The early and late results after transcatheter aortic valve implantation in our center

Background:The early and late term results of who underwent transcatheter aortic valve implantation (TAVI) in our center were evaluated in this study. Methods: The early and late term results of 16 patients with severe aortic stenosis who underwent the TAVI procedure in our clinic between 2012 and 2013 years were evaluated. All of our patients were implanted with CoreValve bioprosthetic valves through the transfemoral approach and followed-up for 16.2±14.7 months. Results: Before the procedure, the mean aortic valve area (AVA) was 0.7±0.2cm2, the mean valvular gradients (MnG) were 55.6±19.7 mmHg and the mean functional class was 2.9±0.2. Following the TAVI procedure the AVA, MnG ve functional class were improved, significantly. The technical success rate was %87.5, and mean 1.3±0.6 valves was implanted in all patients. Surgical AVR was required for 1 patient because of severe paravalvular leakage. At the procedure, in 1 patient third degree atrioventricular (AV) block and in 1 patient coronary occlusion were developped. The patient with third degree AV block was required permanent pacemaker. In the early term after TAVI in 1 patient transient ischemic attack and in 2 patients minors hemoragy were developped. 1 patient was dead of cardiac tamponade in the procedure, 1 patient was dead from infections and dissemine intravascular coagulopathy postoperative 33th days and 2 patients were dead of noncardiac reasons on the 7th and 15th months, respectively. In this study 3 years survi of TAVI procedure was %75. Conclusion: In the patients with high surgery risk or inoperable aortic stenosis, TAVI is a rather safe and successful method in the early and late terms as an alternative therapy to surgery.
