Abstract
Cardiac tumors are very rare in children, and echocardiography is very important in their detection. The clinical presentation can vary greatly depending on arrhythmia or obstruction. One of the most important factors determining the surgical approach is the clinical process. In this case report, we report the surgical treatment of a rhabdomyoma that caused refractory ventricular tachycardia.

Abstract
OBJECTIVE Fasciola hepatica and Fasciola gigantica are liver trematodes that cause fascioliasis in humans and animals. In Turkey, the medical importance of fascioliasis has been increasing in humans, and it continues to cause great economic loss in the field of animal husbandry. Therefore, it is important to diagnose fascioliasis quickly and reliably. The aim of this study is to show that the ELISA test is a reliable and specific method for diagnosing fascioliasis both in the early stage and in the acute stage. PATIENTS AND METHODS In this study, 640 individuals aged 7-75 years who showed one or more symptoms of fascioliasis, such as abdominal pain, fever, weight loss, weakness, fatigue, headache, sweating, nausea, vomiting, allergic urticaria, liver mass, hypereosinophilia, or liver enzyme elevation, were recruited from the Dicle University Research and Application Hospital in southeastern Turkey. Serum and fecal samples were taken from them to investigate if the Fasciola hepatica IgG antibody was present in the serum and if eggs were present in the feces. To detect the IgG antibodies, an enzyme-linked immunosorbent assay (ELISA) kit was used. The stool samples were analyzed for three consecutive days in mini Parasep fecal parasite concentrator tubes using the native-lugol and sedimentation methods. Abdominal ultrasonography and computed tomography were performed in all the patients. RESULTS Among the subjects of this study, 90 (14%) were positive for fascioliasis, of whom 85 (94.4%) were adults and 5 (5.5%), children; 73 (81.1%) were women and 17 (18.8%), men; 57 (63.3%) lived in the rural areas and 33 (36.6%), in the city center; 90 (14%) were positive for Fasciola hepatica IgG antibodies; (20%) had helminth eggs in their stools; and 85 (94.4%) had a history of eating watercress. CONCLUSIONS According to the epidemiological classification for fascioliasis by Mas-Coma, the Dicle Basin, which is the setting of this study, is indeed a hyperendemic region. Thus, ELISA is a reliable and specific method of diagnosing fascioliasis, both in the early phase and in the acute phase, when the eggs are no longer seen in the stool.

Abstract
Background This study aims to investigate the incidence and risk factors for chylothorax and to evaluate the effect of chylothorax on the early postoperative outcomes following congenital cardiac surgery. Methods A total of 1,053 patients (606 males, 447 females; median age: 12 months; range, 3 days to 48 years) who underwent surgery for congenital heart disease at our institute between January 2018 and December 2019 were retrospectively analyzed. Patients with chylothorax were identified and the data of this cohort was compared with the entire study population. Following the diagnosis of chylothorax, a standardized management protocol was applied to all patients. Results Of 1,053 patients operated, 78 (7.4%) were diagnosed with chylothorax. In the univariate analysis, younger age, peritoneal dialysis, preoperative need for mechanical ventilation, surgical complexity, delayed sternal closure, high vasoactive inotrope score in the first 24 h after operation, residual or additional cardiac lesions which required reoperations were found to be the risk factors for chylothorax (p<0.05). In the multivariate analysis, the correlation persisted with only younger age, infections, and peritoneal dialysis requirement (p<0.05). In the chylothorax group, ventilation times were longer, and re-intubation and infection rates were higher (p<0.05). Although the length of intensive care unit and hospital stay was significantly longer in this patient group, there was no significant association between the development of chylothorax and in-hospital mortality (p>0.05). Conclusion Chylothorax following congenital cardiac surgery is a significant problem which prolongs the length of hospital stay and increases the infection rates. Complex cardiac pathologies which require surgery at early ages and re-operations are risk factors for chylothorax. Although there is no consensus on the most optimal therapeutic strategy, standardizing the management protocol may improve the results.

