Figure 1 Images of case 1.
A: Angiography showed 85% stenosis at the distal end of the anastomosis of the left internal mammary artery (LIMA)-left anterior descending artery graft (orange arrow); B: Before intervention, the fractional flow reserve measured via the LIMA was 0.75 (positive); C: Dilation with a 2.0 mm × 31.0 mm drug containing balloon was performed at the stenotic segment of the left anterior descending artery via the LIMA (orange arrow); D: After balloon dilation, remeasurement of pressure showed that the fractional flow reserve was 0.94.
Figure 2 Images of case 2.
A: Angiography indicated 75% anastomotic stenosis (orange arrow); B: The fractional flow reserve measured from the left internal mammary artery to the distal end of the anastomosis was 0.83 (negative).
