RESUMEN
INTRODUCTION: The aim of this study was to assess the impact of aortic angulation (AA) on periprocedural and in-hospital complications as well as mortality of patients undergoing Evolut™ R valve implantation. METHODS: A retrospective study was conducted on 264 patients who underwent transfemoral-approach transcatheter aortic valve replacement with self-expandable valve at our hospital between August 2015 and August 2022. These patients underwent multislice computer tomography scans to evaluate AA. Transcatheter aortic valve replacement endpoints, device success, and clinical events were assessed according to the definitions provided by the Valve Academic Research Consortium-3. Cumulative events included paravalvular leak, permanent pacemaker implantation, new-onset stroke, and in-hospital mortality. Patients were divided into two groups, AA ≤ 48° and AA > 48°, based on the mean AA measurement (48.3±8.8) on multislice computer tomography. RESULTS: Multivariable logistic regression analysis was performed to identify predictors of cumulative events, utilizing variables with a P-value < 0.2 obtained from univariable logistic regression analysis, including AA, age, hypertension, chronic renal failure, and heart failure. AA (odds ratio [OR]: 1.73, 95% confidence interval [CI]: 0.89-3.38, P=0.104), age (OR: 1.04, 95% CI: 0.99-1.10, P=0.099), hypertension (OR: 1.66, 95% CI: 0.82-3.33, P=0.155), chronic renal failure (OR: 1.82, 95% CI: 0.92-3.61, P=0.084), and heart failure (OR: 0.57, 95% CI: 0.27-1.21, P=0.145) were not found to be significantly associated with cumulative events in the multivariable logistic regression analysis. CONCLUSION: This study demonstrated that increased AA does not have a significant impact on intraprocedural and periprocedural complications of patients with new generation self-expandable valves implanted.

BACKGROUND: Cardiac implantable electronic device (CIED) procedures are prone to complications. In our study, we investigated the effect of body mass index (BMI) on CIED-related complications. METHODS: 1676 patients who had undergone CIED surgery (de novo implantation, system upgrade, generator change, pocket revision or lead replacement) at two heart centers in Turkey and met the study criteria were included in our study. For analysis of primary and secondary endpoints, patients were classified as non-obese (BMI < 25 kg/m2 ), overweight (25 ≤ BMI < 30 kg/m2 ), and obese (BMI ≥ 30 kg/m2 ). The primary endpoint was accepted as cumulative events, including the composite of clinically significant hematoma (CSH), pericardial effusion or tamponade, pneumothorax, and infection related to the device system. Secondary outcomes included each component of cumulative events. RESULTS: The rate of cumulative events, defined as primary outcome, was higher in the obese patient group, and we found a significant difference between the groups (3.0%, 4.3%, 8.9%, p = .001). CSH and pneumothorax rates were significantly higher in the obese patient group (0.3%, 0.9%, 1.9%, p = .04; 1.0%, 1.4%, 3.3%, p = .04, respectively). According to our multivariate model analysis; gender (OR:1.882, 95%CI:1.156-3.064, p = .01), hypertension (OR:4.768, 95%CI:2.470-9.204, p < .001), BMI (OR:1.069, 95%CI:1.012-1.129, p = .01) were independent predictors of cumulative events rates. CONCLUSIONS: Periprocedural complications associated with CIED (especially hematoma and pneumothorax) are more common in the group with high BMI.

