Objective. To assess the performance of tomographic ultrasonography (TUS) in providing images that will enable optimum choice of vein segment to harvest for coronary artery bypass grafting (CABG). Methods. This was a prospective study of diagnostic accuracy. The index test was tomographic ultrasonography. The reference standard was intraoperative observation. The study was performed at the Vascular Imaging and Cardiothoracic Department at Wythenshawe Hospital, Manchester. Patients undergoing CABG who require vein mapping were included in the study. The main outcome measures were the number of tributaries identified in harvested vein segments, presence of varicosities, and usable length of vein. Results. The TUS correctly identified 89 out of 111 vein tributaries in 10 patients resulting in a sensitivity of 80.2%. This resulted in a p value of 0.000001 using an exact binomial test, with a prior probability of 0.5. TUS had a sensitivity of 66.7% and a specificity of 100% in the identification of varicosities over 14 patients. TUS had 90% agreement with intraoperative observation in assessing usable length of vein over 14 patients. Conclusions. Our results show that TUS has a high sensitivity in identifying vein tributaries. This can be used to select veins with fewer tributaries for harvesting should TUS be used for preoperative vein mapping before CABG.

Abstract Background The development of acute kidney injury (AKI) is an important indicator of clinical outcomes after cardiac surgery. Elevated preoperative hemoglobin A1c level may be associated with acute kidney injury in patients undergoing coronary artery bypass grafting. This study will investigate the association of preoperative HbA1c levels with AKI after isolated coronary artery bypass grafting (CABG). Results Forty patients undergoing elective CABG were enrolled in this cohort study. Patients are divided into 2 equal groups who underwent isolated coronary artery bypass grafting (CABG): patients with preoperative HbA1c 5.7–6.4% (group A) (prediabetics) and patients with preoperative HbA1c > or = 6.5% (group B) (diabetics). Acute kidney injury according to the Kidney Disease: Improving Global Outcomes criteria developed in 11 patients (27.5%). There was a significant difference between the two groups as regards postoperative urinary NGAL, creatinine level on the 1st day, creatinine level on the 2nd day, urine output on the 1st day, and urine output on the 2nd day (p value was 0.001, 0.002, 0.006, 0.0002, and 0.012 respectively). Postoperative ICU stay duration was statistically significant in the diabetic group (P value 0.009). The need for renal replacement therapy was higher in the diabetic group, but it was not statistically significant between the two groups. Roc analysis shows AUC 0.922 with a significant p value (< 0.0001) and cut of value (≥ 7) with sensitivity 81.82 and specificity 93.10. Conclusion This study revealed that elevated preoperative HbA1c level above 7% showed an increase in incidence of post CABG acute kidney injury along with increase length of postoperative ICU stay.

Introduction: An effective postoperative pain management is of utmost importance following cardiac surgery. Various agents, routes and modes are available for the treatment of postoperative pain. Subcutaneous route of administration is an easy and effective method of postoperative analgesia with improved patient satisfaction and lesser side effects compared to intravenous route. Aim: To evaluate the efficacy of Subcutaneous Morphine (SCM) as postoperative analgesia following Coronary Artery Bypass Grafting (CABG). Materials and Methods: This study was designed as a retrospective analytical survey from June 2015 to June 2017. Medical records of all patients over 18 years of age who underwent coronary artery bypass grafting were reviewed. Patients belonging to ASA PS I, II and III, patients above 18 years of age and those posted for coronary artery bypass grafting were included in the study. Patients were divided into two groups: SCM group and Paracetamol (PCT) group, depending on the primary analgesia they received. The two groups were compared using Student’s t-test for normally distributed continuous data or non-parametric tests if the data were not normally distributed. Categorical data were compared by Fisher’s-exact test. The p-values <0.05 were considered statistically significant. Results: A total of 102 records were reviewed, out of which 49 patients received SCM and 53 patients had received PCT as their primary postoperative analgesia. It was observed that PCT group required more additional analgesia (intravenous fentanyl/ tramadol) than SCM group which was statistically significant with p-value of <0.001 and the duration of Cardiac Intensive Care Unit (CICU) stay was more in PCT group with p-value of 0.001. Postoperative side effects were significantly more in PCT group. Conclusion: SCM can be effectively administered intermittently for postoperative analgesia following CABG with similar haemodynamic stability and minimal side effects as compared to intermittent intravenous PCT.

Abstract Background Periprocedural myocardial injury after coronary artery bypass grafting (CABG) may affect the patient's prognosis and may be due to a different set of factors beyond the atherosclerotic plaque instability. Considering the challenges in the diagnosis of myocardial injury after CABG, the aim of this study was to determine the association between postoperative early elevation of high-sensitivity troponin T (hsTnT) and all-cause 30-day mortality after CABG. Methods We enrolled 600 consecutive patients who underwent CABG. The hsTnT value was measured immediately before surgery and in the morning of the first postoperative day. Results The baseline hsTnT was 13 ng/L (7–26 ng/L) and 273 patients (45.7%) had baseline hsTnT above the 99th percentile/upper reference limit (URL) (14 ng/L). The median for hsTnT at first postoperative day was 235 ng/L (152–425 ng/L). We calculated the postoperative hsTnT ratio to URL for each patient, representing the number of times exceeding the URL (hsTnT value divided by 14 ng/L). The multivariate analysis by Cox proportional hazard model revealed that age (years) (hazard ratio [HR] = 1.13, 95% confidence interval [CI]: 1.07–1.20; p < 0.001) and postoperative hsTnT ratio to URL (per 10-fold increase) (HR = 1.06, 95% CI: 1.04–1.08; p < 0.001) were independent predictors of all-cause 30-day mortality after CABG. Conclusion In our series, age and higher postoperative hsTnT levels were independent and reliable predictors of all-cause 30-day mortality after CABG.

