Double-outlet right atrium (DORA) is a type of atrioventricular septal defect that is described as an extreme leftward deviation of the lower portion of the interatrial septum, resulting in insertion into the atrial wall left and posterior to the mitral orifice. This rare anomaly, which Hollister Outlet Sale has been reported in humans and only just recently in cats, was identified by transthoracic echocardiography in a 9 year-old cat that was presented for further evaluation of a tachyarrhythmia and cardiomegaly. This case report describes the diagnostic findings in this cat and Hollister Locations
summarizes the anatomy, classification and clinical consequences of this rare congenital heart defect.
The principal resonance of a Duffing oscillator to combined deterministic and narrow-band random parametric excitations is investigated. In particular, the case in which the parametric terms share close frequencies is examined. The method of multiple scales is used to determine the equations of modulation of amplitude and phase. The behavior, stability and bifurcation of steady state response are studied by means of qualitative analyses. Jumps are shown to occur if the random excitation is small. The effects of damping, detuning, and magnitudes of deterministic and narrow-band parametric excitations are analyzed. The theoretical analyses are verified by numerical results.