RESUMEN
AIM: Blunt traumatic thoracic aortic injury (BTAI) is a highly fatal surgical emergency and is treated with endovascular procedures. We aimed to analyze and report the early and midterm outcomes of surgeon-modified fenestrated stent-grafts (SMFSG) compared with other conventional endovascular methods in patients with BTAI repaired with zone 2 endovascular surgery. MATERIALS AND METHODS: Before and after the study was performed, from January 2015 to January 2020 for a period in which conventional endovascular treatments were used and from January 2020 to January 2023 for the second period in which the SMFSG technique was used. A total of 25 patients who underwent zone 2 endovascular repair for BTAI were included. The patients treated with conventional endovascular methods in the first period, chimney thoracic endovascular aortic repair (TEVAR) (n=3 patients); Left subclavian artery (LSA)-covered (intentionally total) (n=12 patients) LSA-covered (LSAC) TEVAR; carotid-subclavian bypass TEVAR (n=2 patients) was defined as group 1, and the group of patients treated with SMFSG in the second period was defined as group 2. The primary endpoints of the study were technical success, defined as complete closure of BTAI, and in-hospital mortality. Secondary outcomes were aortic pathology-related morbidity, mortality, and re-interventions during the follow-up period. RESULTS: The mean age was 42.6±14.3 years, and 21 (84%) of the patients were male. The patients were compared with respect to the proximal landing zone, fluoroscopy time, duration of the procedure, length of intensive care unit stay, and hospital stay, no statistically significant difference was found between the 2 groups (p>0.05). The mean follow-up time of patients in group I was 46±9 months, while in group II, it was 14±6 months (p<0.001). While no TEVAR-related complications were detected in group II throughout follow-up, they occurred in 4 patients (28.6%) in group I. CONCLUSION: TEVAR is the most appropriate treatment for BTAI in the modern era, especially for polytrauma patients with successful outcomes. Intentional coverage of the LSA can be performed, but SMFSG is an effective, economical, rapid, and available technique for endovascular revascularization of the LSA. CLINICAL IMPACT: Altough intentional left subclavian artery coverage is preferred routinely in patients with blunt traumatic aortic injury (in Zone 2) which is a highly fatal surgical emergency, surgeon-modified fenestrated stent-grafts is also effective, economical, rapid and available technique.
RESUMEN
OBJECTIVE: The aim of our study was to compare the traditional radial artery, distal radial artery, and transfemoral artery, which are vascular access sites for coronary angiography, in terms of pain level using the visual analog scale. METHODS: Between April 2021 and May 2022, consecutive patients from three centers were included in our study. A total of 540 patients, 180 from each of the traditional radial artery, distal radial artery , and transfemoral artery groups, were included. The visual analog scale was applied to the patients as soon as they were taken to bed. RESULTS: When the visual analog scale was compared between the groups, it was found to be significantly different (transfemoral artery: 2.7±1.6, traditional radial artery: 3.9±1.9, and distal radial artery: 4.9±2.1, respectively, p<0.001). When the patients were classified as mild, moderate, and severe based on the visual analog scale score, a significant difference was found between the groups in terms of body mass index, process time, access time, and number of punctures (p<0.001). Based on the receiver operating characteristic analysis, body mass index>29.8 kg/m2 predicted severe pain with 72.5% sensitivity and 73.2% specificity [(area under the curve: 0.770, 95%CI: 0.724-0.815, p<0.0001)]. CONCLUSION: In our study, we found that the femoral approach caused less access site pain and a high body mass index predicts severe pain.

BACKGROUND: The aim of the study is to compare the results of patients who had moderate or severe tricuspid insufficiency (TI) at the time of left ventricular assist device (LVAD) implantation that did not undergo intervention. METHODS: Between October 2013 and December 2019, 144 patients who did not undergo tricuspid valve repair (TVR) during LVAD implantation in our department were included in the study. The patients were divided into two groups according to the TI grade; Group 1: 106 patients (73.6%) with moderate TI and Group 2: 38 patients (26.4%) with severe TI. All patients were evaluated for mortality, need of inotrope, blood product transfusion, intensive care unit (ICU) stay, duration of mechanical ventilation, and early and late right ventricular failure (RVF). Minimally invasive technique was favored in patients with worse right ventricular (RV) function to prevent the need for postoperative RV support and bleeding. RESULTS: The mean ages of the patients in the Group 1 and Group 2 were 46 ± 15 years (82% male), and 45 ± 11.2 years (81.5% males), respectively. Post-operative duration of mechanical ventilation, ICU stay, blood loss, and reoperations were similar (p > 0.05). There was no significant difference in early RVF, pump thrombosis, stroke, bleeding, and 30-day mortality between groups (p > 0.05). Incidence of late RVF was higher in Group 2 (p < 0.05). CONCLUSION: Although the risk of late RVF may increase in patients with preoperative severe TI, not intervening in TI during LVAD implantation does not cause adverse clinical outcomes in the early period.

