Congenital aneurysmal dilatation of the left atrium is a rare anomaly that could be associated with supraventricular arrhythmias and life-threatening systemic embolization. We describe a 32-year-old man with a giant left atrial aneurysm diagnosed with new imaging modalities that underwent surgical resection with good results. < Left atrial aneurysms are rare and characterized by their origin from an otherwise normal atrium, a clearly defined communication with the atrial cavity, and their intrapericardial location.

An asymptomatic 43-year-old woman visited our hospital for differential diagnosis of cardiac murmur. The transthoracic echocardiogram exhibited a dilated duct, which had turbulently accelerated color Doppler flow behind left ventricle. The coronary angiography (CAG) revealed a marked dilated left circumflex artery (LCX), which appeared to connect to coronary sinus (CS), indicating coronary artery fistula. Read More

Background: Cognitive dysfunction is the most common form of neurological impairment after aneurysmal subarachnoid hemorrhage (aSAH) in the chronic phase. Cognitive deficits in the acute phase after aSAH, however, remain scarcely investigated.

Aneurysmal subarachnoid hemorrhage (aSAH) is a highly complex disease. Majority of aSAH survivors confront post-SAH complications including cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) that mainly influence the clinical outcome. Tissue damage during early brain injury may lead to release of damage associated molecular pattern molecules (DAMPs) that may initiate and sustain inflammation during the course of aSAH through activation of pattern recognition receptors.

Cerebral metabolism alterations influence cerebrospinal fluid (CSF) composition, and is sensitive to brain injury. In subarachnoid hemorrhage (SAH) patients, Fisher scale, Hunt-Hess scale and World Federation of Neurological Societies (WFNS) grading scales evaluating SAH severity are inadequate to predict long-term outcome; therefore, in an effort to determine metabolite pattern disparity and discover corresponding biomarkers, we designed an untargeted CSF metabolomic research covering a board range of metabolites of SAH patients with different severity and outcome. The present study demonstrated SAH altered cerebrospinal fluid metabolome involving carbohydrate, lipid and amino acids metabolism. Read More

Aneurysmal rupture can result in devastating neurological consequences and can be complicated by comorbid disease processes. Patients with autosomal recessive polycystic kidney disease (ARPKD) have a low rate of reported aneurysms, but this may be due to the relative high rate of end-stage illnesses early in childhood.

Background: Ultrasound-guided percutaneous angioplasty of arteriovenous fistulas (AVFs) makes it possible to avoid contrast agents and X-rays, to optimize the puncture site and to locate some stenoses on the fistulography, but is it really useful? Our objective was to report the results of our experience.
Material And Methods: Between November 2012 and November 2017, all the patients treated according to this method in our center were collected retrospectively. The surgical indications were an insufficient maturation of the AVF, an increase in the venous pressure, an inadequate outflow, difficulties in puncture, a prolonged bleeding time, a flow drop, or an aneurysmal evolution.

The aorta is a well-organized, multilayered structure comprising several cell types, namely, endothelial cells (ECs), vascular smooth muscle cells (VSMCs), and fibroblasts, as well as an extracellular matrix (ECM), which includes elastic and collagen fibers. Aortic aneurysms (AAs) are defined as progressive enlargements of the aorta that carries an incremental risk of rupture as the diameter increases over time. The destruction of the aortic wall tissue is triggered by atherosclerosis, inflammation, and oxidative stress, leading to the activation of matrix metalloproteinases (MMPs), and inflammatory cytokines and chemokines, resulting in the loss of the structural back bone of VSMCs, ECM, and ECs.
