Cardiovascular and Thoracic Surgery
Cardiovascular and Thoracic Surgery is one of the most advanced and high‑acuity specialties in the operating room. CSTs in this service line support cardiac, vascular, thoracic, endovascular, and transplant procedures, working closely with surgeons, perfusionists, anesthesia teams, and specialized nursing staff. This specialty demands precision, anticipation, and mastery of complex instrumentation used to operate on the heart, lungs, and major vessels.
CVOR Subspecialties
Overview of the CVOR Service Line
CSTs in the Cardiovascular and Thoracic service line support cardiac, vascular, thoracic, endovascular, and transplant procedures as a unified specialty. These cases share instrumentation, workflows, and team structure, which is why most hospitals group them into a single CVOR department.
Cardiac Surgery
Includes CABG, valve repair and replacement, aortic root procedures, LVAD implantation, ECMO cannulation, and other open-heart operations.
Vascular Surgery
Includes open vascular procedures such as carotid endarterectomy, abdominal aortic aneurysm repair, femoral‑popliteal bypass, and peripheral vascular reconstruction.
Endovascular Surgery
Includes stent placement, EVAR/TEVAR, angiography, hybrid OR workflows, radiation safety, imaging equipment operation, and wire/catheter handling.
Thoracic Surgery
Includes lobectomy, pneumonectomy, thoracotomy, VATS procedures, chest wall reconstruction, and mediastinal mass excision.
Transplant Surgery
Includes heart and lung transplantation, with occasional multi‑organ involvement depending on the facility.
Where These Procedures Are Performed
Most hospitals perform these cases in a dedicated CVOR or hybrid OR. Smaller hospitals may perform them in general ORs depending on staffing, equipment, and case volume
Role of CSTs
- Prepare the CVOR or hybrid OR with cardiac, vascular, thoracic, and endovascular instrumentation and supplies.
- Assist with patient positioning, prepping, and draping for sternotomy, thoracotomy, and minimally invasive approaches.
- Maintain strict sterile technique during high‑risk procedures involving the heart, lungs, and great vessels.
- Anticipate surgeon needs during cannulation, grafting, vessel exposure, and cardiopulmonary bypass setup.
- Manage specialty instruments such as vascular clamps, sternal saws, coronary sets, and endovascular devices.
- Handle graft materials, sutures, and implants used in cardiac and vascular reconstruction.
- Support perfusion and anesthesia teams during bypass initiation, hemodynamic monitoring, and emergency interventions.
- Assist with specimen handling, device tracking, and accurate surgical counts in complex multi‑team cases.
Essential Skills
- Mastery of cardiac, vascular, thoracic, and endovascular instrumentation and specialty trays.
- Proficiency in setting up and maintaining a sterile field during high‑acuity procedures.
- Ability to anticipate surgeon needs during rapid, high‑risk phases such as cannulation or vessel clamping.
- Strong understanding of cardiovascular anatomy, graft types, and implantable devices.
- Competence with hybrid OR workflows, imaging equipment, and radiation safety.
- Skilled in handling delicate tissues, micro‑instruments, and fine sutures used in vessel repair.
- Ability to assist during emergencies such as cardiac tamponade, aortic rupture, or massive hemorrhage.
- Effective communication with surgeons, perfusionists, anesthesia, and nursing teams.

Sterile Technique Considerations
- Maintain strict sterility during cannulation, graft handling, and bypass setup.
- Protect sterile fields during imaging equipment movement in hybrid ORs.
- Use radiation protection while preserving sterile technique during endovascular procedures.
- Handle grafts, implants, and micro‑instruments with precision to avoid contamination.
- Maintain sterility during long, multi‑team procedures with frequent equipment changes.
- Ensure proper management of anticoagulated patients with high bleeding risk.
