We assessed the hemodynamic significance of a left internal mammary artery (LIMA) graft-pulmonary artery (PA) fistula in a post-bypass patient with chest pain. A Doppler-tipped guide wire and quantitative coronary angiography (QCA) were used to demonstrate that flow through the proximal LIMA (14.0 ml/min) was similar to the distal LIMA's contribution of flow to the left anterior descending artery (LAD) (15.6 ml/min), suggesting that the fistula was not hemodynamically significant. Therefore, intravascular Doppler and quantitative angiography may be used to assess the hemodynamic significance of a LIMA-PA fistula in a post-bypass patient.
我们评估了一名体外循环后胸痛患者左乳内动脉（LIMA）移植血管-肺动脉（PA）瘘的血流动力学意义。使用带有多普勒探头的导丝和定量冠状动脉造影（QCA）来证明，通过LIMA近端的血流量（14.0毫升/分钟）与LIMA远端向左前降支动脉（LAD）供血的血流量（15.6毫升/分钟）相似，这表明该瘘在血流动力学上无显著意义。因此，血管内多普勒和定量血管造影可用于评估体外循环后患者LIMA-PA瘘的血流动力学意义。
