Toronto, ON - To repair, replace, or leave it alone, that is the question. Although Shakespeare might not have asked it, many cardiac surgeons are, particularly when dealing with an asymptomatic patient with mitral-valve prolapse, a condition caused by the displacement of some portion of one or both leaflets into Butterfly Valves the left atrium during systole. A clinical vignette, written by Drs Subodh Verma (St Michael's Hospital, Toronto, ON) and Thierry Mesana (Ottawa Heart Institute, ON), appearing in the December 3, 2009 issue of the New England Journal of Medicine, discusses the case of a 55-year-old man without symptoms shown to have mitral regurgitation caused by mitral-valve prolapse of the posterior leaflet [1]. The case highlights a challenge facing cardiac surgeons with patients with mitral-valve prolapse, some of whom have severe mitral regurgitation Plug Valves but no symptoms. For Verma and Mesana, the mitral-valve should be repaired, not replaced, but only by an experienced operator. The decision is based on a class IIa recommendation from the American College of Cardiology (ACC) and the American Heart Association (AHA). The vignette is used to discuss the effects of therapy, clinical use and evidence, areas of uncertainty, and current recommendations. "The report brings up two issues," Verma told heartwire. "What is the best approach for dealing with mitral-valve prolapse resulting in severe Balance valves mitral regurgitation? Should the strategy be to replace the valve or repair the valve? The second issue it brings up is with patients with severe mitral regurgitation who are asymptomatic: should they still be subjected to a mitral-valve-repair procedure, or should we wait until symptoms actually evolve?"

多伦多，开 - 修理，更换，或不管它，这就是问题。虽然莎士比亚可能不会要求，很多心脏外科医生，特别是在处理与二尖瓣脱垂，由某些部分位移造成的条件或无症状病人一进入左心房收缩时都传单。一名临床小品，由博士苏博德维尔马（圣迈克尔医院，多伦多，ON）和亨利Mesana（渥太华心脏研究所，ON）的编写，在2009年12月3号新英格兰医学杂志中出现的问题，讨论了案件今年55岁没有出现症状的人有二尖瓣关闭不全的二尖瓣，在后叶[1二尖瓣脱垂造成的]。案件突出了面临的挑战与二尖瓣脱垂的病人心脏外科医生，其中有一些严重的二尖瓣关闭不全，但没有症状。对于维尔马和Mesana，二尖瓣阀应进行维修，不更换，而只是由有经验的运营商。这项决定是基于第IIa类从美国心脏病学院（ACC）和美国心脏病协会（AHA）建议。该小品是用来讨论的治疗效果，临床使用和证据，模糊之处，目前的建议。 “这份报告带来了两个问题，”维尔马说心脏在线。 “什么是二尖瓣阀严重二尖瓣关闭不全造成脱垂问题的最佳办法？如果策略是替换或修理阀门阀门？的第二个问题是它带来了严重二尖瓣关闭不全谁是无症状：与病人应他们仍然受到一二尖瓣阀修复程序，还是应该等到症状，实际上演变？“
