A right heart catheterization is a diagnostic procedure that involves the insertion of a catheter into the right side of the heart to assess its function and measure pressures within the heart chambers and pulmonary arteries. The procedure begins with the preparation of the catheter access site, which is typically located in the right femoral vein in the groin area. The skin is thoroughly cleansed to minimize the risk of infection, and a local anesthetic is administered to ensure patient comfort during the procedure. A small incision is made in the skin, allowing for the insertion of a needle into the blood vessel. Following this, a sheath is placed to facilitate the passage of the catheter. A guidewire is then threaded through the femoral vein, progressing through the external iliac vein and inferior vena cava, ultimately reaching the right atrium of the heart. The catheter is carefully advanced over the guidewire into the inferior vena cava and subsequently into the right atrium, right ventricle, and pulmonary arteries. Throughout this process, the right heart chambers are visually inspected, and critical measurements of pressure and oxygen levels are taken to evaluate cardiac function. Additionally, the tricuspid and pulmonary valves are examined for any abnormalities. If necessary, a separately reportable angiogram of the right heart and/or pulmonary arteries may be performed to provide further diagnostic information. Upon completion of the procedure, the catheter is withdrawn, and compression is applied to the venous access site to prevent bleeding, followed by the application of a dressing to protect the site.
