Abstract
Abstract
Background and aim
Systemic vascular resistance (SVR) is useful for risk estimation and therapy guidance in HF. It has been showed that the ratio of peak mitral regurgitation velocity (MRV) to left ventricular outflow tract velocity-time integral (LVOT VTI) correlated positively with SVR. We aimed to assess the association of MRV/LVOT VTI ratio with established prognostic markers and its prognostic role for predicting one year and long term composite end-points in patients with HF and reduced ejection fraction (HFrEF).
Material and methods
We prospectively enrolled a total of 72 patients with HFrEF and 10 control subjects. Patients were followed up patients for median 40.5 months. Primary composite endpoint (CEP) was defined as any of these outcomes including requiring mechanical circulatory support, cardiac transplantation and all-cause mortality.
Results
CEP(+) patients had higher MRV/LVOT VTI ratio than others (0.48±0.15 vs. 0.39±0.18 p=0.012). MRV/LVOT VTI ratio was positively correlated with functional status (β=0.539, p=0<001), serum BNP level (β=0.479, p<0.001),troponin I (β=0.415, p<0.001), and Uric acid level (β=0.235 p=0.018) and negatively correlated with SEATTLE score derived life expectancy (β=−0.248, p=0.032). Adjusted with other parameters, every 0.1 increase in MRV/LVOT VTI ratio increased the one-year CEP risk by 27% and long-term CEP risk by 24.6%. In Kaplan Meier analysis, patients with MRV/LVOTVTI ratio ≥0.39 had more long-term CEP compared to others.
Conclusion
MRV/LVOT VTI ratio seemed to be useful predictor of poor prognosis associated with other established HF prognostic markers.

Abstract
Abstract
Background and aim
Coronary sinus (CS) as an intrapericardial, low-pressure, thin-walled structure can be easily compressed in cardiac tamponade. Whereas, inferior vena cava (IVC) is an extrapericardial structure which dilates in tamponade as opposed to the response of CS. The inverse relationship between these two venous structures may augment their role in the evaluation of tamponade imaging. Therefore, we assessed the usefullness of computerized tomographic measures of CS diameter, and also CS to IVC ratio (CS/IVC) to predict tamponade in clinically stable patients with large pericardial effusion.
Materials and methods
66 clinically stable patients who had large pericardial effusions, were included to the study. CS diameter was measured from the point at 1 cm proximal to the CS ostium11. IVC diameter was measured from the segment between its right atrial orifice and hepatic vein.
Results
Patients with tamponade had 40% smaller CS diameter (5.3±1.8 vs 8.8±2.6 mm p<0.001) and 35% lower CS/IVC ratio (20.7±5.5 vs 34.7±10.5% p<0.001).After adjusting with other parameters, only either CS diameter or CS/IVC ratio predicted tamponade respectively. (Nagelkerke r square value for CS diameter was 53.7% and 72.1% for CS/IVC ratio). 1 mm increase in CS diameter and 1% increase in CS/IVC ratio were associated with an increased odds ratio of 59% and 39% in predicting tamponade, respectively (p value <0.001).In ROC analysis, a cut of value of 6.85 mm for CS diameter, had 82.6% sensitivity and 83.7% specificity for predicting cardiac tamponade (Area under the curve 0.879, p<0.001). Additionally, a cut of value of 27% for CS / IVC ratio had 87.0% sensitivity and 86.0% specificity for predicting cardiac tamponade (Area under the curve 0.945, p<0.001).
Conclusion
The tomographic measures of both the CS diameter and the CS/IVC ratio predicted tamponade in clinically stable patients with large pericardial effusion. Compared with CS diameter, CS/IVC ratio seemed to be a more powerful predictor of tamponade

