Pneumothorax , or lung collapse, can also occur as a result of a puncture to the lung. This is more common when the catheter is inserted into the neck or chest veins.
The most dangerous risk of a PAC procedure is pulmonary artery rupture, which has a 50 percent mortality rate , according to one study. This is a rare complication that most often affects women over 60 years old who have PAH. Swan-Ganz catheterization and other PACs have been the subject of controversy over the years. This is in part because of a study led by Alfred F. Connors, Jr. According to the study , the PAC procedure might increase the risk of death for people who are critically ill.
Additional studies have since questioned the usefulness of the Swan-Ganz catheterization as unreliable, inaccurate, and poorly understood and misinterpreted by medical personnel. More recent technologies offer less invasive and reliable results. They include:. Despite these controversies, PAC still has a role in the diagnosis and management of PAH and acute right-ventricular failure.

Textbook of Interventional Cardiology. Updated by: Thomas S. Editorial team. Swan-Ganz - right heart catheterization. First, the doctor will insert an intravenous, or IV line into one of the blood vessels in your groin or neck. Through this IV line, your doctor will pass a thin, flexible tube called a catheter. That tube will be threaded into either the left or right side of your heart.
The doctor will use an x-ray as a guide to see where the catheter is going. While the catheter is in place, your doctor can check how well the blood is flowing into and out of your heart, and through the arteries around your heart, collect blood samples from your heart, measure the oxygen level in your heart, and even take a tiny piece of heart tissue, called a biopsy, when there's a situation of unexplained heart failure.
Cardiac catheterization is a safe procedure when performed by an experienced medical team. But, some possible risks include bleeding, infection, and blood clots. A heart attack or a stroke can happen in very rare situations. But, remember, it's done in a closely supervised setting in a hospital.
After a cardiac catheterization, your doctor should have a pretty good idea of what's causing your heart, valve, or blood vessel problem.
Knowing exactly what the problem is can help your doctor find just the right way to treat your particular problem. You should not eat or drink anything for 8 hours before the test starts. You may need to stay in the hospital the night before the test. Otherwise, you will check in to the hospital the morning of the test.
You will wear a hospital gown. You must sign a consent form before the test. Your provider will explain the procedure and its risks. You may be given medicine to help you relax before the procedure. You will be awake and able to follow instructions during the test. You may feel some discomfort when the IV is placed into your arm.
You may also feel some pressure at the site when the catheter is inserted. In people who are critically ill, the catheter may stay in place for several days. It may also be done to monitor for complications of a heart attack.
