Primary percutaneous coronary intervention on split left coronary artery: Two case reports
Abstract
The split left coronary artery (LCA) is an anomaly of coronary arteries connection related to the aorta, presenting more often in patients who underwent invasive coronary angiography compared to coronary computed tomography angiography. Although this anomaly causes no hemodynamic impairment, failure to recognize may lead to incorrect diagnosis and prolonged procedures during acute myocardial infarction resulting in serious complications. We report 2 cases of split left coronary artery presenting with acute myocardial infarction who underwent primary percutaneous coronary interventions (pPCI) with excellent outcomes. In the both cases, electrocardiogram demonstrated ST-segment elevation and cardiac biomarkers were increased. Also, before coronary angiography in both patients echocardiographic examination was performed revealing hypokinesis who corresponded with the territory of occluded coronary arteries. During invasive further coronary examinations split left artery was found, besides the culprit lesion in the left anterior descending artery (LAD). Successful percutaneous stenting was performed on LAD achieving TIMI flow grade 3 in both cases. Prompt recognition of split LCA in the setting of acute myocardial infarction during pPCI, it is essential to achieve appropriate treatment and avoid potential clinical consequences.
