Item Evaluation of acute kidney injury after surgery for congenital heart disease in neonates: a tertiary hospital experience(2022) Oktener Anuk, Ezgi; Erdogan, Ilkay; Ozkan, Murat; Baskin, Esra; Varan, Birgul; Tokel, Kursad N.; 0000-0001-6887-3033; 0000-0003-3991-8479; 35382696; ABB-2220-2021Purpose of the article Acute kidney injury (AKI) after cardiac surgery in children with congenital heart disease (CHD) is a serious complication closely associated with high morbidity and mortality. Despite numerous studies on AKI in children, most studies have excluded neonates. We sought to characterize AKI associated with cardiac surgery in neonates, determine its incidence, perioperative and postoperative risk factors, and short-term results. Materials and methods This retrospective study included 177 neonates who were operated on for CHD in our hospital between January 2015 and December 2019. Data of the patients were analyzed according to nKDIGO (neonatal Kidney Disease Improving Global Outcomes) and nRIFLE (neonatal Risk, Injury, Failure, Loss of function, End-stage kidney disease) criteria for evaluating AKI retrospectively. Data of groups with and without AKI were analyzed. Results The average age of 177 neonates were 8.2 +/- 6.1 (1-28) days. Twenty-two (12.4%) neonates had CS-AKI defined according to nKDIGO criteria. Four (2.3%) neonates reached nKDIGO stage I, 1 (0.6%) reached stage II, 17 (9.6%) reached stage III. Thirty-eight (21.5%) neonates had CS-AKI defined according to nRIFLE criteria. Twenty-four (13.6%) neonates reached nRIFLE stage risk(R), 6 (3.4%) reached stage injury(I), 8 (4.5%) reached stage failure (F). The incidence of cardiac surgery-associated acute kidney injury (CS-AKI) in neonates was 12.5% and 21.5% for nKDIGO and nRIFLE, respectively. The percentage difference between nKDIGO and nRIFLE for AKI assessment was due to the criteria for nRIFLE stage risk(R) urine output < 1.5 mL/kg/h for 24 h. In both classifications, the duration of cardiopulmonary bypass, operation, inotropic treatment, and mechanical ventilation, length of intensive care unit (ICU), and hospital stay were significantly higher in the AKI group than those without AKI group (p<.05). The mortality rate in the groups with AKI was found to be significantly higher (p<.05) than in the groups without AKI. In Kappa analysis, when two classifications were compared according to AKI stages, a significant agreement was found between nKDIGO and nRIFLE classifications (p<.05) (Kappa: 0.299). Conclusion AKI and mortality rates were similar between groups according to the nKDIGO and nRIFLE criteria. For early prediction of AKI and adverse outcomes, diagnostic reference intervals might be specified in more detail in neonates undergoing cardiac surgery for CHD.Item Neurologic Complications After Pediatric Heart Transplant: A Single-Center Experience(2022) Orgun, Ali; Erdogan, Ilkay; Varan, Birgul; Sezer, Taner; Tokel, N. Kursad; Ozkan, Murat; Sezgin, Atilla; 33797352Objectives: Neurologic complications that can lead to serious mortality and morbidity in pediatric heart transplant recipients have been reported to range from 23.6% to 45%. In this study, the frequency, time, cause, and characteristics of neurologic complications in pediatric heart transplant recipients were evaluated. Materials and Methods: We retrospectively reviewed data of 37 pediatric heart transplant recipients aged <18 years who were seen at our hospital between 2007 and 2017. Medical records were reviewed to identify neurologic complications. Clinical features were compared between pediatric heart transplant patients with and without neurologic complications. Results: The rate of posttransplant neurologic complications in pediatric heart transplant was 27% (10/37). Median age of patients with neurologic complications was 12 years (range, 11-18 years). Median time for neurologic complications was 3 days (range, 2-46 days). Primary diagnoses