It was reported the procedure was to treat an eccentric lesion with heavy calcification in the proximal to mid right coronary artery.A 4.0 x 38 mm xience stent was successfully deployed in the more distal segment of the long mid lesion and then the rest of the lesion was covered with a 4.0 x 12 mm xience stent, overlapping the previously deployed stent.Post-dilatation of the middle segment was performed using the stent delivery balloon, but subsequent angiography showed a severe eccentric coronary rupture.The physician commented that the perforation did not occur because of the stents, but because of the calcification and frailty of the vessel.The patient did have significant chest discomfort.A 4.0 mm non-compliant (nc) balloon was inflated across the lesion for tamponade purposes with significant improvement after several inflations.An emergent echocardiogram revealed a moderate concentric pericardial effusion with tamponade features, accompanied by hypotension and requirement of medication.Therefore, a 3.5 x 19 mm graftmaster was used to cover the perforation successfully.Post-dilatation was performed with a 4.0 mm nc balloon.Angiography showed a seal of the perforation.A 4.0 x 8 mm xience was successfully deployed across the ostium and post-dilated.Then, pericardiocentesis was performed with dramatic and immediate response in blood pressure.Angiography revealed very good results with no residual stenosis with good timi 3 flow and no dissections or extravasation.No additional information was provided.
