Coronary artery disease (CAD) and severe aortic stenosis (AS) often coexist. When significant coronary lesions were found in patients undergoing surgical aortic valve replacement, combined coronary artery bypass grafting was the gold standard of treatment. Differently, the management of concomitant CAD in patients who are candidates for transcatheter aortic valve implantation (TAVI) is a matter of debate. In this review, we discuss the evidence and present the current viewpoints regarding the definition and prognostic implications of CAD in patients undergoing TAVI and the potential role and limitations of invasive functional coronary stenosis assessment in severe AS. We present the challenges of percutaneous coronary intervention (PCI) in this setting, including timing of intervention, completeness of revascularization in the context of the complexity of the disease and the risk associated with the PCI procedure itself. Finally, we mention ongoing trials that should provide some long-awaited answers in this field.
冠状动脉疾病(CAD)与严重主动脉瓣狭窄(AS)常并存。在接受外科主动脉瓣置换术的患者中发现显著冠状动脉病变时,冠状动脉旁路移植术联合应用是治疗的金标准。不同的是,对于适合经导管主动脉瓣植入术(TAVI)的患者,其合并CAD的管理存在争议。在本综述中,我们讨论相关证据,并就TAVI患者CAD的定义及其预后意义,以及严重AS时有创功能性冠状动脉狭窄评估的潜在作用和局限性提出当前观点。我们阐述了在此情况下经皮冠状动脉介入治疗(PCI)面临的挑战,包括干预时机、鉴于疾病复杂性的血运重建完整性以及PCI手术本身相关风险。最后,我们提及了正在进行的试验,这些试验应能在该领域提供一些期待已久的答案。
