Pulmonary Vein‐to‐Pulmonary Artery Ratio is an Echocardiographic Index of Congestive Heart Failure in Dogs with Degenerative Mitral Valve Disease
BACKGROUND Early recognition of left-sided congestive heart failure (CHF) in dogs with degenerative mitral valve disease (DMVD) is important because it influences medical therapy, timing of follow-up, and outcome. HYPOTHESIS Pulmonary vein diameter-to-pulmonary artery diameter ratio (PV/PA) measured by echocardiography can predict CHF. ANIMALS Ninety-eight client-owned dogs, 37 controls, an...
متن کاملEchocardiographic diagnosis of isolated pulmonary valve endocarditis.
A 46-year-old man, known to have an undiagnosed asymptomatic congenital heart defect, had a high temperature in November 1979. He was treated with antibiotics which were at first effective but pyrexia reappeared two weeks later. Cephalosporin was given intravenously for 10 days, but the patient became very weak, and haemorrhagic purpura appeared on the legs; evening pyrexia persisted. Finally, ...
متن کاملRight pulmonary to left pulmonary perfusion ratio after percutaneous pulmonary valve implantation
Background Percutaneous pulmonary valve implantation (PPVI) requires the positioning of a stiff guidewire into one of the pulmonary branch arteries. An infrequent but commonly known complication is the “jailing” of one of the pulmonary branch arteries. However, even without apparent “jailing” of one of the pulmonary branch arteries, we suspect that the technique of stent placements often has an...
متن کاملEchocardiographic determinants of clinical course in infants with critical and severe pulmonary valve stenosis.
OBJECTIVES The purposes of this study were to determine the growth pattern of the pulmonary valve (PV) annulus and right heart structures in patients with critical and severe pulmonary stenosis (PS) after balloon dilation, and to determine any morphometric or hemodynamic differences between cyanotic infants with critical PS and asymptomatic infants with severe PS that may account for their vari...
متن کاملLung hypoplasia in congenital pulmonary valve stenosis.
The pulmonary function of ten adult patients with congenital pulmonary valvular stenosis was investigated. The patients clearly showed smaller lungs than healthy control subjects of equivalent age and height; lung elastic recoil pressure was normal at any given percentage of measured total lung capacity, indicating that postnatal parenchymal damage is not the cause of the small lungs. The lung ...
