Introduction

30% of patients with severe symptomatic aortic stenosis do not undergo surgery for replacement of the aortic valve, owing to advanced age, left ventricular dysfunction, or the presence of multiple coexisting conditions. aortic-valve implantation (TAVI) has been suggested for high-risk patients with aortic stenosis. TAVI was performed for two patient with severe aortic stenosis in our clinic on November 2014.

Material-Methods

The patients are male. They are 73 and 76 years old. The patients had New York Heart Association (NYHA) class III symptoms. They were at high surgical risk, as defined by a Society of Thoracic Surgeons (STS) risk score of 10% or higher. The echocardiographic findings are in the following; ejection fraction(EF) 22% and 40%, aortic valve area (AVA) 0.6 and 0.7 cm2, mean aortic valve gradient 55 and 45 mm Hg, peak aortic-jet velocity 4.3 and 4.1 m/sn.

The Edwards SAPIEN heart-valve system (Edwards Lifesciences) consists of a trileaflet bovine pericardial valve and a balloon-expandable, stainless-steel support frame. The TAVI procedure was performed in the catheterization laboratory with the patient under general anesthesia.
