Background: Radiography is widely used for diagnosis of congestive heart failure as it enables non-invasive assessment of cardiac size, shape and pulmonary vasculature. So, the present study was conducted to record the radiographic changes in dogs with congestive heart failure.Methods: Fifty-one dogs with cardiac insufficiency brought to Teaching Veterinary Hospital of GADVASU, showing one of the clinical signs of chronic cough, dyspnea, exercise intolerance, abdominal distension, syncope and cyanosis were selected and were subjected to Lateral and Ventro-dorsal chest radiography. Result: Dilated cardiomyopathy was present in 24 dogs. Radiographically, pulmonary edema, cardiomegaly, vessel congestion were more common in dilated cardiomyopathy (DCM). Valvular diseases were present in 16 dogs and radiographically left atrial (LA) dilatation was present in dogs with valvular diseases. Pericardial effusions were present in 11 dogs showing enlarged globoid heart radiographically.

Abstract: We report a case of a dog, male, eleven year old, american cocker spaniel with a history of acute dyspnea and exercise intolerance. The electrocardiography examination revealed the presence of ventricular arrhytmias, and, through echocardiographic examination, the patient was diagnosed with dilated cardiomyopathy and congestive heart failure. Treatment was performed, with improvement in congestive signs and arrhytmias. Ventricular arrhytmias are difficult to control in patients treated only for underlying heart disease, without the administration of antiarrythmics. The patient survived for fifteen months, emphasizing the need for early diagnosis and treatment, in order to obtain an improvement in life expectancy of patients with heart disease.

History Of

This is the first description of a left ventricular inflow tract obstruction secondary to a myxoma in a dog. A 4 yr old, male fox terrier presented with a 1 mo history of cough and exercise intolerance. Expiratory dyspnea, pulmonary crackles, irregular cardiac rhythm, and a grade 4/6 pansystolic cardiac murmur over the left cardiac apex were the most important features on physical examination. The electrocardiogram revealed atrial fibrillation. Thoracic radiographs showed left-sided cardiac enlargement and mild pulmonary edema, especially in the hilar area. Two-dimensional transthoracic echocardiography showed severe left atrial dilation and a homogenous, echodense mass involving both leaflets of the mitral valve and the posteromedial papillary muscle, inducing mitral stenosis. Spectral Doppler echocardiography was consistent with severe left ventricular inflow tract obstruction secondary to a mass. Therapy for congestive heart failure was prescribed. Follow-up examinations of the dog 1 mo, 2 mo, and 6 mo after diagnosis showed an improvement in clinical signs, but similar echocardiographic features. Eleven months after diagnosis, the dog was euthanized at the owner's request because of recurrent congestive heart failure. The postmortem examination showed the cardiac tumor was consistent with a myxoma.
