Heart failure unresponsive to bed rest, low sodium diet, digitalis, diuretics, vasodilators and cardiac inotropic agents is a difficult therapeutic problem. Although remission was achieved with such treatment, its duration was short and easily recurred. We present a report of severe refractory congestive heart failure in three patients successfully treated with Continuous Ambulatory Peritoneal Dialysis (CAPD). These patients were admitted to the hospital many times and treated by conventional methods but cannon maintain their condition for a long time.
