Ventricular septal defect with aortic valve insufficiency in a New Zealand White rabbit.

摘要: A heart murmur was detected in a 10 mo old, female New Zealand White rabbit. Auscultation revealed cardiac murmurs both at the left and right hemithorax. Phonocardiography confirmed systolic–diastolic nature of left-sided systolic character right-sided murmur. Electrocardiography showed normal sinus rhythm; tall R waves large T lead II; deep S leads II, III, aVF. Thoracic radiography demonstrated generalized cardiomegaly with prominent pulmonary vasculature. Echocardiography perimembraneous ventricular septal defect aortic insufficiency. Signs biventricular volume overload, relative pulmonic stenosis, valve insufficiency were also seen as consequences defect. Necropsy just below valve, dilated trunk, hypertrophied ventricles, atria, rightward displacement root. Cardiac histopathology cardiomyocy...
