BACKGROUND: Few data exist on the clinical impact of transcatheter aortic valve implantation (TAVI) in patients with symptomatic aortic stenosis and a high surgical risk. The aim of this study was to determine the survival and the factors predicting mortality after 30 days post-TAVI with the CoreValve prosthesis (Medtronic, Minneapolis, MN).
METHODS: From April 2008 to October 2010, the CoreValve prosthesis (Medtronic) was implanted in 133 consecutive high-risk surgical patients with symptomatic severe aortic stenosis.
RESULTS: The mean age was 79.5 ± 6.7 years. The logistic European System for Cardiac Operative Risk Evaluation was 21.5% ± 14%. The implantation success rate was 97.7%. In-hospital mortality was 4.5%, and the combined end point of death, vascular complications, myocardial infarction, or stroke had a rate of 9%. Survival at 12 and 24 months was 84.5% and 79%, respectively, after a mean follow-up of 11.3 ± 8 months. The New York Heart Association functional class improved from 3.3 ± 0.5 to 1.18 ± 0.4 and remained stable at 1 year. A high Charlson index (hazard ratio [HR] 1.44, 95% CI 1.09-1.89, P < .01) and a worse Karnofsky score before the procedure (HR 0.95, 95% CI 0.92-0.99, P = .021) were predictors of mortality after 30 days.
CONCLUSIONS: Transcatheter aortic valve implantation with the CoreValve prosthesis for patients with aortic stenosis and a high surgical risk is a safe, efficient option resulting in a medium-term clinical improvement. Survival during follow-up depends on the associated comorbidities. Early mortality beyond 30 days is predicted by preoperative comorbidity scores and the functional status of the patient.