Abstract
Abstract
Background
As a risk factor for developing heart failure, metabolic syndrome (MetS) is associated with a reduced heart failure mortality. This paradox is also seen in most of the chronic diseases and also in the elderly population. Parameter changes representing the deteriarion of the balance in favor of catabolism including the low body mass index (BMI) and low blood pressure as well as low blood cholesterol have been associated with poor prognosis in several populations. Apart from high-density lipoprotein, which is further decreased, inverted changes in the components of MetS have been seen in heart failure population which led to the introduction of the concept of the “reverse metabolic syndrome” (RMetS).
Purpose
We aimed to investigate the effect of MetS and RMetS on hemodynamic parameters and long-term prognosis in patients with heart failure and reduced ejection fraction (HFrEF).
Methods
400 consecutive patients who were followed with HFrEF and performed right heart catheterization were examined. 96 patients with cardiac cachexia and morbid obesity were excluded and the remaining 304 patients with BMI 18–40 kg/m2 were included. The presence of MetS is defined according to the NCEP-ATP III criteria. RMetS was accepted as having BMI <22 kg/m2 with total cholesterol level <160 mg/dL and/or systolic or diastolic blood pressures <110 mmHg and <70 mmHg respectively. Composite endpoint (CEP) was defined as either of the occurrence of all-cause mortality, assist device implantation or cardiac transplantation. Endpoints were analyzed in two step approach: first we grouped patients accoding to the presence of MetS, then we added the RMetS category and stratifed patients into three groups as metabolic syndrome, reverse metabolic syndrome and metabolic healthy
Results
304 patients were followed up for a median of 16 (0–48) months. 110 patients had all-cause mortality and 148 patients had CEP. In the first step, patients with MetS (110 patients) had reduced all-cause mortality and CEP than patients without MetS (194 patients). In the second step, RMetS group had the highest all-cause mortality and CEP (chi-square: 22.187 p<0.001 and chi-square: 30.980, p<0.001, respectively) Cardiac output, cardiac index were lower and PCWP was higher in RMetS group. The endpoints were similar between MetS group and metabolically healthy patients.
Conclusion
Although individuals with MetS seem to have a better prognosis than patients without MetS, the latter group contains RMetS population, which had the poorest prognosis. This population may contribute to the false- assumption of the relative better findings of MetS population with regard to the non-MetS population. Further clinical studies are needed to clarify this pathologic phenomenon.

Abstract
BACKGROUND AND AIM Coronary slow flow phenomenon (CSFP) is a miscellaneous clinical entity leading to angina-like symptoms, and electrocardiographic and scintigraphic evidence of ischemia. The impact of this syndrome on myocardial performance has not been comprehensively evaluated. In this study, we sought to evaluate the myocardial energy expenditure (MEE) in patients with CSFP and its relationship with exercise capacity. METHODS AND RESULTS A total of 64 patients (64.1% male, mean age 53.2 ± 10.3 years) with CSFP and 64 patients (60.9% male, mean age 52.2 ± 10.9 years) with normal coronary artery as control group were included. MEE was calculated by a validated formula that uses transthoracic echocardiography (TTE) parameters, including left ventricular circumferential end-systolic stress, stroke volume, and ejection time CSFP patients had significantly lower MEE (0.79 cal/systole ± 0.15 vs. 0.91 cal/systole ± 0.09, p < 0.001). In correlation analysis, MEE had a significant negative correlation with mean corrected TIMI frame count (mTFC) (β = -0.523; p < 0.001) and positive correlations with metabolic equivalents (METs) (β = 0.560; p < 0.001), rate pressure product (β = 0.649; p < 0.001), and exercise duration (β = 0.408; p < 0.001). At multivariate analysis, MEE was demonstrated as an independent predictor of CSFP (OR 1.863, CI 95% 1.485-2.338 p < 0.001). CONCLUSION Myocardial energy consumption, as a calculation obtained from TTE parameters, was reduced in patients with CSFP, and it had a significant relationship with exercise capacity. Considering its significant correlation with exercise capacity, myocardial energy consumption seemed to use evaluation of myocardial performance and functional status in another cardiovascular disease.

Abstract
BACKGROUND It is clinically important to evaluate the severity of right ventricular (RV) overload in patients with chronic obstructive pulmonary disease (COPD), which is often associated with changes in the structure and the function of the right ventricle. Noninvasive and reliable assessment of RV function would be an essential determinant of RV load and a clinically useful factor for assessing cardiovascular risk in COPD patients. OBJECTIVE The aim of this study was to investigate the clinical application value of right ventricular outflow tract (RVOT) systolic function measured by transthoracic echocardiography in patients with COPD. PATIENTS AND METHODS We prospectively investigated COPD male patients and compared them with healthy controls. In addition to RV conventional echocardiographic parameters, RVOT size and fractional shortening (RVOT-FS) parameters were also assessed. RESULTS Fifty-five COPD patients (all men; mean age, 62 ± 9 years) participated in the study, and were compared with a control group consisting of 21male, healthy, nonsmoking subjects with a mean age of 58 ± 11 years. The RVOT-FS was impaired in COPD patients than healthy controls (27.8 ± 15.5 vs. 57.5 ± 8.6, p < 0.001), and was correlated positively with tricuspid annular plane systolic excursion (TAPSE; r = 0.583, p < 0.001) and pulmonary acceleration time (r = 0.666, p < 0.001) and inversely with pulmonary artery systolic pressure (r = 0.605, p < 0.001) and functional capacity(r = - 0.589, p < 0.001). There was a statistically significant difference in RVOT-FS among the COPD subgroups with regard to New York Heart Association functional classification (p < 0.001). CONCLUSION The RVOT-FS is a noninvasive easily applicable measure of RV systolic function and is well correlated with functional capacity in COPD patients. Its combination with long-axis measurements via TAPSE and transtricuspid Doppler analysis may provide a comprehensive evaluation of the RV performance in COPD patients.