Abstract Background: Coronary artery ectasia (CAE) is defined by focal enlargement of the coronary artery exceeding 1.5 times the adjacent normal segment. CAE can often cause arrhythmias, heart failure, sudden death, and myocardial ischemia. Ischemia due to microvascular dysfunction may be responsible for the ventricular heterogeneity in CAE. Objectives: The aim of our study was to evaluate the frontal QRS-T angle in patients with CAE. Methods: Our study included 55 patients with CAE and 50 individuals in the control group. Demographic characteristics and electrocardiographic parameters were compared between the two groups. Categorical variables were compared using the chi-square test. Continuous variables were compared using unpaired Student's t-test. P values < 0.05 were considered statistically significant. The frontal QRS-T angle was calculated from 12-lead electrocardiograms (ECGs) using the automatic report from the electrocardiography machine. Results: The average age of patients with CAE was 63.2 ± 3.4 years, with 18 women among them. The control group had an average age of 61.1 ± 3.2 years, with 28 women included. There was no significant difference in demographic parameters between the two groups. Compared to the control group, patients with CAE had significantly wider frontal QRS-T angle (p < 0.001), as well as longer QTmax duration, p = 0.002; Tp-Te interval, p = 0.02; and QT dispersion (QTd), p = 0.04. Conclusion: The frontal QRS-T angle can be calculated easily and time-efficiently using surface electrocardiography. In this study, we showed for the first time that the frontal QRS-T angle was significantly increased in patients with CAE.
RESUMEN
Although transcatheter aortic valve replacement (TAVR) is safe and effective, mortality and bleeding events post procedure are important. The present study investigated the changes in hematologic parameters to evaluate whether they predict mortality or major bleeding. We enrolled 248 consecutive patients (44.8% male; mean age 79.0 ± 6.4 years) undergoing TAVR. In addition to demographic and clinical examination, blood parameters were recorded before TAVR, at discharge, 1 month and 1 year. Hemoglobin levels before TAVR 12.1 ± 1.8 g/dL, 10.8 ± 1.7 g/dL at discharge, 11.7 ± 1.7 g/dL at first month, 11.8 ± 1.4 g/dL at first year (Hemoglobin values compared with pre-TAVR, P < .001, P = .019, P = .047, respectively). Mean platelet volume (MPV) before TAVR 8.72 ± 1.71 fL, 8.16 ± 1.46 fL at discharge, 8.09 ± 1.44 fL at first month, 7.94 ± 1.18 fL at first year (MPV values compared with pre-TAVR, P < .001, P < .001, P < .001, respectively). Other hematologic parameters were also evaluated. Hemoglobin, platelet count, MPV, and red cell distribution width before the procedure, at discharge, and at the first year did not predict mortality and major bleeding in receiver operating characteristic analysis. After multivariate Cox regression analysis, hematologic parameters were not independent predictors of in-hospital mortality, major bleeding, and death at 1 year after TAVR.
RESUMEN
BACKGROUND: The most significant adverse effect of antithrombotic medication in acute coronary syndrome (ACS) is major bleeding, which is related to increased mortality. Studies on ORBIT risk score in predicting major bleeding in ACS patients are limited. OBJECTIVE: This research aimed to examine whether the ORBIT score calculated at the bedside can identify major bleeding risk in patients with ACS. METHODS: This research was retrospective, observational, and conducted at a single center. Analyses of receiver operating characteristics (ROC) were utilized to define the diagnostic value of CRUSADE and ORBIT scores. The predictive performances of the two scores were compared using DeLong's method. Discrimination and reclassification performances were evaluated by the integrated discrimination improvement (IDI), and net reclassification improvement (NRI). RESULTS: The study included 771 patients with ACS. The mean age was 68.7 ± 8.6 years, with 35.3 % females. 31 patients had major bleeding. Twenty-three of these patients were BARC 3 A, five were BARC 3 B, and three were BARC 3 C. Bleeding history [OR (95 % CI), 2.46 (1.02-5.94), p = 0.021], hemoglobin levels [OR (95 % CI), 0.54 (0.45-0.63), p < 0.001], and age > 74 years [OR (95 % CI), 1.03 (1.01-1.06), p = 0.039] were independent predictors of major bleeding. The ORBIT score was an independent predictor of major bleeding in the multivariate analysis: continuous variables [OR (95 % CI), 2.53 (2.61-3.95), p < 0.001] and risk categories [OR (95 % CI), 3.06 (1.69-5.52), p < 0.001]. Comparison of c-indexes for major bleeding events revealed a non-significant difference for the discriminative ability of the two tested scores (p = 0.07) with a continuous NRI of 6.6 % (p = 0.026) and an IDI of 4.2 % (p < 0.001). CONCLUSION: In ACS patients, the ORBIT score independently predicted major bleeding.

