Heart Information

Right Heart Catheterisation

2026/03/13
What is it?
A medical procedure used to diagnose and evaluate conditions affecting the right side of the heart. It involves inserting a thin, flexible tube (catheter) into a vein, usually in the neck or groin, and threading it to the right side of the heart. 
Why is it done?
To measure pressures in the right atrium, right ventricle, and pulmonary artery. This procedure provides valuable information about how well the heart is functioning and can guide treatment decisions. 
Does it hurt?
Patients may experience some discomfort during the procedure, particularly at the site where the catheter is inserted. Local anaesthesia is typically used to minimize pain, and many patients report only mild discomfort or pressure during the procedure. 
Potential risks and complications
While right heart catheterization is generally safe, there are some potential risks and complications, including bleeding at the catheter insertion site, infection, damage to blood vessels or the heart, arrhythmias (irregular heartbeats) and blood clots. Overall, the benefits of obtaining detailed information about heart function often outweigh the risks associated with the procedure.
