[Computer-assisted reconstruction of coronary vessels]

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Imaging

Background:

• End-stage coronary artery disease with linear stenosis presents significant surgical challenges.
• Conventional revascularization with grafts often yields inadequate long-term results due to underlying coronary vessel pathology.
• Existing treatments struggle with complex, multi-vessel blockages unresponsive to repeated interventions.

Purpose of the Study:

• To explore a novel surgical approach for complex coronary artery disease.
• To evaluate the potential of 3D-reconstruction guided selective thrombendarteriectomy (TEA).
• To investigate intraoperative brachytherapy as a method to mitigate neointimal hyperplasia post-TEA.

Main Methods:

• Development of precise 3D-reconstruction techniques for coronary vasculature.
• Application of selective thrombendarteriectomy (TEA) based on 3D imaging.
• Intraoperative brachytherapy administration to inhibit neointimal proliferation.

Main Results:

• 3D-reconstruction enables detailed visualization for targeted TEA.
• Selective TEA demonstrates potential for addressing complex linear stenoses.
• Intraoperative brachytherapy shows promise in controlling neointimal hyperproliferation.

Conclusions:

• 3D-reconstruction guided TEA represents a promising advancement in treating complex coronary artery disease.
• Intraoperative brachytherapy may be a crucial adjunct to TEA for improving long-term outcomes.
• Further research is warranted to validate the efficacy and safety of this combined approach.