Abstract
BACKGROUND We aimed to compare the results of two surgical methods for the treatment of congenital supravalvular aortic stenosis. METHODS From May 2004 to January 2020, 29 patients underwent surgical repair for supravalvular aportic stenosis in a single centre. The perioperative evaluation of the patients was retrospectively reviewed. RESULTS Fifteen (51.7%) and 14 (48.2%) patients were treated with the Doty and the McGoon methods, respectively. The median age of our cohort was 4.5 (3.0-9.9) years. Ten (34.5%) patients had Williams-Beuren syndrome, and pulmonary stenosis was observed in 12 (41.3%) patients. The median follow-up time was 2.5 (0.7-7.3) years. On follow-up, five patients had residual stenosis with the McGoon technique and one with the Doty technique (p = 0.05). One patient died early in the post-operative period in the Doty group, and three patients were re-operated on due to restenosis in the McGoon group. Freedom from re-operation in the Doty group at 1, 3, 5, and 10 years was 100%. In the McGoon group, freedom from re-operation rates at the 1-, 3-, and 7-year follow-up were 100, 88.9, and 44.4%, respectively (p = 0.08). CONCLUSION Our results with both surgical techniques suggest that supravalvular aortic stenosis can be treated with good results. The Doty method provided better relief for the supravalvular aortic segment, considering the residual stenosis and the re-operation rates.

Abstract
INTRODUCTION AND OBJECTIVE There are various management options for newborns with single ventricle physiology, ventriculoarterial discordance and subaortic stenosis, classically involving the early pulmonary banding and aortic arch repair, the restricted bulboventriculer foramen enlargement or the Norwood and the Damus-Kaye-Stansel procedures. The aim of this study is to evaluate our preferred technique and comment on the midterm results of our clinical experience with palliative arterial switch operation (pASO) for a certain subset of patients. METHOD We hereby retrospectively evaluate the charts of patients who went through pASO, as initial palliation through Fontan pathway, starting from 2014 till today. RESULTS Ten patients underwent an initial palliative arterial switch procedure. Eight of 10 patients survived the operation and discharged. Seven of 10 patients completed Stage II and 1 patient reached the Fontan completion stage and the other six of ten (6/10) patients are doing well and waiting for the next stage of palliation. There are two mortalities in the series (2/10) and one patient lost to follow-up (1/10). CONCLUSION In our opinion, the pASO can be considered as an alternative palliation option for patients with single ventricle physiology, transposition of the great arteries and systemic outflow tract obstruction despite longer cross clamp times compared to other methods, but It not only preserves systolic and diastolic ventricular function, but also provides a superior anatomic arrangement for following stages.

Abstract
OBJECTIVE This study aims to present the midterm outcomes of surgical correction of the anomalous left coronary artery from the pulmonary artery (ALCAPA) with a focus on mitral regurgitation (MR). METHODS Medical records of 36 ALCAPA patients who underwent surgery in a single center were retrospectively reviewed. RESULTS There were one (2.7%) neonate, 19 (52.7%) infants, 15 (41.6%) children, and 1 (2.7%) adult patient operated. Coronary reimplantation, tube reconstruction, and coronary artery bypass surgery techniques were performed in 29 (80.5%), 6 (16.6%), and 1 (2.7%) patient, respectively. Sixteen (44.4%) patients had a low ejection fraction and 13 (36.1%) patients had at least moderate MR preoperatively. None of our patients underwent a concomitant mitral surgery during the initial repair. Three and two patients died in the early and late postoperative period, respectively. Two patients underwent reoperation due to MR and pulmonary stenosis, separately. Preoperative MR was the only factor associated with at least moderate MR at the final follow-up (p < .01) and the presence of preoperative moderate or over-moderate MR estimated at least moderate MR at the final follow-up with 100% sensitivity and 80% specificity. CONCLUSION Although the mitral valve was not repaired in the first operation, the reoperation rate is low. However, a moderate or higher preoperative MR predicted MR at the last follow-up. Performing annuloplasty in such patients can be a strategy to be researched.

Abstract
Background The aim of this study is to investigate the effect of COVID‐19 outbreak on congenital cardiac surgery practice in a single center. Methods The first case of COVID‐19 in our country was seen on March 11th, 2020. The patients operated between March 11th, 2019‐and March 10th, 2020 were taken as the pre‐COVID group, and those operated between March 11th and May 11th, 2020 were taken as the COVID group. The data was retrospectively collected, and the two periods were compared. Results Monthly average number of cases which was 52 patients/month (626 patients in 12 months) before COVID decreased to 35 patients/month (70 patients in 2 months) during COVID periods (P < .01). During the pre‐COVID period the median postoperative length of hospital stay was 3 (IQR: 1‐5) days. During the COVID period, this decreased to 1 (IQR: 1‐3) day (P < .01). During the pre‐COVID period, the hospital expenses of 17% (8/47) of the foreign nationals were covered by their homeland. The remaining 83% (39/47) were paid from the asylum seekers’ fund. The proportion of foreign nationals operated significantly decreased during the COVID period ([7%; 47/632 vs 1%; 1/70]; P = .04). No significant difference was observed in terms of STAT mortality scores and categories and postoperative results of the operations performed between the two periods. Conclusions Congenital cardiac surgery practice can be safely maintained with restricted case volume during the pandemic period. It is alarming that patients in the deprived areas cannot access pediatric cardiac surgery and possibly other health services because of closure of the borders between countries.

