Abstract:
Collaterals are described between coronary and pulmonary arteries after orthotopic heart transplantation. It is likely the collaterals developed as a result of adhesions in the pericardial space. This is a previously unrecognized complication of heart transplantation with potential clinical implications, as coronary to extracardiac artery collaterals have been shown to cause myocardial ischemia.
