Case Study

Myxomatous stage B1 mitral valve disease with systemic hypertension in a 11 year old MN Golden Retriever dog

An 11-year-old MN Golden Retriever dog was presented for evaluation of tachypnea and a grade II/VI murmur. Systolic blood pressure indicated hypertension (255/105). There was no evidence of abdominal neoplasia, renal disease, or Cushing’s disease on abdominal ultrasound examination.

Sonographic Differential Diagnosis

1.) Myxomatous Mitral Valve Disease – Stage B1, mild MR, normal LA size
2.) Systemic Hypertension – open for underlying cause, suspect primary
3.) Panting – open

Image Interpretation

The left ventricle measures normal in size. There is adequate, systolic function. The mitral valve is mildly thickened without visible prolapse. The tricuspid valve appears normal grossly. The left atrium is normal in size (La:Ao 1.13). The right heart is normal in size. Color and spectral Doppler identifies mild eccentric MR (peak velocity 7.16m/s) and physiologic TR (normal peak TR 2.36m/s). The pulmonary and aortic valves are normal in appearance. There is normal, laminar forward flow (LVOT/Ao 1.64m/s, RVOT/PA 1.09m/s). The main pulmonary artery is normal in appearance. No effusions or masses visualized. There is a sinus rhythm with average HR 130-140bpm.