PURPOSE: The aim of this study is to investigate the efficacy of adaptation of right ventricular (RV) risk scores used in adult patients to pediatric age group undergoing LVAD implantation. METHODS: Twenty-two pediatric patients who underwent LVAD implantation were retrospectively reviewed from January 2014 to September 2018. Preoperative patient characteristics, hemodynamic parameters, and echocardiographic data were collected. Adult RV risk scores were calculated for all patients. Effects of all the parameters on RV function were also investigated. Study endpoints were RVF and in-hospital mortality. RESULTS: Eleven (50%) of 22 patients were male. The mean age of the patients was 13.4 ± 3.8 years. The mean body surface area of the patients was 1.4 ± 0.4 m2. In five patients BiVAD implantation was performed. Of these five BiVAD patients two underwent successful heart transplant; two weaned from temporary RVAD and last patient died due to multi-organ failure. Four patients showed signs of early RVF; one patient was transplanted successfully while on medical support. Three patients developing RVF did not respond medical therapy necessitating ECMO and died in the early postoperative period. All risk scores and potential predictive factors were evaluated individually and in combination of several parameters. No significant predictor for RVF in pediatric patients that underwent LVAD implantation was found (p > 0.05). CONCLUSION: Neither an adult risk score nor a predictive factor was successful in predicting RVF, alone or in combination due to limited number of patients and events. Large further investigations are needed to identify the predictors or scoring system in pediatric population.

Background: The aim of this study was to compare our experience of left ventricular assist device implantation via minimally invasive left thoracotomy with off-pump versus on-pump technique. Methods: Between June 2013 and April 2020, nine patients (8 males, 1 female; mean age: 47±11.9 years; range, 30 to 61 years) who underwent off-pump left ventricular assist device implantation and nine patients (8 males, 1 female; mean age: 47±11.4 years; range, 29 to 60 years) who underwent on-pump minimally invasive left thoracotomy were retrospectively analyzed. Postoperative outcomes and mid-term results of both groups were evaluated. Results: Outflow graft was anastomosed to the ascending aorta with J-sternotomy in all patients. The median duration of intubation and intensive care unit stay were one (IQR: 1.5) day and eight (IQR: 6.5) days in the off-pump group, respectively and one (IQR: 0) day and seven (IQR: 7) days in the on-pump group, respectively. Intra-aortic balloon pump was needed during the weaning of cardiopulmonary bypass in one (11%) of the patients in both groups. Postoperative right ventricular failure was observed in two (22%) patients in the offpump group who were treated medically and recovered. There was no need for revision due to bleeding or postoperative extracorporeal membrane oxygenator implantation in either group. In the off-pump group, three patients underwent heart transplantation after median 854 (IQR: 960) days. Three patients died one month, two and four years after implantation. Three patients were still alive with left ventricular assist device and were being uneventfully followed for 365, 400, and 700 days after implantation. Conclusion: Off-pump technique is safe and feasible option for implantation of left ventricular assist device via minimally invasive left thoracotomy.
RESUMEN
INTRODUCTION: Ischemia due to microvascular dysfunction may be responsible for the heterogeneity of ventricular repolarization in coronary slow flow. To our knowledge, there is no study in which QT interval, Tp-Te interval, index of cardiac-electrophysiological balance (iCEB), and frontal QRS-T angle were evaluated together in patients with CSF. In this study, we examined for the first time the relationship between all these myocardial repolarization parameters and CSF. MATERIALS AND METHODS: The study group included 178 patients (99 female, mean age: 50.6 ± 8.6 years) with isolated CSF without stenotic lesions and with angiographically proven normal coronary arteries. The control group included 120 patients (71 female, mean age: 49.3 ± 9.4 years) with normal coronary angiography. QRS duration, QT interval, QTc interval, Tp-Te interval, Tp-Te/QT, Tp- Te/QTc, iCEB score, and frontal QRS-T angle were calculated from 12lead ECGs. RESULTS: There was no significant difference in demographic parameters between the two groups. Compared with the control group, patients with CSF had significantly longer QTmax duration, QT dispersion, Tp-Te interval, and higher iCEB score, wider frontal QRS-T angle. CONCLUSION: In our study, we found that many of the ventricular repolarization parameters were adversely affected in patients with CSF. Impaired parameters may be associated with the risk of malignant ventricular arrhythmias.

