Ibutilideis less frequently used drug for atrial fibrillation (AF) in postoperative coronary artery bypass grafting (CABG) patients as compare to amiodarone. We therefore investigated the comparative efficacy of ibutilde and amiodarone for cardioversion in atrial fibrillation after CABG.To compare the efficacy of ibutilide and amiodarone for cardioversion of AF in post CABG patients. Narayana Multispeciality Hospital, Jaipur. Single center, randomized, double blind, comparative prospective study.Total 80 post CABG patients who developed AF were divided into two groups (Group A) Ibutilde and (Group B) Amiodarone respectively. The cardioversion time and cardioversion rate were measured. Unpaired t-test, Paired t-test, Chi square test / Fisher exact test. P value <0.05 The cardioversion rate at 4hrs in group A was 42.5% and in group B was 50% (p value > 0.001). At 24 hrs cardioversion rate in group A was 95% and in group B was 87.5% (p value > 0.001). The mean time of conversion to sinus rhythm in group A was 382.85 minutes and in group B was 492.30 minutes. (p value= 0.235)Ibutilide was as effective as amiodarone for restoration of sinus rhythm in postoperative coronary bypass grafting patients who developed atrial fibrillation in their postoperative intensive care unit stay. Ibutilide may be superior to amiodarone in terms of hemodynamics and systemic side effects.

Coronary artery stenosis bypass by using radial artery is good techniques which have longer outcomes. In coronary artery bypass grafting (CABG) the radial artery has several advantages. The radial artery has a thick muscular wall which is more susceptible to contraction from the competitive flow. As compared to the open harvesting technique endoscopic harvest of the radial artery has long lasting cosmetic results it also reduces the post-operative complications. The purpose of the study is to compare the two harvesting techniques and compare the short term and long term results related to intra-operative and post-operative outcomes Methods: This is retrospective study (In Queen Alia Heart Institute, Amman ,Jordan) to compare endoscopic radial artery technique versus open technique by reviewing patients files through a period between June 2013 and June 2018. Total 50 patients of CABG surgery was selected they were divided into two groups. Group A includes endoscopic radial harvest (n= 10) and Group B includes open harvest (n=40). Data was collected on predesigned Performa. Data were entered and analyze through IBM SPSS 22.0 Results: There was insignificant dissimilarity between the pre-operative outcomes between groups. The Post-operative outcomes were almost same in both groups except hand numbness (P-value<0.005). The comparison of intraoperative outcomes like harvest time between both groups indicate that the mean harvest time in group A was shorter than group B (39.20 + 3.73 Vs 51.90 + 2.09, P-value=0.000). The operative time in group A was higher than the group B (306.0 + 11.6 Vs 278 + 4.25 p-value=0.00). The hospital stays in both groups were insignificantly different (p = 0.09) Conclusions: Endoscopic radial artery harvest is best suited technique for CABG surgery as it significantly decreases the harvest time as well as hospital stay. It is also proven that it is safer, less painful and better wound appearance technique with exceptional outcomes based on positive surgical experience.

Artery Bypass Grafting

Background: Postoperative atrial fibrillation (pAF) after coronary artery bypass grafting is a common complication. Whether pAF is associated with an increased risk of cerebrovascular accident (CVA) remains uncertain. We investigated the association between pAF and long-term risk of CVA by performing a post hoc analysis of 10-year outcomes of the ART (Arterial Revascularization Trial). Methods: For the present analysis, among patients enrolled in the ART (n=3102), we excluded those who did not undergo surgery (n=25), had a history of atrial fibrillation (n=45), or had no information on the incidence of pAF (n=9). The final population consisted of 3023 patients, of whom 734 (24.3%) developed pAF with the remaining 2289 maintaining sinus rhythm. Competing risk and Cox regression analyses were used to investigate the association between pAF and the risk of CVA. Results: At 10 years, the cumulative incidence of CVA was 6.3% (4.6%–8.1%) versus 3.7% (2.9%–4.5%) in patients with pAF and sinus rhythm, respectively. pAF was an independent predictor of CVA at 10 years (hazard ratio, 1.53 [95% CI, 1.06–2.23]; P =0.025) even when CVAs that occurred during the index admission were excluded from the analysis (hazard ratio, 1.47 [95% 1.02–2.11]; P =0.04). Conclusions: Patients with pAF after coronary artery bypass grafting are at higher risk of CVA. These findings challenge the notion that pAF is a benign complication.

