A 65-year-old male patient was considered inoperable by conventional means for a previous triple coronary artery bypass grafting with a patent in situ right internal mammary artery graft to the left anterior descending artery crossing the thorax at midline directly behind the sternum. Transcatheter aortic valve implantation failed due to loss of the prosthetic device in the left ventricular outflow tract. Mandatory conversion was accomplished by an inferior partial T-shape sternotomy and extracorporeal circulation draining from the right atrium and feeding into the right femoral artery. A conventional 27-mm aortic valve bioprosthesis was successfully implanted during deep hypothermic circulatory arrest. The patient recovered normally exhibiting no neurological or cardiocirculatory complications.
