Spontaneous coronary artery dissection (SCAD): A contemporary review.

Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of myocardial infarction that most frequently affects younger women, making it an important cause of morbidity and mortality within these demographics. The evolution of intracoronary imaging, improved diagnosis with coronary angiography, and ongoing research efforts and attention via social media, has led to increasing recognition of this previously underdiagnosed condition. In this review, we provide a summary of the current body of knowledge, as well as focused updates on the pathogenesis of SCAD, insights on genetic susceptibility, contemporary diagnostic tools, and immediate, short- and long-term management.

What Is New in Spontaneous Coronary Artery Dissection?

Spontaneous coronary artery dissection (SCAD) is a condition that leads to tearing of the coronary vessel wall in the absence of trauma, iatrogenic injury, or atherosclerosis. SCAD is an important cause of myocardial infarction in young women, leading to significant cardiovascular morbidity and mortality. Within cohorts of women aged around 50 years on average, who experience acute coronary syndrome, the prevalence of SCAD is 22.

Pericardial effusion and systemic capillary leak syndrome late post-SARS-CoV-2 vaccination.

We report an interesting case of pericardial effusion associated with idiopathic systemic capillary leak syndrome (ISCLS) following administration of SARS-CoV-2 vaccine. This patient initially presented with dyspnoea and chest pain, with non-pitting oedema and clear lung fields. The diagnosis of ISCLS was made based on the clinical syndrome and laboratory evidence of polycythaemia and hypoalbuminaemia.

Valve-in-Valve Transcatheter Mitral Valve Replacement: A Large First-in-Human 13-Year Experience.

Background: Favourable early outcomes have been reported following valve-in-valve transcatheter mitral valve replacement (TMVR). However, reports of long-term outcomes are lacking. We aimed to evaluate early and late outcomes in a large first-in-human valve-in-valve TMVR 13-year experience.

Atherosclerotic Spontaneous Coronary Artery Dissection.

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. ().

Spontaneous Coronary Artery Dissection: Latest Developments and New Frontiers.

Purpose Of Review: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized entity leading to myocardial infarction especially in women. Multiple observational studies have been published in the recent years. This review summarizes the current body of knowledge and recent developments in SCAD epidemiology, presentation, diagnosis, and management.

Pooled Nucleic Acid Amplification Test for Screening of Stool Specimens for Shiga Toxin-Producing Escherichia coli.

Shiga toxin-producing Escherichia coli (STEC)-associated enteric illness is attributed to O157 and non-O157 serotypes; however, traditional culture-based methods underdetect non-O157 STEC. Labor and cost of consumables are major barriers to implementation of the CDC recommendation to test all stools for both O157 and non-O157 serotypes. We evaluated the feasibility of a pooled nucleic acid amplification test (NAAT) as an approach for screening stool specimens for STEC.

A comparison of revision using distal inflow and distal revascularization-interval ligation for the management of severe access-related hand ischemia.

Objective: Access-related hand ischemia (ARHI) is a potentially limb-threatening complication of arteriovenous access for dialysis. The distal revascularization-interval ligation (DRIL) and revision using distal inflow (RUDI) procedures both allow treatment of ischemic symptoms while maintaining fistula patency. Although outcomes with the DRIL are well established, experience with the RUDI for ARHI remains preliminary.
