Project description:Spontaneous coronary artery dissection (SCAD) is one of the rare causes of acute coronary syndrome in young healthy individuals especially women without having any conventional risk factors for coronary artery disease. We describe a case of 34-year-old healthy man with diffuse multiple SCADs who presented with acute coronary syndrome and was managed conservatively with an uneventful course on long-term follow-up.

Project description:A 53-year-old woman underwent a cardiac catheterization for evaluation of acute coronary syndrome. The coronary angiogram revealed evidence of spontaneous coronary artery dissection in multiple coronary arteries including the left anterior descending artery, posterior descending artery, and posterior left ventricular artery. Further diagnostic imaging revealed associated bilateral vertebral artery and renal artery fibromuscular dysplasia (FMD). Follow-up coronary angiogram 6 weeks later revealed a "string of beads" appearance of the posterior descending artery. This case highlights the importance of extra-coronary imaging for FMD and demonstrates angiogram findings suggestive of coronary FMD.

Project description:BackgroundSpontaneous coronary artery dissection (SCAD) is a frequently underdiagnosed entity that carries a significant risk of morbidity and mortality. Spontaneous coronary artery dissection is increasingly recognized as an important cause of acute coronary syndrome (ACS) and, the majority of SCAD patients are young healthy women.Case summaryA 23-year-old female G5P4 presented to the emergency room for severe sub-sternal chest pain, associated with shortness of breath. Past medical history was significant for pre-eclampsia. Initial electrocardiogram was remarkable for ST depressions in V5-V6 with inverted T waves to V1-V2. Troponin I was elevated to 1.13 ng/mL. Two-dimensional echo showed reduced left ventricular function with an ejection fraction of 40%. Cardiac catheterization showed triple vessel dissection involving the left main trunk extending into mid-left anterior descending and dissection extending from ostium of left circumflex artery into large first obtuse marginal branch. She was started on aspirin and heparin. After 48 h she was loaded with clopidogrel. Computed tomography angiography of head, neck, abdomen, and pelvis showed findings compatible with fibromuscular dysplasia. She was haemodynamically stable and symptom free and did not want surgery. She was recommended to continue dual antiplatelet therapy for 12 months and subsequently aspirin and beta blocker only lifelong.DiscussionSpontaneous coronary artery dissection is a rare condition which is underdiagnosed. A thorough history and high degree of suspicion is required to diagnose in a timely manner and it should be high on differential in a postpartum female presenting with signs and symptoms of ACS.

Project description:Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction (ACS). We report a case of acute coronary syndrome due to SCAD of the right coronary artery. Diagnosis was based on clinical presentation and coronary angiography, and confirmed by optical coherence tomography which guided our treatment strategy. (Level of Difficulty: Beginner.).

Project description:Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome. Clinical presentation ranges from chest pain alone to ST-segment-elevation myocardial infarction, ventricular fibrillation, and sudden death. The treatment of patients with spontaneous coronary artery dissection is challenging because the disease pathophysiology is unclear, optimal treatment is unknown, and short- and long-term prognostic data are minimal. We report the case of a 70-year-old woman who presented with an acute ST-segment-elevation myocardial infarction secondary to a spontaneous dissection of the left anterior descending coronary artery. She was treated conservatively. Cardiac tamponade developed 16 hours after presentation. Repeat coronary angiography revealed extension of the dissection. Medical therapy was continued after the hemopericardium was aspirated. The patient remained asymptomatic 3 years after hospital discharge. To our knowledge, this is the first reported case of spontaneous coronary artery dissection in association with cardiac tamponade that was treated conservatively and had a successful outcome.

Project description:Spontaneous coronary artery dissection (SCAD) is a relatively infrequent cause of acute coronary syndrome that usually affects young to middle-aged women. Mainly because of its low prevalence, until recently, most of the evidence on this condition was derived from case reports and small series. Over the last 5 years, more robust evidence has become available from larger retrospective and prospective cohorts of patients with SCAD. The increase in knowledge and recognition of this entity has led to the publication of expert consensus on both sides of the Atlantic. However, new data are continuously accumulating from larger cohorts of patients with SCAD, bringing new light to this little-understood condition. The aim of this article is to update the knowledge on SCAD, including new information from recent studies published since the consensus documents from the European Society of Cardiology and the American Heart Association.

Project description:ImportanceSpontaneous coronary artery dissection (SCAD) is an increasingly recognized nonatherosclerotic cause of acute myocardial infarction enriched among individuals with early-onset myocardial infarction but is of unclear etiology.ObjectiveTo assess which genes contribute to the development of SCAD.Design, setting, and participantsTo prioritize genes influencing risk for SCAD, whole-exome sequencing was performed among individuals with SCAD in the discovery and replication cohorts from a tertiary care hospital outpatient specialty clinic, and gene set enrichment analyses were also performed for disruptive coding variants. All patients were sequentially enrolled beginning July 2013. Aggregate prevalence of rare disruptive variants for prioritized gene sets was compared between individuals with SCAD with population-based controls comprising 46 468 UK Biobank participants with whole-exome sequencing. Complementary mice models were used for in vivo validation. Analysis took place between June 2020 and January 2021.Main outcomes and measuresThe frequency and identity of rare genetic variants in individuals with SCAD.ResultsOf 130 patients, 109 (83.8%) were female (26 of 32 [81.2%] in the discovery cohort and 83 of 98 [84.7%] in the replication cohort) with mean (SD) age at first SCAD event of 48.41 (8.76) years in the discovery cohort and 47.74 (10.09) years in the replication cohort. Across all patients with SCAD, rare disruptive variants were found within 10 collagen genes (COL3A1, COL5A1, COL4A1, COL6A1, COL5A2, COL12A1, COL4A5, COL1A1, COL1A2, and COL27A1) were 17-fold (P = 1.5 × 10-9) enriched among individuals with SCAD compared with a background of 2506 constrained genes expressed in coronary artery. Furthermore, compared with individuals from the UK Biobank, individuals with SCAD were 1.75-fold (P = .04) more likely to carry disruptive rare variants within fibrillar collagen genes. Complementary mice models haploinsufficient for Col3a1 or Col5a1, the 2 most common collagen gene variants identified in SCAD cases, demonstrated increased risk of arterial dissection and increased size of arterial diameters especially in female mice, with resulting changes in collagen fibril organization and diameter.Conclusions and relevanceUnbiased gene discovery in patients with SCAD with independent human and murine validation highlights the role of the extracellular matrix dysfunction in SCAD.

Project description:The management of spontaneous coronary artery dissection (SCAD) presents challenges and uncertainties. We present a case of a 54-year-old woman who developed SCAD in the three primary coronary artery territories including the distal left anterior descending artery (LAD), a diagonal branch, the first and second obtuse marginals (OMs), and the midright coronary artery (RCA). She was managed conservatively without procedural intervention, and follow-up coronary angiography demonstrated complete recovery.
