During endomyocardial biopsy, the bioptome is advanced into which chamber after crossing which valve?

Explanation:
Endomyocardial biopsy is usually done via a venous route. The bioptome is inserted through a vein, guided into the right atrium, and then crossed the tricuspid valve into the right ventricle to obtain tissue—typically from the interventricular septum. This approach avoids arterial access and the higher risks associated with left-sided sampling, making the right ventricle the standard target after crossing the tricuspid valve.
