Background. Spontaneous coronary artery dissection (SCAD) is an underdiagnosed and rare cause of myocardial infarction (MI). SCAD is defined as the separation of the coronary artery wall by hemorrhage with or without intimal tear. It causes acute coronary syndrome in 1.7% to 4% of cases. Case Summary. We report a case of a patient with acute MI caused by SCAD with marked progression of dissection within 4 days and spontaneous healing in 2 months. Fibromuscular dysplasia (FMD) of the arteries is an associated condition of SCAD that was found in our patient. Conclusion. In young women admitted to the clinic with signs of acute myocardial infarction, SCAD should be suspected. FMD as an associated condition that should be ruled out in every SCAD patient. Conservative treatment of SCAD is the most preferable strategy.

Abstract Aims  Spontaneous coronary artery dissection (SCAD) diagnosis is challenging as angiographic findings are often subtle and differ from coronary atherosclerosis. Herein, we describe characteristics of patients with acute myocardial infarction (MI) caused by first septal perforator (S1) SCAD. Methods and results  Patients were gathered from SCAD registries at Minneapolis Heart Institute and Vancouver General Hospital. First septal perforator SCAD prevalence was 11 of 1490 (0.7%). Among 11 patients, age range was 38–64 years, 9 (82%) were female. Each presented with acute chest pain, troponin elevation, and non-ST-elevation MI diagnosis. Initial electrocardiogram demonstrated ischaemia in 5 (45%); septal wall motion abnormality was present in 4 (36%). Angiographic type 2 SCAD was present in 7 (64%) patients with S1 TIMI 3 flow in 7 (64%) and TIMI 0 flow in 2 (18%). Initial angiographic interpretation failed to recognize S1-SCAD in 6 (55%) patients (no culprit, n = 5, septal embolism, n = 1). First septal perforator SCAD diagnosis was established by review of initial coronary angiogram consequent to cardiovascular magnetic resonance (CMR) demonstrating focal septal late gadolinium enhancement with corresponding oedema (n = 3), occurrence of subsequent SCAD event (n = 2), or second angiogram showing healed S1-SCAD (n = 1). Patients were treated conservatively, each with ejection fraction >50%. Conclusion  First septal perforator SCAD events may be overlooked at initial angiography and mis-diagnosed as ‘no culprit’ MI. First septal perforator SCAD prevalence is likely greater than reported herein and dependent on local expertise and availability of CMR imaging. Spontaneous coronary artery dissection events may occur in intra-myocardial coronary arteries, approaching the resolution limits of invasive coronary angiography.

Abstract Background Spontaneous coronary artery dissection (SCAD) may be atherosclerotic (A-SCAD) or non-atherosclerotic (NA-SCAD) in origin. Contemporary usage of the term ‘SCAD’ is typically synonymous with NA-SCAD. COVID-19 could induce a vascular inflammation localized in the coronary adventitia and periadventitial fat and contribute to the development of an A-SCAD of a vulnerable plaque in a susceptible patient. Case summary In this report we describe a case of a COVID-19 patient with past cardiac history of CAD who was admitted for acute coronary syndrome (ACS). Coronary angiography demonstrated the culprit lesion in the proximal LAD that presented with a very complex and unusual morphology, indicative of an A-SCAD. The diagnosis of A-SCAD was supported by the presence of a mild stenosis in the same coronary segment in the last angiogram performed 3 years previously. He was successfully treated by PCI, had a favourable course of the COVID-19 with no symptoms of pneumonia, and was discharged from the hospital after two negative tests for SARS-CoV-2. Discussion A higher index of suspicion of A-SCAD is needed in patients with suspected or confirmed COVID-19 presenting with ACS. The proposed approach with ‘thrombolysis first’ for treating STEMI patients with suspected or confirmed COVID-19 infection could be unsafe in the case of underlying A-SCAD.

Introduction. Spontaneous coronary artery dissection (SCAD) is a rare cause of the acute coronary syndrome. It occurs mostly in patients without atherosclerotic coronary artery disease, carrying fairly high early mortality rate. The treatment of choice (interventional, surgical, or medical) for this serious condition is not well-defined. Case report. A 41-year old woman was admitted to our hospital after the initial, unsuccessful thrombolytic treatment for anterior myocardial infarction administered in a local hospital without cardiac catheterization laboratory. Immediate coronary angiography showed spontaneous coronary dissection of the left main and left anterior descending coronary artery. Follow-up coronary angiography performed 5 days after, showed extension of the dissection into the circumflex artery. Because of preserved coronary blood flow (thrombolysis in myocardial infarction - TIMI II-III), and the absence of angina and heart failure symptoms, the patient was treated medicaly with dual antiplatelet therapy, a low molecular weight heparin, a beta-blocker, an angiotensinconverting enzyme (ACE) inhibitor and a statin. The patient was discharged after 12 days. On follow-up visits after 6 months and 2 years, the patient was asymptomatic, and coronary angiography showed the persistence of dissection with preserved coronary blood flow. Conclusion. Immediate coronary angiography is necessary to assess the coronary anatomy and extent of SCAD. In patients free of angina or heart failure symptoms, with preserved coronary artery blood flow, medical therapy is a viable option. Further evidence is needed to clarify optimal treatment strategy for this rare cause of acute coronary syndrome.

Spontaneous coronary artery dissection (SCAD) is increasingly recognized as an important cause of acute coronary syndrome (ACS) and myocardial infarction (MI) in individuals with few or no known atherosclerotic risk factors. While systemic autoimmune inflammatory disorders are associated with precipitating SCAD, the role of infection-induced systemic inflammation in SCAD is not well defined. We present the case of a 49-year-old Caucasian woman with ST-elevation myocardial infarction (STEMI) diagnosed as SCAD from a severe systemic inflammatory response related to disseminated blastomycosis. Punch biopsy of a skin lesion and synovial fluid culture confirmed Blastomyces dermatitidis. This case suggests the possibility of systemic infection-induced inflammation as a precipitating factor in SCAD pathogenesis similar to autoimmune inflammatory disorders.
