RESUMO
BACKGROUND The Glasgow prognostic score (GPS) consists of a combination of serum C-reactive protein and albumin levels as indicators of systematic inflammatory response and nutritional status, respectively. The present retrospective study aimed to evaluate the association between the GPS and atrial fibrillation, stroke, and mortality at 30 days and 1 year after coronary artery bypass graft (CABG) surgery. MATERIAL AND METHODS Patients with chronic coronary syndromes who underwent CABG surgery between 2012 and 2019 in a single center were included. Preoperative GPS was calculated. Then, patients were grouped according to postoperative atrial fibrillation (POAF) development. Further, groups were formed to evaluate the relationship between GPS and 30-day and 1-year cardiovascular mortality as well as stroke development. RESULTS Patients who developed POAF had higher GPS, higher European System for Cardiac Operative Risk Evaluation (EuroSCORE II) score, advanced age, lower angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) use, lower left ventricular ejection fraction, and were more likely to be female and to have a history of carotid artery disease (P<0.05, for all). Additionally, GPS, EuroSCORE II, advanced age, and lower left ventricular ejection fraction were detected as independent risk factors for POAF development. When adverse outcomes were assessed, cardiovascular mortality at 30 days or 1 year, and stroke development at 1 year, were more frequent in patients with POAF. Moreover, POAF development was found to be an independent risk factor for adverse outcomes. Also, GPS was established as an independent risk factor both for 30-day and 1-year cardiovascular mortality (P<0.0001 and P=0.001, respectively). CONCLUSIONS GPS is an easy-to-calculate score that has reasonable diagnostic accuracy in determining the risk of POAF and stroke as well as 30-day and 1-year cardiovascular mortality.

OBJECTIVES: The main focus of this study is to evaluate the reliability and durability of saphenous vein bypass grafting from common carotid artery to internal carotid artery (CBG) asan alternative treatment of patients with carotid artery stenosis. METHODS: 459 patients with carotid artery stenosis underwent initial carotid endarterectomy (CEA) or CBG between 2009 and 2019. Propensity score matching was performed, and outcomes of two different surgical procedures were analyzed. RESULTS: Outcomes of the 142 pairs of matched patients were investigated. There were no significant differences in the preoperative characteristics of these matched groups. Overall mean time of follow-up was 91.364 ± 3.265 months. Mortality rate during the follow-up period was 18.309% (26 patients) in the CEA group, and 11.971% (17 patients) in the CBG group. Stroke was encountered in 8 patients in the CEA group (5.63%), and 3 patients in the CBG group (2.11%) during follow-up. Restenosis was detected in 11 patients in the CEA group (7.75%), and 3 patients in the CBG group (3.52%) during follow-up. There were no significant differences in the survival, stroke - free survival, and restenosis - free survival distributions of both groups. CONCLUSIONS: In carotid artery stenosis, it is reasonable to consider CBG as an alternative surgical option when adequate disease-free inflow (common carotid artery) and outflow (distal internal carotid artery) segments are present.

Cardiac involvement in hydatid cyst disease is a rare manifestation and may remain asymptomatic for years. The location of the cyst determines the presentation. In this report, we present a case of hydatid cyst presenting with massive pericardial effusion, right ventricle compression leading to cardiac tamponade. The diagnosis was established with transthoracic, transesophageal echocardiagraphy and computed tomography.

Chest tubes are commonly used for patients who have undergone a cardiothoracic procedure to avoid the complications related to the accumulation of blood and serous fluid in the chest. Although the traditional methods such as milking, stripping or active chest tube clearance devices are used to establish patency of the chest tubes, they can become clogged at any time after their placement. Our technique may re-establish the tube patency with utilising Fogarty catheter and without any detriment to tissues.

BACKGROUND: Intracardiac malignancies are extremely rare and hard to detect or differentiate preoperatively. CASE REPORT: We present a 48-year-old female patient who was diagnosed primarily with left atrial myxoma and taken into emergency surgery. The tumor extended into the pulmonary veins and infiltrated the atrial endocardium, and the histopathologic diagnosis was leiomyosarcoma. The left atrial endocardium was successfully peeled off with the tumor and complete resection was achieved. CONCLUSION: The possible malignant nature of intracardiac masses should be kept in mind, especially in middle-aged patients. The extent of the tumor must be determined in elective cases to establish the proper strategy for complete resection, which is the only chance of successful treatment for this lethal disease entity. Endocardial peeling is warranted for successful removal of the tumor mass in leiomyosarcoma.

