Biopsy after Heart transplants

Is the coronary angiogram the way we access the heart for follow up biopies after a heart transplant to check for rejection?

technically no

the coronary angiogram is the process of injecting dye in the coronary arteries to get pictures of the arteries. A myocardial biopsy is the process of taking a piece of the heart muscle for analysis. Both are done by cardiac catheterization, the process of advancing a catheter from a peripheral artery through the aorta to the heart. In the case of coronary angiogram, they catheter stops at the origin of the aorta where the coronary arteries originate. The catheter can be advanced into the left ventricle to obtain the biopsy. It's all semantics...
