“…22,32,33 Later studies by Ergunes K, Topkara VK et al had shown that postoperative stroke were more common among patients with low ejection fraction rather than type of conduit used. 29,31 We observed no mortality in either groups till the follow up of 3 months. Studies have shown that there was no difference in hospital mortality in LIMA and non LIMA group as Topkara VK et al concluded that in-hospital mortality was not dependent on type of conduit used rather it depends on the preoperative ejection fraction.…”

“…We found that incidence of acute renal failure was more in diabetics that were insulin dependent, requiring more that 30 units per day and with low ejection fraction. [29][30][31] Though no incidence of post-operative CVA was reported in our study. Incidence of post-operative CVA ranges from 0.9% to 2.4% in LIMA group and 0.9% to 1.9% in venous group with statistically significant difference.…”

A comparison of left ventricular function in patients undergoing beating heart bypass surgery using mixed versus pure venous conduits

Background: The pathophysiology of coronary artery disease was established in 1876 by Adam Hammer when he postulated that angina is caused by interruption of coronary blood supply and that myocardial infarction occurred after the occlusion of at least one coronary artery. Aims of the study were to compare the left ventricular function in patients who have undergone beating heart bypass surgery using mixed (internal mammary artery and venous conduits) versus pure Venous conduits, and to compare the incidence of postoperative complications.Methods: It was an observational, analytical study. All patients admitted with triple vessel disease requiring CABG (n=50), with ejection fraction >30%, were subjected to either left internal mammary artery and venous conduits (group A, n=25) or only venous conduits (group B, n=25). Patient who had undergone prior surgical myocardial revascularization, preexisting valvular disease, any evidence of raised pulmonary arterial pressure more than 40/15 mmHg, operated using cardiopulmonary bypass machine, pre-operative use of Intra-Aortic Balloon Pump, any history of neurological dysfunction/Transient ischemic attack, left atrium size more than 5.5 cm were excluded from the studyResults: Improvement in left ventricular function after coronary artery bypass grafting was objectively demonstrated in both the groups. There was a statistically significant increase in mean LVEF in group B (56.16±4.13) compared to group A (51.96±5.30) at 3 months of follow up (p=0.009). The most common complication in both the groups were atrial fibrillation group A=36% (n=9), group= B 16 % (n=4), renal failure group A=12% and group B=8% and sternal wound infection. The post-operative bleeding (Drain output) in first 24 hours was similar in both the groups, 295.56 ml in group A and 265.20ml in group B (p=) with similar hospital stay (group A=9days, group B=8.5days).Conclusions: Patients with venous conduits have better postoperative LVEF as compared to Mixed conduit with similar rate of post-operative complications.

“…Generally, the mortality rate in patients with severe left ventricular dysfunction after the coronary artery bypass surgery is 2.7%-33% but there are many effective factors influencing the result of the surgery, including female gender, weak function of the left ventricular, diabetes, emergency surgery, arterial involvement, and ejection fraction (EF), which is assessed by Echocardiography (6,7). According to the available information, it is considered an EF of below 30% shows weak function of left ventricular (8). This is why some researchers described the coronary artery bypass surgery in these patients with high mortality risk after the operation.…”

A survival after coronary artery bypass grafting surgery with ejection fraction below 30 percent

2018

Introduction: Regarding the progress in surgeries, the mortality rate of coronary artery bypass grafting surgery is still low, despite advanced age and comorbidities. One of the independent causes of mortality rate is low ejection fraction (EF). This study aimed to assess mortality after coronary artery bypass grafting (CABG) operation in patients with ejection fraction under 30%. In the present study the experience of 20 patients with an EFbelow 30% and 20 patients with an EF above 30% was investigated in Birjand in which only three of the patients died within 2 years after the operation. Methods: This crross-sectional descriptive study was conducted on 40 patients in Birjand Vali-e-aser Hospital. Out of the 40 cases, 20 patients had EF below 30% and 20 subjects had EF above 30 %. The files of all the cases undergoing heart surgery with an EF were obtained since 2015 to 2017, and then their demographic features, such as addresses and phone numbers were collected. Afterwards, they were called and their mortality was checked and the data were analyzed with independent-samples t-test. In addition, the ratios were examined in SPSS Software (version 22) and P-value considered higher than 0.05. Results: From 2015 to 2017, the two groups, including 20 patients with EF<30% and 20 patients with EF>30%, undergone CABG surgery in Birjand University of Medical Science, 65% of which were men and 35 % were women with the age range of 64.7 for the cases with EF<30 and 62.5 for the subjects EF>30. One of the patients died with an EF above 30% and two subjects died with EF below 30%. Conclusions: The mortality rate can be reduced with providing appropriate care despite the fact that an EF<30% is an independent cause of mortality and according to the results of the present study which showed three patients died after the CABG operation.
