Brief Summary

Congestive heart disease (CHF) can frequently cause transudative pleural effusions, some of which do not completely resolve with diuretics alone. These effusions can cause significant morbidity, leading to ongoing dyspnea and hypoxia, resulting in additional office and hospital visits. TREAT-CHF is a randomized trial studying tunneled pleural catheter (TPC) versus standard medical management for the treatment recurrent symptomatic pleural effusions secondary to CHF that are refractory to maximal medical therapy. TREAT-CHF will study whether the addition of a TPC can improve quality of life and minimize health care utilization over the one year following insertion.

Detailed Description

TREAT-CHF is a randomized trial studying tunneled pleural catheter (TPC) versus standard medical management for the treatment recurrent symptomatic pleural effusions secondary to CHF that are refractory to maximal medical therapy. All trial participants will be adults with congestive heart failure (CHF) already managed with maximal medical therapy, as determined by their cardiologist or primary physician. Patients will demonstrate recurrent transudative or pseudoexudative pleural effusions caused solely by CHF that have not been controlled with medical therapy alone. Included patients must also show documented subjective symptomatic relief with thoracentesis.

Patients will be randomized to the intervention group or control group. The intervention group will receive a tunneled pleural catheter (TPC) in addition to their current medical treatment. The control group will continue with medical therapy by their referring physician and serial thoracenteses when clinically appropriate. Patients will then be followed over the course of once year after enrollment. The TPC will be drained daily for symptomatic relief. Several outcomes, including quality of life based on periodic self-survey and healthcare utilization determined by chart review (emergency room visits and hospital stays), will be studied. Adverse outcomes of TPC insertion and sequelae of frequent pleural space drainage will be documented.

Inclusion Criteria

1. Age > 18 years of age at enrollment
2. Able to give consent
3. Documented heart failure defined by echocardiography demonstrating depressed left ventricular ejection fraction and/or left ventricular diastolic dysfunction
4. Recurrent and symptomatic pleural effusions refractory to medical management
5. Maximal medical management will be determined by the referring provider a. This should include use of at least three of the classes of medications that are standard of care for heart failure: i. Angiotensin converting enzyme inhibitor or angiotensin receptor blockers ii. Beta blockers iii. Loop diuretics iv. Potassium-sparing diuretics b. If the patient is not on at least three drugs from the above classes, documentation of drug intolerance must be present
6. Documented subjective symptomatic relief after thoracentesis and drainage of the pleural space
7. Pleural fluid clinically determined to be due only to CHF
8. Pleural fluid analysis consistent with transudate or pseudoexudate a. Transudate: defined by Light's criteria, all of the following must occur, i. Pleural:serum lactate dehydrogenase (LDH) < 0.6 ii. Pleural LDH < 2/3 x upper limit of normal of serum LDH iii. Pleural:serum protein < 0.5 b. Pseudoexudate: defined by all of the following, i. Pleural:serum LDH > 0.6 but < 1 ii. Pleural:serum protein < 0.5 iii. Serum-pleural protein gradient > 3.2 and/or serum-pleural albumin gradient > 1.2

Arm && Interventions

Group	Intervention	Description
Intervention Group	tunneled pleural catheter	This group will receive placement of a tunneled pleural catheter to drain their recurrent, chronic, and symptomatic pleural effusion in addition to their usual medication therapy.

Primary Outcome Measures

Name	Time	Method
Change in quality of life scores from baseline as measured by the Minnesota Living with Heart Failure Questionnaire	Change from baseline at 3 time points over the year of follow up (3, 6, and 12 months)	Quality of life will be measured by the Minnesota Living with Heart Failure Questionnaire at four time points
Incidence of hospitalizations and emergency room encounters	1 year post-enrollment	Measurement of all significant health care visits, including hospitalizations and emergency room encounters

Secondary Outcome Measures

Name	Time	Method
Incidence of pleural procedures	1 year post-enrollment	By convention, the intervention group will have one pleural procedure (TPC placement). Any additional thoracenteses, video-assisted thoracoscopic surgery, or chest tubes on either side of the chest will be documented for both groups. Removal of or manipulation of TPC will not be recorded as an additional pleural procedure.
Incidence of pleural space or chest wall infection	1 year post-enrollment	Pleural space infection is defined as a positive pleural fluid culture. Chest wall infection will be defined clinically, based on the presence of cellulitis surrounding the catheter or catheter tract, or pus draining from the catheter insertion site.
Change from baseline serum creatinine	Change from baseline at 3 time points over the year of follow up (3, 6, and 12 months)	serum creatinine levels
Incidence of hemothorax	1 year post-enrollment	Hemothorax is defined as a pleural hematocrit or red blood cell count (RBC) exceeding 50% that of the serum hematocrit or RBC count.
Incidence of trapped lung, loculated pleural effusion, and pneumothorax	1 year post-enrollment	Trapped lung is defined as a lung that does not expand after pleural fluid drainage leaving a pneumothorax ex-vacuo or hydropneumothorax. Pneumothorax and loculated pleural effusion will be determined based on classic imaging characteristics.
Time to pleurodesis among those who achieved pleurodesis	1 year post-enrollment	The number of days from enrollment (control group) or TPC placement (intervention group) to pleurodesis among those who achieved pleurodesis will be recorded. Pleurodesis is defined as apposition of the parietal and visceral pleural such: (i) that the subject drains less than 10cc on three serial drainages, (ii) there is resolution of the pleural effusion on both chest x-ray (CXR) and chest ultrasound, (iii) the TPC is removed, and (iv) the pleural effusion does not accumulate after TPC removal as evidence by CXR and chest ultrasound.
Change from baseline serum albumin	Change from baseline at 3 time points over the year of follow up (3, 6, and 12 months)	serum albumin levels
Rate of hemodialysis initiation	1 year post-enrollment	We will record patients who develop worsening renal failure, necessitating initiation of hemodialysis
All cause mortality	1 year post-enrollment	All cause mortality
New York Heath Association (NYHA) functional class	Change from baseline at 3 time points over the year of follow up (3, 6, and 12 months)	NYHA functional class: I, III, III, or IV
Incidence of pleurodesis	1 year post-enrollment	Incidence of pleurodesis over the one year after enrollment will be measured. Pleurodesis is defined as apposition of the parietal and visceral pleural such: (i) that the subject drains less than 10cc on three serial drainages, (ii) there is resolution of the pleural effusion on both chest x-ray (CXR) and chest ultrasound, (iii) the TPC is removed, and (iv) the pleural effusion does not accumulate after TPC removal as evidence by CXR and chest ultrasound.
