((a)-(b)) Coronary angiography images of the patient in anterior-posterior cranial and lateral views which show myocardial bridges causing severe compression and near complete occlusion of the middle and distal segments of the LAD during systole, marked by arrows. ((c)-(d)) A drug eluting stent deployment at the middle segment of the LAD in lateral view. ((e)-(f)) During stenting of the distal segment of the LAD, coronary artery perforation occurred and massive blood flow extravasating into the pericardial space. ((g)-(h)) A polytetrafluoroethylene-covered stent was deployed over the perforation site, and this successfully sealed the perforation. LAD: left anterior descending.

During stenting of the bridged segment in the distal portion of the LAD with a 2.75 x 14 mm DES at 18 atmospheres, CP occurred and angiographic images showed massive and pulsatile extravasation from the LAD into the pericardial space (Figure 1).
