Abstract
PURPOSE 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.

Abstract
BACKGROUND AND OBJECTIVES In this study, we aimed to review the treatment options and long-term problems of patients who were diagnosed with coronary artery fistulae (CAF) in our institution. We also tried to determine the most appropriate time for treatment of this condition. METHOD From 2000 to 2018, the medical records of 56 patients (33 males and 23 females) who had CAF diagnoses were retrospectively reviewed. RESULTS The mean age of the patients at the time of diagnosis was 3.9 ± 4.6 years (range, 1 month to 18 years) and the mean duration of the follow-up period was 7.4 ± 4.5 years (range, 1 year to 17.5 years). The right coronary artery (RCA) was the most common origin site for CAF, the left main coronary artery (LMCA) was the second most common origin site whereas the left anterior descending coronary artery (LAD) was the third most common origin site. Catheter angiography showed that right ventricle (RV) was the site of termination for CAF in 23 patients (41.1%) while the CAF drained to the pulmonary artery in 16 patients (28.6%). Transcatheter intervention was performed in ten patients, while CAF were corrected surgically in five patients. Transcatheter intervention was initially attempted in two out of the five surgically-treated patients, but the procedure was unsuccessful. A vascular plug was deployed in six patients, a platinum coil was used in three patients, and a platinum coil with tissue adhesive was placed in one patient using a catheter. Early complications were seen in two patients during transcatheter intervention and in one patient during surgery. There were no instances of death or late complications in patients treated surgically or via transcatheter. CONCLUSIONS Coronary artery fistulae are usually asymptomatic, and medical therapy with long term follow up is the first line treatment. Fistulae that cause hemodynamically significant shunting, chamber enlargement, or visible symptoms should be closed at an early age. This study shows that transcatheter closure is a safe treatment option for CAF that may be performed with high success. Also, it should be known that surgery may be performed effectively with low rates of complications. Because complications can develop in treated and untreated patients of all ages, follow-up should occur during the patient`s lifetime.

Abstract
BACKGROUND AND OBJECTIVES Right ventricular failure is an important cause of mortality and morbidity after orthotopic heart transplantation (OHT). The right ventricle of the donor may fail to accommodate to the high pulmonary vascular resistance (PVR) of the recipient. Pulmonary hypertension (PH) due to chronic heart failure with PVRi > 4 Wood units.m2, transpulmonary gradient > 15 mmHg adversely affect the outcome of OHT. In this study we aimed to evaluate management strategies in our pediatric cardiac transplantation candidates with PH and high PVR prior to OHT. METHOD Twenty-six cardiac transplantation candidates (age: 10.2 ± 4.6, 1-17 years) underwent cardiac catheterization for the determination of PVR and pulmonary arterial pressure. They were admitted to the hospital and received 1-3 days of intravenous (IV) vasodilator therapy; 0.5-3 μg/kg/min nitroglyserin and/or 0.5-3 μg/kg/min nitroprusside, 5-15 μg/kg/min dobutamin and/or dopamin to keep systolic blood pressure above 80 mmHg. RESULTS Thirteen patients had dilated cardiomyopathy (CMP), 11 had restrictive CMP, one had hypertrophic CMP and one had congenital heart disease (CHD). Nineteen of the 26 patients underwent OHT. Mean pulmonary arterial pressure of the patients ranged between 11 and 82 mmHg (30.4 ± 16 mmHg) and PVRi between 0.41-21.4 Wood units.m2 (5.3 ± 5.7). Nine patients had PVRi above 4 Wood units.m < sup > 2 < /sup > . Six of these patients had IV treatment for longer than three days and some received specific anti-PH treatment. Eventually they underwent a pulmonary vasoreactivity test with IV iloprost and six had PVRi < 4 Wood units.m < sup > 2 < /sup > . Five of them underwent OHT. CONCLUSION Cardiac transplantation candidates with PH and high PVR should be evaluated after conditioning with vasodilator and inotropic treatment. Specific treatment for PH and vasoreactivity testing may help selected patients reenter the transplantation list.

