RESUMO

Background: This second harvest of the Congenital Heart Surgery Database intended to compare current results with international databases. Methods: This retrospective study examined a total of 4007 congenital heart surgery procedures from 15 centers in the Congenital Heart Surgery Database between January 2018 and January 2023. International diagnostic and procedural codes were used for data entry. STAT (Society of Thoracic Surgeons and European Association for Cardiothoracic Surgery) mortality scores and categories were used for comparison of the data. Surgical priority status was modified from American Society of Anesthesiologist guidelines. Centers that sent more than 5 cases to the database were included to the study. Results: Cardiopulmonary bypass and cardioplegic arrest were performed in 2,983 (74.4%) procedures. General risk factors were present in 22.6% of the patients, such as genetic anomaly, syndrome, or prematurity. Overall, 18.9% of the patients had preoperative risk factors (e.g., mechanical ventilation, renal failure, and sepsis). Of the procedures, 610 (15.2%) were performed on neonates, 1,450 (36.2%) on infants, 1,803 (45%) on children, and 144 (3.6%) on adults. The operative timing was elective in 56.5% of the patients, 34.4% were urgent, 8% were emergent, and 1.1% were rescue procedures. Extracorporeal membrane oxygenation support was used in 163 (4%) patients, with a 34.3% survival rate. Overall mortality in this series was 6.7% (n=271). Risk for mortality was higher in patients with general risk factors, such as prematurity, low birth weight neonates, and heterotaxy syndrome. Mortality for patients with preoperative mechanical ventilation was 17.5%. Pulmonary hypertension and preoperative circulatory shock had 11.6% and 10% mortality rates, respectively. Mortality for patients who had no preoperative risk factor was 3.9%. Neonates had the highest mortality rate (20.5%). Intensive care unit and hospital stay time for neonates (median of 17.8 days and 24.8 days, respectively) were also higher than the other age groups. Infants had 6.2% mortality. Hospital mortality was 2.8% for children and 3.5% for adults. Mortality rate was 2.8% for elective cases. Observed mortality rates were higher than expected in the fourth and fifth categories of the STAT system (observed, 14.8% and 51.9%; expected, 9.9% and 23.1%; respectively). Conclusion: For the first time, outcomes of congenital heart surgery in Türkiye could be compared to the current world experience with this multicenter database study. Increased mortality rate of neonatal and complex heart operations could be delineated as areas that need improvement. The Congenital Heart Surgery Database has great potential for quality improvement of congenital heart surgery in Türkiye. In the long term, participation of more centers in the database may allow more accurate risk adjustment.

RESUMO

BACKGROUND: Transposition of the great arteries is a severe CHD that affects term neonates. The presence of major aortopulmonary collateral arteries in neonatal transposition of the great arteries patients is rare. This study investigated the clinical and haemodynamic implications of the presence of major aortopulmonary collateral arteries in neonatal transposition of the great arteries patients who underwent an arterial switch operation. MATERIALS AND METHODS: The study was a retrospective analysis conducted on neonates diagnosed with transposition of the great arteries who underwent arterial switch operation within the period from 1 May 2020 to 1 January 2023 at two high-patient-volume paediatric cardiac surgery centres in Turkey. The patients' demographic characteristics, echocardiographic features, and clinical data were analysed. Additionally, the possible clinical effects of the presence of major aortopulmonary collateral arteries were statistically evaluated. RESULTS: Two hundred cases of neonatal transposition of the great arteries were included in this study, with 55% of the cases male. All the patients underwent arterial switch operation. The median age at the time of arterial switch operation was 5 days (interquartile range 3-7), with a median weight of 3,100 g (interquartile range 2,900-3,400). The median pre-operative saturation level was 76% (interquartile range 70-82%). Prior to arterial switch operation, 32 patients underwent balloon atrial septostomy.In all the patients, the interatrial septum was checked to determine if the atrial septum was intact. A patent foramen ovale (≤ 3 mm) was found in 112 patients, and a non-restrictive atrial septal defect (> 3 mm) was found in 88. Forty-eight patients had ventricular septal defects, and 72 had coronary anomalies. Major aortopulmonary collateral arteries were found in 4 patients pre-operatively and in 12 patients after arterial switch operation (echocardiography, n = 8; angiography, n = 4). Of the patients with post-operative detection of cumulative number of major aortopulmonary collateral arteries were on post-operative day 1 in 2 patients, on post-operative day 3 in 5 patients, on post-operative day 7 in 6 patients, and on post-operative day 14 in 11 patients.Transcatheter closure was performed in 3 cases due to recurrent extubation failure. Major aortopulmonary collateral artery shrinkage was observed in one case under medical treatment. The length of paediatric cardiac intensive care unit stay (10 days versus 8 days; p < 0.005), mechanical ventilator time (4 days versus 2 days; p = 0.02), and inotrope use time (5 days versus 3 days; p = 0.04) were higher in the major aortopulmonary collateral artery cases than patients without major aortopulmonary collateral artery. CONCLUSION: Major aortopulmonary collateral arteries are frequent in transposition of the great arteries patients and may have clinical effects. The presence of major aortopulmonary collateral arteries should be investigated in patients who do not have a favourable post-operative course after arterial switch operation.

