Non-selective Aortic Root Angiographic Contrast Injection in a Case of Anomalous Right Coronary Artery Ostium.

Anomalous origin of the right coronary artery (RCA) is a rare congenital cardiovascular anomaly that can pose significant diagnostic challenges during cardiac evaluation. We present a case of a 54-year-old male patient with chest pain and a syncopal episode and subsequently diagnosed with non-ST-elevated myocardial infarction (NSTEMI). Coronary angiography revealed an anomalous origin of the RCA, making it difficult to precisely locate the artery's point of origin with selective contrast injection. During coronary angiography, the use of aortic root non-selective angiographic contrast injection aided in localizing the RCA ostium. Our case highlights the clinical significance of aortic contrast injection as a valuable and safe adjunctive technique in cases of anomalous coronary artery origins. Early detection and precise localization of such anomalies are essential for effective treatment planning and improved patient outcomes. Further studies may help validate the utility of aortic contrast injection in similar cases, thereby enhancing diagnostic accuracy and patient care in the management of anomalous coronary artery ostium.

A Case of Myopericarditis and Cardiac Tamponade as the Initial Presentation of COVID-19 Infection.

Coronavirus disease 2019 (COVID-19) is a novel disease with various complications involving different organ systems caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. While the respiratory complications associated with COVID-19 have been well publicized, our understanding of the nonpulmonary complications of COVID-19 is lacking. Herein we present a case of a middle-aged woman who developed myopericarditis, pericardial effusion, and tamponade in the setting of COVID-19 infection.

Giant Left Main Coronary Artery Aneurysm Presenting as Multiple Implantable Cardioverter Defibrillator Shocks.

Giant aneurysms of the left main coronary artery are one of the rarest findings in cardiology, encountered in less than 0.02% of patients. The presentation is usually the same as coronary artery disease since most coronary aneurysms in the western world are associated with atherosclerosis. Here we report the first case of giant aneurysm of the left main coronary artery presenting as ventricular tachycardia with multiple shocks of the defibrillator in a 57-year-old man with heart failure. We also review the etiology, pathology, and management of coronary aneurysms.
