Trial summary

The special fixation methodology of the Mosaic Ultra stented procine bioprosthesis allows valves to maintain their natural leaflet structure and root geometry which prevents leaflet calcification and improves hemodynamic performance and a potential for increased durability.

About this study

Official title: Mosaic Ultra Porcine Bioprosthesis - Hemodynamic Study

The special fixation methodology of the Mosaic Ultra stented procine bioprosthesis allows valves to maintain their natural leaflet structure and root geometry which prevents leaflet calcification and improves hemodynamic performance and a potential for increased durability. This study will document the hemodynamic performance, as assessed by echocardiographic recordings, at six months post implantation.

Read the detailed description

1.0 STUDY PLAN 1.1. Study Objectives The objective of this clinical study is to evaluate the hemodynamic performance of the Mosaic Ultra™ stented porcine bioprosthesis in the aortic position.

1.2. Study Design This will be a prospective non randomized multi center clinical study designed to obtain hemodynamic data on the Mosaic Ultra™ stented porcine bioprosthesis. All participating centers follow a common clinical investigation plan.

1.3. Sample Size and Study Duration The basis for this study will be at least 60 MosaicÒ Ultra™ stented porcine bioprosthesis implants followed for six months.

2.0 PATIENT SELECTION 2.1. Patient Eligibility Criteria The patient population includes all patients who require aortic valve replacement for heart valve disease (acquired or congenital) and who are candidates for a bioprosthetic valve. Patients will be informed about the aspects of this study and will be asked to give their Informed Consent. The patient population must be geographically stable and able to attend one follow-up examination at the implanting center. Patients not willing or unable to fully participate in the follow-up will not be entered in the study.

2.2. Inclusion Criteria

  • Patients who require aortic valve replacement with or without coronary artery bypass grafting or surgical treatment of Atrial Fibrillation.
  • Patients who are able to provide informed consent.

3.3. Exclusion Criteria

  • Concomitant procedures other than coronary artery bypass grafting or surgical treatment of Atrial Fibrillation.
  • Patients indicated for receiving a mechanical prosthesis.
  • Patients who will have a replacement of an existing valve prosthesis.
  • Patients refusing or not able to provide informed consent.
  • Patients requiring emergency surgery.

4.0 STUDY METHODS 4.1. Data Requirements For each patient enrolled in the study, information will be collected pre-operatively, operatively, and at 6 months post-operatively.

Patients entering the study are preoperatively evaluated for clinical information. Upon implant of the Mosaic bioprostheses the appropriate surgical data will be obtained. Follow-up data are required at discharge and six months post-operative. Endpoint for each patient in the study will be the six months follow-up.

The required variables are specified on each CRF. Samples of the CRF's are provided in Appendix C. Transthoracic echocardiography is required at pre-op and at six months.

All centers will be provided with a unique center ID. Enrolled patients will be identified on the CRF's by using the center ID with a sequential three digit number.

4.2. Case Report Form (CRF) Completion All appropriate sections of the case report forms must be filled out completely and accurately in black or blue ink. Before submission to Medtronic the investigator (or designated co-investigator) must review, sign and date the CRFs. The original is sent to Medtronic, and a copy remains at the center in the patient study file. All efforts should be made to submit CRFs to Medtronic within 6 weeks after the examination.

4.3. Study File A study file will be set up and maintained by the study center. This will be the repository for all records related to the study. All case report forms should be traceable to source documents. Source documents must be maintained in the patient medical records.

5.0 DATA ANALYSIS AND REPORTING 5.1. Data ownership All data collected in this study will be regarded as confidential and will be entered in a common database that is the property of Medtronic.

5.2. Data analysis Appropriate statistical analysis will be performed to compare the hemodynamic performance of various sizes. Hemodynamic data will be summarized by valve size. Descriptive statistics will be employed to report patient population characteristics, operative and post-operative data.

5.3. Data reporting Medtronic will complete and submit to the participating investigators a complete report using all collected data.

5.4. Publication policy It is the intent of both Medtronic and the study center that the investigator publish the results of this study. Medtronic may elect to use the data and outcomes of this study for the promotion of its products. Investigator will provide a copy of any abstract, presentation, and/or manuscript to Medtronic at least thirty (30) days prior to submission. Medtronic has the right to review the publications for confidential information, copyright materials and to edit for technical accuracy prior to submission.

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Valve Replacement and Coronary Artery Bypass Grafting, run by Medtronic Cardiac Rhythm and Heart Failure at 11 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Belgium, Germany, Israel, Austria, Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2015.
