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

A combined right heart and left heart catheterization is a specialized procedure performed on patients diagnosed with congenital heart defects. This procedure involves the insertion of catheters into both the right and left sides of the heart to assess and evaluate the heart's structure and function. The process begins with the cleansing of the skin over the catheter access sites to minimize the risk of infection. For the right heart catheterization, the most common access point is the right femoral vein located in the groin area. A small incision is made to facilitate the insertion of a needle into the vein, followed by the placement of a sheath to allow for the passage of a guidewire. The guidewire is carefully threaded through the venous system, navigating through the femoral vein, external iliac vein, inferior vena cava, and into the right atrium. Once the guidewire is in place, a catheter is advanced over it into the right atrium, right ventricle, and pulmonary arteries. This allows for direct inspection of the right heart chambers, where blood pressure and oxygen levels are measured, and the tricuspid and pulmonary valves are evaluated. The procedure may also include a separately reportable angiogram of the right heart and/or pulmonary arteries to visualize any abnormalities. In addition to the right heart catheterization, a retrograde left heart catheterization is performed. This involves accessing the left side of the heart through the brachial, axillary, or femoral artery. After prepping the skin, the artery is punctured, and a sheath is placed. A guidewire is then inserted and threaded retrograde through the artery into the aorta, left ventricle, and left atrium. The catheter is positioned in the left heart, allowing for the assessment of the aortic valve, left ventricle, mitral valve, and left atrium, as well as the evaluation of any congenital anomalies present in these structures. Throughout the procedure, pressures within the left ventricle and atrium are measured, along with pressure gradients across the aortic and mitral valves. The procedure may also involve positioning the catheter in the right and left coronary arteries to assess any vascular anomalies. Upon completion of the catheterization, the catheters are withdrawn, and compression dressings are applied to the access sites. It is important to report the appropriate CPT® code based on the presence of abnormal connections, as this significantly impacts the management of congenital heart defects.
