Current surgical management of restrictive ischaemic mitral regurgitation (IMR) includes mitral valve annuloplasty (MVA) using an undersized ring when the mechanism is secondary to leaflet restriction. In our experience, MVA alone is inadequate to eliminate mitral incompetence in these patients. We report the 'Down-Under Repair' as an adjunctive concept for the treatment of a subset of patients with restrictive IMR and associated inferobasal left ventricular aneurysm. The 'Down-Under Repair' reduces mitral leaflet restriction by approximating the origin of the posterior papillary muscle towards the mitral annulus. Midterm results demonstrated sustained valvular competence and symptomatic improvement.
目前，对于限制型缺血性二尖瓣反流（IMR）的外科治疗包括在瓣叶限制导致机制的情况下使用小环进行二尖瓣环成形术（MVA）。根据我们的经验，对于这些患者，单独进行 MVA 不足以消除二尖瓣关闭不全。我们报告了“澳大利亚下修复术”作为治疗具有限制型 IMR 和相关下壁左心室瘤的亚组患者的辅助概念。“澳大利亚下修复术”通过使后乳头肌的起源靠近二尖瓣环来减少二尖瓣瓣叶的限制。中期结果显示瓣膜功能持续良好，症状改善。
