Prosthetic valve thrombosis (PVT) is a life-threatening complication in pregnant women with mechanical prosthetic heart valves. Thrombolytic therapy (TT) has evolved as an effective treatment alternative to surgery, which is associated with very high maternal and fetal mortality and morbidity in these patients. Acute ischemic stroke may rarely occur during TT for PVT. Here, we present a pregnan...

BACKGROUND The factor V Leiden (FVL) mutation has been shown to be the most frequent cause of hereditary thrombophilia. The prevalence of the mutation in patients with Budd-Chiari syndrome (BCS) and portal vein thrombosis (PVT) has not been fully elucidated. AIMS To investigate the association between the FVL mutation and BCS and PVT. PATIENTS Thirty patients with BCS, 32 patients with PVT,...

Rapid rhythms often arise in the pulmonary veins during atrial fibrillation (AF). The activation patterns within pulmonary veins during these rapid rhythms are not well described. In 39 patients with paroxysmal AF, ostial recordings were obtained during AF in 110 pulmonary veins with a decapolar distal ring catheter. Pulmonary vein tachycardia (PVT) was defined as a pulmonary vein (PV) rhythm t...

Photovoltaic-thermal (PVT) technology refers to the integration of a photovoltaic (PV) and a conventional solar thermal collector, representing the deep exploitation and utilization of solar energy. In this paper, we evaluate the performance of a solar PVT cogeneration system based on specific building energy demand using theoretical modeling and experimental study. Through calculation and simu...

In recent years, with the development of photovoltaic system and photo-thermal system technology, hybrid photovoltaic-thermal (PVT) technology has been a breakthrough in many aspects. This paper describes the movable hybrid PVT system from the aspects of appearance structure, energy flow, and control circuit. The system is equipped with rolling wheels and the simulated light sources also can be...

The 10 min psychomotor vigilance task (PVT) is commonly used in laboratory studies to assess the impact of sleep loss, sustained wakefulness, and/or time of day on neurobehavioral performance. In field settings, though, it may be impractical for participants to perform a test of this length. The aim of this study was to identify a performance measure that is sensitive to the effects of fatigue ...

BACKGROUND Portal vein thrombosis (PVT) has been mentioned as a potential obstacle to liver transplantation (LTx). OBJECTIVE To review the impact of PVT on orthotopic liver transplant (OLT) outcome. METHOD Between January 2006 and April 2009, 440 OLT were performed in Shiraz Transplant Unit of whom, 35 (7.9%) cases had old PVT with recanalization. Data were retrospectively collected regardi...

INTRODUCTION Portal vein thrombosis (PVT) is a relatively uncommon complication after abdominal surgery. CASE REPORT We report an even more unusual case of PVT 10 days after an uncomplicated laparoscopic cholecystectomy, believed to be only the fourth reported case in the literature of this rare complication. CONCLUSION Albeit extremely rare, PVT should be included in the differential diagn...

Background Portal vein thrombosis (PVT) is one of the most common causes of extrahepatic portal hypertension in children, which may follow neonatal umbilical vein catheterization. The incidence rates of catheter-related PVT, in infants and children vary in different studies. This study aimed to determine PVT incidence in the children under 3 years old with a history of neonatal umbilical vein c...

BACKGROUND/AIMS Prognostic scores currently used in cirrhotic patients do not include thrombotic risk factors (TRFs). Predicting factors of portal vein thrombosis (PVT) development are still unknown. We wanted to describe TRFs as a function of liver disease severity using the MELD score and assess the role of local and systemic TRFs as predictors of PVT development in cirrhotic patients. METH...
