Figure 3From: Various clinical scenarios leading to development of the string sign of the internal thoracic artery after coronary bypass surgery: the role of competitive flow, a case series Pressure wire measurement of the left anterior descending artery: during the ic. injection of 100 μg of adenosine, only a nonsignificant translesional pressure gradient was provoked. The ratio of the pressure (FFR: fractional flow reserve) detected distally to the stenosis (green line) and the proximal (aortic) pressure (red line) was 0.83.Back to article page
