It was reported that stent thrombosis, myocardial infarction, cardiogenic shock, and cardiac arrest occurred.The multivessel percutaneous coronary intervention (pci) was performed with multiple stenosis to the left anterior descending (lad) artery, first diagonal branch (d1) and second obtuse marginal branch (om2).A pci was performed on the 80% stenosed, 20mm long, target lesion between the proximal lad to mid lad.A non-bsc wire passed through the lesion, angioplasty was performed using a 2.25mm x 15mm nc emerge balloon catheter at 14 atmospheres for 15 seconds.However, the balloon ruptured and got separated.The physician deployed the 2.75mm x 32mm synergy drug-eluting stent to the affected area.Post-stent angioplasty was performed using a 3.00mm x 15mm nc emerge at 18 atmospheres for 10 seconds, but the balloon got stuck on the wire.Another non-bsc balloon was used for angioplasty.The stent became thrombosed and was treated with angioplasty and a 2.5mm x 28mm synergy drug-eluting stent deployed to overlap the first placed stent.Angioplasty was performed using a non-bsc balloon.There was a 0% residual stenosis post intervention.A pci was performed on the 90% stenosed target lesion located in the ostial first diagonal to the first diagonal branch (d1).A non-bsc wire passed through the lesion.Angioplasty was performed using a non-bsc balloon.A 2.25mm x 15mm nc emerge balloon catheter was advanced for dilatation at 18 atmospheres for 10 seconds.A 2.25mm x 38mm synergy drug-eluting stent drug-eluting stent was successfully placed.Post-stent angioplasty was performed using a non-bsc balloon.The stent became thrombosed intraprocedure.Angioplasty was performed with a 2.0 x 12mm emerge balloon at 10 atmospheres for 12 seconds and a non-bsc balloon.The stent thrombosis was treated with balloon angioplasty.There was 0% residual stenosis post intervention.A pci was performed on the 95% stenosed target lesion located in the ostial om2 to om2 lesion.A non-bsc wire passed through lesion.The pre-interventional distal flow was normal (timi 3).Angioplasty were performed using a 2.25 x 15mm nc emerge balloon catheter at 10 atmospheres for 15 seconds and two non-bsc balloons.The shaft of the 2.25 nc emerge severed and was left in the patient's om2.Then a non-bsc stent was placed successfully.The post-interventional distal flow was decreased.There was a 99% residual stenosis post intervention.The multilevel pci to the lad, d1 and om2 was complicated by the balloon issues and lad stent thrombosis.Myocardial infarction, cardiogenic shock, and cardiac arrest were encountered.The cardiac arrest was treated with cardiopulmonary resuscitation (cpr), heart pump and extracorporeal membrane oxygenation (ecmo) and the patient was sent to the coronary care unit.Successful return of spontaneous circulation with ongoing ecmo support.There was pulmonary hemorrhage secondary to anticoagulation and cpr.
