bullet10-year-old FS Dalmatian weighing 32 kg ("Manny")

Presenting Complaints

bulletCongestive Heart Failure

Pertinent History

bullet"Manny" presented with exercise intolerance, weakness and a moist cough.
bulletHer referring veterinarian, based on a recent physical exam and chest and abdominal radiographs, diagnosed congestive heart failure.
bulletShe reportedly has had a heart murmur since the owner obtained her at four years of age.
bulletApproximately 2.5months ago she was treated by the referring DVM for coughing with 2 weeks of prednisone 20mg BID. The coughing returned post therapy and she was then treated with 2 weeks of prednisone, 20mg BID and Lasix 25mg BID. The cough returned again upon completion of the prednisone therapy.
bulletShe remains on Lasix.
bulletReferral radiographs show pulmonary edema, an enlarged cardiac silhouette, and hepatomegaly.
bulletShe is referred to the VMTH for further cardiac evaluation.
