Background Acute aortic syndrome is the modern term that includes aortic dissection, intramural hematoma, and symptomatic aortic ulcer. Iatrogenic coronary artery dissection extending to the aorta during percutaneous coronary intervention is a very rare but life-threatening complication. Despite some reports of spontaneous recovery, most of these patients are treated surgically ...

Coronary artery ectasia (CAE) is characterized by inappropriate dilatation of the coronary vasculature. The mechanisms of CAE are not well known. Insulin-like growth factor-1 (IGF-1) may make endothelial cells and smooth muscle cells more sensitive to the effects of growth hormone. In the present study, we hypothesized that IGF-1 may ...

Cutaneous complications can result from nontarget deposition during transcatheter arterial chemoembolization or radioembolization. Liver tumors may receive blood supply from parasitized extrahepatic arteries (EHAs) that also perfuse skin or from hepatic arteries located near the origin of the falciform artery (FA), which perfuses the anterior abdominal wall. To vasoconstrict cutaneous ...

Dirofilaria immitis adult worms lodged in the pulmonary arteries are the causative agent of heartworm disease, characterized by endarteritis and obstruction of the blood flow. Dying worms form embolic fragments which trigger thrombosis. Thus, pulmonary thromboembolism is an inevitable consequence of successful adulticide therapy. Clinical signs of pulmonary thromboembolisms are ...

As a rare procedure, massive bronchoalveolar lavage (MBAL) is a large-volume lavage which necessitates general anesthesia and one-lung ventilation (OLV). During MBAL isotonic saline is instilled into one lung and drained through one lumen of a double-lumen tube. MBAL is the most effective treatment for symptomatic pulmonary alveolar proteinosis (PAP). ...

Responses to a selective azaindole-based Rho kinase (ROCK) inhibitor (azaindole-1) were investigated in the rat. Intravenous injections of azaindole-1 (10-300 µg/kg), produced small decreases in pulmonary arterial pressure and larger decreases in systemic arterial pressure without changing cardiac output. Responses to azaindole-1 were slow in onset and long in duration. When ...

Introduction.  Rho kinases (ROKs) cause calcium-independent modulation of smooth muscle contraction. A significant role for the RhoA/ROK pathway in mediating the contraction of the penile erectile tissue has been suggested. Moreover, it has been postulated that ROK activity might represent a key factor in the pathophysiology of erectile dysfunction. Up ...

Saphenous vein grafts used in coronary artery bypass graft surgery suffer from lower patency rates compared to left internal mammary artery. A number of clinical trials and observational studies have demonstrated a significant benefit of statin treatment on vein graft patency. Aside from their well-known lipid-lowering capacities, statins exert pleiotropic ...

BACKGROUND: Endovascular technology has advanced rapidly in the development of fenestrated endovascular aneurysm repair (FEVAR). Current evidence for endovascular aneurysm repair is limited to infra-renal aortic aneurysms. With increased costs and complexity of FEVAR, its current role is unclear. A national multicentre, cross-disciplinary consensus model was developed to propose indications ...

The phylogenetic position of Euphausiacea within Malacostraca is still under debate. Either they are seen as sister group to a taxon comprising Pancarida and Peracarida or closer related to Decapoda. Both hypotheses can be supported by characters of the circulatory system. Therefore, a comparative re-evaluation of the circulatory system seems ...

For many years the lung has been considered off-limits for ultrasound. However, it has been recently shown that lung ultrasound (LUS) may represent a useful tool for the evaluation of many pulmonary conditions in cardiovascular disease. The main application of LUS for the cardiologist is the assessment of B-lines. B-lines ...

Double-arterial coronary stent thrombosis in acute myocardial infarction (AMI) is an infrequent but severe complication, especially when the third main coronary artery is chronically occluded. The conus artery (CA) can serve as a major source of collateral when the left anterior descendent coronary artery (LAD) becomes obstructed. We report a ...
