Arms	Assigned Interventions
1 Patients will have water immersion on first day and sitting in a tub without water on the second day.	Procedure: Water immersion Subjects will sit in tub for four hours.
2 Patients will sit in a tub without water on the first day and have water immersion on the second day.	Procedure: Water immersion Subjects will sit in tub for four hours.

Detailed Description:

Patients will be immersed in a tub for 3 hours (on one day) and neurohormones will be obtained before and after immersion. Urine will be collected for quantification and evaluation of sodium concentration.

Eligibility

Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Patients must have right sided failure secondary to right ventricular dysfunction, pulmonary hypertension, or tricuspid regurgitation
Age greater than 18 years of age
Right heart catheterization within the last year to rule out left-sided failure.
Evidence of fluid overload as indicated by 2 or more of the following: 1.) 2+ or more pitting edema of the lower extremities, 2.) scrotal or penile edema, 3.) JVP greater than or equal to 10 cm, 4.) abdominal ascites

Exclusion Criteria:

Pulmonary capillary wedge pressure above 16 mmHg or history of elevated left ventricular filling pressures.
Serum creatinine > 2.0
Current use of an angiotensin I converting enzyme inhibitor or angiotensin receptor blocker will preclude participation in the RAS neurohormone portion of the study.
