introduction the eustachian valve (ev) remnant, when present in adults, is usually rudimentary. however, in echocardiographic examinations, it may appear as a mobile long structure in the right atrium, and it rarely protrudes into the right ventricle. when it is quite large, the ev remnant could be misdiagnosed as a right atrial tumor, thrombus, or vegetation. case presentation an 83-year-old p...

the main goal of this report was to share with clinicians an atypical presentation of pulmonary thromboembolism (pte) in a young male`s post-appendectomy, whom he had no significant predisposing factors for such disease. the case also introduced for re-examining the challenges of pte clinical manifestations which may mimic other differential diagnosis. pte is an abrupt blockage of the pulmonary...

BACKGROUND Experimental studies have demonstrated that intracoronary platelet aggregation and thrombus formation may induce marked vasoconstriction of epicardial arteries with endothelial injury. METHODS AND RESULTS To examine the effects of intracoronary thrombus formation on coronary vasomotor tone of human epicardial arteries in vivo, we studied 15 patients who developed intracoronary thro...

OBJECTIVE Association between inflammation and pro-thrombotic state has been described previously. Aim of the present study was to investigate if presence of left atrial (LA) thrombus or spontaneous echocardiographic contrast (SEC) in rheumatic mitral stenosis (MS) was related to neutrophil/lymphocyte ratio (NLR), and to determine predictive utility of the CHA2DS2-VASc risk stratification score...

OBJECTIVE To investigate the relation between intracardiac thrombus and blood coagulability in patients with mitral stenosis. DESIGN Prospective study. Cross sectional echocardiography and plasma concentrations of the D-dimer fragment of fibrin were used concurrently to detect intracardiac thrombus in patients with mitral stenosis. SETTING Department of Medicine, National Cardiovascular Cen...

Background. Experimental studies have demonstrated that intracoronary platelet aggregation and thrombus formation may induce marked vasoconstriction of epicardial arteries with endothelial injury. Methods and Results. To examine the effects of intracoronary thrombus formation on coronary vasomotor tone of human epicardial arteries in vivo, we studied 15 patients who developed intracoronary thro...

BACKGROUND In patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) with thrombus aspiration, the histopathology of aspirated thrombus was previously related to long-term mortality. In this study, we sought to investigate the association between histopathology of aspirated thrombus and ST-segment recovery, a marker of microv...

BACKGROUND AND PURPOSE In acute ischemic stroke (AIS) management, CT-based thrombus density has been associated with treatment success. However, currently used thrombus measurements are prone to inter-observer variability and oversimplify the heterogeneous thrombus composition. Our aim was first to introduce an automated method to assess the entire thrombus density and then to compare the measu...

Background—Persistent intracoronary thrombus after plaque rupture is associated with an increased risk of subsequent myocardial infarction and mortality. Coronary thrombus is usually visualized invasively by x-ray coronary angiography. Non–contrast-enhanced T1-weighted magnetic resonance (MR) imaging has been useful for direct imaging of carotid thrombus and intraplaque hemorrhage by taking adv...

Thrombus formation on collagen fibrils was quantified at venous (100/s) and arterial (650/s and 2,600/s) wall shear rates in blood from patients with various subtypes of von Willebrand disease (vWD) and with hemophilia A (HA). Nonanticoagulated blood was drawn directly from an antecubital vein over purified type III collagen fibrils exposed in parallel-plate perfusion chambers. Blood-collagen i...
