on the next day, it was re-implanted in the right direction. She recovered once from heart failure ; however, on postoperative day (POD) 74, she died from respiratory failure.

Throughout the investigation, we provided relevant information about the event and explanations. We presented our apologies the patient's family and offered to compensate them for their losses.
