Right heart catheterization for congenital heart defect(s) including imaging guidance by the proceduralist to advance the catheter to the target zone; normal native connections

A right heart catheterization is a specialized medical procedure performed to assess and diagnose congenital heart defects in patients. This procedure involves the insertion of a catheter into the right side of the heart to evaluate the structure and function of the heart chambers and associated blood vessels. The process begins with the preparation of the catheter access site, typically located in the right femoral vein in the groin area. After cleansing the skin, a local anesthetic is administered to minimize discomfort. A small incision is made, allowing for the insertion of a needle into the blood vessel, followed by the placement of a sheath to facilitate catheter insertion. The catheter is guided through the venous system, traversing the femoral vein, external iliac vein, and inferior vena cava, ultimately reaching the right atrium. Once in position, the catheter is advanced into the right ventricle and subsequently into the pulmonary arteries. During this journey, the proceduralist inspects the right heart chambers and evaluates any congenital anomalies present. Key measurements, such as blood pressure in the right atrium and ventricle, as well as oxygen saturation levels, are obtained to provide critical information regarding the patient's cardiac function. The procedure also includes a thorough examination of the tricuspid and pulmonary valves for any abnormalities. In some cases, a separate angiogram may be performed to visualize the right heart chambers and pulmonary arteries more clearly. It is important to note that even when congenital anomalies are present, the procedure is classified as right heart catheterization, as the catheter is still navigating the right side of the heart. Understanding the connections between the cardiac chambers and great vessels is essential for diagnosing congenital heart disease, as normal connections facilitate expected blood flow patterns, while abnormal connections can lead to significant clinical implications.