Abstract
BACKGROUND AND OBJECTIVES Aortic balloon valvuloplasty (ABV) has become the first-line treatment for critical aortic valve stenosis in infants. We aimed to evaluate the short- and mid-term results of patients who underwent ABV during neonatal period, the factors affecting the success and complications of the procedure. METHODS We retrospectively examined 65 patients who underwent ABV during the neonatal period between 1998 and 2017. All hospital records including cardiac catheterization reports, echocardiographic information, and angiographic views were reviewed. RESULTS Forty five (69.2%) of the patients were male and mean follow-up was 6.2 ± 4.9 years (range: 6 months - 19 years). The mean age of the patients at the first ABV was 14.5 ± 10.6 days (range: 1-30 days) and body weight was 3.25 ± 0.6 kg (range: 1.5-4.8 kg). The peak systolic gradient measured during pre-valvuloplasty cardiac catheterization was 73.3 ± 22.7 mmHg (range: 30-142 mmHg), and it decreased to 29.2 ± 12.2 mmHg (range: 5-55 mm Hg) after the procedure. Valvuloplasty was successful in 59 (90.7%) patients. There was no more than mild aortic regurgitation in any patient before valvuloplasty. There was mild aortic regurgitation in 21 patients before the valvuloplasty. In the acute phase after valvuloplasty, 30 patients had mild, 15 had moderate and two had severe aortic regurgitation. There was a significant increase in the degree of aortic regurgitation related to valvuloplasty (p < 0.05). The most important complication of ABV was increased aortic regurgitation (26.2%). Another important complication was femoral artery occlusion; and was detected early after valvuloplasty (61.6%). There was no serious complication or death in the acute phase. CONCLUSIONS In newborns with valvular aortic stenosis, balloon valvuloplasty has become the first choice in many centers due to its high success rate, low mortality and morbidity, and increased clinical experience. Aortic regurgitation and femoral artery occlusion were the most important complications. Although reintervention for residual or recurrent aortic valve stenosis is common during the first year after valvuloplasty, these patients are able to reach advanced ages without the need for surgical intervention. Surgical valvotomy is a good alternative treatment for a small number of patients in whom valvuloplasty fails.

Arslan A, Erdoğan İ, Varan B, Yılmaz M, Özin MB, Tokel NK. Reversible cardiomyopathy-tachycardiomyopathy in children. Turk J Pediatr 2019; 61: 552-559. Tachycardia-induced cardiomyopathy (tachycardiomyopathy) is defined by the presence of a sustained tachycardia that results in left ventricular systolic dysfunction. Restoration of cardiac function is dependent on the control of tachyarrhythmias. We report a series including ten children with tachycardia-induced cardiomyopathy with different etiologies. The medical records of patients with tachycardiomyopathy who were managed in a Pediatric Cardiology Clinic between the years of 2014-2017 were reviewed retrospectively. Ten children (3 female, 7 male) were diagnosed with tachycardiomyopathy. The median age of the patients was 12 years (range: 4-15.8). Five had atrial tachycardia, two had ventricular tachycardia, the others had Mahaim fiber tachycardia, permanent junctional reciprocating tachycardia and atrioventricular reentrant tachycardia. Seven patients had catheter ablation and three patients who had previous heart surgery were treated with antiarrhythmic drugs. Median ejection fraction was 33% (range: 10-48), median left ventricle end-diastolic diameter was 55 mm (range: 30-78). All showed complete recovery with median ejection fraction 60% (range: 55- 78). Two patient with severe heart failure required extracorporeal membrane oxygenation support, one of them had ventricular assist device support but the device was removed after successful ablation. After two years this patient required permanent pacemaker implantation due to complete atrioventricular block. Tachycardia-induced cardiomyopathy is a rare and treatable cause of heart failure. Early recognition is critical, aggressive treatment aimed at controlling the arrhythmia results in symptom resolution and recovery of ventricular function.

Abstract
Pulmonary atresia (PA) and ventricular septal defect (VSD) can occur in a variety of ways, from simple valve atresia to a condition in which circulation to the pulmonary bed occurs through collateral arteries separated from the aorta and there are no real pulmonary arteries, or they are present but hypoplastic. The size of the pulmonary arteries and concomitant complex cardiac lesions are important in making decisions about treatment and correctional alternatives. While complete correction surgeries in the style of a correction of tetralogy of Fallot are performed in simpler cases, many very invasive procedures are also performed and the resulting quality of life is very variable. The size of the pulmonary artery and its branches and the presence of accompanying collateral vessels are determining factors in the management of the disease. In this report, 2 cases of VSD and PA, in which the circulation of the pulmonary arteries was through the coronary arteries, diagnosed as a result of echocardiography performed following murmurs heard during examination, are described. The first patient was 40 days old and the second was 2 days old. In the second case, diagnosis was confirmed by catheter angiography, and in the first case, the final diagnosis was made during surgery. The aim of this report is to emphasize the importance of pulmonary artery size, the presence of pulmonary confluence, the origin of circulation, and concomitant collateral arteries when considering treatment methods.

