Objectives: We report on real-world safety and performance outcomes of minimally invasive rapid-deployment aortic valve replacement using the EDWARDS INTUITY Elite aortic valve system. Methods: The study valve system was used in a European, prospective, multicentre post-market study. Various procedural, haemodynamic and clinical outcomes were evaluated through 6 months of post-implant. Results: A total of 276 patients out of 280 (98.6%) enrolments were successfully implanted with the study valve using a minimally invasive approach between February 2016 and April 2017. Of these 276 patients, 240 (87%) underwent partial sternotomy and 36 (13%) patients underwent right thoracotomy. Mean cross-clamp time was 51.9 [standard deviation (SD): 16.0] min. From baseline to 6 months, the mean effective orifice area increased from 0.8 (SD: 0.3) to 1.8 (SD: 0.6) cm2 and the mean systolic gradient decreased from 46.0 (SD: 14.1) to 8.8 (SD: 3.7) mmHg. After 6 months, 70.7% and 26.4% of patients were in New York Heart Association class I and II, respectively. Freedom from death, major bleeding, major paravalvular leak, reoperation and device explant at 6 months were 96.0%, 98.5%, 98.8%, 99.2% and 99.2%, respectively. Conclusions: These results demonstrate that the study valve is a safe and effective choice for patients undergoing aortic valve replacement via minimally invasive surgery.
