'''You are presented with a one-yearold, female Giant Schnauzer for its annual vaccinations. On auscultation of the chest you detect a murmur. Part of your diagnostic evaluation includes a selective right ventricular angiogram. The radiograph pictured demonstrates the lesion.'''

Tall P waves, S waves greater than 0.35 mV in lead II and greater than 0.05 mV in lead I, presence of S waves in leads I, II, III and aVF, and deep Q waves (>0.5 mV) in leads I, II, III and aVF are consistent with right-sided cardiac enlargement.

Many dogs are asymptomatic and those with clinical signs generally have pressure gradients which warrant surgery. If left untreated, signs of right-sided heart failure develop and may be managed medically.