Catheterization procedures for congenital heart disease include a broad range of procedures with a large spectrum of potential adverse outcomes. We aimed to determine the incidence of various complications during pediatric cardiac catheterizations and to designate the relative risk factors for such complications. All pediatric patients undergoing cardiac catheterizations between January 2005-December 2010 were included. Data are collected prospectively by filling out computerized catheterization reports. Patient records were scanned for potential risk factors retrospectively. Groups were divided based on cardiac diagnosis; type of procedure. Adverse events were categorized into major or minor events. A total of 2662 cardiac catheterizations were performed during this period. The mean age of patients was 53.2±64.3 months. Diagnostic catheterizations were done for 1797 (67.5%) patients, and interventional procedures were done in 865 (32.5%) cases. Adverse events were observed in 688 patients (26%) during 941 procedures. Minor and major events were seen in 21.4% and 7.1% of the procedures respectively. Most frequent major complications were anesthesia related (6%), most frequent minor complications were vascular complications (45.2%). Complications were more frequent in younger patients (p=0.0001), during interventional procedures (p=0.0001). Thirteen patients died after a cardiac catheterization; they were younger and had longer procedures compared to those who survived (p=0.0001). Vascular complications were frequent among younger patients, with prolonged procedure time and vessel access (p < 0.0001). Cyanotic patients had more complications (p < 0.05; OR for major and minor complications: 3.5 and 2 respectively). Minor complications were 2.7 times more likely in ventricular outflow obstructions (p < 0.05). The complication rates of cardiac catheterization in children are low, but not negligible. Defining risk factors will help anticipate adverse events, which will guide in preparation for rescue procedures and improvement of patient safety systems in catheterization laboratories.

Abstract
Background: Brugada syndrome is a disease characterized by a specific electrocardiographic pattern and an increased risk of sudden cardiac death. We present this case with the updated literature to emphasise the need to consider the diagnosis of Brugada syndrome in patients admitted to the emergency ward with sudden cardiac arrest. Case Report: A 16-year-old female patient was admitted to the emergency ward with complaints of weakness and abdominal pain, and she had four cardiac arrests during her evaluation period. She was referred to our clinic for permanent pacemaker implantation. She was on a temporary pace maker after having had C-reactive protein. Her physical exam was normal except for bilaterally decreased lung sounds. Lung x-ray and computed tomography, which were performed by another institution, revealed minimal pleural effusion and nothing else of significance. Blood and peritoneal fluid samples were sterile. Echocardiographic exam and cardiac enzymes were also in the normal ranges. Electrocardiographic showed incomplete right branch block in leads V1 and V2. An ajmaline test revealed specific electrocardiographic findings of the type I Brugada pattern. We proposed implanting an implantable cardioverter defibrillator to the patient as there were positive findings on the ajmaline test as well as a history of sudden cardiac arrest. After this treatment proposal, the patient’s family admitted that she had taken a high dose of verapamil and thus, the encountered bradycardia was associated with verapamil overuse. The ajmaline test was repeated as it was contemplated that the previous positive ajmaline test had been associated with verapamil overuse. Implantable cardioverter defibrillator implantation was proposed again as there was a history of sudden cardiac arrest; however, the family did not consent to implantable cardioverter defibrillator, and the patient was discharged and followed up. Conclusion: Brugada syndrome should be considered for patients who are admitted to the emergency ward with sudden cardiac arrest though surface electrocardiographic is normal. If there is a suspicion of Brugada syndrome, repeated electrocardiographic should be performed on different occasions. Diagnosis can be clarified by upper costal electrocardiographic or by administering Na channel blockers during electrocardiographic performance.

