ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the safety and efficacy and summarize the initial experience of transcatheter aortic valve implantation (TAVI) for treating patients with severe aortic stenosis.</p><p><b>METHODS</b>From October 2010 to May 2011, TAVI using 18 F Corevalve system was applied in 3 patients with severe calcified aortic valve stenosis at high risk for surgery. The efficacy and complications of the procedure were analyzed and the procedure experiences were summarized.</p><p><b>RESULTS</b>TAVI procedure was successful in all 3 cases. The mean operation time was (109.0 ± 22.6) minutes and X-ray exposure time was (24.0 ± 9.5) minutes. The peak pressure gradients after surgery were significantly reduced [from (84 ± 15) mm Hg (1 mm Hg = 0.133 kPa) to (6 ± 3) mm Hg]. A trivial to mild paravalvular leak was observed in all patients post procedure. Case 1 was free from perioperative complications. Case 2 experienced a transient complete left bundle branch block. Case 3 developed 3 degree atrioventricular block and implanted with a permanent cardiac pacemaker, cardiac tamponade which was relieved through conservative treatment, including pericardial puncture and drainage and acute kidney injury.</p><p><b>CONCLUSIONS</b>Our initial experience showed that TAVI using the 18 F Corevalve system is safe and effective for patients with severe calcified aortic valve stenosis at high-risk for surgery, though the procedure may cause some complications. Strict patient selection and proficient surgical techniques may reduce the incidence of complications.</p>
