CPT® Code 33418

The transcatheter mitral valve repair procedure, identified by CPT® Code 33418, is a minimally invasive technique aimed at addressing mitral valve regurgitation. This condition arises when the mitral valve's anterior and posterior leaflets do not close completely during ventricular systole, resulting in the backflow of blood into the left atrium. The procedure employs an edge-to-edge leaflet repair method, often utilizing a prosthesis such as the MitraClip, which is designed to enhance the physiological function of the mitral valve and significantly reduce regurgitation. The approach is percutaneous, meaning it is performed through the skin, and typically involves the use of fluoroscopy and transesophageal echocardiography (TEE) for guidance. This technique allows for the introduction of a steerable guide catheter into the vascular system, facilitating the repair process while minimizing the invasiveness of traditional surgical methods. The procedure is characterized by its ability to improve patient outcomes through a less traumatic approach, ultimately leading to better recovery times and reduced complications associated with open-heart surgery.
