Aim: To investigate the effect of several types of congenital heart disease (CHD) on nutrition and growth.Patients and Methods: The prevalence of malnutrition and growth failure was investigated in 89 patients with CHD aged 1-45 months. They were grouped according to cardiac diagnosis: group aP (n = 26), acyanotic patients with pulmonary hypertension; group ap (n = 5), acyanotic patients without pulmonary hypertension; group cp (n = 42), cyanotic patients without pulmonary hypertension; and group cP (n = 16), cyanotic patients with pulmonary hypertension. Information on socioeconomic level, parental education status, birth weight and nutrition history, number of siblings, and the timing, quality, and quantity of nutrients ingested during weaning period and at the time of the examination were obtained through interviews with parents.Results: There was no significant difference between groups in terms of parental education status, socioeconomic level, duration of breast feeding, and number of siblings (p > 0.05). Group cP patients ingested fewer nutrients for their age compared to other groups. 37 of the 89 patients were below the 5th centile for both weight and length, and 58 of 89 patients were below the 5th centile for weight. Mild or borderline malnutrition was more common in group aP patients. Most group cp patients were in normal nutritional state, and stunting was more common than wasting. Both moderate to severe malnutrition and failure to thrive were more common in group cP patients.Conclusion: Patients with CHD are prone to malnutrition and growth failure. Pulmonary hypertension appears to be the most important factor, and cyanotic patients with pulmonary hypertension are the ones most severely affected. This study shows the additive effects of hypoxia and pulmonary hypertension on nutrition and growth of children with CHD. [ABSTRACT FROM AUTHOR]

Objectives: Alagille syndrome is an autosomal recessive disorder with multisystemic involvement. Patients with Alagille syndrome have many accompanying anomalies such as atypical facial appearance, posterior embryotoxon, butterfly vertebra, cardiac anomalies, and biliary problems. Liver and heart complications can determine the mortality and morbidity of patients with Alagille syndrome. The scarcity of intrahepatic bile ducts leads to cholestatic liver damage. In the heart, although the disease most commonly causes peripheral pulmonary stenosis, patients can present with various structural heart diseases. These cardiac anomalies make intraoperative and postoperative management difficult in patients who need liver transplant. Here, we present 10 cases of liver transplant due to Alagille syndrome., Materials and Methods: From 1988 to the present, our center performed 724 liver transplants, with 366 being pediatric cases; among these, 10 were due to Alagille syndrome. We retrospectively examined patient morphological findings, cardiac pathology, and perioperative complications., Results: Average weight and age of patients were 11 kg and 4.9 years, respectively. Eight patients had atypical facial appearance, 5 had posterior embryotoxon, and 6 had butterfly vertebra. Portoenterostomy (Kasai procedure) was performed in 3 patients because of suspicion of early biliary atresia. Cardiac pathology was present in 8 patients, with peripheral pulmonary stenosis being the most common (present in 8 patients). One patient had cardiac catheterization, with right ventricular and pulmonary artery pressures measured at 110 and 37 mm Hg, respectively. Two patients required preoperative pulmonary angioplasty. Two patients had double superior vena cava. No complications occurred in any patient during the anhepatic phase with appropriate volume replacement. No patients had early mortality., Conclusions: Cardiac anomalies should be identified in patients with Alagille syndrome to minimize complications before liver transplant. If necessary, cardiac catheterization should be performed for pulmonary stenosis. Peripheral pulmonary stenosis does not constitute an absolute contraindication to liver transplant.

Objectives: Cardiovascular diseases are an important cause of mortality and morbidity in children with chronic renal failure. Cardiac evaluation and followup are crucial for these patients before and after renal transplant. Echocardiography is a noninvasive imaging modality that allows for the assessment of cardiac structure and function., Materials and Methods: We retrospectively investigated pretransplant and posttransplant echocardiography findings for 55 pediatric patients who had underwent kidney transplant. We recorded patient characteristics before and after transplant, including age, sex, follow-up period, etiology of renal failure, left ventricular systolic and diastolic diameters and the associated z scores, left ventricular mass indexes and z scores, ejection fraction and fractional shortening, aortic valve and atrioventricular valve insufficiencies, presence of pulmonary hypertension, and pericardial effusion (if any) in echocardiography. All participants underwent echocardiography at baseline and after 6 months following the transplant procedure., Results: Posttransplant echocardiography evaluations showed that the z scores of left ventricular systolic and diastolic diameters decreased significantly, mitral regurgitation decreased, and left ventricular systolic functions and left ventricular mass index increased., Conclusions: Our study revealed that kidney transplant has a beneficial effect on the cardiovascular status of patients with end-stage renal disease, as shown by improvements in both structural and functional echocardiographic features. Cardiac functions must be monitored regularly before and after transplant. Transplantation is the optimal treatment option for preservation and improvement of cardiovascular functions.

