Brief Summary

Postoperative bleeding is a common consequence after heart surgery which can significantly impact outcomes and costs . When bleeding occurs, reliable postoperative blood evacuation of the pleural, mediastinal and pericardial spaces with chest tubes is imperative to facilitate pulmonary reexpansion and mediastinal decompression as the patient recovers. When postoperative blood evacuation is inadequate, complications from retained blood can result. Clinically, retained blood may be recognized acutely or sub acutely. The acute clinical presentation is usually blood and fresh thrombus around the heart or lungs presenting as tamponade or hemothorax. The subacute clinical presentation is bloody pleural or pericardial effusions. These effusions are often driven by the breakdown of remaining thrombus. Once retained blood occurs, subsequent procedures may be needed to remedy it. Interventions to remove postoperative pericardial and/or pleural fluid or blood and reoperations due to bleeding are captured under a composite termed Retained Blood Syndrome, or RBS. The need for treatment and interventions for these conditions represents an impediment to patient recovery and involves both resource and economic consumption for a heart program and the healthcare system at large.

A recent review of the literature indicates that additional procedures for RBS are demonstrated in approximately 15% to 20% of patients after heart surgery. In a prospectively collected US Nationwide Inpatient Sample (NIS) data from 2010, RBS could be demonstrated in 17% of patients. In this analysis, mortality was doubled from 4% to 8%, length of stay was increased by 5 days, and average costs were 55% higher. Patients with RBS, therefore, represent an increased at-risk population for complications and costs.

Postoperative obstruction of conventional chest tubes with blood and other fibrinous material in the setting of postoperative bleeding contributes to RBS. In a study of postoperative cardiac surgery patients at the Cleveland Clinic, 36% of patients were found to have evidence of chest tube obstruction. Active Clearance with PleuraFlow has been shown to prevent chest tube clogging, and reduce RBS.

The purpose of this registry is to evaluate the effectiveness of the PleuraFlow System, a commercial Class II (US), Class IIb (Canada, Europe, and Australia), in the management of blood evacuation after cardiac surgery.

Detailed Description

This is a prospective multicenter observational registry with a retrospective control. The registry has two tracks. One track--ALL-ACT-- is for sites enrolling a consecutive cohort of all cardiac surgery patients (Track A). The second track--VAD-ACT-- is for sites enrolling patients post ventricular assist device (VAD) surgery (Track B). There are two conditions for participation in this registry:

First, sites are required to provide anonymized matched historical data elements from a cohort of cardiac surgery patients done over the preceding 12 to 24-month period (Phase 0). These retrospective data elements will be used as baseline information for the purpose of comparative analyses (control group) with the prospective data sets collected during the prospective enrollment phase (treatment group).

Second, sites are required to participate in a roll-in phase (Phase 1). The purposes of the roll-in phase are to allow the users at participating sites to familiarize themselves with the use of the product with Active Clearance Technology; to implement clinical use protocols provided by ClearFlow, Inc. to all commercial users as part of product training, and; to demonstrate consistency and compliance with the clinical use protocols.

Phase 0 and phase 1 can be executed in parallel. Participating sites may start prospective enrollment (Phase 2) after completion of phase 0 and 1.

Investigators shall report PleuraFlow-related serious injuries to Sponsor as soon as becoming aware of the injury and no later than 48 hours.

Investigators shall report deaths to both the Sponsor and Regulatory authorities in compliance with their applicable State, Country and conditions imposed by the reviewing Ethical Committee. The three main guidance documents for reporting recall and vigilance procedure of medical devices are, 21 CFR, Part 806, MEDDEV 2.12/1 rev8 Guidelines on a Medical Devices Vigilance System, and Health Canada Medical Device Regulations SOR/98-282.

Vanderbilt University will create a REDCap database specific to this study and administer it. The Vanderbilt database study administrator will control database access, oversee data entry and data transfer from each participating site. Database manager will monitor the REDCap database and ensure data completeness and security. The database manager will maintain contact will the data entry personnel from each site and ensure whether data capture is occurring and determine the number of patients expected to be enrolled in the Registry at the end of the study period. Sponsor will not have access to REDCap once the study is complete. The REDCap database is secure and HIPAA compliant.

Descriptive statistics for categorical variables will be reported as percentages, and continuous variables will be reported as mean ± standard deviation (SD). Categorical variables will be compared using the chi-square test. Continuous variables will be compared using a Student's t-test as appropriate.

Database study administrator will coordinate the generation of data reports and statistical outputs. Sponsor will not have access to REDCap once the study is complete.