RESUMO

Prolonged pleural effusion is a fairly common condition which has considerable impact on complicated and longer hospital stays after Fontan surgery. Identifying the patient population prone to have pleural effusions is still seeking for an answer. This study is to determine the variables that may predict prolonged pleural effusion according to the data of 69 patients who underwent Fontan operation between June 2018 and December 2020 and survived to date. Prolonged pleural effusion was defined as the need for a chest tube for more than 7 days. Two patient groups, with and without prolonged effusion, were compared in terms of pre-, peri-, and post-operative variables. The patients were subdivided into "high-risk" and "low-risk" groups based on the pre-operative catheterisation data. The most frequent main diagnosis was tricuspid atresia (n: 13, 19%). Among 69 patients, 28 (40%) had prolonged pleural effusion whereas 11 (16%) had effusions that lasted longer than 14 days. Ten patients among prolonged effusion group (35%) had pulmonary atresia coexistent with the main diagnosis. Fontan operation was performed in 6 patients (8.7%) over the age of 10, and 4 of these patients (67%) had prolonged pleural effusion. Among numerous variables, statistical significance between the two groups was achieved in pre-operative mean pulmonary artery pressure, post-operative albumin, C-reactive protein levels, length of hospital stay, duration of chest tube drainage, and amount of effusion per day. Early recognition and treatment strategies with routine medical protocol use remain to be the cornerstone for the management of post-operative prolonged pleural effusions after Fontan surgery.

RESUMO

INTRODUCTION: Isolated aortic coarctation performed through a left thoracotomy resection and end-to-end anastomosis results in low mortality and morbidity rates. Recoarctation and late hypertension are among the most important complications after such repairs. In this study, we reviewed the results of children who underwent left-side thoracotomy to correct an isolated aortic coarctation. METHOD: A consecutive sample of 90 patients who underwent resection and extended end-to-end anastomosis through a left-side thoracotomy in our centre between 2011 and 2021 was retrospectively analysed. The patients' preoperative characteristics, operative data, and post-operative early and long-term results were examined. RESULTS: All patients underwent resection and extended end-to-end anastomosis. A pulmonary artery band was applied simultaneously to three (3.3%) patients, and an aberrant right subclavian artery division was applied to one (1.1%) patient. The mean cross-clamp time was 29.13 ± 6.97 minutes. Two (2.2%) patients required reoperation in the early period. Mortality was observed in one (1.1%) patient in the early period. Eight (8.8%) patients developed recoarctation, of whom four (4.4%) underwent reoperation and four (4.4%) underwent balloon angioplasty. Twenty-two (26.8%) patients received follow-up antihypertensive treatment. The mean follow-up period was 41.3 ± 22.8 months. No mortality was observed in the late period. CONCLUSION: Isolated coarctation is successfully treated with left-side thoracotomy resection and an extended end-to-end anastomosis technique with low mortality, morbidity, and low long-term recoarctation rates. Long-term follow-up is required due to the risks of early and late post-operative recoarctation, which requires reintervention.

