Successful Percutaneous Balloon Angioplasty in a Patient Presenting With STEMI and Acute Intracranial Hemorrhage

Percutaneous coronary interventions (PCI) mandates the administration of anti-platelet and anti-thrombotic agents to prevent intracoronary and post-procedural thrombosis upon introducing thrombogenic foreign bodies such as intracoronary wires, balloons, or stents, especially in the setting of acute coronary syndrome (ACS) given the hypercoagulable state associated with it. This is a case of a 54-year-old female who presented to the emergency department with left-sided weakness and dysarthria for an unknown duration. A CT scan of the head showed acute right middle cerebral artery distribution infarct. She subsequently underwent a successful thrombectomy. Four hours later, the patient became lethargic and nauseous. Electrocardiogram showed anterior wall ST elevation with new-onset anterior wall akinesia on transthoracic echocardiogram. Repeat CT of the head showed acute intracranial hemorrhagic conversion. She then developed cardiac arrest mandating emergent cardiac catheterization. Coronary angiogram revealed 100% occlusion in a mid left anterior descending artery (LAD) and 80% in a left circumflex artery (LCX) and chronic total occlusion of the right coronary artery (RCA). After weighing risks and benefits, PCI was performed with rapid plain old balloon angioplasty (POBA) to the 100% thrombotic lesion in the LAD with successful restoration of flow without administering anti-platelet or anti-thrombotic agents given the acute intracranial hemorrhage, She was then discharged to a rehab facility a few days later in stable condition. This case demonstrates successful percutaneous coronary intervention in the 100% occluded LAD in a life-threatening situation despite not using anticoagulation or antiplatelet therapy due to active intracranial hemorrhage.
