    Comparison of Surgical Techniques Used in Ventricular Septal Defect Closure
    (2023) Celik, Mehmet; Aygun, Fatih; Gunaydin, Asim Cagri; Gokdemir, Mahmut; Cindik, Nimet; 0000-0002-5018-0068; 36592069; AAT-2031-2021
    Introduction: We compared transatrial closure, tricuspid valve septal detachment, and tricuspid valve chordal detachment techniques for ventricular septal defect (VSD) closure. Methods: Patients who had VSD closure with three different techniques in our clinic between September 2016 and December 2020 were retrospectively reviewed. A total of 117 patients were included in the study. The patients were divided into three groups: group 1, classical transatrial closure; group 2, closure with tricuspid valve septal detachment; and group 3, closure with tricuspid valve chordal detachment. The groups were evaluated by serial transthoracic echocardiography (preoperative, postoperative 1st day, postoperative 1st month). Cardiac rhythm checks and recordings were performed. Results: No residual VSD was observed in early or late periods in any of the groups whose VSD closure was performed with the three different techniques. No severe tricuspid regurgitation (TR) was detected during the early and late postoperative periods of all operating procedures. When the groups were compared in terms of early/late TR after the operation (without TR+trace amount of TR and mild TR+moderate TR were compared), no statistically significant difference was found (P>0,05; P=0,969 and P>0,05; P=0,502). Conclusion: In this study, we found no statistically significant difference between three VSD closure techniques in terms of early TR, late TR, residual VSD, and permanent atrioventricular complete block during postoperative period. We hope that our results will be supported by the results of researches that are being made about this subject in large series.

    Risk Factors for and Incidence of Hospital-Acquired Infections After Cardiac Surgery in Children with Congenital Heart Disease: A Single Center Experience
    (2023) Cindik, Nimet; Gokdemir, Mahmut; Celik, Mehmet; Gunaydin, Asim Cagri; 0000-0001-8544-0125; 37853968; AAD-9425-2021
    Background. The epidemiology of hospital-acquired infections (HAIs) has been less well studied in critically ill children in pediatric cardiothoracic intensive care units. This study aimed to investigate independent risk factors for and incidence of HAIs after cardiac surgery in children with congenital heart disease (CHD).Methods. Our study included 574 patients who underwent congenital heart surgery and were followed up in the cardiothoracic intensive care unit between September 2016 and December 2020. All patients were divided into four groups according to age: 0-1 months, 1-6 months, 6-12 months, and 1-18 years, and into two subgroups according to HAI development.Results. The patients' median age and weight at surgery were 3.28 (interquartile range [IQR]): 0.43-8.1) months and 4.34 (IQR: 4.34-6.69) kg, respectively. HAIs and infection-related deaths were observed in 223 and 21 patients, respectively. Age at surgery, weight at surgery, concomitant syndromes and immunodeficiency status, presence of cyanotic heart disease, intubation, and use of antibiotics during hospitalization were statistically significant between the two groups with and without infection (p<0.05). In logistic regression analysis, surgical weight <5 kg (odds ratio [OR]: 2.55; 95% confidence interval [CI]: 1.56-4.17; p <0.001), preoperative mechanical ventilation (OR: 2.0; 95% CI: 1.26-3.12; p=0.003), complexity of cardiac surgery according to the risk-adjusted congenital heart surgery classification score 3 (OR: 3.13; 95% CI: 1.24-7.92; p=0.016), presence of an concomitant syndrome (OR: 1.56; 95% CI: 1.02-2.88; p=0.040), age (OR: 1.01; 95% CI: 1.01-1.04; p=0.044) were independent risk factors for HAIs after cardiac surgery in children with CHD.Conclusions. In this study, younger age, presence of an associated syndrome, preoperative mechanical ventilation, and weight less than 5 kg were found to be independent risk factors for HAI after cardiac surgery in children with CHD.
