The Impact

The aim of the study was to assess the impact of surgical revascularization on left ventricular function using standard echocardiographic study and Velocity Vector Imaging technology. Materials and methods. 40 patients with ischemic heart disease were examined before and 12 days, 6, 12 and 24 months after coronary artery bypass grafting (CABG). A standard echocardiographic (EchoCG) study was performed on ultrasound scanner Acuson Х 300 (Siemens, USA) with a 5–1 MHz sector multifrequency sensor. For objective assessment of myocardial function, the analysis of left ventricular (LV) deformation and rotational properties was performed using Syngo VVI (Siemens Medical Solutions USA Inc., США) in 720 LV segments. Results. Standard EchoCG showed a stable systolic, diastolic and contractile LV function during 2 years of follow-up. The study of global values of strain (S) and strain rate (SR) showed a decrease in longitudinal S 6 months after CABG in the right coronary artery (RCA) area in the group of patients with complaints compared to those who had no complaints (p = 0.004), in addition, in this zone there was a tendency to a difference in longitudinal SR between these two groups (p = 0.07). In anterior descending artery area was a tendency to decreased strain of longitudinal fibers (p = 0.06) during the same period of observation. 1 year after CABG, strain decreased in patients with complaints (p = 0.04) in the circumference artery area only in circular fibers. Positive dynamics were noted in the diastolic function of left ventricular fibers and rotation indices. Conclusion. The use of Velocity Vector Imaging after coronary bypass surgery shows a change in the function of myocardial fibers in the areas of coronary arteries, which is important in patients complaining of angina pain.

Aim. To study strain and strain rate dynamics the left ventricle (LV) myocardium fibers in patients with ischemic heart disease after coronary artery bypass grafting (CABG) in the early and late periods.Material and methods. The dynamics of strain (S) and strain rate (SR) of longitudinal, circular and radial fibers in 148 patients (in 2646 LV segments) before and on the 12th day after CABG was studied using Velocity Vector Imaging technology. In the long-term (6, 12 and 24 months) 40 patients (720 LV segments) were examined.Results. A positive dynamics of SR longitudinal fibers (p = 0.0002) was on the 12th day after CABG. Weak and medium correlation was between S and SR radial (R = –0.56; R = –0.52) and circular fibers with LDG-1 and duration of aortic clamping. In the long term, patients with complaints showed a decrease in global deformation properties in the coronary artery areas. The stable result of improvement S and SR longitudinal and circular fibers and SR radial fibers was obtained in segments with initially low deformation properties.Conclusions. The use of Velocity Vector Imaging technology allows to estimate the dynamics of LV fibers deformation parameters in early and long-term periods. In the early period after CABG was a positive dynamic only from the global SR longitudinal fibers. In the long-term global deformation parameters of longitudinal and circular fibers was decrease in in the area of the coronary arteries. In the long-term was a significant improvement of the deformation parameters of segments with initially low deformation properties.

Objective: In this review, we assess the outcome of surgical revascularization technique, coronary artery bypass grafting (CABG) with or without coronary endarterectomy (CE) for patients with diffuse coronary artery disease in a single surgeon’s practice.Methods: We retrospectively reviewed 2189 patients who experienced OPCABG with or without CE between January 2009 and December 2016. The following variables were compared in this study- Intubation time, ICU stay, Postoperative MI, Arrhythmia, renal impairment, stroke and ICU mortality.Results: Of 2189 patients, 1000 patients required coronary endarterectomy in addition to OPCABG. Initially, there was a higher mortality rate and incidence of postoperative blood transfusion in the group of patients who had CE in addition to CABG, with no significant difference in other outcomes. But postoperative use of Heparin, Warfarin and Double antiplatelet agent was associated with decreased mortality significantly in our study. In comparison to other group, the patients in the combined CE with CABG group had a higher incidence of male sex, past MI, and poor left ventricular function. However,emergency CABG, renal impairment, poor left ventricular function, and also peripheral vascular disease were associated with higher mortality in both group of the patients; CE was not a predictor of postoperative mortality.Conclusions: Total surgical revascularization is attainable and accomplishes, when Coronary endarterectomy is performed in addition to Off-pump coronary artery bypass graft in patients when there is no other choice for satisfactory revascularization.Bangladesh Heart Journal 2017; 32(2) : 77-84