Background: Obesity affects cardiovascular morbidity and mortality, and it increases the risk of coronary artery disease. Despite that, several cardiac surgery risk stratification scores do not consider the effect of obesity on the outcomes. The objective of this research is to study the impact of body mass index (BMI) on morbidity and mortality after coronary artery bypass grafting (CABG) in Egyptian patients. Methods: This prospective cohort study included 200 patients who underwent CABG for atherosclerotic coronary artery disease. Patients were divided into two groups, group A: patients with BMI ≥ 25 Kg/m2 and group B: patients with BMI < 25 Kg/m2. The mean age in group A was 56± 4.95 years vs. 54± 5.5 years in group B (p= 0.102). Male patients presented 58% of the population in group A vs 74% in group B (p= 0.017). 60% of patients were hypertensive in group A compared to 63% in group B (p= 0.66) and 62%, and 48% were diabetics in group A and B respectively (p= 0.04). Results: Postoperatively, there was a significant increase in wound infection (40% vs 8%; p< 0.001), chest infection (47% vs. 10% p< 0.001), surgical re-exploration (28% vs. 1%; p< 0.001), prolonged ICU stays (5.3 ± 2.88 vs. 3.93 ± 1.71 days; p< 0.001), ward stay (11.28 ±8.9 vs. 5.48 ± 2.45 days; p< 0.001), mediastinitis (34% vs. 6%; p< 0.001), the occurrence of sternal wound sinus within 8 months (26% vs. 7%; p< 0.001), in group A more compared to group B. There was no difference in ejection fraction (54.2 ±7.38 vs. 54.7 ± 9.1%; p= 0.69) and mortality (4% vs. 2%; p= 0.68) between groups. Conclusions: BMI 25 Kg/m2 or higher is associated with increased infectious complications and prolonged stay after CABG; however, it did not affect mortality. Optimizing body weight is recommended before elective surgery.

Background: To evaluate the effect of minimally invasive direct coronary artery bypass (MIDCAB) simulator for cardiac residency training. Methods: A total of 26 resident surgeons who had never trained for coronary artery anastomosis participated in this training program. They received coronary artery anastomosis training on off-pump coronary artery bypass grafting (OPCAB) simulator for 15 h. After training, their performance of anastomosis was evaluated on the OPCAB simulator according to 12 items and a 5-point global rating scale. Based on the total score of assessment, those with an individual score of 12-36 formed group A, while group B was composed of the remaining trainees. The two groups then received another 15 h coronary artery anastomosis training on the MIDCAB simulator, and the performance was assessed. Results: Trainees improved their performance of coronary artery anastomosis after training on the OPCAB simulator. Group A was composed of 7 trainees with an individual with a total score of 12–36 points and group B was composed of the remaining 19 trainees. After MIDCAB simulator training, significant differences were noted in the pre- and post-training values in the A group (P < .001), and the assessment value of group A was significantly better than those of group B (P < .05). No significant difference was detected between pre- and post-training values in group B after MIDCAB simulator training (P > .05). Conclusion: We concluded that trainees who performed well in OPCAB simulation training can also perform better in MIDCAB, and our designed MIDCAB simulator was useful for residency training.

Objective: Minimal invasive extracorporeal circuits (MiECC) have been associated with a significant reduction in the incidence of postoperative atrial fibrillation (AF). Nevertheless, AF remains one of the most common complications following elective primary coronary artery bypass grafting (CABG). The aim of this study was to identify the predictors of AF persisting beyond the hospital stay in elective primary CABG patients. Methods: We conducted a retrospective analysis for the predictors of AF that persisted beyond discharge between all patients who received an elective isolated CABG in our institution between 2009 and 2014. Patients with a positive history for intermittent or persistent AF were excluded from the analysis. Almost all patients were discharged to a rehabilitation facility where they stayed for 3 to 4 weeks postoperatively. At rehab approximately 91% of them received Holter monitoring at least once prior to their discharge. Results: A total of 770 patients were included in the analysis of which 763 patients survived the in-hospital stay. The incidence of AF at hospital discharge was 4.2% (32/763) while that on Holter monitor at Rehab was 1.5% (10/685). Age and the type of extracorporeal circuit (ECC) utilized were the only significant predictors for both AF at discharge ( p < 0.01 both) and on Holter monitor in rehab ( p < 0.01 and 0.02, respectively). This was also confirmed on multivariate analysis. Conclusion: Our findings show that the benefits of MiECC regarding the incidence of postoperative AF persist beyond hospital discharge. They may thus positively influence the outcomes of patients beyond the early postoperative period.