RESUMO

AIM: In this study, we investigated changes in newborns' cerebral and intestinal blood flow who had undergone aortic arch surgery. METHOD: This study was carried out prospectively as a preliminary study in patients younger than 30 days at the time of aortic arch reconstruction between 1 August and 1 December, 2019. Cerebral and gastrointestinal hemodynamics were evaluated with Doppler USG before and 7 days after the operation. The middle cerebral artery (MCA) and celiac artery (CA) were used as measurement sites. Patients' peak systolic velocity (PSV), mean systolic velocity (MV), end diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI) were evaluated. RESULTS: A total of 16 patients enrolled in the study. The patients' median weight was 3.2 kg (2.7-4.5 kg), and age was 21 days (7-30 days). Six of them were female. Seven of the patients who underwent arcus reconstruction had an additional ventricular septal defect. The preoperative Doppler USG values of patients' were as follows: for MCA, the mean PSV was 37 ± 12 cm/s, EDV 12 ± 5 cm/s, MV 22 ± 19 cm/s, RI 0.70 ± 0.03, PI 1.24 ± 0.23, and for CA mean PSV was 67 ± 32 cm/s, EDV 29 ± 14 cm/s, MV 24 ± 9 cm/s, RI 0.79 ± 0.27, and PI 1.63 ± 0.89. Doppler USG values of patients' at the postoperative seventh day were as follows: for the MCA, mean PSV 41 ± 13 cm/s, EDV 13 ± 4 cm/s, MV 25 ± 10 cm/s, RI 0.64 ± 0.05, PI 1.23 ± 0.20, and for the CA mean PSV 70.5 ± 34 cm/s, EDV 32 ± 16 cm/s, MV 26 ± 8 cm/s, RI 0.75 ± 0.1, and PI 1.60 ± 0.38. There was a significant decrease in RI of both MCA and CA on the postoperative 7th day compared to the preoperative period (p < 0.05). CONCLUSION: In newborns, there are significant changes in cerebral and intestinal blood flows after aortic arch surgery. RI decreased significantly, especially in the CA and MCA.

RESUMO

INTRODUCTION: Echocardiography (echo) is the primary non-invasive imaging modality for the assessment of congenital heart disease (CHD). Computed tomography angiography (CTA) also has potential to examine the anatomy of complex heart anomalies as well as extracardiac involvement. OBJECTIVES: The aim of this study is to determine the impact of new CTA technology in the diagnosis of CHD and to compare echo and CTA in terms of diagnostic accuracy. METHODS: Forty-five patients who underwent preoperative echo and CTA assessment in the intensive care unit were included in this study. The results were assessed for three main types of CHD (cardiac malformations, cardiac-major vessel connections and major vessels). The main groups were also divided into subgroups according to surgical features in order to assess them more objectively. Imaging methods were compared for diagnostic accuracy, sensitivity and specificity, while surgical findings were accepted as the gold standard. RESULTS: Patients' median age and weight were two months (three days-eight years) and 12 kg (2.5-60 kg), respectively. In 45 operated cases, 205 subgroup malformations were assessed. Diagnostic accuracy was significantly greater in echo (echo vs. CTA: 98.4% and 96.2% [chi-square=6.4, p=0.011]). During surgery, 84 cardiac malformations (echo vs. CTA: 97.4% and 95.1% [chi-square=4.9, p=0.03]), 47 cardiac-major vessel connections (echo vs. CTA: 98.3% and 95.4% [chi-square=7.5, p=0.03]), and 74 major vessel malformations (echo vs. CTA: 96% and 98% [chi-square=1.8, p=0.48]) were confirmed. CONCLUSION: Echocardiography and CTA are imaging methods with high diagnostic accuracy in children with CHD. The use of echocardiography together with CTA, especially for the visualization of extracardiac anatomy, provides additional information for clinicians.

