Transcatheter aortic valve replacement (TAVR/TAVI) with prosthetic valve; cardiopulmonary bypass support with percutaneous peripheral arterial and venous cannulation (eg, femoral vessels) (List separately in addition to code for primary procedure)

Transcatheter aortic valve replacement (TAVR/TAVI) is a minimally invasive procedure designed to treat aortic stenosis, a condition characterized by the narrowing of the aortic valve, which can lead to significant heart complications. During this procedure, a diseased aortic valve is replaced with a prosthetic valve, allowing for improved blood flow and heart function. The TAVR/TAVI procedure is particularly beneficial for patients who may be at high risk for traditional open-heart surgery due to age, comorbidities, or other health factors. When TAVR/TAVI is performed with the support of cardiopulmonary bypass (CPB), it involves the use of specialized cannulas to connect the patient’s vascular system to a heart-lung machine, which temporarily takes over the function of the heart and lungs during the procedure. This support is crucial for maintaining blood circulation and oxygenation while the aortic valve is being replaced. The use of percutaneous peripheral arterial and venous cannulation, typically through the femoral vessels, is a common approach to establish CPB, although alternative methods may be employed based on the patient's vascular anatomy. The procedure is complex and requires careful planning and execution to ensure patient safety and optimal outcomes.
