I n this issue of the Journal, Zack et al. (1) at the Mayo Clinic report their investigation of the nationwide trends in prevalence and outcomes of isolated tricuspid valve (TV) surgery. Using ICD-9 codes, the authors identified all adult patients in the National Inpatient Sample who underwent TV surgery from 2004 to 2013. To focus primarily on isolated TV surgery, the authors excluded all patients with congenital heart disease, endocarditis, other associated valve surgery, cardiac transplantation, ventricular assist devices, or other cardiac surgery (except coronary artery bypass graft [CABG]). The exclusions eliminated 88% of patients who had TV surgical intervention, so this report describes a very narrowly defined patient population who only had TV surgery and may or may not have had CABG at the same time.

隔离三尖瓣手术*

在本期杂志中，Zack 等人。(1) 在梅奥诊所报告了他们对孤立三尖瓣 (TV) 手术的流行和结果的全国趋势的调查。使用 ICD-9 代码，作者确定了 2004 年至 2013 年接受 TV 手术的全国住院患者样本中的所有成年患者。 为了主要关注孤立 TV 手术，作者排除了所有患有先天性心脏病、心内膜炎和其他相关瓣膜手术的患者、心脏移植、心室辅助装置或其他心脏手术（冠状动脉旁路移植术 [CABG] 除外）。排除排除了 88% 接受过 TV 手术干预的患者，因此本报告描述了一个非常狭窄的患者群体，他们只接受过 TV 手术并且可能同时也可能没有接受过 CABG。
