Iatrogenic Acute Ascending Aortic Dissection During Combined Heart/Liver Transplant for Amyloidosis.

We report a case of iatrogenic acute type A aortic dissection (ATAAD) during a combined heart-liver transplant in a patient with amyloid-associated cardiac and hepatic failure. The patient developed ATAAD of the recipient's aorta during the heart transplantation. Because there was no sign of malperfusion or proximal extension into the donor aorta, we proceeded with the liver transplantation and continued medical management for ATAAD. The patient was discharged uneventfully 30 days after the transplant, and computed tomography coronary angiogram after 4 months showed stable dissection. During a heart transplant, ATAAD of the native aorta without malperfusion syndrome can be managed conservatively with close progress monitoring.
