Description
Background: Report of our single centre experiences with transcatheter aortic valve implantation (TAVI) in a group of high-risk patients without extracorporeal circulation. Methods: TAVI was performed via a left-sided small anterolateral minithoracotomy on the beating heart. A pericardial xenograft fixed within a stainless steel, balloon expandable stent (Edwards SAPIEN THV, Edwards Lifesciences) was implanted. Results: Twenty-two consecutive patients (80.3 a) were operated on from 11/09 until 12/10 using fluoroscopic and echocardiographic visualization. Average EuroSCORE and STS-score predicted risk for mortality was 24.8 ± 6.5 and 14.3 ± 4.5, respectively. Transapical valve positioning was performed successful in 22 patients, two required immediate conversion to sternotomy, because of coronary artery obstruction and severe aortic regurgitation. Echocardiography revealed minor paravalvular or central leakage in 8 patients. One patient died in-hospital on day 40. Actuarial survival was 95.5% at a follow-up interval of 223 days (range 19–391 days). Conclusions: TAVI can be performed safely with good results in selected high-risk patients. Long-term valve performance will need to be evaluated.