INTRODUCTION: The aim of this study was to evaluate the efficacy and safety of innominate artery cannulation strategy with side-graft technique in proximal aortic pathologies. METHODS: A total of 70 patients underwent innominate artery cannulation with a side graft for surgery on the proximal aorta from 2012 to 2020. There were 46 men and 24 women with an average age of 56±13 years. The indications for surgery were type A aortic dissection in 17 patients (24.3%), aortic aneurysm in 52 patients (74.3%), and ascending aorta pseudoaneurysm in one patient (1.4%). The innominate artery was free of disease in all patients. Hypothermic circulatory arrest with antegrade cerebral perfusion was utilized in 60 patients (85.7%). Three patients had previous sternotomy (4.2%). The most common surgical procedure was ascending aorta with hemiarch replacement in 34 patients (48.5%). RESULTS: The mean cardiac ischemia and cardiopulmonary bypass times were 116+46 minutes and 164+56 minutes, respectively. Mean antegrade cerebral perfusion time was 27+14 minutes. The patients were cooled between 22°C and 30°C during surgery. Thirty-day mortality rate was 7.1% (five patients). One patient (1.4%) had stroke, one patient (1.4%) had temporary neurologic deficit, and eight patients (11.4%) had confusion and agitation that resolved completely in all cases. There was no local complication or arterial injury. CONCLUSION: Cannulation of the innominate artery with side graft is safe and effective for both cardiopulmonary bypass and antegrade cerebral perfusion. This technique provides satisfactory neurologic outcomes for proximal aortic surgery.

INTRODUCTION: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II and the Society of Thoracic Surgeons (STS) are validated scoring systems for short-term risk estimation after coronary artery bypass grafting (CABG). The Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score is originally aimed to estimate mortality in heart failure patients; however, it has showed a similar power to predict mortality after heart valve surgery. In this study, we sought to evaluate whether MAGGIC score may predict short and long-term mortality after CABG and to compare its power with EuroSCORE II and STS scoring systems. METHODS: Patients who underwent CABG due to chronic coronary syndrome at our institution were included in this retrospective study. Follow-up data were used to define the predictive ability of MAGGIC and to compare it with STS and EuroSCORE-II for early, one-year, and up to 10-year mortality. RESULTS: MAGGIC, STS, and EuroSCORE-II scores had good prognostic power, moreover MAGGIC was better for predicting 30-day (area under the curve [AUC]: 0.903; 95% confidence interval [CI]: 0.871-0.935), one-year (AUC: 0.931; 95% CI: 0.907-0.955), and 10-year (AUC: 0.923; 95% CI: 0.893-0.954) mortality. MAGGIC was found to be an independent predictor to sustain statistically significant association with mortality in follow-up. CONCLUSION: MAGGIC scoring system had a good predictive accuracy for early and long-term mortality in patients undergoing CABG when compared to EuroSCORE-II and STS scores. It requires limited variables for calculation and still yields better prognostic power in determining 30-day, one-year, and up to 10-year mortality.

RESUMO
BACKGROUND: Correlation of increased copeptin levels with various cardiovascular diseases has been described. The clinical use of copeptin levels in patients with hypertrophic cardiomyopathy (HCM) has not been investigated before. HYPOTHESIS: In this study, we aimed to investigate the prognostic value of copeptin levels in patients with hypertrophic cardiomyopathy (HCM). METHODS: HCM was defined as presence of left ventricular wall thickness ≥15 mm in a subject without any concomitant disease that may cause left ventricular hypertrophy. Levels of copeptin and plasma N-terminal probrain natriuretic peptide (NT-proBNP) were evaluated prospectively in 24 obstructive HCM patients, 36 nonobstructive HCM patients, and 36 age- and sex-matched control subjects. Blood samples were collected in the morning between 7 and 9 am after overnight fasting. Patients were followed for 24 months. Hospitalization with diagnosis of heart failure/arrhythmia, implantable cardioverter-defibrillator implantation, and cardiac mortality were accepted as adverse cardiac events. RESULTS: Copeptin and NT-proBNP levels were higher in the HCM group compared with controls (14.1 vs 8.4 pmol/L, P < 0.01; and 383 vs 44 pg/mL, P < 0.01, respectively). Copeptin and NT-proBNP levels were higher in the obstructive HCM subgroup compared with the nonobstructive HCM subgroup (18.3 vs 13.1 pmol/L, P < 0.01; and 717 vs 223 pg/mL, P < 0.01, respectively). In multivariable logistic regression analysis, copeptin and NT-proBNP levels remained as independent predictors of heart failure (P < 0.01 for both) and adverse cardiac events (P < 0.01 for both). CONCLUSIONS: Copeptin and NT-proBNP levels were significantly higher in patients with obstructive HCM, and higher levels were associated with worse outcome.

