Abstract

A three-month-old male pug was presented with the complaint of syncopal episodes. Clinical examination revealed cyanotic mucosa, systolic murmur, weak pulse, with sinus tachycardia, p-pulmonale, increased R amplitude and ST elevation on electrocardiogram. On detailed cardiologic evaluation, altered cardiac silhouette, sluggish ventricular contractility, enlarged atria and ventricles, severe turbulent flow on the interventricular septum, increased CPK, hyponatremia and hypoproteinemia were found. Therapeutic management with enalapril, digoxin, diltiazem and lasilactone were attempted. The animal succumbed to death following episode of syncope at home. The post-mortem disclosed cardiomegaly and a defect in the membranous portion of the interventricular septum. Based on the post-mortem findings, the case was diagnosed as ventricular septal defect.
