Incomplete right bundle branch block associated with coagulation disturbance in mitral valvular disease in a dog – case report

An incomplete right bundle branch block (RBBB) associated with coagulation disturbance in mitral valvular disease was diagnosed in a five-year-old female Dachshund. Morphologically moderate mitral valvular thickening and nodularity could be noticed on echocardiography. Prolonged activated partial thromboplastin time and thrombocytopaenia supported the probable underlying mechanism for myocardial infarction and RBBB. The animal showed clinical improvement after one month of therapy with enalapril and torasemide for mitral valve insufficiency.