Abstract
Middle aortic syndrome (MAS) follows a course with distal thoracic and abdominal aorta stenosis. It is a rare disease that is usually diagnosed after the first decade of life. Clinical reflection of MAS is often in the form of hypertension and claudication in the lower extremities. Its etiology is unclear, but is known to be associated with congenital or acquired diseases. This pathology, which is accompanied by malignant hypertension, often does not respond to medical treatment. In patients with MAS, surgical treatment is first line recommendation to prevent complications such as hypertension, heart failure, intracranial bleeding, or aortic rupture. In order to draw attention to this disease, presently described is case of high blood pressure detected during routine examination of a child who had no complaint, and discovery of long-segment stenosis in the abdominal aorta identified with echocardiography and conventional angiography.

Abstract
OBJECTIVE Hemangiomas are tumors most commonly encountered in pediatric patients, and are frequently treated with propranolol. However, there are currently no standard methods for evaluating cardiac function in patients prior to propranolol treatment. The present study was designed to aid in the evaluation of pretreatment cardiac and effects of propranolol on vital signs in pediatric hemangioma patients. METHODS A pediatric oncology specialist and a pediatric cardiology specialist examined all patients prior to initiation of propranolol treatment. All patients were examined by the same 2 physicians. Cardiac evaluation included complete echocardiogram and electrocardiography. From September 2009 to January 2014, 146 patients aged 4 days to 10 years were screened. RESULTS No patient had cardiac contraindication to propranolol. The effect of hemangioma on left ventricle size was examined, but left ventricle dilatation was found in only 3 patients. However, 68 patients had abnormal echocardiogram: 17 had patent foramen ovale, 4 had ventricular septal defect, 9 had atrial septal defect (associated with right heart enlargement), 8 had patent ductus arteriosus, 6 had physiologic pulmonary stenosis, and 1 had an aortic coarctation. No contraindications to propranolol or side effects were observed. However, cardiac anatomic defects were more common in this patient group than in the general population. CONCLUSION Hemangiomas in infants or children, even in small or premature infants, can be treated with propranolol without significant cardiac side effects. In addition, large dermal hemangiomas were not found to affect ventricular size in pediatric patients.

Abstract
Tacrolimus is a potent immunosuppressive agent widely used after organ transplantation. In this present study we present eight patients who complained of palpitation after kidney transplantation. Eight out of 31 patients who received tacrolimus after kidney transplantation suffered from tachycardia. Resting electrocardiography, 24 hours Holter monitorization, echocardiography were performed, and serum levels of cardiac troponin T, creatine kinase, CKMB, brain natriuretic peptide and tacrolimus were measured. The median time to palpitation after kidney transplantation was 30 days in seven patients, and one patient complained of palpitation five years after transplantation. Cardiovascular assessment revealed sinus tachycardia in all patients. Beta-blocker was instituted in five patients. After two months all patients were asymptomatic and their pulse rates were within normal limits. Transient sinus tachycardia is a frequent adverse event during tacrolimus therapy in children and young adults, at therapeutic levels. Patients may benefit from beta-blockers.

Magnetic resonance imaging has become an important diagnostic tool in the differential diagnosis of lesions for evaluation of cardiovascular disorders. In magnetic resonance tagging (MRt), tissue elements are magnetically labeled so that their positions can be tracked as a function of time. Thus, MRt evaluates heart wall motion both qualitatively and quantitatively. We present herein the case of a 12-year-old boy who had chest pain, dyspnea on effort and murmur. On cardiac computed tomography, there was focal thickening of the left ventricular posterior wall, similar to a mass. MRt indicated active displacement and deformation of the tags at the level of the hypertrophic myocardium during systole, as with normal myocardium. Thus, the tagged images supported the diagnosis of focal hypertrophic cardiomyopathy (HCM). In view of these results, MRt should be considered as a useful technique for differentiating between a mass-like focal lesion such as neoplasm and HCM.

Abstract
Myocardial infarction and systemic arterial aneurysms are rarely seen during the course of the Kawasaki disease (KD). Herein, we report the case of a 4-month-old Turkish infant who was diagnosed with KD on the 17th day of the illness. On admission, echocardiogram showed multiple coronary arterial aneurysms (CAAs) and massive pericardial effusion. He was given intravenous immunoglobulin, aspirin and anticoagulant drugs. However, the aneurysms progressed to "super giant" CAAs, multiple huge coronary arterial thromboses developed recurrently and caused myocardial ischemia. Furthermore, the conventional angiography revealed multiple giant aneurysms and stenoses in the subclavian, celiac, and iliac arteries, besides CAAs.
