Figure 6 Bifurcation Stenting of a UPLM 5 Months Earlier
Follow-up angiography (left), when viewed in the left anterior oblique and caudal projection, showed the appearance of an important stenosis at the circumflex ostium. However, intravascular ultrasound (right) showed no important stenosis and no neointimal hyperplasia, but instead, an eccentrically expanded stent (arrows). The patient was asymptomatic with a fractional flow reserve after intracoronary adenosine of 0.92. This pseudostenosis in this asymptomatic patient was not treated.
