The echocardiogram in this patient demonstrated normal left atrial size and structure with no evidence of “smoke” or thrombi. The cranial and caudal mitral valve leaflets presented normal linear structure, extension in systole, and union in diastole. No significant dystrophic or vegetative changes were noted. The left ventricle presented normal free wall and septal thicknesses with linear contour. The chamber was neither dilated nor restricted. The myocardium presented normal echogenicity without evidence of significant fibrotic or ischemic disease. Contractility of the ventricular walls was adequate and in normal range for this breed and patient size. The left ventricular outflow tract demonstrated normal laminar flow without evidence of hemodynamically significant insufficiency or excessive outflow velocity. Tricuspid insufficiency was noted with mild to moderate right atrial enlargement. The right ventricle presented concentric hypertrophy. The pulmonary outflow tract revealed a thickened, pulmonic valve with dysplastic changes and severe elevations in velocity at 6.1 m/sec. Pulmonic insufficiency was noted and likely secondary to the primary pulmonic stenosis. No visible pericardial or free pleural fluid was noted. No echographically detectable evidence of infiltrative disease was visible. The mediastinum was free of masses in the visible window. The diaphragm was visualized without interruption. Tricuspid insufficiency 2.1 m/sec.
