Clinical introductionA 42-year-old woman presented with anterior ST elevation myocardial infarction. Urgent coronary angiography revealed tapering then occlusion of the distal left anterior descending (LAD) coronary artery with no flow in the distal LAD (figure 1A). Balloon angioplasty with a 2.0×8 mm balloon re-established flow into the distal LAD. An angiogram of the right external iliac artery was also performed (figure 1B).Figure 1Invasive angiography of the left coronary system (A) and the right external iliac artery (B). The coronary angiogram (A) shows tapering and then occlusion (arrow) of the distal left anterior descending coronary artery.QuestionWhich of the following explains the abnormal appearance of the external iliac artery (figure 1B)?Atherosclerosis.Concertina effect.Fibromuscular dysplasia.Perforation.Multiple aneurysms.

Spontaneous Dissection

Spontaneous coronary artery dissection is a rather rare cause of myocardial infarction, chest pain, and sudden death.There are currently no known direct causes of this condition.Most of the reported dissections have occurred in the left anterior descending coronary artery.Herein, we report the case of a 58-year-old woman who presented at our institution with an acute ST-elevation myocardial infarction secondary to a spontaneous dissection of the right coronary artery. Primary PCIresolved the occlusion of the artery, and the patient was discharged from the hospital on medical therapy.University Heart Journal Vol. 12, No. 2, July 2016; 105-107

Infective endocarditis complicated by abscess formation and coronary artery compression is a rare clinical event with a high mortality rate, and diagnosis requires a heightened degree of suspicion. We present the clinical, angiographic, and echocardiographic features of a 73-year-old woman who presented with dyspnea and was found to have right coronary artery compression that was secondary to abscess formation resulting from diffuse infectious endocarditis. We discuss the patient's case and briefly review the relevant medical literature. To our knowledge, this is the first reported case of abscess formation involving a native aortic valve and the right coronary artery.

Coronary artery aneurysm (CAA) is a rare cause of myocardial infarction. However, only a few studies have investigated this aspect. An 84-year-old woman with a history of hypertension presented with nausea. showed ST elevation in the inferior leads, and coronary angiography revealed two giant CAAs in the right coronary artery. Percutaneous coronary intervention was difficult because of risk of CAA rupture. Thus, these aneurysms were further evaluated using multimodality cardiac imaging to determine the treatment. MRI using late gadolinium enhancement revealed structural features of the aneurysms and the viability of the myocardium. Only antithrombotic medication was administered on the basis of the results of the multimodality cardiac imaging. Here, we report a rare case of a patient diagnosed with ST elevation myocardial infarction caused by thrombosis in giant CAAs using multimodality cardiac imaging, particularly MRI.

Introduction. Electrocardiography is an initial non-invasive diagnostic algorithm for ST elevation acute myocardial infarction. Specific electrocardiographic phenomenon is described, when the occlusion of the proximal segment of the right coronary artery or the isolated occlusion of its ventricular branch is presented with ST elevation in the precordial leads. Case Report. A 78-year-old woman was admitted as an emergency due to chest pain and electrocardiographically recorded concave elevation in leads V1 - V3. She was diagnosed with ST elevation myocardial infarction of the anterior region and sent to catheterization laboratory for emergency coronary angiography. It showed an occlusion of the proximal-medial right coronary artery. Behind the occlusion, the right coronary artery, posterior descending artery and posterior lateral artery, a hetero-collateral circulation was seen. Two drug-eluting stents were implanted into the proximal segment of the right coronary artery. Discussion. The phenomenon of acute myocardial infarction caused by occlusion of the proximal right coronary artery and/or ventricular branches of the right coronary artery, presenting with ST segment elevation in the precordial leads, is a consequence of several anatomical variations: occlusion of nondominant right coronary artery, isolated occlusion of the ventricular branch of the right coronary artery, and the occlusion of the right coronary artery proximal to the ventricular branch with hetero collateral circulation on the periphery of the right coronary artery, like in our case. Electrocardiographic characteristic pointing to the occlusion of the proximal right coronary artery and/or ventricular branches of the right coronary artery is higher ST elevation in the lead V1 than in the other leads, followed by the absence of Q wave development. This ST elevation is concave. Conclusion. It is necessary to emphasize the significance of differential diagnosis of culprit lesion in patients with chest pain and elevation of the ST segment in the precordial leads having in mind further different thera peutic algorithms. Patients with right ventricular myo cardial infarction need to maintain an adequate ?preload? and avoid vasodilators in order to maintain the right ventricular stroke volume.

COVID-19 is a prothrombotic condition that is also associated with raised troponin levels and myocardial damage. We present a case of a 54-year-old man who was admitted with respiratory failure due to COVID-19 and developed a ST-elevation myocardial infarction (STEMI) during his admission. His coronary angiogram did not show any significant coronary artery disease other than a heavily thrombosed right coronary artery. In view of heavy thrombus burden, the right coronary artery was treated with thrombus retrieval using a distal embolic protection device in addition to manual thrombectomy and direct (intracoronary) thrombolysis without the need for implantation of a coronary stent. After successful revascularisation, triple antithrombotic therapy was instituted with an oral anticoagulant in addition to dual antiplatelets. This case illustrates the association of COVID-19 with coronary artery thrombosis, which may require disparate management of a STEMI than that resulting from atherosclerotic coronary artery disease.
