Difficult cases in heart failure: Role of continuous ambulatory peritoneal dialysis in refractory heart failure.

Continuous ambulatory peritoneal dialysis (CAPD) offers a new modality for use in the treatment of refractory congestive heart failure (CHF). Although the use of peritoneal dialysis to treat refractory heart failure is not new, improved understanding of the physiology and technique of this system has allowed its use over prolonged periods of time. The application of continuous peritoneal dialysis to the cardiac patient changes its scope considerably.