In situ right internal mammary artery is the graft of choice in reoperative off-pump coronary artery bypass grafting, as well as in primary on-pump coronary artery bypass grafting, unless the vessel has been used previously. However, there are not enough data about postoperative angiographic findings of the in situ right internal mammary artery in reoperative coronary artery bypass grafting with the off-pump technique. From September 1993 through January 2004, we reviewed the postoperative course and the graft patency of 12 selected patients who underwent off-pump coronary artery bypass grafting reoperation only for revascularization of the left anterior descending artery, by means of a pedicled right internal mammary artery graft. All patients were evaluated clinically and by postoperative coronary angiography. There were no early or late deaths during the mean follow-up period of 33.08 +/- 30.05 months (range, 1-77 months). The mean interval from the 1st operation to the 2nd operation was 74.1 +/- 57.01 months (range, 4.5-171 months). Postoperative coronary angiograms of all patients showed a 100% patency rate for both in situ grafts and composite grafts. We suggest that use of the in situ right internal mammary artery in off-pump coronary artery bypass grafting is a safe and reliable option for revascularizing the left anterior descending artery, especially in reoperation.

OBJECTIVES: Acute kidney injury can occur after cardiac catheterization and cardiac surgery. The negative effects of the contrast media and cardiopulmonary bypass on renal function may be additive when performed in close succession. The results in the literature are, however, conflicting. METHODS: Preoperative, operative, perioperative and postoperative variables of 573 consecutive adult patients who underwent cardiac surgery on cardiopulmonary bypass were collected prospectively. Acute kidney injury (AKI) was defined according to the Acute Kidney Injury Network criteria based on changes in serum creatinine level within 48 h of surgery. RESULTS: Acute kidney injury was detected in 233 patients (41%). In a multivariate analysis, older age (P = 0.01), longer cardiopulmonary bypass time (P = 0.003), lower preoperative haematocrit level (P = 0.02) and higher body mass index (P = 0.001) were found to be independently associated with development of acute kidney injury. Analysis of the time from cardiac catheterization to surgery by logistic regression modelling did not show any significant change in the risk of acute kidney injury. Risk related to time from catheterization to surgery was not increased even in the patients with elevated preprocedural creatinine levels (>106 µmol l(-1); P = 0.23), left ventricular dysfunction (ejection fraction <40%; P = 0.19) and older age (≥70 years; P = 0.86). CONCLUSIONS: The time from cardiac catheterization to cardiac surgery is not a risk factor for the development of postoperative acute kidney injury even in patients with other risk factors. Surgical intervention should not be delayed in emergency or urgent cases. The optimization of renal function seems to be the correct strategy in clinically stable patients with risk factors for acute kidney injury.

OBJECTIVES: Atrial fibrillation (AF) after cardiac surgery has been reported to be approximately 30%, making it one of the most important causes of morbidity and mortality post surgery. Although various clinical and laboratory predictors and underlying mechanisms progressing to postoperative AF have been proposed, the role of ischaemia in pathogenesis is doubtful. In this study, the association of coronary collateral circulation (CCC) and severity of coronary artery disease (CAD) with the development of postoperative AF was investigated. METHODS: A total of 597 patients who underwent on-pump coronary artery bypass surgery were included in the study. Pre-, peri- and postoperative variables were recorded in a computerized database. CCC and severity of CAD were documented for each patient according to Rentrop classification and Gensini score. RESULTS: Postoperative AF was observed in 96 patients (16.1%). Advanced age, female gender, presence of hypertension and low haematocrit level were significantly associated with postoperative AF. By contrast, CCC and severity of CAD were not associated with postoperative AF (P = 0.22 and 0.5, respectively). Older age and lower preoperative haematocrit levels were the major predictors of postoperative AF development in the multivariate regression analysis. CONCLUSIONS: CCC and severity of CAD did not have a significant effect on the occurrence of postoperative AF, suggesting an ineffective role of myocardial ischaemia in the development of this condition.

