RESUMEN
Background: In this study, we aimed to evaluate primary outcomes and main characteristics of emergency and elective/urgent cardiovascular surgeries which were performed in the first three months of the novel coronavirus disease 2019 (COVID-19) pandemic in our center. Methods: Between March 11th, 2020 and June 11th, 2020, a total of 209 patients (44 males, 165 females; mean age: 57.3±12.8 years; range, 20 to 80 years) who underwent emergency or elective/urgent surgery with cardiovascular pathologies were retrospectively analyzed. The patients were classified as emergency and elective/urgent according to the level of necessity of the surgical procedure at the time of hospital admission. Pre-, intra-, and postoperative data of the patients were recorded. Results: During the study period, 156 elective/urgent and 74 emergency cardiovascular surgeries were performed. Six COVID-19 (+) patients were operated emergently. The number of acute aortic dissection and peripheral vascular surgery was higher in the emergency group (p<0.05). Two patients who were COVID-19 (-) preoperatively became COVID-19 (+) in the postoperative period. In these patients, acute respiratory distress syndrome developed, and extracorporeal membrane oxygenation support was needed. Four patients who needed post-cardiotomy extracorporeal membrane oxygenation support due to low cardiac output were COVID-19 (-) both in the pre- and postoperative periods. The overall in-hospital mortality rate was 9.1%. Conclusion: Even during pandemic such as COVID-19, referral centers with experienced personnel can provide non-pandemic healthcare with a quality close to the daily routine.
RESUMEN
A 65-year-male patient was admitted to our clinic with swollen, painful, and wound discharge of lower extremity. There was widespread edema, skin infection, and lymphangitis secondary Stage 3 lymphedema below the knee. In addition to conventional treatment methods, lymphatic artificial pathway creation was used with subcutaneous implantation of silicone tubing. In conclusion, subcutaneous implantation of silicone tubing is a new technique that can be applied in advanced stage lymphedema patients, which increases the effectiveness of compression therapy.
RESUMEN
Background: This study aims to investigate the association of progression of tricuspid regurgitation following double-valve replacement by comparing the tricuspid valve repair and no repair groups, and to analyze outcomes of patients with non-repaired mild-to-moderate tricuspid regurgitation. Methods: Between January 2014 and September 2017, a total of 157 patients (74 males, 83 females; mean age: 51.7±13.7 years; range, 18 to 78 years) who underwent aortic and mitral valve replacements with/without concomitant tricuspid valve repair were retrospectively analyzed. The patients were divided into two groups: no-repair (n=78) and repair groups (n=79). The primary outcome measure was development of more than moderate tricuspid regurgitation during follow-up. Results: The data were evaluated according to propensity score matched analysis. The progression of tricuspid regurgitation was significantly increased in the no-repair group (p=0.006). Rheumatic etiology was independently associated with the presence of postoperative moderateto- severe tricuspid regurgitation (p=0.004, odds ratio: 3.40). There was no statistically significant difference between the groups in terms of the potential complications and mortality and survival rates. A multivariable subgroup analysis for the baseline mild-to-moderate tricuspid regurgitation without repair showed that rheumatic etiology was an independent factor for the progression of postoperative tricuspid regurgitation (p=0.01). Conclusion: Our study results demonstrated that rheumatic etiology was an independent marker for increased tricuspid regurgitation and it was also independently associated with increased tricuspid regurgitation in patients with mild-to-moderate non-repaired patients. The degree of tricuspid regurgitation was improved in the repair group during follow-up.
RESUMEN
Abstract Introduction: In this trial, we initially aimed to investigate the major predictive factors for prolonged mechanical ventilation (PMV) following cardiac surgery with cardiopulmonary bypass (CPB) in our center and, secondarily, we tried to find out the effects of the independent factors on mortality. Methods: Between July 2017 and August 2018, 207 patients who underwent cardiac surgery with CPB were retrospectively investigated. The patients were randomly divided into two subgroups according to the duration of ventilator dependence (group 1 <24 hours, n=164, 79%; group 2 >24 hours, n=43, 21%). Results: 207 patients (mean age 59.47±10.56) who underwent cardiac surgery with CPB were enrolled in this study (n=145, 70% of male patients; n=62, 30% of female patients). Amid these patients, 43 (n=43, 20.77%) had prolonged intubation time. After multivariate logistic regression analysis among preoperative factors, female gender (OR=2.321, P=0.028), leukocytosis (OR=1.233, P=0.006), perioperative lactate level (OR=1.224, P=0.027), CPB time (OR=1.012, P=0.012) and postoperative revision for bleeding (OR=23.125, P=0.040) were significantly detected. The effect of predictive factors on mortality after cardiac surgery was determined and found that PMV did not affect hospital mortality (OR=1.979, P=0.420). Conclusion: In our report, we revealed, differently from previous studies, that intraoperative lactate levels which manifest organ perfusion and oxygenation were included and were significantly different in the early extubation group compared to the PMV group. Female gender, preoperative leukocytosis, intraoperative CPB time, lactate levels and postoperative revision for bleeding were the independent predictive factors for PMV. Moreover, PMV did not affect the early-term mortality during hospital stay.

