Transcatheter aortic valve implantation in patients with high risk aortic stenosis a clinical follow up

OpenAlex İngilizce

Background: This study aims to evaluate early- and mid-term results of our patients who underwent transluminal aortic valve implantation (TAVI). Methods: The early- and mid-term results of 10 patients (7 females, 3 males; mean age 80.4±6.7 years; range 64 to 88 years) with high surgical risk who underwent the TAVI procedure in our clinic between January 2010 and April 2011 were evaluated. All of our patients were implanted with Edwards Sapien bioprosthetic valves through the transfemoral approach and followed-up for 6.1±5.2 months. Results: Before the procedure, the mean functional class was NYHA 3.8±0.4, the mean aortic valve area (AVA) was 0.6±0.1cm2, the left ventricular ejection fraction (LVEF) was %55.4±9.8 and the mean peak (PAG) and mean valvular gradients (MAG) were 94.3±24.2 and 54.5±17.7 mmHg, respectively. No additional interventional procedure was required during this stage. The technical success rate was 100%, and a single valve was implanted in all patients. Neither mortality nor major strokes were observed during the follow-up period. Following the TAVI procedure, the NYHA decreased to 1.9±0.6 (p
