The diagnostic procedure in which catheter is passed into a vein or artery and then guided into the heart as what?

Cardiac Catheterization

What is the procedure in which a catheter is passed into a vein or an artery and is guided into the heart?

The passing of a catheter into the heart is known as cardiac catheterization. This procedure is performed by a cardiologist in a catheterization lab, commonly called a cath lab. A long, thin tube is placed through a blood vessel to the heart.

How is pulmonary angiography different from cerebral and coronary angiography?

the guide wire and catheter are inserted into a vein instead of an artery, and are guided up through the chambers of the heart and into the pulmonary artery

Why is it necessary to inject a dye into the catheter during a cardiac catheterization?

After the catheter is guided into the coronary-artery system, a dye (also called a radiocontrast material) is injected to aid in the identification of any abnormalities of the heart.

How is angiography done?

Under sedation and local anaesthetic, a needle is introduced from the groin artery. A catheter is then introduced which is guided towards the heart. Once it reaches the heart vessels, a contrast dye is injected and the images are seen on the screen and recorded.

What is a Cardiac catheter?

A cardiac catheter is a thin, flexible tube used to diagnose and treat heart conditions. During a cardiac catheterization procedure, the catheter is inserted into a blood vessel in the arm, neck, or groin, and guided to the heart to assess blockages, measure pressures, or deliver treatments such as stents.

What type of catheter placement means the catheter is moved manipulating or guided into a part of the arterial system other than the vessel punctured?

Selective

Coronary artery stent?

A coronary artery stent is a small, metal mesh tube that is placed inside a coronary artery to help keep the artery open. To place the stent, a small incision is made in the groin area to reach the artery there. A catheter is guided through the groin artery into an area of the coronary artery which is blocked. The stent is inserted along with a balloon catheter and expands when the balloon is inflated. The stent is then left there to help keep the artery open.Reviewed ByReview Date: 03/21/2009David C.

What does a catheter ablation interrupt?

The technique of catheter ablation (meaning tube-guided removal) is used to interrupt the abnormal contractions in the heart, allowing normal heart beating to resume.

Percutaneous transluminal coronary angioplasty (PTCA)?

Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the heart muscle.The procedure begins with the doctor injecting some local anesthesia into the groin area and putting a needle into the femoral artery, the blood vessel that runs down the leg. A guide wire is placed through the needle and the needle is removed. An introducer is then placed over the guide wire, after which the wire is removed. A different sized guide wire is put in its place.Next, a long narrow tube called a diagnostic catheter is advanced through the introducer over the guide wire, into the blood vessel. This catheter is then guided to the aorta and the guide wire is removed. Once the catheter is placed in the opening or ostium of one the coronary arteries, the doctor injects dye and takes an x-ray.If a treatable blockage is noted, the first catheter is exchanged for a guiding catheter. Once the guiding catheter is in place, a guide wire is advanced across the blockage, then a balloon catheter is advanced to the blockage site. The balloon is inflated for a few seconds to compress the blockage against the artery wall. Then the balloon is deflated.The doctor may repeat this a few times, each time pumping up the balloon a little more to widen the passage for the blood to flow through. This treatment may be repeated at each blocked site in the coronary arteries. A device called a stent may be placed within the coronary artery to keep the vessel open. Once the compression has been performed, contrast media is injected and an x-ray is taken to check for any change in the arteries. Following this, the catheter is removed and the procedure is completed.Reviewed ByReview Date: 06/28/2011David Zieve, MD, MHA, Medical Director, A.D.A.M., Inc., and Michael A.

What is CPT code 76936?

It used to be for Echo Guided Artery Repair, or US guided Compression study, or Pseudoaneurysm But it is a dead code now.

Directional coronary atherectomy (DCA)?

Directional Coronary Atherectomy (DCA) is a minimally invasive procedure to remove the blockage from the coronary arteries and allow more blood to flow to the heart muscle and ease the pain caused by blockages.The procedure begins with the doctor injecting some local anesthesia into the groin area and putting a needle into the femoral artery, the blood vessel that runs down the leg. A guide wire is placed through the needle and the needle is removed. An introducer is then placed over the guide wire, after which the wire is removed. A different sized guide wire is put in its place.Next, a long narrow tube called a diagnostic catheter is advanced through the introducer over the guide wire, into the blood vessel. This catheter is then guided to the aorta and the guide wire is removed. Once the catheter is placed in the opening or ostium of one of the coronary arteries, the doctor injects dye and takes an x-ray.If a treatable blockage is noted, the first catheter is exchanged for a guiding catheter. Once the guiding catheter is in place, a guide wire is advanced across the blockage, then a catheter designed for lesion cutting is advanced across the blockage site. A low-pressure balloon, which is attached to the catheter adjacent to the cutter, is inflated such that the lesion material is exposed to the cutter.The cutter spins, cutting away pieces of the blockage. These lesion pieces are stored in a section of the catheter called a nosecone, and removed after the intervention is complete. Together with rotation of the catheter, the balloon can be deflated and re-inflated to cut the blockage in any direction, allowing for uniform debulking.A device called a stent may be placed within the coronary artery to keep the vessel open. After the intervention is completed the doctor injects contrast media and takes an x-ray to check for any change in the arteries. Following this, the catheter is removed and the procedure is completed.Reviewed ByReview Date: 05/23/2011Michael A.
