| الوصف: | Background: Surgical aortic valve replacement with rapid deployment bioprosthesis guarantees good hemodynamic results but carries the risk of paravalvular leaks. To address this issue, an annulus stabilization technique has been recently developed. Methods: Clinical and hemodynamic parameters from patients treated for aortic valve replacement with the rapid deployment bioprosthesis and a concomitant annulus stabilization technique were prospectively collected and retrospectively analyzed. Echocardiographic data at discharge and at 1-year follow-up were collected and analysed. Results: A total of 57 patients (mean age 74.3 ± 6.1 years) with symptomatic aortic valve stenosis underwent aortic valve replacement with the rapid deployment bioprosthesis and concomitant annulus stabilization technique (mean valve size: 23.8 ± 1.9 mm). Combined procedures accounted for 56.1%. Hospital mortality was 1.8% and a new pacemaker for conduction abnormalities was implanted in 10 patients. The pre-discharge echocardiographic control showed absence of paravalvular leaks of any degree in all patients with mean valve gradient of 9.6 ± 4.0 mmHg. The 1-year echocardiographic control confirmed the good valve hemodynamic (mean gradient of 8.0 ± 2.8 mmHg) and absence of leaks. Conclusion: In this preliminary clinical experience, the annulus stabilization technique prevents postoperative paravalvular leaks after rapid deployment aortic valve implantation, up to 1-year postoperatively. Studies on larger series are of paramount importance to confirm the long-term efficacy of this new surgical technique. |
