| Summary: | Background: Aortic valve stenosis remains the most prevalent valvular pathology in Western countries. Rapid deployment bioprosthesis (RD) has emerged as a promising alternative to conventional valves for surgical aortic valve replacement (SAVR), particularly in elderly and high-risk patients. This study reports the short- and long-term outcomes of RD in patients with isolated aortic stenosis. Methods: A retrospective single-center analysis was conducted on 382 patients who underwent RD-AVR between 2014 and 2020. Data were collected from clinical files and national electronic databases. Primary outcomes included cardiopulmonary bypass (CPB) and cross-clamping (XC) times, postoperative complications, and long-term survival. Results: The mean age was 75.6 ± 5.9 years, with 29.8% of patients over 80 years old and a mean EuroSCORE II of 2.3 ± 1.5%. CPB and XC times were 36.7 ± 10.8 and 27.4 ± 8.1 min, respectively. Postoperative complications included acute kidney injury (AKI, 53.4%), de novo atrial fibrillation (31.9%), and high-grade/complete atrioventricular block with permanent pacemaker implantation (9.8%). In-hospital and 30-day mortality was 1.02% and 2.3%, respectively. The 5-year survival rate was 77%. At 6 months postoperatively, the mean transvalvular gradient was 11.1 ± 4.7 mmHg. At a median follow-up of 6.7 years, no cases of structural valve deterioration and only one case of endocarditis were reported. Conclusion: In this single-center study, RD in isolated AVR demonstrated favorable short- and long-term outcomes, including no structural valve deterioration at mid-term follow-up. These devices offer a safe and effective alternative to conventional SAVR, particularly in high-risk populations. |
