A 12-years-old mini pomeranian with clinical symptom of coughing was referred to Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Bogor Agricultural University for evaluation. The radiogram showed difus interstitial nodular pattern on the lungs and enlargement of the spleen. Abdominal ultrasonography and echocardiography was performed to further diagnose the dog. Abdominal ultrasonography was taken using linear probe with frequency 5-11 MHz. Echocardiography was perfomed with right parasternal and left apical views using microconvex probe, with frequency 6-8.8 MHz. Abdominal utrasonogram showed that the dog had billiary sludge, mild splenitis, nephrolithiasis, and urolithiasis. Two dimensional Brightness-mode echocardiography showed thickened and prolapsed mitral valve. Two-dimensional M-mode echocardiography showed increasing of left ventricle lumen dimension (LVID) at systole, decreasing of fractional shortening (FS), and enlargement of left atrial. Color Flow Doppler-mode revealed there was mild regurgitation at the mitral valve. These results lead diagnosis to dilated cardiomyopathy and myxomatous mitral valve disease

Abstract Background Myxomatous mitral valve disease (MMVD), the most common naturally-occurring heart disease in dogs, is associated with alterations in energy metabolism, oxidative stress and inflammation. Energy deprivation plays a causal role in the development of heart failure. This study was designed to determine if a cardiac protection blend (CPB) of nutrients containing medium-chain triglycerides as an alternative energy source, fish oil to reduce inflammation, antioxidants, and other key nutrients important to cardiac health and function could slow or prevent MMVD progression. Nineteen dogs with early stage MMVD and 17 breed-, age-, and sex-matched healthy dogs were enrolled for a 6-month blinded, placebo-controlled study. Dogs in each cardiac health group were randomly assigned to either control diet (CON) or CPB-supplemented diet. Echocardiography was performed at baseline, 3 months and 6 months. Results No changes were found in healthy dogs. While MMVD-CON dogs had an average 10% increase over baseline in left atrial diameter (LAD) and left atrial to aortic root ratio (LA/Ao) at 6 months, MMVD-CPB dogs showed 3% decreases, resulting significant diet by time interactions (P = 0.037, P = 0.005, respectively). More MMVD-CON dogs progressed from stage B1 to B2 during the study. A positive correlation was found between 6-month changes in LAD and blood pressures in MMVD-CPB dogs (systolic: P = 0.050, diastolic: P = 0.035) but not MMVD-CON dogs. Conclusions Our results demonstrated efficacy of CPB-based dietary intervention in reducing LA size and mitral regurgitation, and in slowing or preventing the progression of early MMVD in dogs.

Valve Diseases

Native mitral valve disease is the second valvular heart disease after aortic valve disease. For the last few decades, two-dimensional Doppler echocardiography was the cornerstone technique for evaluating patients with mitral valve disease. Besides aetiological information, echocardiography allows the description of valve anatomy, the assessment of disease severity, and the description of the associated lesions.This chapter will address the echocardiographic evaluation of mitral regurgitation (MR) and mitral stenosis (MS).In MR, the following findings should be assessed: 1. Aetiology. 2. Type and extent of anatomical lesions and mechanisms of regurgitation. 3. The possibility of mitral valve repair. 4. Quantification of MR severity. 5. Quantification of MR repercussions.In MS, the following findings should be assessed: 1. Aetiology. 2. Type and extent of anatomical lesions. 3. Quantification of MS severity. 4. Quantification of MS repercussions. 5. Wilkins or Cormier scores for the possibility of percutaneous mitral commissuroplasty.Management of patients with mitral valve disease is currently based on symptoms and on echocardiographic evaluation at rest. Therefore, knowing how to assess the severity of valve diseases as well as the pitfalls and the limitations of each echocardiographic method is of primary importance.
