(A) The angiogram shows total occlusion of the left anterior descending (LAD) artery (the arrow shows the level of occluded area). (B) The angiogram after deploying stents in the LAD (the arrows show coronary stents).

Ticagrelor and 300 mg chewable aspirin were administered, and the patient was taken to the catheter laboratory for primary PCI. The coronary angiogram showed the total occlusion of the anterior descending (LAD) artery at the level of the diagonal artery (Fig. 1A and Video 1). After percutaneous transluminal coronary angioplasty, 3.0 x 33 mm, and 3.0 x 20 mm drug-eluting stents were deployed in telescopic fashion (Fig. 1B and Video 2).
TThe angiogram revealed the coronary artery perforation (the arrow shows the spilling into the chamber).

After percutaneous transluminal coronary angioplasty, 3.0 x 33 mm, and 3.0 x 20 mm drug-eluting stents were deployed in telescopic fashion (Fig. 1B and Video 2). After then, the type 3 LAD coronary perforation was seen in the control angiogram (Fig. 2 and Video 3).
(A) The coronary balloon was inflated at the proximal LAD immediately. (B) The angiogram after deploying covered stent shows no leakage in the LAD.
