The VeriQ will display the Doppler spectrum at the default 5 seconds sweep rate as soon as a probe is connected, as shown in the figure. In Figures 1(a)-1(c) there is a flow-time curve of SVG to OM, SVG to PDA, and LIMA to LAD, respectively. After completion of all three grafts, there was good MGF in the arterial but not in the vein grafts. TTFM measurements with a mean arterial pressure of 80 mmHg were as follows: LIMA to LAD: MGF 83 ml/min and PI 1.4; LSV to OM: MGF 8 ml/min and PI 5.1; LSV to PDA: MGF 9 ml/min and PI 4.4 (Figures 1(a)-1(c)). An urgent angiography confirmed the patency of all three grafts with wide spread evidence of spasm to native coronary arteries (Figures 1(d)-1(i)). The arrows refer to spasm.
