  • Transabdominal approach in redo coronary artery bypass grafting(CABG) may avoid the risk related to repeat sternotomy. Redo CABG using this approach can be performed safely in selected cases. We report a case of redo off-pump CABG through a transabdominal approach in a 59-year-old woman with recurrent unstable angina after a previous CABG. Through a curvilinear epigastric incision, right gastroepiploic artery(RGEA) was harvested as a graft, and the RGEA-to-right coronary artery anastomosis was performed on the beating heart. A 1-day postoperative angiographic study showed the patent RGEA graft, and she was discharged on postoperative 4th day without any complication.

  • The incidence of reoperative coronary artery bypass grafting (CABG) has increased because of the rise in the number of patients who have undergone initial CABG. In addition, recent technological advances have resulted in widespread application of off pump coronary artery bypass (OPCAB). We report a case of redo OPCAB through thoracotomy and small laparotomy in 76-year-old man with recurrent unstable angina.

  • Recently, the number of coronary artery bypass surgery(CABG) is increasing according to the increasing incidence of coronary artery disease. However, CABG is not a definite corrective surgery; therefore, in some patients, redo-CABG may be required. We retrospectively reviewed our redo-CABG experiences to help future redo-CABG. Material and Method: From January 1991 to April 2001, 14 cases of redo-CABG were performed in Yonsei Cardiovascular Center(M:F=12:2) and mean age was 61,7 $\pm$ 7.1(47-72) years. Mean time from 1st. CABG to redo-CABG was 121.9 $\pm$ 50.5(6.1-179.6) months. Thirteen cases were conventional on-pump CABG and one case was off-pump CABG. In two patients, mitral valve re-replacement and mitral valve repair were performed each. All redo-CABG were performed through mid-sternotomy. During redo-CABG, left internal mammary artery and saphenous vein grafts were used in 6 patients, left internal mammary artery and left radial artery grafts were used in 2 patients, left internal mammary artery and gastroepiploic artery were used in one patient and only greater saphenous veins were used in 5 cases(In one case, cephalic vein was also used). The number of mean distal anastomosis was 2.1 $\pm$ 0.9(1-4). Result: There were no operative death and no perioperative myocardial infarctions and cerebrovascular accidents or other heart related complications. Mean follow up duration was 40.1 $\pm$ 38.6(1.1-118.5) months. During follow up period, angina was re-developed in one patient 13 months after operation. Two patients died of end-stage renal failure 14.8 months and 116.3 months after redo-CABG, respectively. During follow up period, coronary angiography was performed in 3 patients, and all grafts were patent. At last follow up, mean Canadian class was 1.3. Kaplan-Meier survival at 9 years was 90.0 $\pm$ 9.5% and event free survival at 9 years was 71.4 $\pm$ 6.9%. Conclusion: After redo-CABG, all patients improved their angina symptom and daily activity. And long-term survival after redo-CABG was excellent. Therefore, if patients have indications for redo-CABG, thenredo-CABG must be strongly recommended and performed.

  • As the experience of coronary artery bypass grafting (CABG) has been accumulated, the number of reoperation after CABG is increasing. We analyzed our clinical experience of redo-CABG. Material and Method: Fourteen patients who underwent redo-CABG between Jan. 1994 and Dec. 2002 were included in this study. The mean period from the first operation to reoperation was 66$\pm$56 (3∼157) months, and the average ages were 62.8$\pm$8.7 (51∼78) years. The survivors were followed up 39$\pm$29 (4∼101) months postoperatively. Indications of reoperation were stenosis or occlusion of previous grafts in 11 patients, progression of native coronary artery disease in one patient, and both etiologies in two patients. Result: There were two in-hospital mortalities (14.3%) resulting from low cardiac output syndrome, Postoperative morbidities were perioperative myocardiac infarction in 2 patients (14.3%), mediastinitis in one patient (7.2%), duodenal perforation in one patient, ischemic necrosis of the lower extremity in one patient, gastric perforation after mesenteric infarct in one patient, delayed brain infarct in one patient, and intraoperative splenic rupture in one patient. There was one late mortality at six months postoperatively during the follow up. There was no angina recurrence during the follow up. Conclusion: Although redo CABG demonstrated relatively high operative mortalities and morbidities, postoperative status and clinical outcome of the survivors were favorable.

