We describe the rationale, methodology, and our preliminary experience with a new surgical technique for mitral valve replacement in patients with severe calcification of the mitral annulus in which the conventional techniques can not be applied. In contrast with other procedures published in the literature for these patients, in which the placement of the prosthesis is supra-annular, we plicate both mitral leaflets and the atrial wall creating a new annulus that allows the intra-annular placement of the prosthesis.
我们描述了一种用于二尖瓣环严重钙化且无法应用传统技术的患者进行二尖瓣置换的新手术技术的原理、方法及初步经验。与文献中报道的针对这些患者的其他手术方法不同，那些方法中人工瓣膜置于瓣环上方，而我们将二尖瓣叶和心房壁折叠起来，形成一个新的瓣环，从而能够将人工瓣膜置于瓣环内。
