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); normal native connections

A combined right heart and left heart catheterization is a diagnostic procedure performed on patients with congenital heart defects. This procedure involves the insertion of catheters into both the right and left sides of the heart to assess the structure and function of the heart chambers and valves. 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 typical 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 external iliac vein, inferior vena cava, and into the right atrium. Once the catheter is positioned within the right heart, various measurements, including blood pressure and oxygen levels, are taken, and the heart's anatomy is inspected. In addition to the right heart catheterization, a retrograde left heart catheterization is performed, typically through the brachial, axillary, or femoral artery. This involves puncturing the artery with a needle, placing a sheath, and threading a guidewire retrograde through the arterial system into the aorta and left heart chambers. The left heart structures, including the aortic valve, left ventricle, mitral valve, and left atrium, are evaluated for any congenital anomalies. Pressure measurements are also obtained across the aortic and mitral valves. The procedure may include additional imaging, such as a left ventriculogram or left atrial angiography, to provide further insight into the heart's condition. The entire process is crucial for diagnosing congenital heart defects, which can lead to significant complications if left untreated. The distinction between normal and abnormal connections in the heart is vital, as normal connections allow for proper blood flow, while abnormal connections can lead to serious conditions such as cyanotic defects.