Abstract
BACKGROUND Prevention from postoperative pulmonary complications (PPCs) has been an important topic. The aims of this study were to determine the risk factors for PPC after liver surgery and to analyze the efficacy of postoperative pulmonary care on PPC prevention. MATERIALS AND METHODS We retrospectively analyzed variables of 81 patients who underwent hepatectomy and 4 transplantations between January 2007 and March 2012. RESULTS Nineteen patients suffered PPCs (22.4%). Bivariate analysis identified four risk factors: preoperative anemia (odds ratio [OR] = 5.69), the American Society of Anesthesiologists (ASA) score of 3 or 4 (OR = 5.36), blood transfusion (OR = 2.81), and prolonged operative time (OR = 1.01). Upon multivariate analysis, only prolonged operative time was an independent risk factor for PPC (OR = 1.01). Pulmonary function test (PFT) was performed for 22 of 41 patients with an ASA score ≥ 2 (53.7%); there was no significant relationship between abnormal PFTs (n = 13) and the development of PPCs (P = .12). CONCLUSIONS The elimination of risk factors may reduce the incidence of PPCs. Postoperative intensive pulmonary care should be given to all patients after liver surgery but particularly to patients with high ASA scores and those with abnormal PFTs irrespective of age.

Abstract
BACKGROUND Total vascular exclusion (TVE) causes warm liver ischemia. The aim of this study was to investigate the patterns of injury caused by inflow-outflow obstruction in the rat liver. MATERIALS AND METHODS Twenty-four Wistar-Albino rats were divided into three groups: liver inflow occlusion (Group A), inflow-outflow occlusion (Group B) and intermittent inflow-outflow occlusion applied for 15 minutes. Microcirculation was measured with laser Doppler flowmetry during the procedure. Samples for biochemical and histopathological analyses were collected at the end of the ischemia period. RESULTS Significant alterations in microcirculation were determined by application of vascular control maneuvers. Microcirculation in the central and dome segments were affected adversely compared with the dome segments in all experimental groups. TVE induced severe disturbances in hepatic microcirculation with more prominent hepatocellular damage. Damage to central segments of the rat liver was more prominent with inflow occlusion; whereas inflow-outflow occlusion produced more prominent damage to dome segments. Intermittent application of TVE clamping was associated with more hepatocellular damage compared with continuous TVE. CONCLUSION Our mapping methodology within the liver parenchyma suggested that hepatovenous back-perfusion is a principle source of continuity of microcirculation in the rat liver during inflow occlusion. Inflow-outflow occlusion caused more tissue damage compared with inflow occlusion. Ischemic preconditioning during TVE did not increase the tolerance of the liver against ischemia.

Abstract
We present GaAs electroluminescent nanowire structures fabricated by metal organic vapor phase epitaxy. Electroluminescent structures were realized in both axial pn-junctions in single GaAs nanowires and free-standing nanowire arrays with a pn-junction formed between nanowires and substrate, respectively. The electroluminescence emission peak from single nanowire pn-junctions at 10 K was registered at an energy of around 1.32 eV and shifted to 1.4 eV with an increasing current. The line is attributed to the recombination in the compensated region present in the nanowire due to the memory effect of the vapor-liquid-solid growth mechanism. Arrayed nanowire electroluminescent structures with a pn-junction formed between nanowires and substrate demonstrated at 5 K a strong electroluminescence peak at 1.488 eV and two shoulder peaks at 1.455 and 1.519 eV. The main emission line was attributed to the recombination in the p-doped GaAs. The other two lines correspond to the tunneling-assisted photon emission and band-edge recombination in the abrupt junction, respectively. Electroluminescence spectra are compared with the micro-photoluminescence spectra taken along the single p-, n- and single nanowire pn-junctions to find the origin of the electroluminescence peaks, the distribution of doping species and the sharpness of the junctions.