OBJECTIVE: Maintaining sinus rhythm is important in the management of atrial fibrillation (AF). After cardioversion, there is a significant probability of AF recurrence. There is limited research on the relationship between AF recurrence and ECG parameters. This study aimed to evaluate whether the frontal plane QRS-T angle (fQRS-T), a predictor of ventricular heterogeneity, could be used to predict AF recurrence following cardioversion. METHODS: The study was conducted as a retrospective observational study. Patients diagnosed with acute-onset AF for the first time were included in the study. All patients underwent an ECG after cardioversion, and ECG parameters were evaluated. The patients were separated into two groups based on the presence of AF recurrence during hospitalization after cardioversion. The relationship between the fQRS-T and AF recurrence was also examined. RESULTS: A total of 162 patients, comprising 68 women (41.9%) and 94 men (58.1%) with an average age of 59.4±6.5 years, were enrolled in the research. Based on the patient monitoring device findings, patients were separated into two groups: non-recurrent AF (n=118) and recurrent AF (n=44). P-wave duration was significantly longer in the recurrence group (p=0.009). The recurrence group's mean fQRS-T was significantly higher (p<0.001). AF recurrence was substantially higher in patients with fQRS-T >90 ° compared to those with fQRS-T ≤90 ° (56.1% vs. 14.2%, p <0.001). Increased fQRS-T>93.7 ° indicated AF recurrence with 78.3% sensitivity and 83.4% specificity (AUC {area under curve}:0.748, p < 0.001). In multivariate analysis, fQRS-T was revealed to be an early indicator of recurrent AF (OR: 1.882, 95%CI: 1.358-2.881, p<0.001). CONCLUSION: The fQRS-T, an easily determinable parameter from automatic identification ECG recordings, may be useful for predicting the early return of AF after successful cardioversion.
RESUMEN
OBJECTIVE: The frontal QRS-T angle (fQRS-T) is associated with myocardial ischemia and ventricular arrhythmias. On the other hand, acute pulmonary embolism (APE) is a major risk factor for cardiac adverse events. This research aimed to determine whether the fQRS-T, a marker of ventricular heterogeneity, can be used to predict successful thrombolytic therapy in patients with APE. METHODS: This was a retrospective observational study. Patients diagnosed with APE and hospitalized in the intensive care unit between 2020 and 2022 were included in the research. A total of 136 individuals with APEs were enrolled in this research. The patients were divided into two groups: thrombolytic-treated (n=64) and non-treated (moderate to severe risk, n=72). An ECG was conducted for each patient, and echocardiography was performed. RESULTS: The mean age of the thrombolytic group was 58.2±17.6 years, with 35 females (55.1% of the group) and 29 males (44.9%). The non-thrombolytic group had a mean age of 63.1±16.2, with 41 females (56.5%) and 31 males (43.5%). Respiratory rate, heart rate, and fQRS-T were higher in the thrombolytic group, and oxygen saturation ratio and systolic and diastolic blood pressure were higher in the non-thrombolytic group (p=0.006, p<0.001, p=0.021; p<0.001, p=0.015, p<0.001, respectively). In the thrombolytic therapy group, comparing pre- and post-treatment ECG data revealed a statistically significant change in the fQRS-T value (p=0.019). CONCLUSION: The fQRS-T may provide important clues for the successful treatment of APEs.
