Overview

Explanation

PTCA involves insertion of a balloon-tipped catheter into the coronary artery to compress a plaque, thereby opening a stenosed or blocked artery. The first answer describes coronary bypass graft surgery and the second answer describes a procedure called atherectomy where plaque is removed through a catheter-ended blade or burr. The procedure does not include placing a monitor on the tip of a catheter for surgery visualization.
