May support short-term palliation in canine left atrial rupture; hypothesis-generating and requires prospective validation.
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.

Han et al. (2020) conducted a case report in Pericardial effusion caused by left atrial rupture due to myxomatous mitral valve degeneration (n=1). Partial pericardiectomy and medical management was evaluated on Clinical outcome and survival. Partial pericardiectomy combined with medical management resolved pericardial effusion and controlled heart disease, resulting in a 3-month survival in a dog with suspected left atrial rupture.