Global Work

Abstract Background Coronary-artery bypass grafting (CABG) without the use of cardio-pulmonary bypass (CPB) was introduced to avoid the potential damaging effects of fpreign surfaces. Nevertheless, the value of off-pump CABG (OPCAB) remains controversial. Regional myocardial work has been shown to reflect regional metabolic demand and provide a more comprehensive assessment of myocardial function. Recently a novel non-invasive method for assessing regional MW by LV pressure–strain loop analysis has been described. Purpose To detect changes of MW after CABG comparing off- and on-pump techniques. Methods We prospectively evaluated 93 patients undergoing CABG (50 on- vs. 43 off-pump). Patients underwent transthoracic echocardiography exams prior to and one week after surgery as well as concurrently systolic arterial blood pressure measurements at rest. Besides conventional echocardiography parameters, wemeasured global longitudinal strain (GLS), global work index (GWI) and global work efficiency (GWE). Results All patients survived surgery. Patients in the OPCAB group had significantly higher EuroSCORE II (3.3% vs. 1.1%, p < 0.001). Preoperatively, OPCABgroup had significantly lower EF (50.1 vs. 55.7%, p = 0.004), lower GWI (1411 vs. 1650mmHg%, p = 0.039) and lower GWE (86.7 vs. 91.6%, p = 0.017). GLS did not differ significantly between off- and on-pump groupspreoperatively. However, postoperatively GLS, MWI, MWE and EF decreased significantly within the on-pump group (p < 0.001, p < 0.001, p < 0.001 and p = 0.002, respectively). In the OPCAB group only GWI and GLSdecreased significantly (p = 0.028 and p = 0.017, respectively). Due to the fact, that mean differences between all pre- and postoperative values were higher in the on-pump group, no significant differences in systolic LV-function (sLVF) could be detected between on- and off-pump patients postoperatively. During the early postoperative phase, no correlation between GWI and GWE and clinical outcomes could be detected, onlylower preoperative-GWI values showed a weak correlation with the incidence of postoperative cardiogenic shock (r= -0.27, p = 0.029). Conclusion Despite having worse preoperative sLVF in the off-pump group determined by EF, GLS, GWI and GWE, the decrease in sLVF parameters was significantly higher in the on-pump group, leading to an equal distribution of LV-function parameters between off- and on-pump patients postoperatively. Our results suggest that off-pump CABG provides a better preservation of LV-function.

Significant Superiority

Coronary artery bypass graft (CABG) surgery is one of the treatment modalities of coronary artery disease (CAD) patients. There are multiple selection criteria for CABG and multiple procedures like conventional CABG, on pump beating heart CABG and off pump beating heart CABG (OPCAB). This study was intended to compare between conventional CABG and on pump beating heart CABG. Total 60 patients were selected for the study, of which 30 patients had undergone conventional CABG and 30 had undergone on pump beating heart CABG. Different preoperative and postoperative variables shows clear and significant superiority of on pump beating heart CABG. So it may be an alternative surgical procedure where OPCAB is not feasible in poor left ventricular (LV) .function. Journal of Surgical Sciences (2014) Vol. 18 (1) : 20-27

Soluble St2

Background and Objectives: The aim of this study was to investigate the prognostic value of soluble ST2 (sST2) in predicting postoperative adverse events in patients with impaired left ventricular (LV) function undergoing coronary artery bypass graft (CABG) surgery. Materials and Methods: This study included 80 consecutive patients with stable coronary artery disease (CAD) and impaired LV function (ejection fraction ≤ 45%) undergoing on-pump coronary artery bypass graft surgery. The patients were divided into the “high” or “low” group according to their ST2 levels (≥35 or <35 ng/mL). Results: Postoperative adverse events were more common in patients with high sST2 levels than in patients with low sST2 levels (100% vs 26%, p < 0.0001). Multivariate analysis showed that sST2 level was an independent predictor of the presence of postoperative adverse events (OR: 1.117 (95% CI: 1.016–1.228), p = 0.022). The receiver operating characteristic curve (ROC) analysis of sST2 revealed an area under the curve (AUC) of 0.812 (95% CI: 0.710–0.913, p < 0.001) in predicting postoperative adverse events. An sST2 level of 26.50 ng/ml was identified as the optimal cut-off value, with a sensitivity and specificity of 74.1% and 75.3%, respectively. Conclusion: Higher sST2 levels were associated with adverse outcomes after CABG in patients with impaired LV and stable CAD.

The purpose of the study was to assess the function of fibres of the left ventricle (LV) and its dynamics after revascularization in patients with non Q myocardial infarction using standard Echocardiography (EchoCG) and Velocity Vector Imaging (VVI). Materials and methods: 34 patients with MI were examined. Echocardiography studies were performed on the ultrasound scanner AcusonX 300 (Siemens), a 1–5 MHz transducer before and in early period after coronary artery bypass grafting (CABG). Results. Standard EchoCG showed systolic LV dysfunction before and after CABG, contractile dysfunction in 51 (8%) segment before the operation, with subsequent recovery of the function of the 28 (54%) of them. The effect of MI on LV function using VVI showed reducing strain (S) and normal strain rate (SR) of the longitudinal fibers, decrease S and SR of circular fibers and normal function of radial fibers. After GABG S and SR of longitudinal fibers has not changed, S and SR of the circular fibres are decreased. The function of radial fibers are normal. The study established a relationship between the level of LDH-1 and SR of the circular fibers of the LV prior to CABG. Increased level of LDH-1 in the early period after CABG can be a predictor of reduction of S and SR circular fibers. Conclusion: In patients with it is necessary to analyze not only the longitudinal and radial fibers, but also circular.