RESUMEN
OBJECTIVE: Coronary slow flow (CSF) is linked to myocardial ischemia, malignant arrhythmias, and cardiovascular mortality. On the other hand, hypertension (HTN) is an important risk factor for vascular disorders. There is limited research on the relationship between CSF and HTN. This study aimed to investigate TIMI frame count (TFC), which is an indicator of CSF, in dipper and non-dipper hypertensive individuals with normal coronary arteries. METHODS: The study was conducted as a retrospective observational study. Patients diagnosed with CSF and dipper or non-dipper hypertension were included in this study. Blood tests were routinely conducted for all patients. ECG was conducted for each patient, and echocardiography was performed. Coronary artery images were obtained in the CAG laboratory. Blood pressure (BP) measurements were obtained from the ambulatory Holter records. The patients were separated into two groups based on ambulatory Holter monitoring. The relationship between CSF and HTN was also examined. RESULTS: A total of 71 patients, comprising 25 women (37.2%) and 46 men (62.8%) with an average age of 52.75±9.42 years, were enrolled in the research. Based on ambulatory BP, the individuals were separated into two groups: non-dipper (n=36) and dipper (n=35). The pulse rate was significantly higher in the non-dipper group (p<0.001). In terms of mean systolic and diastolic blood pressure, there were no substantial differences across the groups (p = 0.326 and p = 0.654, respectively). The daytime mean systolic and diastolic BP did not significantly differ across the groups (p = 0.842 and p = 0.421). The dipper group had substantially lower nighttime systolic and diastolic BP values (p <0.001). The LAD, Cx, and RCA TIMI frame scores were significantly lower in the dipper group (p<0.001). CONCLUSION: In this study, non-dipper patients had a greater CSF rate than dipper.
RESUMEN
BACKGROUND: A consensus has not yet been reached regarding which COVID-19 vaccine program should be applied in patients with ventricular assist device (VAD). Our aim was to assess the clinical outcome of inactivated, mRNA and heterologous vaccine program in patient with VAD. METHODS: In this retrospective and cross-sectional study; adult patients who underwent VAD implantation between January 2012 and September 2021 and received any vaccine that were used in Republic of Türkiye for COVID-19, were included. The patients were divided into three groups according to the type of vaccine; "inactivated," "mRNA" and "heterologous." Clinical outcomes were analyzed. RESULTS: Eighteen patients were in each group in the "inactivated," "mRNA" and "heterologous" groups. Mean age was 51.6 ± 12 years in "inactivated" group, 42.5 ± 15.5 years in "mRNA" group and 41.1 ± 15.4 years in "heterologous" group. There was no significant difference between the groups in age, gender, body surface area, body mass index and etiology (p > 0.05). After last dose of vaccines, the number of patients had COVID-19 positive test were three (16.7%), one (5.6%), and two (11.1%) in "inactivated," "mRNA" and "heterologous" groups, respectively. Pump thrombosis was seen in two patients in "mRNA" group and one patient in "heterologous" group. No pump thrombosis was seen in "inactivated" group. COVID-19-related death or intubation was not observed. CONCLUSION: All vaccine that used for COVID-19 are safe and effective in patients with VAD. In countries that give priority to inactivated vaccines, mRNA vaccines may then be made as boosters.

RESULTS: When the visual analog scale was compared between the groups, it was found to be significantly different (transfemoral artery: 2.7±1.6, traditional radial artery: 3.9±1.9, and distal radial artery: 4.9±2.1, respectively, p<0.001). When the patients were classified as mild, moderate, and severe based on the visual analog scale score, a significant difference was found between the groups in terms of body mass index, process time, access time, and number of punctures (p<0.001). Based on the receiver operating characteristic analysis, body mass index>29.8 kg/m2 predicted severe pain with 72.5% sensitivity and 73.2% specificity [(area under the curve: 0.770, 95%CI: 0.724-0.815, p<0.0001)]. CONCLUSION: In our study, we found that the femoral approach caused less access site pain and a high body mass index predicts severe pain.
