FIT Clinical Decision Making A RIGHT CORONARY ARTERY BYPASS DILEMMA: COMBINED CORONARY ENDARTERECTOMY WITH CORONARY BYPASS SAVED THE DAY Poster Contributions Poster Area, South Hall A1 Sunday, April 03, 2016, 9:45 a.m.-10:30 a.m. Session Title: FIT Clinical Decision Making: Acute Coronary Syndrome, Stable Ischemic Heart Disease, Interventional Cardiology, Vascular Medicine Abstract Category: Acute Coronary Syndromes Presentation Number: 1185-281 Authors: Muhanad Al-Zubaidi, K. H. Lim, Wright State University, Dayton, OH, USA, Premier Health- Good Samaritan Hospital, Dayton, OH, USA
Background: The increasing incidence of diffuse coronary artery disease in the current era challenges cardiac surgeons in accomplishing their goal of complete revascularization. Controversy still exists for CE indications, technique, and results. The purpose of this presentation is to highlight the feasibility and comparable success of CE to the RCA.
Abstract: An 82 year-old female underwent coronary angiogram for ongoing angina, which showed severe disease of the left main and LAD and total RCA occlusion. She was referred for coronary bypass surgery and had LIMA bypassed to LAD and saphenous vein graft (SVG) to the first optimal marginal branch and diagonal branched of the LAD. Intra-operatively, the RCA was calcified and there was no soft area to construct the distal anastomosis. We were forced to perform endarterectomy of the RCA with its posterior descending branch and the posterolateral branch of the RCA. SVG was bypassed to RCA. Seven months later, a repeat coronary angiogram showed patent SVG to RCA. Conclusions: High morbidity and mortality have been reported with CE. This makes surgeons tend not to endarterectomize the diffusely diseased RCA and most prefer not to bypass this artery in such situation. On the other hand, many studies showed accepted safety with CE with no increase hospital mortality have been reported. Combined RCA CE with coronary artery bypass grafting had favorable outcome in previous series and one study demonstrated no statistically significant mortality and morbidity differences in one study comparing RCA EC to bypass than these without RCA CE. Finally, CE offers an alternative option of coronary artery reconstruction and revascularization when technically unable to construct distal anastomosis. Conclusions: RCA endarterectomy can offer satisfactory result for patients with diffused coronary artery disease. As there is no uniform agreement amongst surgeons in the field of CE, a large prospective trial is needed to establish guidance and outcomes.
