Background The aim of this study was to investigate whether routine complete blood count parameters such as the mean platelet volume, red cell distribution width, white blood cell and platelet counts, and novel inflammatory biomarkers such as platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio could be used as the predictors of acute deep vein thrombosis. Methods This retrospective study included a total of 68 patients (29 males, 39 females; mean age 55.2±1.6 years; range, 22 to 80 years) with acute lower extremity deep vein thrombosis and 34 healthy controls (15 males, 19 females; mean age 52.8±2.5 years; range, 21 to 77 years) without acute lower extremity deep vein thrombosis between March 2016 and August 2018. Demographic and clinical characteristics of the participant and laboratory data including complete blood count parameters were recorded. Univariate and multivariate analyses were used to identify significant predictors of deep vein thrombosis. Results Demographic and clinical characteristics were similar between the groups. According to the univariate analysis, platelet count and red cell distribution width were found to be significantly higher in the patient group compared to the control group. However, the red cell distribution width was not considered a significant predictor of acute deep vein thrombosis. According to the multivariate logistic regression analysis, the platelet-to-lymphocyte ratio and platelet count were significant predictors of acute deep vein thrombosis. Conclusion Our study results show that the platelet-tolymphocyte ratio may be a useful biomarker to support the diagnosis of acute deep vein thrombosis.

Methods Between January 2018 and October 2018, a total of 51 patients (43 males, 8 females; mean age 61.8±8.7 years; range, 38 to 78 years) who underwent isolated on-pump coronary artery bypass grafting were included. Thiol-disulfide homeostasis parameters were studied in the preoperative period (T1), 30 min after the removal of cross-clamp (T2), and postoperative sixth h (T3). Hemodynamic parameters such as atrial fibrillation and inotropic support requirement of the patients were evaluated in the postoperative period. Results There were significant differences in the measured thiol-disulfide homeostasis parameters at different time points of surgery (p less then 0.001). Binary logistic regression analysis showed that T2-disulfide/native thiol ratio was an independent predictor of the development of postoperative atrial fibrillation (p=0.042). There were positive and significant correlations between the T2-disulfide levels and cross-clamp time (r0.307, p=0.029). Conclusion Thiol-disulfide homeostasis in patients undergoing on-pump coronary artery bypass grafting changes toward to disulfide. Disulfide levels increase in parallel with prolonged ischemia time. Decreased native thiol and increased disulfide levels during ischemic period may be predictive of postoperative atrial fibrillation.

Methods Between March 2010 and February 2018, a total of 34 patients (8 males, 26 females; mean age 58.3 years; range, 34 to 78 years) who underwent robotic-assisted concomitant procedures during mitral valve surgery were retrospectively analyzed. Demographic characteristics of the patients, comorbidities, medical, and surgical histories, operative and laboratory results, electrocardiographic findings, postoperative intensive care unit and ward outcomes, and cardiac follow-up data were recorded. Atrial fibrillation-related medication use, stroke, or other thromboembolic events, and electrocardiographic reports in patients who underwent cryoablation were reviewed at three and 12 months after the operation. Results A total of 76 robotic-assisted concomitant procedures were performed during mitral valve repair (n=11) or replacement (n=23) in 34 patients. Concomitant procedures in addition to mitral valve operations can be performed with low complication rates in centers with experience of robotic surgery.

Methods Between December 2010 and December 2016, a total of 40 patients (25 males, 15 females; mean age 45±41 days; range, 2 days to 6 months) who underwent total anomalous pulmonary venous connection repair were retrospectively analyzed. Results Eighteen (45%) of the patients were supracardiac, seven (17.5%) were cardiac, eight (20%) were infracardiac, and seven (17.5%) were mixed-type anomaly. Twelve patients (30%) had obstruction of the pulmonary venous pathways. Hospital mortality was seen in three patients (7.5%). All of non-survivors received emergent surgery and the causes of death were sepsis and multiple organ failure. A total of 23 complications were seen in 20 patients (50%) mainly delayed sternal closure (n=11; 27.5%) and prolonged mechanical ventilation (n=6; 15%). mTOR inhibitor review The mean follow-up was 12.2±9.6 (range, 1 to 36) months in all patients, except one. Pulmonary vein stenosis developed in three patients (8.3%) after repair. All of them underwent sutureless repair. Conclusion Total anomalous pulmonary venous connection can be repaired with low mortality and morbidity rates and favorable mid-term outcomes. Close follow-up is necessary due to the risk of development of pulmonary vein stenosis. Sutureless repair may provide relief in such cases.

Methods Between June 2006 and August 2017, a total of 421 consecutive patients (266 males, 155 females; mean age 53.1±15.6 years; range, 5 to 89 years) who underwent mitral valve repair with or without concomitant cardiac procedures were retrospectively analyzed. All pre-, intra-, and postoperative data were collected. Echocardiographic examinations were performed at discharge and during follow-up. Kaplan-Meier analysis was used to estimate overall survival and from residual severe mitral regurgitation, endocarditis and reoperation-free survival rates. Results The mean follow-up was 58.9±35.1 months. Of the patients, 12 (2.8%) had previous cardiac operations. The most predominant pathology was degenerative disease in 265 patients (62.9%). Repair techniques included ring annuloplasty (n=366, 86.9%), artificial chordae implantation (n=185, 44%), and commissurotomy (n=38, 9%). Overall in-hospital mortality rate was 1.
