|
A 1-year-old castrated male Maltese dog(weighing 2.4 kg) was presented with primary complaints of occasional coughing, dyspnea and exercise intolerance. Based on diagnostic findings including paradoxical split S2, diastolic regurgitant murmur, marked dilation of pulmonary artery, right ventricular eccentric hypertrophy with thickening of ventricular septum, severe tricuspid and pulmonic regurgitation(5.4 m/sec and 3.4 m/sec, respectively) and the absence of any congenital intracardiac shunting, obstructive pulmonary diseases and systemic diseases associated with right ventricular pressure overload or pulmonary hyperperfusion, the case was tentatively diagnosed as primary pulmonary hypertension. The dog was treated with furosemide, aspirin and oxygen supplementation. This case report described a rare case of primary pulmonary hypertension in a Maltese dog.