  • We report there on a 46-year-old male patient whose angina recurred after a coronary bypass graft (CABG). Occlusion of the first diagonal branch was found on performing a coronary angiogram (CAG), and this occlusion had not previously been present. So, a redo-off pump CABG was performed via a left posterolateral thoracotomy. The anastomosis was made between the descending thoracic aorta and the diagonal branch by using the right radial artery. On the Multi-detector computerized tomography (MDCT) coronary angiogram conducted after the operation, it was confirmed that there was no abnormality in the anastomosis site. A Redo-CABG was successfully performed via left posterolateral thoracotomy in the patient whose disease was only at the diagonal branch.

  • It is now widely accepted that the complete arterial coronary revascularization has better short and long term results compared to coronary bypass surgery using arterial graft mixed with vein graft mainly due to its superior patency rate. However, sometimes the internal thoracic artery and other conventionally used grafts might be unavailable or it may require caution in using bilateral internal thoracic artery especially in diabetic patient because of the possible risk of the mediastinitis or other associated morbidities. Moreover, there could also be a shortage for arterial graft in case of coronary reoperation. We report our first three cases using thoracodorsal artery(TDA) as an alternative graft in complete arterial coronary revascularization.

  • This study was conducted to evaluate the clinical outcomes of coronary artery bypass surgery for ischemic heart disease according to use of a cardiopulmonary bypass machine. The subjects were 10,981 patients who underwent coronary artery bypass grafting for ischemic heart disease from July 2008 to June 2012. Analysis data were retrospectively collected using health insurance claims data. The results of the study showed that mean time to surgery (280 min vs 357 min, p<0.0001) and intubation time (about 24 hours vs 40 hours, p<0.0001) were significantly shorter in the Off-Pump CABG (OPCAB) group than in the On-Pump CABG (ONCAB) group. The rate of reoperation because of postoperative bleeding and hematoma was lower in the OPCAB group (2.7% vs 8.3%, p<.0001). The odds ratio of risk adjusted 30 days mortality rate was 0.339 (0.266-0.434) and the postoperative length of stay was decreased in the OPCAB (p<0.0001). Overall, the 30 days mortality and reoperation rates were lower in the OPCAB, as was the resources use.

  • Background: Although the reports on re-operative coronary revascularization (redo-CABG) have increased, there are only limited reports on redo-CABG using arterial grafts. The aim of this study was to analyze the safety and feasibility of using various arterial grafts for redo-CABG. Material and Method: A consecutive series of patients who underwent 33 redo-CABGs from March 2001 to July 2008 were retrospectively reviewed. We performed conventional CABG in 17 patients, on-pump beating CABG in 7, off-pump CABG in 7 and minimally invasive direct coronary artery bypass in 2. The grafted that were used included 34 internal thoracic arteries (ITA), 14 radial arteries, 14 right gastroepiploic arteries and others. Arterial composite grafts were constructed in 26 patients. Of these, a previously patent in-situ left ITA was re-used as the in-flow of a composite graft in 10 patients. Result: No hospital deaths or major wound problems occurred. The post-operative complications included 2 myocardial infarctions (6%), 1 intra-aortic balloon pump insertion (3%), 5 cases of atrial fibrillation (15.1 %) and 3 neurologic complications (9.1%). The meanfollow-up duration was 31.1$\pm$22.7 months and the 3 year survival rate was 86.4%. There were 4 late deaths (2 cardiac deaths) and no recurrent angina during the follow-up period. Conclusion: Redo-CABG with using various arterial grafts is currently a safe, feasible procedure, but further investigation and long term follow-up are needed.
