摘要

BACKGROUND: Target vessel revascularization on a beating heart via a mini subxiphoid incision, not only eliminates the hazards of sternal reentry, but also avoids the detrimental systemic effects of extracorporeal circulation. AIM: The goal of the study was to develop and describe a safe and effective method to revascularize the right coronary artery in reoperative cases, using beating heart and minimally invasive techniques in lieu of the RGEA. METHODS: There were three men and four women with a mean age of 69 years; four were second time reoperations and three third time reoperations. Through a subxiphoid approach, a lower ministernotomy is performed. Once the coronary target is established, a Rultract retractor is used to gently elevate the right half of the sternum to take down the RITA. A mechanical stabilizer was used to provide stabilization for distal anastamoses. Flow was measured in all the grafts with the Medi-Stim before and after protamine administration. RESULTS: [table: see text] CONCLUSION: We believe that this technique provides another effective approach to the patient who requires reoperative coronary revascularization of the RCA.
