OBJECTIVE To establish the incidence of systolic and diastolic dysfunction of the right and left ventricle in a large cohort of patients after Mustard or Senning operations and to assess changes in the incidence on long term follow up. DESIGN Postoperative case-control study using radionuclide ventriculography. Ejection fractions, peak filling rates, rapid filling periods and fractions, slow ...

one hundred and sixty one-day-old male broilers (ross 308) in a 6-wk period were conducted to 2 groups (with 4 replicates for each group), 20 chicks for a replicate. one group of these chickens was raised in normal temperature (nt) treatment and the other in cold temperature (ct) treatment to induce ascites. at the end of the experiment (wk 6), 2 chickens from each replicate were randomly selec...

Fi uax 1. Apical four-chamber views from preoperative two-dimensional echocardiogram showing dropout of interventriculan/septal echoes (left panel). Peripheral venous D5W injection (middle panel) at first opacifles only right atrium and ventricle, with no right-to-left shunt and possible left-to-right shunt as indicated by negative contrast effect in the right ventricle. With a premature beat, ...

introduction: nicotinamide adenine dinucleotide phosphate (nadph) oxidase-2 (nox2) is one of the predominant sources of ros production during myocardial ischemia-reperfusion and can be induced by angiotensin ii. the evidence suggests that pharmacological blockers of renin-angiotensin system can exert direct tissue effects independent of their ability to regulate blood pressure. the mechanism(s)...

Double-chambered right ventricle (DCRV) is an uncommon congenital heart disease. Anomalous muscle bundles in the right ventricle divide the right ventricle into two portions and cause intracavitary obstruction of the right ventricle. We report a patient with DCRV mimicking asymmetric septal hypertrophy. We did clinical, echocardiographic and angiographic evaluation. Surgical intervention was su...
