Question: Can any tell me what Percutaneous Transluminal Coronary Angioplasty (PTCA) is? I need to know what it is in plain English, I keep getting these super scientific answers. I know its a medical term, but can anyone break it down for me simply?

Answer: This procedure is done in a cardiac catheterization lab, not a regular operating room. Usually it is done by a cardiologist especially trained in interventional cardiology, but occasionally another specialist might do it also. Percutaneous means "through the skin".In this case the cardiologist will make a puncture, usually in the groin, occasionally in the arm, into an artery through which a guidewire and catheter is placed. It is run through the arteries and up to the entrance to the heart. The coronary arteries are the first arteries that come off the aorta (the main artery taking blood to the whole body) after it leaves the heart. They can use fluoroscopy -a sort of X-ray - to see where they are going with the guidewires. After the arteries involved in blockages have been identified by a cardiac catherization (shoot dye thru the catheter into the coronary arteries to see and measure the extent of any blockages) then a intervention (PTCA) can be done if needed. Sometimes it is done immediately after the cardiac catheterization, but sometimes it can be done later. Occasionally if a person needs several arteries unblocked, it will be done in so-called staged procedures. They do the most dangerous one first and then the others at a later date. What the procedure consists of: The tranluminal coronary angioplasty basically consists of taking a special catheter with a tiny balloon on its tip up to the point of a blockage in the artery. The balloon is then inflated to break up the plaque that is causing the blockage (the catheter also vacuums up any fragments that might result) so that the inside dimensions of the artery (its lumen) are increased. The flow through the artery is measured before and after the procedure to make sure that the artery has been adequately opened. That's basically what an intervention is. Often, but not inevitably, the cardiologist will place a stent in the area to hold it open, so that is usually part of the procedure and might be referred to as "PTCA with stent placement." Sometimes, instead of the balloon to open an artery, the cardiologist feels that the blockage will not be amenable to that procedure. In that case they may do something called a "rotational atherotomy" which is using a tiny rotating blade to peel away the atherosclerosis from the inside of the artery. I think that this is much less common than PTCA. The "transluminal" portion of the name PTCA refers to the fact that this procedure is accomplished by going through the artery, not operating on it from outside. The "coronary" refers to the heart's blood vessels. The term "angioplasty" comes from the root "angio" which refers to blood vessels and "plasty" which is from a root word relating to a procedure to form or shape an organ. Medications are used during and after the procedure to try to minimize the chances of the artery closing up again. The duration of medication depends in part on the location in the arteries, the type of stent if any is used, and the cardiologist's preference. The medications (chiefly Plavix or clopidgrel) that are taken by outpatients are quite expensive, but extremely important to keep the arteries from reblocking. Hope this is helpful.
