How does a percutaneous transluminal coronary angioplasty (PTCA) improve blood flow?
A. The balloon stretches the vessel wall, fractures the plaque, and enlarges the vessel lumen.
B. Medication is delivered through the catheter that dissolves the plague and enhances vessel
patency.
C. The balloon removes blood clots from the vessel improving patency of the vessel.
D. The balloon compresses the plaque against the vessel wall enlarging the vessel lumen. -
