Case reports of coronary fibromuscular dysplasia and spontaneous coronary artery dissections

AbstractSpontaneous coronary artery dissection (SCAD) is an important cause of acute coronary syndrome especially in women. The most common underlying predisposing cause of SCAD is fibromuscular dysplasia (FMD), a non ‐inflammatory arteriopathy that results in weakening of the affected arteries, and can cause dissection or aneurysm. Coronary FMD (CFMD) was described as rare, and was shown to cause SCAD in histopathological case reports. Unfortunately, CFMD is challenging to diagnose on coronary angiography, as the findings can be similar to other causes of coronary artery disease. Therefore, we illustrate two case examples of CFMD on coronary angiography, and highlight findings on optical coherence tomography to aid diagnosis.

Conclusion The best algorithm to localise the culprit artery includes ST-elevation in leads II and V6 related to Cx, and ST-elevation in leads III, aVF and V3 related to right coronary artery. Our algorithm has been validated internally and externally, and works better than other previously published algorithms.

Background Visual–functional mismatch between coronary angiography and fractional flow reserve (FFR) has been reported, and the underlying reason remains poorly understood. Therefore, the relationship between angiographic measurements and FFR was evaluated, and predictors for FFR in intermediate coronary artery stenosis were determined. Methods Consecutive 314 patients (405 lesions) with a lesion of 30–80% angiographic diameter stenosis who underwent invasive FFR were recruited. The myocardial area supplied by the coronary artery distal to the stenosis was evaluated using a modified version of the Bypass A...

Background Cardiovascular disease is one of the leading causes of death worldwide. According to the results of various studies, protein convertase subtilisin kexin type-9 (PCSK9) was determined as a novel risk factor for stable coronary artery disease. Few studies have investigated the relationship between PCSK9 levels and the severity of coronary artery disease in patients with acute coronary syndrome; thus, we herein aimed to investigate this relationship in patients with non-ST-elevation myocardial infarction (NSTEMI) who underwent coronary angiography. Patients and methods Herein, 168 patients with NSTEMI were pro...

In this study, synchrotron radiation (SR)-based X-ray in-line phase-contrast imaging (ILPCI) and quantitative 3D characterization were used to acquire high-resolution, high-contrast images of rat brain tissue under both normal and seizure conditions. The number of blood microvessels was markedly increased on days 1 and 14, but decreased on day 60 after seizures. The surface area, diameter distribution, mean tortuosity, and number of bifurcations and network segments also showed similar trends. These pathological changes were confirmed by histological tests. Thus, SR-based ILPCI provides systematic and detailed views of cer...

ConclusionsA delay in diagnosis increases the rate of complications, mainly infectious complications and the formation of granulation tissue that could potentially obstruct the airway, impacting the patient ’s outcome. The first step in the management of these patients is securing the airway, which should be done immediately. The gold standard for the diagnosis and characterization of airway injuries is bronchoscopy as it is the most effective tool to assess topography, extent, and depth of the lesio n.