Background: Cardiovascular system involvement is quite common and the leading cause of morbidity and mortality in patients with Williams syndrome (WS), most of whom need surgery. The present study aimed to provide a detailed evaluation of the features of surgical procedures and outcomes of patients with WS given as single-center experience, and additionally to make a detailed review from Türkiye., Materials and Methods: Thirty-five children with WS diagnosed between the years 1992 and 2021 were evaluated retrospectively including cardiovascular data, surgical treatment features, and outcomes. A total of six articles from Türkiye were evaluated., Results: A total of 35 patients with Williams Syndrome (24 male) with a median age of cardiologic diagnosis of 6 months (range, 2 days-6 years) were evaluated. The cardiac defects of the patients with WS were found as supravalvular aortic stenosis (SVAS) (n=30, 85%) and peripheral pulmonary stenosis (PPS) (n=21, 65%). Additional cardiac anomalies were seen in 71% patients. The rate of SVAS and PPS surgery in all patients with WS was 77.1%. The median surgical age of the patients was 2.5 years (range, 7 months-15.5 years). No patients died due to surgery. But one patient died because of ventricular tachycardia due to anesthesia at the beginning of angiography. A total of 138 (63% male) patients with WS were evaluated from the articles published in Türkiye. Of 138 patients, 64.4% had SVAS, 52.1% had PPS, and 39.8% had additional cardiac anomaly. The median follow-up period ranged from 17 months to 18 years, and six (4.3%) patients died in the early postoperative period., Conclusion: Cardiovascular system involvement is extremely common and is the leading cause of morbidity and mortality in patients with WS, often requiring surgical intervention. As seen in our study including 35 patients with WS and in publications from Türkiye, SVAS in patients with WS generally requires surgery, especially in the first year of life. PPS, on the other hand, requires surgery less frequently than SVAS, and pulmonary stenosis appears to decrease over time., Competing Interests: The authors declare that there is no conflict of interest.

Introduction: Little data are available concerning the methods used in the long-term follow-up of Fontan patients. We analyzed the association between serum N-terminal pro-brain natriuretic peptide levels, conventional echocardiography findings, exercise parameters, and dyssynchrony measurements in patients who underwent Fontan surgery., Methods: This study included 28 patients who underwent Fontan surgery (mean age 12.8 ± 4.36 years) and 27 healthy controls (mean age 12.5 ± 3.76 years). Echocardiography examinations and exercise tests were performed in both groups. The systemic ventricle was examined via echocardiography, dyssynchrony measurement was performed, the systemic ventricular myocardial performance index was calculated, and serum N-terminal pro-brain natriuretic peptide levels were measured for all subjects., Results: Lower cardiac output, stroke volume, maximal work, chronotropic index, maximal oxygen uptake, and higher N-terminal pro-brain natriuretic peptide levels were observed in the Fontan group than in the control group (p < 0.05). A negative correlation was found between physical exercise parameters and N-terminal pro-brain natriuretic peptide levels and dyssynchrony measurements., Conclusion: Measurements of exercise capacity, serum N-terminal pro-brain natriuretic peptide levels, and dyssynchrony measurement were more valuable than conventional methods for assessing patients' clinical and functional status. Dyssynchrony measurements provided better information about ventricular status than did conventional echocardiography studies. While patients' systolic function determined by conventional echocardiography was normal, dyssynchrony measurements showed the opposite result. The negative relationship between serum N-terminal pro-brain natriuretic peptide levels, dyssynchrony measurements, and exercise capacity suggests that these parameters should be investigated further in Fontan patients.

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.

Objectives: 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.

Background: 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., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2021, Turkish Society of Cardiovascular Surgery.)

