Task: Question Generation
Input (English): The novel ACURATE TA™ transcatheter aortic valve (Symetis, Ecublens, Switzerland) is composed of a self-expanding nitinol stent covered by an anti-paravalvular leak skirt designed for transapical implantation. Since Conformite Europeenne (CE)-mark approval, the first 250 patients implanted with the newly approved device have been included in this post-market, multicentre registry.', 'The registry was conducted at 17 sites in Germany, Italy, Switzerland and Argentina to treat 250 high-risk elderly patients. This all-comers population presented preoperatively with a mean aortic gradient of 43.2 ± 17.4 mmHg, mean age of 80.9 ± 6.3 years, mean society of thoracic surgeons risk score of 8.0 ± 5.9% and mean logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) I of 22.3 ± 12.7%. The majority of patients (93%) were in New York Heart Association (NYHA) class III/IV. All patients were treated within a multidisciplinary Heart Team.', 'The procedural success rate was 98% (n = 245) with two valve-in-valve procedures and three conversions to conventional surgery. The 30-day mortality rate was 6.8%. Postimplant echocardiography revealed a relevant paravalvular leak (moderate 2+) in 2.3% of patients, with all other patients demonstrating either none/trace or a 1+ leak. The 30-day stroke rate was 2.8% and the mean transvalvular gradient was 12.4 ± 5.8 mmHg. A new pacemaker implantation was required in 10.0% of patients and 85% of patients returning for the follow-up presented in NYHA class I/II.
Output (English): Does first registry result from the newly approved ACURATE TA™ TAVI system†?