AIM: Late occlusion of bypass grafts is one of the main issues associated with long-term survival after coronary artery bypass grafting (CABG) surgery. Left coronary system is generally revascularized using arterial conduits, whereas saphenous venous grafts are used for right coronary system. We investigated the prognostic factors that are related to the patency and risk of occlusion of saphenous venous grafts used for revascularization of diseased right coronary arteries. PATIENTS AND METHOD: 92 patients who underwent CABG operation including a right coronary artery (RCA) bypass using saphenous venous graft (SVG) between January 2003 and July 2010 were evaluated retrospectively. Mean time of follow up was 66.9 ± 27.2 months (range 104-13 months). Grafts patencies were investigated using coronary angiography, and associated risk factors for mortality and morbidity were determined during the mid-term and long-term follow up. During the data collection phase, a significant association was noticed between patency of right coronary bypass grafts and site of distal anastomoses on RCA. Thus, patients were divided into two groups, according to the site of anastomosis. Right coronary anastomoses were performed either proximal (Group A, n = 44) or distal (Group B, n = 46) to the crux of the RCA (PDA). RESULTS: Patency rates were similar in-group A (50% occluded and 50% patent) whereas patency rates were significantly higher in-group B (occluded 16.7%, patent 83.3%, p = 0.001). Mean age was significantly higher in-group A compared to Group B (p <0.05); however, there was no statistically significant difference between the two groups with regard to risk factors associated with cardiovascular disease (p >0.05). Also, mean diameter of the target vessel was significantly higher in-group A (p <0.01). CONCLUSION: Based on the results of our study we suggest that even though an appropriate segment for anastomosis is available proximal to the crux of the RCA, right posterior descending artery (PDA) should be preferred for revascularization when RCA is the target vessel in CABG.

BACKGROUND: Behcet's disease is a chronic inflammatory disease with a relapsing course. Behcet's disease affects many systems and causes hypercoagulability, and detection of an intracardiac mass in a Behcet patient should raise the question of an intracardiac thrombus. We analyzed our patients with Behcet's disease operated for valvular disease. METHODS: We operated three patients (one male and two females) who had been diagnosed as having Behcet's disease previously. Using mechanical bileaflet valves, aortic valve replacement in two and mitral valve replacement in the other patient were performed. Mechanical valve replacement was performed using pledgetted-interrupted sutures in the mitral procedure. Patients' steroid therapies were not interrupted and in the postoperative course, steroid was continued. No reoperations were needed. Anticoagulation with warfarin was instituted after the operation with the target of an international normalized ratio (INR) between 3 and 3.5. RESULTS: There was no mortality either early or late follow-up. Intraoperative and postoperative courses were uneventful. Two had ventricular arrhythmias. Total follow-up was 23.3 patient/years with a mean of 93.3 +/- 64.7 months. In the late follow-up, patient with the mechanical mitral valve experienced a cerebrovascular accident 40 months after the operation. Her echocardiographic examination gave a functional valve without any pathology. CONCLUSIONS: Surgeons should remember the hypercoagulable state in Behcet patients and strict anticoagulation protocols should be utilized. In the operations, bileaflet prostheses should be used.

OBJECTIVE: Internal thoracic artery (ITA) grafting to the left anterior descending artery (LAD) may have catastrophic consequences and can be fatal due to "ITA malperfusion syndrome." We have investigated the efficacy of a second graft in this syndrome. METHODS: A total of 35 patients, 29 males (82.9%) and 6 females (17.1%), with a mean age of 53.0 +/- 8.7, (range: 38 to 70) undergoing coronary artery bypass grafting required a second supply to LAD due to ITA malperfusion syndrome. This was performed using a saphenous vein graft. The mean number of distal anastomosis was 2.7 +/- 0.45 per patient (range: 1 to 5). The decision for an additional grafting procedure was made in the first operation for 18 patients (51.4%) (Group I). For the remaining 17 patients (48.6%) (Group II), the additional grafting procedures were performed during a reoperation after the development of ischemic complications in the intensive care unit (ICU). RESULTS: The early mortality rate was 8.6% (3 of 35). Two patients had perioperative myocardial infarction (MI) (5.7%). The second vein graft proved to dramatically reduce the incidence of postoperative MI. Malignant refractory arrhythmias were recorded in 17 patients (48.6%). Twelve patients (34.3%) required inotropic support and seven patients (20%), all in Group II, required intra-aortic balloon pump (IABP) support. The average duration of IABP was 5 days +/- 1.8 days (range: 3 to 7). The necessity of IABP support was found to be statistically higher in the second group compared to the first one. CONCLUSIONS: Double supply to LAD using an additional saphenous vein graft is the treatment of choice for ITA malperfusion syndrome. The time interval between the first and the second grafts appears to be crucial for postoperative patient outcome.
