Unloading and successful treatment with bioresorbable stents during percutaneous coronary intervention: A case report

Figure 1  Electrocardiogram examination on admission.

Figure 2 Preoperative images. Right coronary angiography (Left anterior position).

Figure 3 Preoperative images. A: Left coronary angiography (right shoulder position); B: Intravascular ultrasound (IVUS) of the proximal segments of the left anterior descending artery (LAD); C: IVUS of the middle segments of the LAD.

Figure 4 Intraoperative stent position. A: Angiography (right shoulder position) after balloon dilation of the proximal and middle segments of the left anterior descending artery; B: Angiography (spider position) Positioning of the second bioresorbable stents (BRS) after the first BRS implantation in the middle descending artery; C: Postoperative images after BRS in situ expansion from proximal segment to left main trunk in the right shoulder position.

Figure 5 Angiography (spider position). A: Imaging changes in the proximal segment of the left anterior descending artery; B: Intravascular ultrasound (IVUS) of the proximal end of the unloaded bioresorbable stents (BRS) stent; C: IVUS of the distal end of the unloaded BRS stent.

Figure 6 Postoperative images. A: After bioresorbable stents in situ expansion from proximal segment to left main trunk: In the spider position; B: Intravascular ultrasound of the proximal of left anterior descending artery after bioresorbable stents expansion: The minimum lumen area was 5.26 mm².
