Percutaneous valve therapy is said to be the last frontier in interventional cardiology. Over the past few years the work of decades has come to fruition. The first percutaneous implantation of a cardiac stent-valve in a human was reported by Bonhoeffer and colleagues in 2000. The first percutaneous aortic valve placement was performed by Cribier in 2002 using an antegrade approach in a patient with critical aortic stenosis. Attempts at percutaneous mitral valve repair are as varied as the pathophysiological mechanisms of mitral regurgitation. We are now embarking on a new era in the treatment of valvular heart disease with the introduction of percutaneous and minimally invasive devices and techniques to address valve dysfunction without conventional surgical repair/replacement. Pathology of all four cardiac valves has now been treated in early stage clinical feasibility (pilot) trials. There are at least 30 percutaneous valve programs currently being developed by 24 different companies. Two of the percutaneous aortic valve devices and five of the mitral valve devices are in various stages of clinical trials, ranging from feasibility to pivotal at the present time. Large-scale trials comparing percutaneous valve replacement and repair with surgery are just beginning. In this article we will look at the various technologies and advances in percutaneous valve replacement and repair, with an emphasis on those devices that are currently being utilized in the clinical realm.
经皮瓣膜治疗据说是介入心脏病学的最后一个前沿领域。在过去几年里,几十年的工作取得了成果。2000年,Bonhoeffer及其同事报道了首例人类心脏支架瓣膜的经皮植入。2002年,Cribier采用顺行途径为一名严重主动脉瓣狭窄患者进行了首例经皮主动脉瓣置换。经皮二尖瓣修复的尝试与二尖瓣反流的病理生理机制一样多种多样。随着经皮和微创设备及技术的引入,我们现在正开启瓣膜性心脏病治疗的新时代,无需传统手术修复/置换即可解决瓣膜功能障碍。目前,在早期临床可行性(试点)试验中已对所有四个心脏瓣膜的病变进行了治疗。目前有24家不同公司正在开发至少30个经皮瓣膜项目。其中两种经皮主动脉瓣装置和五种二尖瓣装置正处于临床试验的不同阶段,从可行性试验到关键试验都有。比较经皮瓣膜置换和修复与手术的大规模试验才刚刚开始。在本文中,我们将探讨经皮瓣膜置换和修复的各种技术及进展,重点关注目前临床领域正在使用的那些装置。
