A myocardial biopsy, also called a heart biopsy, is an invasive procedure that involves using a bioptome (a small catheter with a grasping device on the end) to obtain a small piece of heart muscle tissue that is sent to a laboratory for analysis.
Your doctor uses myocardial biopsy to:
- Evaluate or confirm the presence of rejection after heart transplant
- Diagnose myocarditis (inflammation of the heart muscle)
- Diagnose cardiac amyloidosis