of these 10 recipients were dilated cardiomyopathy (n = 7) and restrictive cardiomyopathy (n = 3). There were no significant differences between recipients with and without neurologic complications (P>.05). The etiologies of neurologic complications were posterior reversible encephalopathy syndrome in 3 patients (8.1%), stroke in 2 patients (5.4%), peripheral neuropathy in 2 patients (5.4%), hypertensive encephalopathy in 1 patient (2.7%), and drug encephalopathy in 1 patient (2.7%). Conclusions: Neurologic complications may lead to serious mortality and morbidity in pediatric heart transplant patients. Seizures, posterior reversible encephalopathy syndrome, stroke, peripheral neuropathy, transient ischemic attack, and cerebral infections are the most common neurologic complications, which are seen in the perioperative period in particular. Careful follow-up of pediatric heart transplant patients, with detection and early treatment of neurologic findings, will contribute to lower rates of sequelae. To our knowledge, this is the largest study to show a detailed experience of neurologic complications in pediatric heart transplant patients from a single center in Turkey.Item Results of Balloon and Surgical Valvuloplasty in Congenital Aortic Valve Stenosis: A 19-Year, Single-Center, Retrospective Study(2021) Yakut, Kahraman; Varan, Birgul; Tokel, Niyazi Kursad; Erdogan, Ilkay; Ozkan, Murat; 0000-0002-6719-8563; 0000-0001-6887-3033; 34104509; ABB-1767-2021; ABB-2220-2021Background: This study aims to compare the success, complications, and long-term outcomes of aortic balloon valvuloplasty and surgical aortic valvuloplasty in pediatric patients with congenital aortic valve stenosis. Methods: Between March 2000 and October 2019, a total of 267 procedures, including 238 balloon valvuloplasties and 29 surgical valvuloplasties, in 198 children (135 males, 63 females; mean age: 57.4 +/- 62.6 months; range, 0.03 to 219 months) were retrospectively analyzed. The hospital records, echocardiographic images, catheterization data, angiography images, and operative data were reviewed. Results: Aortic regurgitation was mild in 73 patients before balloon valvuloplasty, and none of the patients had moderate-to-severe aortic regurgitation. Compared to surgical valvuloplasty, the rate of increase in the aortic regurgitation after balloon valvuloplasty was significantly higher (p=0.012). The patients who underwent balloon valvuloplasty did not need reintervention for a mean period of 46 +/- 45.6 months, whereas this period was significantly longer in those who underwent surgical valvuloplasty (mean 80.5 +/- 53.9 months) (p=0.018). The overall failure rate was 8%. Moderate-to-severe aortic regurgitation was the most important complication developing due to balloon valvuloplasty in the early period (13%). All surgical valvuloplasties were successful. The mean length of hospitalization after balloon valvuloplasty was significantly shorter than surgical valvuloplasty (p=0.026). During follow-up, a total of 168 patients continued their follow-up, and a reinterventional or surgical intervention was not needed in 78 patients (47%). Conclusion: Aortic balloon valvuloplasty can be repeated safely and helps to eliminate aortic valve stenosis without needing sternotomy. Surgical valvuloplasty can be successfully performed in patients in whom the expected benefit from aortic balloon valvuloplasty is not achieved.Item Restrictive cardiomyopathy with ring chromosome 6 anomaly in a child(2021) Erdogan, Ilkay; 34622791; CAE-9097-2022Item Complete Fetal Atrioventricular Block Associated with Maternal Autoinflammatory Diseases: Case Report and Literature Review(2020) Tugcu, Ali Ulas; Ince, Deniz Anuk; Esin, Sertac; Turan, Ozden; Erdogan, Ilkay; Ecevit, Ayse; 0000-0002-2232-8117; 0000-0002-7707-1881; 0000-0001-9577-4946; 0000-0002-4369-2110; 31903011; AAJ-4616-2021; AAJ-2333-2021; AAJ-2305-2021; AAI-8810-2021; I-6746-2016
