CPT® Code 33465

The procedure described by CPT® Code 33465 involves the surgical replacement of the tricuspid valve, which is a critical component of the heart located between the right atrium and the right ventricle. This procedure is performed using cardiopulmonary bypass, a technique that temporarily takes over the function of the heart and lungs during surgery, allowing the surgeon to operate on a still and bloodless field. The need for a tricuspid valve replacement arises primarily from conditions such as tricuspid valve regurgitation, insufficiency, or incompetence, where the valve fails to close properly, leading to backward flow of blood. This can result in various complications, including heart failure and other serious cardiovascular issues. During the procedure, the surgeon may opt for either a mechanical valve, which is made from durable materials like metal and pyrolytic carbon, or a biological valve, which is derived from animal tissues, such as porcine valves. The choice of valve type depends on various factors, including the patient's condition and preferences. The surgical approach typically involves a median sternotomy, which is an incision made along the sternum to access the heart. Once the heart is accessed and cardiopulmonary bypass is initiated, the damaged tricuspid valve is excised and replaced with the artificial valve, which is then secured in place. The procedure concludes with the heart being closed and the patient gradually taken off the bypass machine, ensuring that the new valve functions correctly before completing the surgery.
