The study was to observe hemodynamic alterations of cardiac function to design a model of canine mitral valve insufficiency (MVI) based on chordae tendinae rupture (CTR). Ten healthy beagles with normal heart function were used in this study. To measure hemodynamics, the patient monitor was...

Mitral valve repair under cardiopulmonary bypass was performed in three dogs with clinical signs associated with mitral regurgitation that were not controlled by medication. Mitral valve repair comprised circumferential annuloplasty and chordal replacement with expanded polytetrafluoroethylene. One ...

Background: One of the purposes of treatment for dogs with mitral regurgitation (MR) is lowering left atrial pressure (LAP). There has been few study of the amlodipine in dogs with MR and amlodipine's effect on LAP has not been fully evaluated in a quantitative manner because of difficulties in...

Myxomatous degenerative valvular disease (MDVD) is the most common acquired cardiac disease in small breed dogs, characterized by slow and progressive degenerative thickening of the valvular leaflets, frequent rupture of minor order chordae tendinae and secondary valvular prolapse. The loss of...

An 11 year old male neutered Toy Poodle was presented for acute congestive heart failure due to severe degenerative mitral valve disease and ruptured chordae tendinae. After a conventional evaluation with thoracic radiographs and echocardiography, a cardiologist gave the dog a grave to guarded long ...
