Pericardial substitutes in thoracic surgery are not fully successful for reoperation. Polytetrafluoroethylene (PTFE) substitutes were more satisfactory than others, but caution and further studies are advised.

Area of Science:

  • Cardiothoracic Surgery
  • Biomaterials Science

Background:

  • Pericardial substitutes are used in thoracic surgery to mitigate reoperation risks.
  • Limited reports exist on the outcomes of these procedures.

Purpose of the Study:

  • To gather data on surgeon experiences with pericardial substitutes.
  • To document findings during reoperation in patients with these substitutes.

Main Methods:

  • A six-question survey was distributed to 2,344 members of The Society of Thoracic Surgeons.
  • 120 surgeons reported using 3,828 pericardial substitutes; 89 surgeons reported 236 reoperations.

Main Results:

  • No pericardial substitute was completely successful in facilitating reoperation.
  • Polytetrafluoroethylene (PTFE) substitutes showed significantly better outcomes than others (p=0.0004).

  • However, 14% of surgeons using PTFE reported dissatisfaction during reoperation.

    • Conclusions:

    • Widespread recommendation of pericardial substitutes requires caution.
    • Careful documentation and long-term follow-up studies are essential.
    • Further research is needed before routine adoption.
