The patient was presented for a pre-surgical cardiac evaluation. The patient was suffering from a rapidly progressing degenerative mitral valve. At the time of presentation the patient was on a regimen of Furosemide (8mg/kg/SID), Pimobendan (0.25 mg/kg/BID), Benazepril (0.25 mg/kg/SID), and Spironolactone (2mg/kg/SID). Despite her treatments, she was still experiencing exercise intolerance, mildly increased resting respiratory rate, and was coughing.

Despite her treatments, she was still experiencing exercise intolerance, mildly increased resting respiratory rate, and was coughing. Thoracic radiographs showed severe cardiomegaly, an increased lung opacity due to a bronchio-interstitial pattern, elevation of the trachea with possible left mainstem compression (possible airway collapse) and mildly dilated pulmonary veins.
