Aortic valve replacement (AVR) in patients with a small aortic annulus is a challenging issue. The importance of prosthesis-patient mismatch (PPM) post aortic valve replacement (AVR) is controversial but has to be avoided. Many studies support the fact that PPM has a negative impact on short and long term survival. In order to avoid PPM, aortic root enlargement may be performed. Alternatively and keeping in mind that often some comorbidities are present in old patients with small aortic root, the Perceval S suturelles valve implantation could be a perfect solution. The Perceval sutureless bioprosthesis provides reasonable hemodynamic performance avoiding the PPM and providing the maximum of aortic orifice area. We would like to see in the near future the role of the aortic root enlargement techniques in the era of surgical implantation of the sutureless valve (SAVR) and the transcatheter valve implantation (TAVI).
对于主动脉瓣环较小的患者,主动脉瓣置换术(AVR)是一个具有挑战性的问题。主动脉瓣置换术后人工瓣膜-患者不匹配(PPM)的重要性存在争议,但必须避免。许多研究支持PPM对短期和长期生存有负面影响这一事实。为了避免PPM,可进行主动脉根部扩大术。另外,考虑到主动脉根部较小的老年患者通常存在一些合并症,Perceval S无缝合瓣膜植入可能是一个完美的解决方案。Perceval无缝合生物瓣膜具有合理的血流动力学性能,可避免PPM并提供最大的主动脉口面积。我们希望在不久的将来看到主动脉根部扩大技术在无缝合瓣膜外科植入(SAVR)和经导管瓣膜植入(TAVI)时代所起的作用。
