Insights
Hybrid coronary revascularization (HCR) combines surgical bypass and percutaneous procedures. Modifying the surgical approach and timing of percutaneous intervention can increase HCR adoption for multivessel coronary artery disease.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
Background:
- Hybrid coronary revascularization (HCR) integrates surgical and percutaneous coronary revascularization but faces limited adoption.
- Current HCR protocols often involve technically demanding minimally invasive surgery and specialized hybrid operating rooms.
Purpose of the Study:
- To review current Hybrid coronary revascularization protocols.
- To identify barriers to widespread Hybrid coronary revascularization adoption.
- To propose modifications to facilitate Hybrid coronary revascularization use.
Main Methods:
- Review of existing Hybrid coronary revascularization protocols and literature.
- Analysis of surgical approaches, specifically the left internal mammary artery (LIMA) graft to the left anterior descending artery (LAD).
- Evaluation of the timing of percutaneous coronary revascularization relative to surgical intervention.
Main Results:
- The minimally invasive surgical approach for Hybrid coronary revascularization is technically challenging.
- Limited availability of hybrid operating rooms restricts same-day percutaneous coronary revascularization.
- A median sternotomy approach for LIMA-LAD grafting combined with delayed percutaneous revascularization is suggested.
Conclusions:
- Modifying the surgical approach to median sternotomy for LIMA-LAD grafting can simplify the procedure.
- Delaying percutaneous coronary revascularization may overcome logistical barriers.
- These modifications could promote wider adoption of Hybrid coronary revascularization for suitable patients with multivessel coronary artery disease.
Abstract:
Combined surgical and percutaneous coronary revascularization, ie, hybrid coronary revascularization (HCR) consists of surgical left internal mammary artery (LIMA) bypass to the left anterior descending artery (LAD) and percutaneous revascularization of other diseased coronary arteries. Developed as a 1-stage procedure, HCR has not been widely adopted by the cardiovascular community. The recommended minimally invasive approach through a small left thoracotomy incision is technically demanding, and same-day percutaneous revascularization requires a hybrid operating room that is not available in most hospitals. In this review, we consider present HCR protocols, barriers to widespread adoption of HCR, and we give special attention to the surgical approach for the LIMA graft to the LAD and the timing of percutaneous revascularization. We conclude that grafting the LIMA to the LAD through a median sternotomy approach and delaying the percutaneous revascularization may facilitate the widespread use of HCR in patients with multivessel coronary artery disease and a low to intermediate Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score.