Abstract
BACKGROUND Technical modifications and methods for gallbladder dissection to minimize the risk of gallbladder perforation during laparoscopic cholecystectomy (LC) are described. The authors aimed to investigate the effects of gallbladder aspiration during LC on the operative and postoperative course of patients. METHODS For this study, 200 patients undergoing LC for symptomatic cholelithiasis were randomly divided into two groups. Gallbladders were aspirated before dissection in group A (n = 100), and they were not aspirated in group B (n = 100). Operative and postoperative data on the patients were collected. RESULTS The rate of gallbladder perforation was significantly lower in group A than in group B (p = 0.0003). The operative time was significantly shorter in group A (46.70 +/- 15.93 min) than in group B (60.75 +/- 22.09 min) (p = 0.047). Postoperative complications were more numerous in group B. The hospital stay was significantly longer in group B (1.55 +/- 0.81 days) than in group A (1.3 +/- 0.5 days; p = 0.004). CONCLUSION The findings demonstrate the advantages of gallbladder aspiration in elective cases.

Abstract
Two cases of acute pericarditis presented with interesting electrocardiograms resembling Brugada-like or early repolarisation patterns. This report emphasises that proper interpretation of the electrocardiogram in patients with ST-segment elevation assists the clinician in arriving at the correct diagnosis in making appropriate diagnostic and therapeutic decisions, and also that the saddleback-type ST-segment elevation cannot be a sensitive finding for the Brugada syndrome.

Abstract
BACKGROUND Total vascular exclusion (TVE) causes warm liver ischemia. The complete explanation of the events during inflow and outflow obstruction of the liver during selective TVE has not yet been studied. The aim of this study was to investigate the liver injury caused by inflow-outflow obstruction in the rat liver. MATERIALS AND METHODS Forty Wistar-Albino rats were divided into four groups. Liver inflow occlusion (groups A and C) or inflow-outflow occlusion (groups B and D) was applied for 30 minutes. Samples were collected at the end of the ischemia period. We examined oxidative injury in the liver tissue and liver histopathology. RESULTS Oxidative stress and histopathologic alterations were more prominent with TVE application. Significant alterations were shown in hepatic superoxide dismutase, glutathione, and glutathione S-transferase levels. Central segments of the rat liver were affected significantly from inflow occlusion, whereas dome segments were significantly damaged from inflow-outflow occlusion. CONCLUSIONS Inflow-outflow occlusion of the liver caused more tissue damage compared with inflow occlusion. The pattern of distribution of the damage due to TVE seemed different from other well-known ischemia-reperfusion injuries.

Abstract
INTRODUCTION The aim of this study was to investigate the effects of total vascular exclusion (TVE) on the liver during the early period of reperfusion. MATERIALS AND METHODS Forty Wistar-Albino rats were divided into four groups. Portal pedicle clamping (groups 1 and 2) or TVE (groups 3 and 4) were applied for 10 minutes. Samples were collected at the time of clamp release (groups 1 and 3) and at 30 minutes of reperfusion (groups 2 and 4). We examined oxidative injury to and histopathology of the liver. RESULTS Oxidative stress was more prominent with TVE application. Significant alterations were shown in hepatic superoxide dismutase, catalase, glutathione, and glutathione S-transferase levels. The levels of malondialdehyde and myeloperoxidase were not altered significantly. CONCLUSION Inflow-outflow occlusion of the liver causes more oxidative stress compared with inflow occlusion.

Abstract
INTRODUCTION The aim of this study was to investigate the effects of dimethyl sulfoxide on liver damage caused by ischemia-reperfusion after portal vein clamping. MATERIAL AND METHODS Forty New Zealand rabbits were divided into three groups with the portal veins of all the rabbits except the sham group clamped for 30 minutes: group I, sham procedure; group II, control group; and group III, 500 mg/kg DMSO. The drug was administered IM in the left inguinal region 30 minutes before the operation. Blood samples (5 mL) were taken from the animals at 15, 30, and 45 minutes. At the end of the experiment 1 g of liver tissue samples were obtained. Malondialdhyde (MDA), nitric oxide (NO), AST, ALT, and LDH plasma levels were measured in the blood samples. Liver tissue samples stained with hematoxylin eosin were examined under light microscopy for histopathological changes. FINDING The liver enzymes in both clamping groups increased significantly compared with the sham group (P < .01). Enzyme levels of the DMSO group decreased significantly compared to the control clamping group (P < .05). Similar to the enzyme changes, MDA and NO levels increased in the portal vein clamping versus the sham group and decreased in the drug-administered group versus the control clamped group (P < .03). The severity of histopathological changes was less in the DMSO group than in the clamped controls. CONCLUSION DMSO decreased the severity of liver damage after portal vein clamping.

Abstract
Increasing experience with transhiatal esophagectomy (THE) has brought with it a good understanding of the advantages and disadvantages of the technique. As in our case, diaphragmatic hernias after THE may result from excess manipulation and extension of the hiatus during surgery. The varying nature of the clinical presentation may cause delay in diagnosis. We report our case and discuss how to diagnose and manage this complication under the sum of cases reported previously in English literature.
