Initial Experience With Transcatheter Aortic Valve Implantation in Montenegro

Background: Transcatheter aortic valve implantation (TAVI) has emerged as an alternative treatment to classic aortic valve replacement(cAVR) for selected, high risk patients with severe aortic stenosis. Objectives: In our study, we compared preoperative parameters and postoperative outcomes in patients with TAVI and classic aortic valvereplacement. Patients and Methods: From March 2011 to December 2013, 18 patients received TAVI and 143 patients underwent cAVR. We comparedpreoperative Euro SCORE, 30 day mortality, complications after six month and echocardiography findings. Results: Patients received TAVI were older than patients underwent cAVR (72.7 ± 2.7: 65.3 ± 2.9; P < 0.001). Euro SCORE was higher in TAVIgroup (8.0%: 5.6%; P = 0.43). There were no statistically significant differences in 30-day (0.0%: 2.8%; P = 0.932) and 6-month mortality (5.5%:3.5%; P = 0.822) as well in stroke incidence (11.1%: 2.8%; P = 0.822). Pacemaker implantation is more frequent in TAVI than in cAVR group (22.0%:2, 1%; P < 0.001). Conclusions: High risk patients needing AVR are optimal candidates for transcatheter aortic valve implantation. TAVI is a valuablesolution for high risk patients needing AVR. Obtained results are comparable to results in transthoracic AVR in standard candidates foraortic valve implantation.
