Project description:Spontaneous coronary artery dissection is a rare but potentially life-threatening condition that predominantly affects women, particularly during pregnancy or postpartum period. We present a case of peripartum spontaneous coronary artery dissection in a 41-year-old African woman, highlighting the clinical presentation, diagnostic challenges, and management strategies.

Project description:Spontaneous coronary artery dissection is a nontraumatic, noniatrogenic intimal tearing of the coronary artery in patients without atherosclerotic coronary disease. We present 3 unique cases of patients with spontaneous coronary artery dissection and atherosclerotic coronary artery disease. (Level of Difficulty: Intermediate.).

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) occurs when an epicardial coronary artery is narrowed or occluded by an intramural hematoma. SCAD mainly affects women and is associated with pregnancy and systemic arteriopathies, particularly fibromuscular dysplasia. Variants in several genes, such as those causing connective tissue disorders, have been implicated; however, the genetic architecture is poorly understood. Here, we aim to better understand the diagnostic yield of rare variant genetic testing among a cohort of SCAD survivors and to identify genes or gene sets that have a significant enrichment of rare variants.MethodsWe sequenced a cohort of 384 SCAD survivors from the United Kingdom, alongside 13 722 UK Biobank controls and a validation cohort of 92 SCAD survivors. We performed a research diagnostic screen for pathogenic variants and exome-wide and gene-set rare variant collapsing analyses.ResultsThe majority of patients within both cohorts are female, 29% of the study cohort and 14% validation cohort have a remote arteriopathy. Four cases across the 2 cohorts had a diagnosed connective tissue disorder. We identified pathogenic or likely pathogenic variants in 7 genes (PKD1, COL3A1, SMAD3, TGFB2, LOX, MYLK, and YY1AP1) in 14/384 cases in the study cohort and in 1/92 cases in the validation cohort. In our rare variant collapsing analysis, PKD1 was the highest-ranked gene, and several functionally plausible genes were enriched for rare variants, although no gene achieved study-wide statistical significance. Gene-set enrichment analysis suggested a role for additional genes involved in renal function.ConclusionsBy studying the largest sequenced cohort of SCAD survivors, we demonstrate that, based on current knowledge, only a small proportion have a pathogenic variant that could explain their disease. Our findings strengthen the overlap between SCAD and renal and connective tissue disorders, and we highlight several new genes for future validation.

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 (SCAD) is an increasingly recognized cause of acute myocardial infarction. We examine 4 atypical presentations of SCAD. These cases highlight treatment course and outcomes for patients with SCAD who do not present with acute coronary syndrome.

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:Background The long-term course of coronary atherosclerosis has not been studied in large nationwide cohorts. Understanding the natural history of coronary atherosclerosis could help identify patients at risk for future coronary events. Methods and Results All coronary artery segments with <50% luminal stenosis in patients with a first-time coronary angiogram between 1989 and 2017 were identified (n=2 661 245 coronary artery segments in 248 736 patients) and followed until a clinically indicated angiography within 15 years was performed or until death or end of follow-up (April 2018) using SCAAR (Swedish Coronary Angiography and Angioplasty Registry). The stenosis progression and incidence rates were 2.6% and 1.45 (95% CI, 1.43-1.46) per 1000 segment-years, respectively. The greatest progression rate occurred in the proximal and middle segments of the left anterior descending artery. Male sex and diabetes were associated with a 2-fold increase in risk, and nearly 70% of new stenoses occurred in patients with baseline single-vessel disease (hazard ratio, 3.86 [95% CI, 3.69-4.04]). Coronary artery segments in patients with no baseline risk factors had a progression rate of 0.6% and incidence rate of 0.36 (95% CI, 0.34-0.39), increasing to 8.1% and 4.01 (95% CI, 3.89-4.14) per 1000 segment-years, respectively, in patients with ≥4 risk factors. The prognostic impact of risk factors on stenosis progression was greatest in younger patients and women. Conclusions Coronary atherosclerosis progressed slowly but more frequently in the left coronary artery in men and in the presence of traditional risk factors. Coronary artery segments in patients without risk factors had little or no risk of stenosis progression, and the relative impact of risk factors appears to be of greater importance in younger patients and women. These findings help in the understanding the long-term course of coronary atherosclerosis.
