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

A right heart catheterization is a specialized medical procedure performed to assess and diagnose congenital heart defects. 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, and a needle is inserted into the blood vessel, followed by the placement of a sheath to facilitate catheter insertion. A guidewire is then threaded through the venous system, allowing the catheter to be advanced into the right atrium, right ventricle, and pulmonary arteries. During the catheterization, the proceduralist inspects the right heart chambers and evaluates any congenital anomalies present. This includes measuring blood pressure within the right atrium and ventricle, as well as assessing oxygen levels. The tricuspid and pulmonary valves are also examined for any abnormalities. In cases where a detailed view of the heart's anatomy is required, a separately reportable angiogram may be performed to visualize the right heart chambers and pulmonary arteries. The procedure is particularly important for diagnosing congenital heart disease, as it helps identify both normal and abnormal connections between the heart chambers and great vessels. Normal connections allow for proper blood flow, while abnormal connections can lead to serious conditions such as cyanotic defects. Understanding these connections is crucial for determining the appropriate management and treatment of patients with congenital heart defects.
