BACKGROUND Acute ST-elevation myocardial infarction (STEMI) is caused by sudden occlusive coronary thrombosis, after plaque disruption; however, a considerable time interval between plaque disturbance and the onset of symptoms has been suggested. We therefore studied the age of intracoronary thrombi, aspirated during angioplasty in patients with acute STEMI. METHODS AND RESULTS Percutaneous i...

right-sided heart thrombus is a life-threatening condition that necessitates immediate therapy. detection of right-sided heart thrombus is usually via transthoracic echocardiography. generally, thrombolysis is considered a treatment of choice, but there is currently no consensus about the optimal therapeutic choice. we present a case of multiple right atrial thrombi with concurrent mobile and b...

OBJECTIVES This study sought to compare contrast-enhanced anatomic imaging and contrast-enhanced tissue characterization (delayed-enhancement cardiac magnetic resonance [DE-CMR]) for left ventricular (LV) thrombus detection. BACKGROUND Contrast echocardiography (echo) detects LV thrombus based on anatomic appearance, whereas DE-CMR imaging detects thrombus based on tissue characteristics. Alt...

This paper reports a case of 38-year-old young man with lower extremity arterial thrombus diagnosed by ultrasound, which was traced back to the left ventricular thrombus. By reviewing relevant literature, relationship between thrombosis and is described, examination method most valuable in diagnosis discussed.

BACKGROUND AND PURPOSE We investigated the relationship between the degree of thrombus resolution and the time from stroke onset or thrombus formation to intravenous tissue-type plasminogen activator (tPA) treatment. METHODS In patients with stroke, we measured thrombus volume on thin-section noncontrast brain computed tomographic scans taken at baseline and 1 hour after tPA administration. W...

To evaluate the clinical and histopathological effects of presurgical treatment with sunitinib on inferior vena cava (IVC) tumor thrombus. Between 2010 and 2014, we treated seven patients with renal cell carcinoma and IVC tumor thrombus presurgically with sunitinib. We retrospectively evaluated primitive tumor size, the level of tumor thrombus according to Novick's classification, its distance ...

Circulating tissue factor accumulates in the developing thrombus and contributes to fibrin clot formation. To determine whether tissue factor derived from hematopoietic cells is delivered to the thrombus via tissue factor-bearing microparticles or circulating leukocytes expressing tissue factor on the plasma membrane, we compared the kinetics of tissue factor accumulation in the developing arte...

The prediction of successful recanalization following thrombolytic or endovascular treatment may be helpful to determine the strategy of recanalization treatment in acute stroke. Thrombus can be detected using noncontrast computed tomography (CT) as a hyperdense artery sign or blooming artifact on a T2*-weighted gradient-recalled image. The detection of thrombus using CT depends on slice thickn...

BACKGROUND The presence of residual mural thrombus may predispose to recurrent thrombotic events in acute coronary syndromes. The purpose of this study was to evaluate the effects of antithrombotic and antiplatelet agents on a preformed, fresh mural thrombus during growth of thrombus. METHODS AND RESULTS A fresh mural thrombus was formed by perfusing severely injured arterial wall with porcin...

BACKGROUND Transesophageal echocardiography (TEE) is often performed during cardiac operations. The need to repeat TEE to exclude left atrial or left atrial appendage thrombus before direct current cardioversion (DCCV) in patients with a recent intraoperative TEE showing no thrombus is unclear. We sought to determine the incidence of and risk factors for new thrombus in patients undergoing TEE-...
