CPT® Code 0805T

Transcatheter superior and inferior vena cava prosthetic valve implantation (ie, caval valve implantation [CAVI]); percutaneous femoral vein approach

The procedure described by CPT® Code 0805T involves the implantation of a prosthetic valve in the superior and inferior vena cava, specifically referred to as caval valve implantation (CAVI). This intervention is primarily indicated for patients suffering from heart failure that is associated with severe tricuspid valve regurgitation. The procedure is performed using a percutaneous approach, which means that access to the femoral veins is achieved through the skin without the need for large incisions. This minimally invasive technique allows for the introduction of specialized instruments and devices necessary for the valve implantation. The use of the femoral veins, both left and right, facilitates the navigation of catheters and delivery systems to the heart's right atrium and the superior vena cava (SVC). The careful positioning and deployment of the prosthetic valve are critical to ensure proper function and to avoid complications, such as obstruction of the hepatic vein. The procedure is guided by imaging techniques, including fluoroscopy and echocardiography, to confirm the correct placement of the valve within the vascular structures. Overall, this advanced procedure aims to improve hemodynamics and alleviate symptoms associated with tricuspid valve dysfunction in patients with significant heart failure.
