Percutaneous Aortic Valve Replacement for Severe Aortic Stenosis in High-Risk Patients Using the Second- and Current Third-Generation Self-Expanding CoreValve Prosthesis
نویسنده
چکیده
Methods Patients with: 1) symptomatic, severe aortic valve stenosis (area 1 cm); 2) age 80 years with a logistic EuroSCORE 20% (21-F group) or age 75 years with a logistic EuroSCORE 15% (18-F group); or 3) age 65 years plus additional prespecified risk factors were included. Introduction of the 18-F device enabled the transition from a multidisciplinary approach involving general anesthesia, surgical cut-down, and cardiopulmonary bypass to a truly percutaneous approach under local anesthesia without hemodynamic support.
