Part of the ongoing argument concerning patient-prosthesis mismatch (PPM) following aortic valve replacement (AVR) is due to the perception that aortic annulus enlargement procedures increase the risk and technical difficulty of aortic valve surgery. Here, an aortic root reconstruction that involves enlargement of the annulus and tailoring of the aortic root to accommodate larger stented prostheses is presented that has been personally performed in 196 patients with no technique-related surgical deaths or complications, and thus can be carried out without additional risk. This aortic root enlargement aortoplasty and annuloplasty method can be calibrated to all AVRs involving stented manufactured prostheses when these are deemed the prosthesis of choice for the patient with a relatively small annulus and/or aortic root, severe left ventricular hypertrophy, compromised LV function or a very active lifestyle, to achieve predicted EOA values > or = 1.00 cm2/m2.
关于主动脉瓣置换术(AVR)后患者-假体不匹配(PPM)的持续争论部分源于一种观念,即主动脉瓣环扩大手术会增加主动脉瓣手术的风险和技术难度。在此,介绍一种主动脉根部重建方法,该方法涉及扩大瓣环并对主动脉根部进行修整以容纳更大的带支架假体,本人已对196例患者实施了该手术,无技术相关的手术死亡或并发症,因此可以在不增加额外风险的情况下进行。当对于瓣环和/或主动脉根部相对较小、严重左心室肥厚、左心室功能受损或生活方式非常活跃的患者,这些带支架的人工假体被认为是首选假体时,这种主动脉根部扩大主动脉成形术和瓣环成形术方法可适用于所有涉及带支架人工假体的AVR,以实现预测的有效开口面积(EOA)值≥1.00 cm2/m2。
