The reduction of the systolic function in the left ventricle of dogs with congestive heart failure is related to increased ventricular volume. Despite of the advances in conservative treatments to dilated cardiomiopathy, the prognosis is guarded with a high mortality rate. This research aimed to evaluate a surgical protocol of cardiac chamber reduction (partial ventriculectomy) to treat dilated cardiomiopathy in dogs, like the procedure realized in humans. The surgery was realized by mean inflow occlusion without cardiopulmonary by-pass. The dogs postoperative evolution of was evaluated in a short period by electrocardiogram, and simple thoracic radiography. Patients were observed for sixty days and during this period did´nt present hemodynamic alterations.
