Insights
Transxiphoid coronary artery bypass (CABG) offers a minimally invasive alternative to traditional sternotomy for left internal mammary artery (LIMA) to left anterior descending (LAD) revascularization. This approach avoids sternal division, reducing patient morbidity while maintaining bypass patency.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Procedures
Background:
- Coronary artery bypass grafting (CABG) via open sternotomy is a common procedure.
- Patients and clinicians seek alternatives to sternotomy for revascularization, particularly for left internal mammary artery (LIMA) to left anterior descending (LAD) artery bypass.
Purpose of the Study:
- To describe and evaluate a novel strictly transxiphoid mammary artery liberation with anastomosis to the anterior descending (TRAX CABG) technique.
- To assess the feasibility and success of TRAX CABG as a non-sternotomy alternative.
Main Methods:
- The study involved 26 patients undergoing attempted TRAX CABG.
- Eighteen patients successfully underwent non-sternotomy LIMA-to-LAD revascularization using the TRAX CABG technique.
- Completion angiography was performed to confirm bypass graft patency.
Main Results:
- Successful non-sternotomy LIMA-to-LAD revascularization was achieved in 18 out of 26 attempted TRAX CABG procedures.
- Conversion to traditional sternotomy was associated with limited unanticipated morbidity.
- Completion angiography confirmed the patency of the coronary artery bypass grafts.
Conclusions:
- TRAX CABG presents a viable, minimally invasive surgical option for LIMA-to-LAD revascularization in select patients.
- This technique avoids sternal division, potentially reducing surgical trauma and recovery time.
- The procedure demonstrates acceptable success rates with confirmation of bypass graft patency via angiography.
Abstract:
Revascularization of the coronary arteries, via open sternotomy and on cardiopulmonary bypass, remains the most common cardiac surgical procedure in the United States. Patients, and cardiologists, seek an alternative to dividing the sternum while reaping the advantages of left internal mammary artery (LIMA) revascularization of the diseased left anterior descending (LAD) coronary artery. We describe a strictly transxiphoid mammary artery liberation with anastomosis to the anterior descending (TRAX CABG) without sternal division. Of the 26 patients who underwent attempted TRAX CABG, 18 had nonsternotomy LIMA-to-LAD revascularization with completion angiogram to document bypass patency. TRAX CABG offers surgeons a minimally invasive alternative to trans-sternal LIMA-to-LAD in select patients. Conversion to traditional sternotomy has limited unanticipated morbidity and completion angiogram confirms procedural success.