Abstract
OBJECTIVES This study aims to compare the early- and long-term outcomes of patients who undergo owl's eye pulmonary artery (PA) reconstruction to those of patients who undergo conventional PA reconstruction. METHODS From January 2016 to January 2017, 64 consecutive patients underwent an arterial switch operation. The patients were divided into 2 groups in terms of neo-PA reconstruction method: 30 patients who underwent neo-PA reconstruction by owl's eye technique were defined as group 1 and 34 patients who underwent neo-PA reconstruction by the conventional approach were defined as group 2. In the final model, after propensity matching, 23 patients from each group with similar propensity scores were included in the study. RESULTS There was no significant difference between the groups regarding patient characteristics and operative findings. In the early period, the duration of intensive care unit and hospital stays and the rate of mild neo-pulmonary stenosis (neo-PS) were significantly higher in the owl's eye group (P = 0.04, 0.04 and 0.03). In the late period, the rate of severe neo-PS and reintervention was significantly higher in the owl's eye group (P = 0.02 and 0.04). Furthermore, the rates of 3-year freedom from pulmonary reintervention and freedom from moderate-severe neo-PS were significantly lower in group 1 (P = 0.04). In addition, the owl's eye reconstruction was the only factor independently related to moderate-severe neo-PS in the long term (hazard ratios = 11.2, P = 0.02). CONCLUSIONS We have abandoned the owl's eye method for neo-PA reconstruction of the neo-PA because of serious complications. According to our series and the literature, reconstruction of the neo-PA with an oversized, pantaloon-shaped fresh autologous pericardial patch is still superior to the other techniques.

Abstract
Objective To compare the early and long-term results of patients in whom was performed modified closed coronary transfer with the results of patients in whom was performed trap-door transfer techniques by utilizing propensity-matching analysis to provide optimal identical patient matching for the groups. Methods From August 2015 to December 2017, 127 consecutive patients underwent arterial switch operation due to simple and complex transposition of the great arteries, with or without additional arch and complex coronary pattern, by a single surgical team included into the study. Of these, in 70 patients it was performed modified closed coronary transfer technique and in 57 patients it was performed trap-door style coronary transfer technique. The patients were divided into two groups in terms of coronary transfer method. In the final model, after propensity matching, 47 patients from each group having similar propensity score were included into the study. Results There was no significant difference between the groups regarding patient characteristics. Cross-clamp time and operation time were significantly lower in the modified technique group compared with the other group (P=0.03 and P=0.05, respectively). When compared the early and late postoperative outcomes, there was no significant difference between the groups. Postoperative echocardiographic findings were mostly similar between the groups. Conclusion The patients in whom was performed our modified technique demonstrate overall good outcomes and the current technique ensures shorter arterial cross-clamp and operation times. It may be an alternative method to the trap-door technique for the coronary transfer during the arterial switch operation.

Abstract
An eight-year-old boy with tricuspid atresia was found to have atretic coronary sinus ostium during cardiac catheterization. Single-stage extracardiac fenestrated Fontan operation was performed with surgical unroofing of the coronary sinus into the left atrium to avoid the risk of cardiac congestion.

Abstract
Background: The aim of this study was to evaluate the predictability of postoperative pulmonary artery pressure (PAP) using intraoperative flow study in patients undergoing bidirectional Glenn operation. Methods: Patients who underwent Glenn operation under cardiopulmonary bypass (CPB) were included in the study. During the operation, after the completion of additional procedures under CPB, an intraoperative flow study was performed prior to Glenn anastomosis. After the completion of bidirectional Glenn, the patient was separated from the CPB and PAP was measured. The relationship between this pressure and flow study measurement was analyzed. Results: Nine patients who underwent bidirectional Glenn operation with additional procedures under CPB between July 2018 and January 2019 were included in the study. The median PAP was 9 mm Hg (interquartile range [IQR]: 7-10 mm Hg) in the flow study and 10 mm Hg (IQR: 8-11 mm Hg) after CPB, and the median difference between these pressures was 1 mm Hg (IQR: 1-3 mm Hg). There was a strong correlation between these two measurements ( r = 0.732; P = .025). Conclusion: The results of this study show that PAP after the Glenn procedure can be estimated using an intraoperative flow study. We believe that this method may be useful in intraoperative decision-making for Glenn operation in single ventricular patients who require extensive pulmonary artery (PA) reconstruction due to limited PA development, branch PA stenosis, or nonconfluent PAs. Also, this method can be used as a sort of intraoperative pulmonary resistance reversibility study in patients with high preoperative pulmonary vascular resistance due to surgically correctable pulmonary venous hypertension.