Coronary artery disease (CAD) is one of the leading causes of morbimortality worldwide. In patients with diabetes mellitus type 2 (DM2), CAD is more likely to be a complex disease and often requires cardiac surgery. Furthermore, perioperative blood glucoselevels control is associated with the following outcomes: surgery success, mortality, and infection postoperative. This is a retrospective study, we have collected data form, 43 patients, between 2015 and 2017, with diabetes type 2 and who had passed through a Coronary Artery Bypass Grafting. Those with infection postoperative had a glycohemoglobin 7,9 (SD ±1,4), and those without infection had an HbA1c 7,25 (SD ±0,94) and a p-value from 0,039. Adding this was identified that the average of creatinine clearance in patients with the infectious disease was 59 (SD ±21,3) and 67(SD ±26)in those without infection, calculated a p-value from 0,039. High levels of Hb1Ac are a predictor of infection disease postoperative.

Objective: To compare early outcomes in antegrade conventional crystalloid cardioplegia with Del Nido (DN) cardioplegia in term of myocardial protection in patients undergoing CABG. Methodology: All the patients undergoing Coronary artery bypass grafting surgery were enrolled in this study after informed consent. Preoperative, intra-operative and postoperative variables were entered in the pre-designed proforma and patients were followed to compare early outcomes in Del-Nido versus Conventional Cardioplegia. Results: The mean age of the patients in Del Nido group was 54.61 ± 9.129 whereas the mean age of the patients in Conventional Cardioplegia group was 53.91 ± 10.39. There were 50(71.43%) males and 20(28.57%) females in Del-Nido group as compare with Conventional group 52(74.29%) males and 18(25.71%) females in this study. The mean cardioplegia volume given to Del Nido and Conventional Cardioplegia group as (1271.43 ± 447.91 vs 2142.86 ± 584.48 (ml/min) with p-value is <0.005 which shows there is a significant difference of Cardioplegia volume given to both groups. The mean cardiopulmonary bypass time (min) in Del Nido group was 116.87 ± 27.25 and in Conventional Cardioplegia group 106.58 ± 29.19 and the p-value of CPB time was significant 0.004. In our data 6(8.5%) patients from Del Nido Cardioplegia Group suffered from AKI whilst in Conventional Cardioplegia Group there were 7(10%) patients who suffered from AKI. Similarly 3(4.29%) patients from Del Nido Group and 2(2.86%) patients from conventional Cardioplegia Group previously suffered from stroke. Arrhythmia is a disorder of heart that affects the rate or rhythm at which the heart beats. Its p-value is significant (0.05) which shows there is a significant difference of this disorder in both groups Conclusion: There was a significant difference in post-operative complication Arrhythmia in both groups and the need for a lower cardioplegia volume and an uninterrupted procedure are the main advantages of Del Nido (DN) cardioplegia solution, which make it superior from conventional cardioplegia.

Long Term Follow Up

Study objective: To evaluate the long-term outcomes of clampless off-pump coronary artery bypass grafting (C-OPCAB) compared with conventional on-pump double clamping coronary artery bypass grafting (C-CABG). Methods: From October 2006 to December 2011, 366 patients underwent isolated coronary artery bypass grafting. After propensity score matching of preoperative variables, 143 pairs were selected who received C-OPCAB with the use of device-assisted PAS-Port proximal venous graft anastomoses or C-CABG, performed by the same surgeon experienced in both techniques. Data of the two groups of patients were retrospectively analyzed up to 14 years of follow-up. Results: As compared with C-OPCAB, in the C-CABG patients, the performed number of grafts per patient was higher (2.9 ± 0.5 vs. 2.6 ± 0.6, p-value 0.0001). At 14 years, overall survival, including in-hospital death, was 64 ± 4.7% for the C-OPCAB vs. 55 ± 5.5% for the C-CABG, freedom from overall MACCEs 51 ± 6.2% vs. 41 ± 7.7%, and from late cardiac death 94 ± 2.4% vs. 96 ± 2.2% (p-value not significant, for all comparisons). No significant statistical differences were observed in the actual rates of adverse events during follow-up. Independent predictors of survival were advanced age at operation (p-value 0.001) and a lower mean value of preoperative left ventricular ejection fraction (p-value 0.015). Conclusions: Our single-center study analysis suggests that clampless OPCAB using device-assisted proximal anastomoses proved to be not inferior to double-clamping CABG in the long-term follow-up, provided that involved surgeons are familiar with both techniques. These conclusions are supported by a large and long-term follow-up period, eliminating potential bias, i.e., by means of the propensity score matching and analyzing single-surgeon experience.
