Percutaneous coronary interventions involve:

A. recanalizing a blocked coronary artery by passing a balloon or stent through a catheter via a peripheral artery.
B. using a large vein from one of the lower extremities to reroute blood flow past an occluded coronary artery.
C. passing a 2-mm catheter through the femoral artery and administering a fibrinolytic agent through the catheter.
D. passing a guide wire through one of the external jugular veins to directly visualize an occluded coronary artery.