Introduction: We aimed to present the risk factors, clinical and laboratory findings, treatment management, and risk factors for morbidity and mortality of infective endocarditis (IE) as well as to relate experiences at our center., Method: We retrospectively analyzed data of 47 episodes in 45 patients diagnosed with definite/possible IE according to the modified Duke criteria between May 2000 and March 2018., Results: The mean age of all patients at the time of diagnosis was 7.6±4.7 years (range: 2.4 months to 16 years). The most common symptoms and findings were fever (89.3%), leukocytosis (80.8%), splenomegaly (70.2%), and a new heart murmur or changing of pre-existing murmur (68%). Streptococcus viridans (19.1%), Staphylococcus aureus (14.8%), and coagulase-negative Staphylococci (10.6%) were the most commonly isolated agents. IE-related complications developed in 27.6% of the patients and the mortality rate was 14.8%., Conclusion: We found that congenital heart disease remains a significant risk factor for IE. The highest risk groups included operated patients who had conduits in the pulmonary position and unoperated patients with a large ventricular septal defect. Surgical intervention was required in most of the patients. Mortality rate was high, especially in patients infected with S. aureus, although the time between the onset of the first symptom and diagnosis was short. Patients with fever and a high risk of IE should be carefully examined for IE, and evaluation in favor of IE until proven otherwise will be more accurate. In high-risk patients with prolonged fever, IE should be considered in the differential diagnosis.

Objective: To investigate the effectiveness of the metabolic markers homocysteine, vitamin B12, folate, and B-type natriuretic peptide in maternal and cord blood for detecting congenital heart disease. Methods: Homocysteine, vitamin B12, folate, and B-type natriuretic peptide concentrations in maternal and cord blood samples at term were measured in the case ( n  = 42) and control ( n  = 43) groups with and without fetal congenital heart disease, respectively. Additionally, newborns with congenital heart disease were divided into two subgroups: those with ( n  = 30) and without ( n  = 8) 6-month infant survival. The case and control groups and case subgroups were compared with each other with respect to maternal age, gravidity, parity, gestational age at delivery, birth weight, maternal and cord blood levels of homocysteine, vitamin B12, folate, and B-type natriuretic peptide, and arterial cord blood pH and base excess values. Statistical analyses were performed using SPSS for Windows, version 22.0. The Student's t -test, the Mann-Whitney U test, and the χ 2 test were used where appropriate. A p value of < .05 was considered statistically significant. Results: Mean maternal age, birth weight and median gravidity, parity and gestational age at delivery were not significantly different between the case and control groups, as well as between the case subgroups (all p  > .05). Homocysteine and B-type natriuretic peptide levels in cord blood samples were significantly higher, whereas folate levels were significantly lower in the case group compared with the control group (all p  < .05). Cord blood B-type natriuretic peptide levels were significantly higher ( p  < .05). Cord blood B-type natriuretic peptide levels were significantly higher ( p  < .05) and arterial cord blood pH values were significantly lower ( p High cord blood B-type natriuretic peptide and homocysteine levels and low cord blood folate levels at term may be useful for predicting congenital heart disease in the neonate. Neonates with congenital heart disease who have high cord blood B-type natriuretic peptide and low pH values may have adverse outcomes.Conclusion: High cord blood B-type natriuretic peptide and homocysteine levels and low cord blood folate levels at term may be useful for predicting congenital heart disease in the neonate. Neonates with congenital heart disease who have high cord blood B-type natriuretic peptide and low pH values may have adverse outcomes.

Objective: Double-chambered right ventricle is characterised by division of the outlet portion of the right ventricle by hypertrophy of the septoparietal trabeculations into two parts. We aim to report our experiences regarding the presenting symptoms of double-chambered right ventricle, long-term prognosis, including the recurrence rate and incidence of arrhythmias after surgery., Methods: We retrospectively investigated 89 consecutive patients who were diagnosed to have double-chambered right ventricle and underwent a surgical intervention from 1995 to 2016. The data obtained by echocardiography, cardiac catheterisation, and surgical findings as well as post-operative follow-up, surgical approaches, post-operative morbidity, mortality, and cardiac events were evaluated., Results: Median age at the time of diagnosis was 2 months and mean age at the time of operation was 5.3 years. Concomitant cardiac anomalies were as follows: perimembranous ventricular septal defect (78 patients), atrial septal defect (9 patients), discrete subaortic membrane (32 patients), right aortic arch (3 patients), aortic valve prolapse and/or mild aortic regurgitation (14 patients), and left superior caval vein (2 patients). The mean follow-up period was 4.86 ± 4.6 years. In these patients, mean systolic pressure gradient in the right ventricle by echocardiography before, immediately, and long-term after surgical intervention was 66.3, 11.8, and 10.4 mmHg, respectively. There were no deaths during the long-term follow-up period. Surgical reinterventions were performed for residual ventricular septal defect (2), residual pulmonary stenosis (1), and severe tricuspid insufficiency (1)., Conclusion: The surgical outcomes and prognosis of double-chambered right ventricle are favourable, recurrence and fatal arrhythmias are unlikely in long-term follow-up.

