Post-surgical deterioration of mitral valve repairs or replacements may present a clinical dilemma due to the high-risk nature of repeat surgery. Recent advances in transcatheter techniques and surgery have enabled the implantation of balloon-expandable valves in the mitral position when surgical rings and valves are present. Valves may be implanted either via transseptal or transapical access, with a reported success rate between 88-100 %.
二尖瓣修复或置换术后的病情恶化可能会带来临床困境，因为再次手术具有高风险。导管技术和外科手术的最新进展使得在已有外科环和瓣膜的情况下能够在二尖瓣位置植入球囊扩张瓣膜。瓣膜可通过经房间隔或经心尖途径植入，报道的成功率在88%至100%之间。