OBJECTIVE: To evaluate the clinical impact of coronary dominance type in terms of early and long-term outcomes in patients undergoing elective coronary artery bypass grafting (CABG). METHODS: A total of 844 consecutive patients who underwent elective CABG were divided into two groups based on preoperative angiographic views as left dominant (LD) and right dominant or co-dominant (RD+CD). The measured outcomes were postoperative complications, 30-day mortality, long-term mortality, and major adverse cardiac and cerebrovascular events (MACCE). RESULTS: RD+CD was present in 87.9% (n=742) and LD in 12.1% (n=102) of patients. Postoperative complications, 30-day mortality, and 30-day readmissions were similar in both groups. The median duration of follow-up was 3.4 years. LD was not an independent predictor of mortality (adjusted hazard ratio [HR] 1.53, 95% confidence interval [CI] 0.89-2.45, P=0.12), but it was an independent predictor of MACCE in the long term (adjusted HR 2.18, 95% CI 1.39-3.42, P=0.001). CONCLUSION: In patients undergoing elective surgical revascularization, left coronary dominance is associated with increased MACCE risk in the long term. Therefore, the assessment of coronary dominance type should be an integral part of outpatient management after CABG.

OBJECTIVE: This study aims to compare the efficacy of enoxaparin, rivoraxaban and dabigatran on wound healing using a rat model. METHOD: Sprague-Dawley female rats (n=56), 10-12 weeks old, weight 245±30g, were used in this study. The rats were divided into four equally-sized groups. A type 1 (secondary wound healing) and type 2 (primary wound healing) wound was opened surgically on each rat in each group. Anticoagulent drugs enoxaparin, rivoraxaban and dabigatran and physiological saline solution were administered to Groups 1, 2, 3 and 4, respectively. After wound healing was scored tissue samples were taken from euthanised rats at days five and 10 and examined histologically. Since time was used as a classification (days five and 10), a time effect was included. RESULTS: There was no statistically significant difference in total score distribution in rats between type 1 secondary wounds for days five and 10 (p>0.05). There was no statistically significant difference in the overall score distribution in rats between type 2 primary wounds for days five and 10 (p>0.05). CONCLUSION: In addition to the use of low molecular weight heparin with well-known anticoagulation activity, the new generation oral medications are used efficiently in thromboembolic diseases. However, there was no evidence observed in this study that these drugs could be either beneficial or harmful to wound healing.

RESUMEN
Abstract Objective: Acute kidney injury (AKI) is one of the most important complications after coronary artery bypass grafting (CABG) procedure. Serum albumin, which is an acute phase reactant, is suggested to be associated with AKI development subsequent to various surgical procedures. In this study, we research the relation between preoperative serum albumin levels and postoperative AKI development in diabetes mellitus (DM) patients undergoing isolated CABG. Methods: We included a total of 634 diabetic patients undergoing CABG (60.5±9.1 years, 65.1% male) into this study, which was performed between September 2009 and January 2014 in a single center. The relation between preoperative serum albumin levels and postoperative AKI development was observed. AKI was evaluated and diagnosed using the Kidney Disease: Improving Global Outcomes (KDIGO) classification. Results: AKI was diagnosed in 230 (36.3%) patients. Multiple logistic regression analysis was performed to determine the independent predictors of AKI development. Proteinuria (odds ratio [OR] and 95% confidence interval [CI], 1.066 [1.002-1.135]; P=0.043) and low preoperative serum albumin levels (OR and 95% CI, 0.453 [0.216-0.947]; P=0.035) were found to be independent predictors of AKI. According to the receiver operating characteristic curve analysis, albumin level <3mg/dL (area under the curve: 0.621 [0.572-0.669], P<0.001) had 83% sensitivity and 10% specificity on predicting the development of AKI. Conclusion: We observed that a preoperative low serum albumin level was associated with postoperative AKI development in patients with DM who underwent isolated CABG procedure. We emphasize that this adjustable albumin level should be considered before the operation since it is an easy and clinically implementable management for the prevention of AKI development.

