BACKGROUND Although Doppler color flow mapping is widely used to assess the severity of mitral regurgitation (MR), a simple, accurate, and quantitative marker of MR by color flow mapping remains elusive. We hypothesized that vena contracta width by color flow mapping would accurately predict the severity of MR. METHODS AND RESULTS We studied 80 patients… (More)
BACKGROUND KIF1B gene represents the first non-inflammatory gene with a putative role on axonal loss and neurodegeneration found to be associated with multiple sclerosis (MS). The objective of this study is to test the association of the rs10492972 C allelic variant of KIF1B gene in a large Italian cohort of patients with primary progressive and progressive… (More)
3 cases of acute subdural hematoma associated with bleeding from cortical arteries are described. There was no history of trauma. Referred cases in the literature and the possible mechanisms are discussed.
BACKGROUND Patent ductus arteriosus (PDA) is one of the most common congenital heart defects in dogs. Advanced echocardiographic techniques such as speckle-tracking echocardiography (STE) have not been extensively used to evaluate cardiac function in affected dogs. HYPOTHESIS Advanced echocardiographic techniques are more sensitive than standard… (More)
BACKGROUND Subaortic stenosis (SAS) is a common congenital heart disease in Boxers. Doppler-derived aortic peak velocity (AoPV) is a diagnostic criterion for the disease. OBJECTIVES To investigate the influence of emotional stress during echocardiographic examination on AoPV in normal and SAS-affected Boxers. To evaluate the effects of aortic root… (More)
BACKGROUND Patent ductus arteriosus (PDA) is 1 of the most common congenital heart defects in dogs and percutaneous closure is effective in achieving ductal closure; PDA closure is associated with abrupt hemodynamic changes. HYPOTHESIS A marked decrease in standard parameters of systolic function as assessed by M- or B-mode echocardiography after PDA… (More)
BACKGROUND Veterinary literature lacks data about cardiovascular-renal disorders (CvRD) and cardiorenal-anemia syndrome (CRAS) in dogs. HYPOTHESIS A direct correlation exists between ACVIM class and IRIS stage; chronic kidney disease (CKD) complicates chronic mitral valve disease (CMVD) more often than does anemia in dogs. ANIMALS One hundred and… (More)