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.

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.

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.

Objective: We aimed to review symptoms, findings, surgical treatment options, short- and mid-term outcomes, and reoperation rate of patients diagnosed with of left coronary artery from the pulmonary artery (ALCAPA) of an anomalous origin in our institution., Methods: From May 2000 to March 2018, 33 patients who had left coronary artery originating from the pulmonary artery were retrospectively examined. The clinical features of patients, diagnostic tools and their efficacy, outcomes of surgical repair, and problems during follow-up were evaluated., Results: Thirty-three patients (22 females, 11 males) were included in the study. At the time of surgery, the median age and weight of patients were 6 months (minimum/maximum, 1-166 months) and 6.5 kg (minimum/maximum, 3-38.5 kg), respectively. The mean follow-up was 5±3.5 years (range, 1-16 years). Dyspnea, tachypnea, diaphoresis, prolonged feeding time, and developmental delay were common presenting signs and symptoms. It was determined that all the patients who were diagnosed at another center reached our center for surgical treatment within 1 month. Twenty-three (69.7%) patients had pathologic Q wave with anterior and/or anterolateral myocardial infarction signs on an electrocardiogram (ECG), whereas 22 (66.6%) patients had ST-T segment changes. Twenty-one (63.6%) patients had cardiomegaly on the telecardiogram. A reimplantation surgery was performed to 22 patients and 10 patients underwent the Takeuchi procedure. In addition to ALCAPA repair, 5 patients needed mitral valve plasty. Atrial septal defect (ASD) and ventricular septal defect (VSD) were closed in one patient, and Tetralogy of Fallot was totally corrected in another. At discharge, there was a significant improvement in left ventricular (LV) systolic functions. At the last visit, all patients had normal LV systolic functions except four who had mild dysfunction. The mean follow-up of the four patients was 2.8 years. In the early postoperative period, complications were seen in 10 patients. Five patients died in the early postoperative period, while one patient died 9 months after the ALCAPA surgery because of low cardiac output syndrome that developed after mitral repair., Conclusion: Patients with ALCAPA commonly present with congestive heart failure symptoms. When the diagnosis is confirmed in these patients, surgical treatment should not be delayed. The availability of surgical center and surgery outcomes for ALCAPA diagnosed patients are comparable with other countries, but the delay in the diagnosis of disease is still a problem in our country.

Background: The aim of this study was to evaluate the early and mid-term results of interventional cardiac catheterization and procedure-related complications in infants weighing <2,000 g., Methods: Between May 1998 and April 2017, 22 patients (14 males, 8 females; mean age 14±8.4 days; range, 1 to 30 days) weighing <2,000 g who underwent a total of 23 interventional cardiac catheterization were retrospectively analyzed. Procedures were balloon coarctation angioplasty in 14, balloon atrial septostomy in five, balloon aortic valvuloplasty in one, balloon pulmonary valvuloplasty in one, patent ductus arteriosus closure in one, and stent placement in the ductus in one patient. Another patient underwent balloon coarctation angioplasty and balloon aortic valvuloplasty in the same session., Results: The overall success rate of the interventional procedures was 95.6%. The mean follow-up was 3.2±1.6 years (range, 1 to 5.5) for 18 patients with available records. The rate of serious complications was 18%. The most frequent complications in the early period were low hemoglobin levels requiring erythrocyte suspension transfusion (54.5%) and vascular injury (54.5%). Two patients required reintervention, one patient required surgery after the second intervention, and three patients required only surgery. Six patients underwent palliative interventional procedures, and interventional procedures led to definitive treatment in five patients., Conclusion: The mortality and morbidity rate of surgery is high in premature under 2,000 g infants and interventional heart catheterization can be life-saving in this patient group, although it is associated with significant complications in low birth weight newborns., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2019, Turkish Society of Cardiovascular Surgery.)