BACKGROUND: Hypoplastic left heart syndrome is a lethal congenital heart malformation when untreated resulting in a 95% mortality in the first month of life. In this study, we aimed to investigate the newly introduced inflammatory biomarker, neutrophil-lymphocyte ratio, as a mortality predictor in postoperative hypoplastic left heart syndrome patients. METHODS: Patients were divided into two groups; Group 1 consisted of 33 patients who were discharged and Group 2 including 20 patients who were deceased following surgery. Patients' preoperative demographic characteristics, total white blood cell counts, neutrophil counts, lymphocyte counts, neutrophil-lymphocyte ratio, C-reactive proteins, alanine aminotransferase, aspartate transaminase, urea, and creatinine levels were recorded. Studys' primary endpoint was all-cause patient mortality following surgery. RESULTS: The preoperative neutrophil-lymphocyte ratio was found to be significantly different between the groups (p = 0.001). High neutrophil-lymphocyte ratio was found to be associated with an increased risk of death. The ROC curves of neutrophil-lymphocyte ratio were found to be associated with mortality. The area under curve for the preoperative neutrophil-lymphocyte ratio was 0.74. Neutrophil-lymphocyte ratio predicted mortality with a sensitivity of 78% and a specificity of 65%. CONCLUSION: Neutrophil-lymphocyte ratio can contribute to the early identification of patients at high risk for complications. In addition, through the use of NLR, clinicians could implement measures for the optimal therapeutic approach of cardiac surgery patients and the elimination of adverse patient outcomes.

BACKGROUND: Coronary artery bypass grafting is applicable with very low mortality and morbidity rates around the world. However, exposure to even one of the risk factors increases mortality and morbidity significantly. There are three acute kidney injury definitions, and classification methods are applicable (Kidney Disease: Improving Global Outcomes (KDIGO); Risk, Injury, Failure, Loss of kidney function and End-stage kidney disease (RIFLE);" (for accuracy) and Acute Kidney Injury Network (AKIN)), for understanding and grading of renal impairment. With these definitions, it became possible to take measures at an early stage and start the management process. Methods for assessing renal impairment after coronary artery bypass grafting (CABG) specifically in patients with diabetes mellitus require further investigation. We compared these three acute kidney injury definitions for prediction of outcomes in diabetic patients undergoing coronary artery bypass grafting procedure. METHODS: Between January 2010 and December 2013, a total of 617 consecutive patients with diabetes mellitus undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass in our institution were included in the study. RESULTS: We considered 617 CABG operations on diabetes mellitus patients for this study from January 2010 to December 2013. The three scores provided good discriminative capacity in the global patient sample, with the area under the ROC curve (AUC) being higher, RIFLE (0.803, 95% CI: 0.724-0.882). The goodness of fit was good for all scales. CONCLUSIONS: Especially in on-pump CABG patients with diabetes mellitus, we can use AKIN, RIFLE, and KDIGO scoring systems to predict early diagnosis for acute kidney injury (AKI). In our analysis, the KDIGO criterion was superior to AKIN and RIFLE with regard its prognostic power.

