These flashcards cover key concepts related to heart surgeries and cardiac assistive devices.

What is the goal of a coronary artery bypass graft?

To bypass damaged segments of coronary arteries by using a blood vessel from the chest or leg.

What does percutaneous transluminal coronary angioplasty involve?

Dilating the coronary artery using a tiny balloon attached to a long, thin tube.
