Abstract

A 14-year-old intact female Cocker Spaniel dog, weighing 6.8 kg, presented with chief complaints of severe cough, dyspnea, anorexia, and exercise intolerance. It had the characteristics of a blood clot, the evidence of mitral regurgitation, a high left atrial/aortic root ratio, and pericardial effusion with a left atrial rupture due to myxomatous mitral valve degeneration (MMVD) was strongly suspected. Traditional therapy (pimobendan, furosemide, enalapril, and spironolactone) for heart failure with MMVD was provided twice a day orally, and partial pericardiectomy was performed for pericardial effusion. The medical prescriptions for MMVD were continued, and the patient’s heart disease was well-controlled. However, it suddenly died 3 months after the operation.

Keywords: atrial rupture, dog, echocardiography, myxomatous mitral valve degeneration, pericardial effusion
