A right heart catheterization is a diagnostic procedure specifically designed for patients with congenital cardiac anomalies. This procedure involves the insertion of a catheter into the right side of the heart to assess its structure and function. The process begins with the preparation of the catheter access site, which is typically located in the right femoral vein situated in the groin area. To ensure patient comfort, a local anesthetic is administered to numb the area before a small incision is made. A needle is then inserted into the blood vessel, followed by the placement of a sheath to facilitate the introduction of a guidewire. This guidewire is carefully threaded through the venous system, passing through the femoral vein, external iliac vein, and inferior vena cava, ultimately reaching the right atrium of the heart. Once the guidewire is in place, a catheter is advanced over it into the inferior vena cava and subsequently into the right atrium, right ventricle, and pulmonary arteries. During this journey, the catheter allows for direct visualization of the right heart chambers, enabling the evaluation of any congenital cardiac anomalies present. Additionally, critical measurements such as blood pressure in the right atrium and ventricle are obtained, and oxygen saturation levels are assessed to provide further insight into the patient's cardiac function. The tricuspid and pulmonary valves are also inspected for any abnormalities. In some cases, a separately reportable angiogram of the right heart and/or pulmonary arteries may be performed to obtain detailed images of the vascular structures. Upon completion of the procedure, the catheter is carefully withdrawn, and compression is applied to the venous access site to prevent bleeding, followed by the application of a dressing to ensure proper healing.
