Chordal Cutting: State of the Art

摘要: Ischemic mitral regurgitation (MR) is caused by altered left ventricular geometry and function (Otsuji et al., Circulation 96:1999–2008, 1997; Llaneras J Thorac Cardiovasc Surg 105:439–442, 1993; Komeda 113:292–300, 1997), doubles heart failure mortality after myocardial infarction (MI) (Grigioni 103:1759–1764, 2001). Still common despite improvement in revascularization medical treatment MI, its remains frustrating controversial (Wu Am Coll Cardiol 45:381–387, 2005; Matsuzaki Ann 90:788–794, 2010; McGee 128:916–924, 2004; Kuwahara 114:I529–I534, 2006; Hung 110:II85–II90, Guy 43:377–383, 2004). Restrictive annuloplasty, combined with coronary revascularization, currently the most commonly performed surgical procedure to treat chronic ischemic MR. However, variable results (Matsuzaki 2006), potentially induced stenosis high rate of MR recurrence this strategy (Hung 2004) suggest need for a new approach that addresses subvalvular valve apparatus (Szymanski Circulation. 126:2720–2727, 2012). Thus, benefit hotly debated would be difficult resolve so long as existing therapies are incompletely effective permanently abolishing New therapeutic opportunities perplexing their diversity we choose chapter describe chordal cutting technique which can achieve more solutions.
