SuperCable vs. steel wires for closing the sternum after heart surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study compares two methods for closing the sternum after CABG: SuperCable and conventional steel wires. Participants are randomly assigned to one of the two closure methods and followed for healing, pain, and postoperative complications. Outcomes are assessed at 3 and 6 months postoperatively, with a focus on sternal stability, recovery, and patient-reported satisfaction. The trial aims to determine if the iso-elastic SuperCable system improves recovery relative to standard wires. The study is conducted at the University Hospital Zurich with 86 enrolled participants.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Provision of Informed Consent: The subject must have signed and dated the informed consent form prior to any study-related procedures.
* Willingness and Ability to Comply: The subject must express a stated willingness to comply with all study procedures and be available for the duration of the study.
* Age and Sex:

  * Age: The subject must be at least 18 years old.
  * Sex: Both male and female subjects are eligible. In line with the "Sex and Gender in Research Involving Humans" recommendations, data will be stratified and analyzed by sex to identify any potential differences in outcomes.
* Language Competence: The subject must possess sufficient German language skills to accurately complete the postoperative survey
* Travel Capability: The subject must have the ability to travel for all planned study visits, including scheduled CT scans
* Surgical Procedure: The subject must be scheduled for elective coronary artery bypass graft (CABG) procedures, as this is the focus of the investigation
* Adherence to Visit Schedule: The subject must be willing to adhere to all scheduled visits and undergo CT scans as outlined in the study protocol

Exclusion Criteria:

* Pharmacological Restrictions: Current use of corticosteroids or any immunosuppressive medication
* Prior Treatments and Therapies: History of radiation therapy to the thorax
* Reproductive Considerations:

  * Pregnancy, or the intent to become pregnant during the study period
  * Lactation or current breastfeeding
* Allergic Reactions: Known allergic reactions to components of the conventional steel wire or SuperCable, specifically any known metal allergies (e.g., nickel or titanium).

Example: Patients with a documented history of nickel allergy, including previous adverse reactions to products such as sternal cerclages, will be excluded

* Infectious or Febrile Conditions: Any febrile illness occurring immediately before the scheduled surgery
* Concurrent Investigational Treatments: Treatment with another investigational drug or medical device within two months preceding surgery, as well as during the current investigation
* Surgical History: Subjects who have undergone prior sternotomy and osteosynthesis (i.e., re-do patients) will be excluded
* Anatomical Considerations:

  * Known sternal deformities that could compromise the outcome of the investigation
  * Off-midline sternotomy approaches, as these do not align with the surgical technique under investigation
* Patient Residence and Follow-Up Feasibility: Subjects residing in remote regions, including those from interstate or overseas, where follow-up and adherence to the scheduled visits might be compromised
* Other Specific Exclusions: Any additional criteria specific to the disease under investigation or identified by the investigator based on medical judgment (e.g., clinically significant concomitant disease states such as renal failure, hepatic dysfunction, or cardiovascular disease, if these conditions are deemed to interfere with study outcomes)
