[Perioperative management of two patients with severe dilated cardiomyopathy].

We report perioperative management of two patients with severe dilated cardiomyopathy belonging to the group IV of classification of Inoh (ejection fraction 18% and 30%). In the preoperative period, they developed severe congestive heart failure. Dopamine, dobutamine, and furosemide were given to improve cardiac function. Anesthesia was performed safely under continuous cardiac output and mixed venous saturation monitoring. We consider that preoperative evaluation and management are very important to prevent intraoperative and postoperative complications in patients with severe dilated cardiomyopathy.
