摘要

分数血流储备(FFR)评价中左主干冠状动脉(LMCA)狭窄已在临床决策中得到验证。然而，放置FFR换能器的子血管的大小及其所覆盖的心肌的数量却很少受到关注。我们报告了一个病例，证明了传感器位置、子血管大小和支撑心肌数量在评估LMCA狭窄中的重要性，并指出了潜在的缺陷。

Evaluating Equivocal Left Main Stenosis with Fractional Flow Reserve - Not all Daughter Vessels are Created Equally.

Fractional flow reserve (FFR) evaluation of intermediate left main coronary artery (LMCA) stenosis has been validated in clinical decision-making. However, the size of the daughter vessel, in which the FFR transducer is placed and the amount of myocardium it subtends, has received less attention. We present a case that demonstrates the importance of transducer location, size of the daughter vessel and the amount of subtended myocardium in evaluation of LMCA stenosis, pointing out potential pitfalls.