Background/aim: Alprostadil and iloprost are successful agents used for both pulmonary hypertension and extremity ischemia treatment. Different systemic effects of these agents may change the preferences of clinical usage. Superiority of preventing ischemia/ reperfusion (IR) injury is a criterion for clinical preference of these agents. The present study was designed to compare the protective effects of alprostadil and iloprost in a rat model of IR injury. Materials and methods: Twenty-three male Sprague Dawley rats were used (aged 8-12 weeks, mean weight 230 ± 30 g). They were randomized into 4 groups: Group 1 (iloprost + IR), Group 2 (alprostadil + IR), Group 3 (saline + IR), and Group 4 (control). Under general anesthesia, in all groups except Group 4, the abdominal region was explored and the abdominal aorta was temporarily clamped for 60 min. After the clamp was removed, 120 min of reperfusion was applied. In Group 4, the rats were placed under general anesthesia and abdominal exploration was performed without the IR procedure. For all rats, body temperature was kept at 36 °C with a heater pad through the whole procedure. The rats were euthanized under general anesthesia to remove the kidneys and lungs for study. Histopathological and biochemical analyses were conducted with kidney and lung tissues. Histopathological scoring was done by analyzing cellular damage at tissue level. Malondialdehyde (MDA), superoxide dismutase, and glutathione levels were studied for biochemical analysis. Results: Histopathologic analysis showed that, as compared with alprostadil, iloprost provided a significantly higher level of renal protection against IR injury (P < 0.01). Renal tissue levels of MDA were significantly lower in the alprostadil group as compared to Group 3 (P < 0.05). Conclusion: Alprostadil and iloprost seem to provide protection against IR injury, with iloprost being more protective in renal tissue. Alprostadil is more effective than iloprost in protecting lung tissue against IR injury.
RESUMEN
Objective: Acute kidney injury after cardiac surgery is associated with mortality and morbidity. Therefore, strategies to prevent acute kidney injury are very important. The aim of this placebo-controlled randomized double-blind study was to compare the prophylactic efficacy of N-Acetylcysteine and dopamine administration in patients with pre-existing moderate renal insufficiency who were undergoing cardiopulmonary bypass. Methods: This study included 135 patients with pre-existing moderate renal insufficiency who were scheduled for coronary artery bypass grafting surgery. Serum creatinine and GFR were recorded preoperatively and on the first and second postoperative days. Results: On the first and second postoperative days, the drugs used showed statistically significant differences among the creatinine groups (P<0.001). According to Tukey's HSD, on the first and second PO, the creatinine of Group N, D and P were significantly different (P<0.001). On the first and second PO, the used drugs showed statistically significant differences among the effects of eGFR (P<0.001). According to Tukey's HSD on the first postoperative day, the average eGFR score of Group N compared to D and P were significantly difference (P<0.001). On the second postoperative day, the eGFR of Group N and D showed no difference (P=0.37), but P showed a difference (P<0.001). Conclusion: We found that the prophylactic use of intravenous N-Acetylcysteine had a protective effect on renal function, whereas the application of renal dose dopamine did not have a protective effect in patients with pre-existing moderate renal failure.

INTRODUCTION: Coronary artery bypass grafting (CABG) results in higher morbidity and mortality rates in end-stage renal disease (ESRD) patient populations than in patients with normal renal function. This study aimed to identify the early results of CABG performed on ESRD patients, and the factors that affected the mortality rates of those patients. METHODS: A retrospective evaluation of our hospital database revealed 84 haemodialysis-receiving patients who underwent CABG during the years 2006 to 2012. Mortality was observed in 21 patients (group 1), and this group was compared with the remaining patients (group 2) for peri-operative parameters such as age, EuroSCORE, functional capacity, myocardial infarction, use of inotropes and completeness of revascularisation. RESULTS: The study included 60 male (71.4%) and 24 female patients (28.6%); the participants' mean age was 59.50 ± 9.93 years. The pre-operative additive EuroSCORE was 7.96 ± 2.88 (range: 2-18). Pre-operative functional capacity was impaired in 35.7% of the patients [New York Heart Association (NYHA) classes III-IV]. Mean age and preoperative EuroSCORE values of group 1 were significantly higher than those of group 2. Impaired functional capacity (NHYA classes III-IV) was also associated with mortality (OR: 3.333; 95% CI: 1.199-9.268). Fifty-four patients (64.3%) underwent on-pump CABG procedures, and 30 (35.7%) underwent off-pump CABG procedures. The study found no statistically significant difference in mortality rates between these two techniques. Mortality occurred in 12 patients (22.2%) in the on-pump group and in nine (30%) in the off-pump group. Complete revascularisation was performed on 46 patients (85.2%) in the on-pump group and seven (23.3%) in the off-pump group (p < 0.001). CONCLUSION: Advanced age, impaired NYHA functional capacity and pre-operative hypertension were determinative for early-term surgical mortality. An on-pump surgical technique is recommended to ensure completeness of revascularisation.

