The patient with severe asymptomatic aortic stenosis presenting for elective noncardiac surgery poses a unique challenge. These patients are not traditionally offered surgical aortic valve replacement or transcatheter aortic valve replacement given their lack of symptoms; however, they are at increased risk for postsurgical complications given the severity of their aortic stenosis. The decision to proceed with elective noncardiac surgery should be based on individual and surgical risk factors. However, severity of aortic stenosis is not accounted for in current surgical risk factor assessment scoring; therefore, extensive communication with patients and surgical teams is necessary to minimize a patient's risk. A clear intraoperative plan should be designed to manage the unique hemodynamics of these patients, and a discussion should address postoperative placement.
对于接受择期非心脏手术的严重无症状主动脉瓣狭窄患者,这是一个独特的挑战。这些患者通常不接受主动脉瓣置换术或经导管主动脉瓣置换术,因为他们没有症状;然而,由于主动脉瓣狭窄的严重程度,他们在手术后出现并发症的风险增加。决定是否进行择期非心脏手术应基于个体和手术风险因素。然而,目前的手术风险因素评估评分并未考虑主动脉瓣狭窄的严重程度;因此,需要与患者和手术团队进行广泛的沟通,以最大限度地降低患者的风险。应设计明确的术中计划来管理这些患者的独特血液动力学,并且应该讨论术后的放置位置。
