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.