Abstract
BACKGROUND/AIM The data on the Nikaidoh procedure is limited in the literature. This study presents our experiential findings with aortic translocation (Nikaidoh) procedure and its modifications. METHODS We retrospectively reviewed the data of all the patients who underwent aortic translocation in our institution. RESULTS Between September 2014 and November 2018, eight patients underwent aortic translocation surgery. The median age was 3.2 years (14 months and 9 years). The diagnosis was transposition of the great arteries (TGA), ventricular septal defect (VSD), and left ventricular outflow tract obstruction (LVOTO) in five patients (63%); double-outlet right ventricle (DORV), VSD, and LVOTO in two patients (25%) and DORV and remote VSD in one patient (12%). Additionally, two patients had tricuspid straddling. In terms of surgical procedures, six patients underwent standard Nikaidoh procedures, while one patient underwent double root translocation and one patient underwent a half-turned truncal switch operation. Hospital mortality was recorded for one patient (12.5%). Median intensive care and hospital stay duration was 3 days (interquartile range [IQR]: 2-5 days) and 11 days (IQR: 8-17 days). Median follow-up duration was 10 months (IQR: 10-24 months). One of the patients, who underwent standard Nikaidoh procedure, died in the late follow-up. CONCLUSIONS Aortic translocation procedure is an option for TGA, VSD, and LVOTO patients with a distal VSD or tricuspid straddling and DORV patients with a small VSD. Avoiding the use of a conduit through modifications, such as double root translocation and half-turned truncal switch operation, may decrease the risk of long-term recurrent interventions.

Abstract
BACKGROUND This study aimed to describe the learning curve of the extracardiac Fontan procedure in a single center and to analyze the changes in clinical applications and outcomes. METHODS A retrospective chart review of all extracardiac Fontan patients in a single tertiary care center was undertaken. Patients with a diagnosis of hypoplastic left heart syndrome and those who had undergone a lateral tunnel modification, intra/extracardiac Fontan, Kawashima procedure, or inferior vena cava-to-azygous vein connection were excluded from the analysis. RESULTS Between May 2004 and February 2018, data of 159 extracardiac Fontan patients were analyzed. The median age was 5.5 years (range 4.5-8.2 years). Based on a cumulative sum analysis, a hinge point was determined to divide the cohort into 2 phases. Phase 1 ( n = 70) represented the first learning phase and phase 2 ( n = 89) represented the later phase. Mortality decreased in phase 2 (2/89; 2%) compared to phase 1 (10/70; 14%; p = 0.004). Two (3%) patients had extracorporeal membrane oxygenation in phase 1, and 5 (6%) in phase 2 ( p = 0.47). More patients in phase 2 underwent a prior bidirectional Glenn procedure (83/89 vs. 57/70; p = 0.02), fenestration (80/89 vs. 9/70; p < 0.001), and pulmonary artery reconstruction (37/89 vs. 2/70; p < 001). CONCLUSIONS This study shows that increased use of extracorporeal membrane oxygenation, strict implementation of the three-stage management plan, routine fenestration, and a low threshold for pulmonary artery reconstruction may be associated with decreased mortality in the extracardiac Fontan procedure.

Abstract
BACKGROUND The effects of ageing on the histopathological changes of tem-poromandibular joint (TMJ) and the existence and age related alterations of immunochemical expressions of type I collagen and matrix metalloproteinase-2 (MMP-2) proteins was aimed to be displayed. MATERIALS AND METHODS In this study, 14 Balb/C type white mice (50- -80 g) were included. Groups were organised as group 1 - 2-month-old young animals (n = 7) and group 2 - 18-month-old old animals (n = 7). Of the paraffin embedded tissues 4-5 μm thick sections were taken and immunohisto-chemical stainings of haematoxylin-eosin, type-1 collagen and MMP-2 were performed. RESULTS Collagen bundles showed sagittal and oblique localisations in the young mice, which were comprised of compact collagen bundle layers positioned alterna-tely. While collagen bundle fragmentation was observed in the disks of old mice, some disk regions showed ruptures. In the old mice a decrease in blood vessels, structural impairments and dilatation in arterioles and venules were detected. In the TMJ tissues of the young mice type I collagen and MMP-2 expressions were increased, while they were decreased in old mice. In the MMP-2 H-score evaluation young mice showed significant increase compared to the old mice. CONCLUSIONS Occurrence of degenerations in the collagen structure of TMJ and decimation in the matrix metalloproteases were observed with age. (Folia Morphol 2018; 77, 2: 329-334).
