INTRODUCTION Prosthetic valve thrombosis (PVT) following cardiac valve replacement in rheumatic heart disease patients is a common cause for referral to tertiary care centre. Although surgery has been described as the traditional choice of therapy, thrombolytic therapy has reported high success rates in published literature. CASE REPORT This is a case report of ten patients with left-sided PV...

PVT (Pressure-Volume-Temperature) properties of polymers are important for both engineering and polymer physics. Fig.1 shows the typical PVT diagrams of an amorphous (a) and semi-crystalline polymer (b). PVT diagram describes the specific volume as a function of pressure and temperature. Specific volume increases with the temperature increasing. There is a thermal transition in the polymer. The...

In order to determine the role of the coupling interval of a premature ventricular contraction (PVC) in the development of paroxysmal ventricular tachycardia (PVT) during the early phase of acute myocardial infarction in man, 52 male patients with documented acute myocardial infarction had 24-hour Holter monitoring commenced within 24 hours of the onset of prolonged chest pain. Review of the ta...

Portal vein (PV) thrombosis (PVT) is a rare condition with development of thrombosis in the PV and its branches. Further extension to the splenic and superior mesenteric vein (SMV) causes intestinal infarction, with a reported mortality of up to 50%. A variety of treatments for PVT exist including anticoagulation, thrombolysis, surgical thrombectomy, insertion of shunts, bypass surgery, and liv...

Equations of state are useful for description of fluid properties such as pressure-volumetemperature (PVT). However, the success estimation of such correlations depends mainly on the range of data which have originated. Therefore new models are highly required. In this work a new method is proposed based on Artificial Neural Network (ANN) for estimation of PVT properties of compounds. The data ...

The hallmark manifestations of Cushing's syndrome (CS) are well known, but hypercoagulability is perhaps least recognized. Patients with CS are at increased risk of both spontaneous and postoperative thromboembolism, with the significant majority of events occurring in the lower extremity and pulmonary venous circulations. We present a case of portal vein thrombosis (PVT) occurring in the setti...

A prior report found unusually high rates of performance validity test (PVT) failure in undergraduate research participants (31%-56%). The present study examined 110 undergraduate volunteers in three conditions (positive, neutral, or negative demand characteristics) in either an easy to hard or a hard to easy progression of neuropsychological tests using the Word Memory Test PVT. Neither demand...

Performance validity tests (PVTs) have been shown to relate to neuropsychological performance, but no studies have looked at the ecological validity of these measures. Data from 131 veterans with a history of mild traumatic brain injury from a multicenter Veterans Administration consortium were examined to determine the relation between scores on a self-report version of the Mayo-Portland Adapt...
