Abstract
We present a case of angina, where extreme coronary tortuosity affected invasive physiology interpretation. Extreme coronary tortuosity may lower fractional flow reserve and instantaneous wave-free ratio. Therefore, invasive physiology can be misleading in this setting, when used to evaluate stenosis significance, or when used post-percutaneous coronary (PCI) intervention for physiology guided stent optimisation.
摘要
我们呈现了一例心绞痛病例，其中严重的冠状动脉迂曲影响了有创生理学的解读。严重的冠状动脉迂曲可能降低血流储备分数和瞬时无波比。因此，在评估狭窄严重程度时，或在经皮冠状动脉介入治疗（PCI）后进行生理学指导的支架优化时，有创生理学可能会产生误导。