Risk Of Death

Abstract Purpose To assess the prevalence of frailty in the preoperative period and to evaluate its effect on the risk of complications and adverse outcomes in patients undergoing coronary artery bypass grafting (CABG). Methods 303 patients undergoing preoperative management for elective primary CABG were recruited in the study. The study cohort was divided into three groups depending on the PRISMA-7 scores suggesting the presence or absence of frailty and the presence of prefrailty. Statistical analysis was performed using the commercially available software package STATISTICA 8.0.360.0 for Windows (StatSoft, Inc., USA) and SPSS Statistics v. 17.0.0. Results 46 (15%) patients had frailty, while 49 (16%) patients were diagnosed with prefrailty. 208 (69%) patients did not have any signs of frailty. All three groups had significant age differences, therefore only elderly patients aged of 67.0±6.5 years with frailty were allocated for subsequent analysis (prefrailty group - 62.3±7.4 years old, patients without frailty - 60.0±7.7 years, p=0.003). Patients with frailty or prefrailty more often suffered from diabetes mellitus (patients without frailty - 19.2%, prefrailty group - 30.6% and frailty group - 28.3%, p=0.05), arterial hypertension (69.2%, 93.9% and 95.7%, respectively, p&lt;0.001), atrial fibrillation or flutter (7.2%, 14.3% and 19.6%, respectively, p=0.03), chronic heart failure class 3–4 (7.2%, 10.2% and 8.7%, respectively, p=0.002), and peripheral arterial disease (22.6%, 38.8% and 58.7%, respectively, p&lt;0.001). Three groups were comparable in main clinical and demographic parameters. There were no significant differences found in the incidence of postoperative atrial fibrillation or flutter (15.9%, 8.2% and 6.5%, respectively, p=0.07) and infections (1.9%, 0% and 4.3%, respectively, p=0.640). The incidence of myocardial infarction in the intra- and early postoperative period after CABG did not differ significantly between the groups (0.5%, 2% and 0%, respectively, p=0.328) as well as the incidence of stroke (2.4%, 2% and 0%, respectively, p=0.640). Patients with frailty and prefrailty had significantly higher cerebrovascular and cardiovascular mortality compared to those without frailty (8.2%, 2.2% and 0.5%, respectively, p=0.001). Conclusion Almost 15% of patients referred to CABG suffered from frailty. The presence of prefrailty or frailty increases the risk of death in the early postoperative period after CABG.

Hba1c Levels

Background Diabetes is associated with higher mortality and worse post-operative outcomes in patients undergoing coronary artery bypass grafting and HbA1c levels have consistently been reported to be associated with adverse post-operative outcomes. However, the role of HbA1c still remains unclear with regards to the occurrence of atrial fibrillation. Method Data for the patients undergoing off-pump coronary artery bypass grafting was analysed in a retrospective fashion. Patients were divided into–those with HbA1c < 6.5% and those with HbA1c ≥ 6.5% and the incidence of atrial fibrillation observed in these two groups. We also compared patient who developed atrial fibrillation in the post-operative period and compared them with those who did not. Results Of the 5259 patients included in the study HbA1c was <6.5 in 2808 (53.4%) patients and was ≥6.5 in 2451 (46.6%) patients; 623 (11.8%) patients in our study developed atrial fibrillation. Onset of atrial fibrillation in the post-operative period was seen most commonly 235 (38.3%) on between 24 and 48 h after the operation with more than half of them 338 (54.2%) occurring within the first 48 h. On multivariate analysis, HbA1c was not a risk factor for atrial fibrillation (odd’s ratio 1.144, 95% confidence interval 0.967–1.354). Only increased age (odd’s ratio 1.08; 95% confidence interval 1.069–1.091); EuroSCORE (odd’s ratio 1.073; 95% confidence interval 1.048–1.099); history of recent MI (odd’s ratio 0.768; 95% confidence interval 0.606–0.971) and peripheral vascular disease (odd’s ratio 1.667; 95% confidence interval 1.091–2.517) were found to be independently associated with increased risk of atrial fibrillation in the post-operative period. Conclusions After adjusting for confounders HbA1c levels do not independently predict risk of atrial fibrillation after off-pump coronary artery bypass grafting.