Background/aim: The aim of this prospective study was to determine whether the preoperative oral intake of carbohydrate-rich drinks by patients undergoing a coronary artery bypass graft attenuates postoperative insulin requirements, improves postoperative patient discomfort, provides inotropic support, shortens the length of the ICU stay, and shortens the duration of postoperative mechanical ventilation. Materials and methods: This randomized prospective clinical study included 152 patients with coronary artery disease who were divided into 4 groups. Carbohydrates were administered to 3 groups at different hours and doses before operation. The fourth group had an 8-h preoperative fasting period. The inotropic and vasopressor requirements, ventilation time, and ICU stay time were recorded for all of the groups. Patient wellbeing, mouth dryness, hunger, anxiety, and nausea were assessed using VAS scores of 1-10. Results: Mouth dryness and hunger were significantly higher in the control group (P = 0.03, P = 0.02). The increase in blood glucose level was significantly higher in the control group (P = 0.04). The exogenous insulin requirement was significantly higher in the control group than in the other groups (P = 0.04). Conclusion: The administration of carbohydrates before elective cardiac surgery reduced insulin resistance. Based on the VAS scores, the intake of carbohydrates reduced mouth dryness and hunger. Overall, preoperative oral carbohydrate treatments can improve the postoperative outcomes of coronary artery bypass graft surgeries.

The aim of this study is to evaluate the incidence and predictors of silent neuronal injury (SNI) after coronary angiography (CAG) and intervention by serial measurement of serum neuron-specific enolase (NSE) in patients presented with acute coronary syndrome (ACS). Ninety-eight consecutive patients presented with ACS and underwent CAG and intervention were included in the study. The NSE levels significantly increased after CAG and intervention compared to baseline levels (22.03 ± 27.70 and 10.08 ± 3.15 consecutively). Left ventricular ejection fraction in the SNI+ group was significantly lower than that in the SNI- group (43.71% ± 12.51%, 50.84% ± 9.34%, P = .002). Maximal creatinine kinase myocardial band, troponin I, and SYNTAX score of the SNI+ group were significantly higher than those of the SNI- group (103.83 ± 99.22, 51.92 ± 78.33, P = .006; 50.04 ± 66.18, 19.18 ± 30.50, P = .002; 103.83 ± 99.22, 51.92 ± 78.33, P = .006; and 50.04 ± 66.18, 19.18 ± 30.50, P = .002 successively). SYNTAX score and performing percutaneous coronary intervention were the independent predictors of SNI (P = .009, odds ratio [OR] = 1.06, 95% confidence interval [CI] = 1.014-1.107, P = .036, OR = 4.262, 95% CI = 1.097-16.56). Percutaneous coronary intervention and coronary artery lesion complexity may increase the risk of SNI in patients with ACS.

A 45-year-old male being otherwise healthy presented acute onset of right upper extremity ischemia. On physical examination, axillary artery could be palpated whereas the brachial artery could not be palpated below the level of the antecubital fossa, including radial and ulnar artery pulses. Pulses were also inaudible with pocket-ultrasound below the level of the brachial artery bifurcation. The patient was initially diagnosed to have acute thromboembolic occlusion and given 5000 IU intravenous heparin. The patient was taken to the operating room. We noticed that the ischemic symptoms disappeared within a couple of minutes just before we began the operation. However, ischemic symptoms reappeared six hours later and computed tomography angiography showed lack of enhancement below the elbow crease. We were taking the patient to the operating room for the second time when the symptoms recovered in a few minutes, again. The operation was not canceled anymore. In the operation, the brachial artery was found anomalously perforating and it was entrapped by the bicipital aponeurosis. The artery was relieved by resecting the aponeurosis and there was no need for any other intervention. The patient had no more recurrence of symptoms postoperatively.
