Caval-Aortic Access to Allow Transcatheter Aortic Valve Replacement in Patients Otherwise Ineligible: Initial Human Experience

Objectives We describe the first use of caval-aortic access and closure to enable transcatheter aortic valve replacement (TAVR) in patients who lacked other access options. Caval-aortic access refers to percutaneous entry into the abdominal aorta from the femoral vein through the adjoining inferior vena cava.