RESUMEN
INTRODUCTION: Doxorubicin (DOX) is an anthracycline cytotoxic chemotherapeutic drug that is commonly used in cancer treatment. A major side effect limiting the clinical use of DOX is cardiotoxicity due to oxidative injury. Nigella sativa (NS) is an annual flowering plant with antioxidant properties. Its seeds contain several bioactive constituents such as saturated and unsaturated fatty acids, thymoquinone, dithymoquinone, thymohydroquinone, and thymol. In this study, we investigated the effect of NS extract on DOX-induced cardiotoxicity. METHODS: The experimental study animals consisted of 28 male Sprague Dawley rats weighing between 300 and 400 g. Four study groups each of seven rats were defined: controls; NS extract; DOX; and DOX+NS. Control and DOX rats received standard food, while each rat in the NS and DOX+NS groups also received 100 mg/kg NS extract orally. At day 28 of follow-up, rats in the DOX groups were administered a single 10 mg/kg intraperitoneal dose of DOX, while rats in the control and NS groups received a single 10 mg/kg dose of physiological saline solution. All animals were monitored for 35 days. On day 35, the rats were decapitated and serum and cardiac tissue samples were obtained. Troponin and NT-proBNP levels were measured in blood sera, while malondialdehyde (MDA), nitric oxide, total antioxidant capacity (TAC), and total oxidative stress (TOS) levels were quantified in sera and tissue samples. Histological alterations that were assessed in cardiac tissue included myocyte disarray, small vessel disease, myocyte hypertrophy, and fibrosis. RESULTS: The DOX group had significantly higher NT-proBNP, TOS, and MDA, with greater histopathological derangement. TAC was significantly elevated in the DOX+NS group, which also exhibited significantly lower troponin, TOS, and MDA, as well as significantly higher TAC compared to the DOX group. Histopathological examination showed that the significant structural derangement observed in DOX rats was markedly and significantly reduced in DOX+NS rats. CONCLUSION: Our results suggest that NS extract may prevent DOX-induced cardiotoxicity and thus represents a promising cardioprotective agent.
RESUMEN
OBJECTIVE: Staple line bleeding control (SLBC) after laparoscopic sleeve gastrectomy (LSG) is a serious problem. Cauterization alone is generally not preferred because of concerns about weakening the staple line. The aim of this study was to compare the suturing and monopolar cauterization methods for SLBC in LSG. METHODS: 212 patients were divided into two groups as cautery and suture groups. Demographic characteristics, intraoperative, and post-operative results were analyzed. RESULTS: Post-operative complications were seen in seven patients, four of them staple line bleeding (three patients were in the cautery group and one patient was in the suture group), and three of them leakage (all patients were in the suture group) from the staple line. There was no significant difference between the groups in terms of staple line bleeding (p = 0.35), staple line leakage (p = 0.09), blood loss (p = 0.12), intraoperative complications (p = 0.16), post-operative hemoglobin decrease (p = 0.63), and length of hospital stay (p = 0.35), but the operation time was longer in the suture group. CONCLUSION: This is the first study in literature comparing monopolar cauterization with another technique. Monopolar cauterization can be used for SLBC in LSG. It is a safe and efficient method as well as inexpensive.
OBJETIVO: El control del sangrado de la línea de grapas (SLBC) después de la gastrectomía en manga laparoscópica(LSG) es un problema grave. Generalmente, no se prefiere la cauterización sola debido a preocupaciones sobre el debilitamiento de la línea de grapas. El objetivo de este estudio fue comparar los métodos de sutura y cauterización monopolar para SLBC en LSG. MÉTODOS: 212 pacientes fueron divididos en 2 grupos de cauterización y sutura. Se analizaron las características demográficas, los resultados intraoperatorios y posoperatorios. RESULTADOS: Se observaron complicaciones posoperatorias en siete pacientes, cuatro de ellos sangrado en la línea de grapas (tres pacientes estaban en el grupo de cauterización, un paciente en el grupo de sutura) y tres de ellos fuga (todos los pacientes estaban en el grupo de sutura) del línea de grapas. No hubo diferencia significativa entre los grupos en términos de sangrado de la línea de grapas (p = 0.35), fuga dela línea de grapas (p = 0.09), pérdida de sangre (p = 0.12), complicaciones intraoperatorias (p = 0.16), disminución de hemoglobina postoperatoria (p = 0.63), duración dela estancia hospitalaria (p = 0.35), pero el tiempo de operación fue mayor en el grupo de sutura. CONCLUSIÓN: Este es el primer estudio que compara la cauterización monopolar con otra técnica. La cauterización monopolar se puede utilizar para SLBC en LSG. Es un método seguro, eficaz y económico.