RESUMO

PURPOSE: This study was planned to assess the application of three-dimensional (3D) cardiac modeling in preoperative evaluation for complex congenital heart surgeries. METHODS: From July 2015 to September 2019, 18 children diagnosed with complex congenital heart diseases (CHDs) were enrolled in this study (double outlet right ventricle in nine patients, complex types of transposition of the great arteries in six patients, congenitally corrected transposition of the great arteries in two patients, and univentricular heart in one patient). The patients' age ranged from 7 months to 19 years (median age, 14 months). Before the operation, 3D patient-specific cardiac models were created based on computed tomography (CT) data. Using each patient's data, a virtual computer model (3D mesh) and stereolithographic (SLA) file that would be printed as a 3D model were generated. These 3D cardiac models were used to gather additional data about cardiac anatomy for presurgical decision-making. RESULTS: All 18 patients successfully underwent surgeries, and there were no mortalities. The 3D patient-specific cardiac models led to a change from the initial surgical plans in 6 of 18 cases (33%), and biventricular repair was considered feasible. Moreover, the models helped to modify the planned biventricular repair in five cases, for left ventricular outflow tract obstruction removal and ventricular septal defect enlargement. 3D cardiac models enable pediatric cardiologists to better understand the spatial relationships between the ventricular septal defect and great vessels, and they help surgeons identify risk structures more clearly for detailed planning of surgery. There was a strong correlation between the models of the patients and the anatomy encountered during the operation. CONCLUSION: 3D cardiac models accurately reveal the patient's anatomy in detail and are therefore beneficial for planning surgery in patients with complex intracardiac anatomy.

RESUMO

OBJECTIVE: We report the early and long-term results of the strategies and surgical methods used in our center to treat pediatric patients who underwent surgical intervention to correct Ebstein anomaly (EA) in our center. MATERIALS AND METHODS: In our study, a consecutive sample of 29 patients who underwent surgery for EA between February 2011 and February 2020 in our center were evaluated retrospectively. RESULTS: The 29 patients underwent a total of 40 operations. Univentricular repair was performed in 5 (17.2%), 1.5 ventricular repair in 5 (17.2%), and biventricular repair in the remaining 19 (65.5%) patients. Cone reconstruction (CR) was performed in eight (27.5%), non-Cone tricuspid valve (TV) repair technique in five (17.2%), ring annuloplasty in two (6.9%), and TV replacement in two patients (6.9%) who had undergone biventricular repair. In two patients (6.9%), only close an atrial septal defect. Two (6.9%) patients underwent a second operation for advanced tricuspid regurgitation (TR) in the early period. None of the 15 patients who underwent CR and TV plasty had moderate or advanced TR before discharge. Early mortality was seen in 1 (3.4%) patient. The mean follow-up period of the patients was 48.4±27.6 months. Three (10.7%) of the patients who were discharged after their first operation later underwent a second operation for TV regurgitation in the long term. No mortality was observed in any patient during long-term follow-up. CONCLUSION: Surgical treatment of EA is difficult, but its overall results are good. The anatomical repair rate is lower in neonatal and infant patients requiring surgery, but most of these patients underwent biventricular repair. Our long-term results demonstrated an acceptable survival rate, low mortality in the early postoperative period, and low incidence of re-intervention and morbidity.

RESUMO

OBJECTIVES: A new congenital heart surgery database (CKCV) with real-time online reporting function was recently developed in Turkey. All standard international parameters were used, but Aristotle Comprehensive Complexity score was modified. In this study, the first analysis of the CKCV Database is reported. METHODS: The CKCV Database included 2307 procedures from 12 centers between January 2018 and March 2020. All parameters, including 10 real-time online reports, which represent the number of centers, number and mortality rates of all procedures, number of extracorporeal membrane oxygenation (ECMO) and results, details of postoperative complications, age-group statistics, analysis for priority status, mean intensive care and hospital stay durations of the procedures, results of Aristotle Basic, Modified Aristotle Comprehensive (MACC) and Society of Thoracic Surgeons-European Association (STAT) Score Categories, comparison of centers were analyzed. RESULTS: Most common 10 procedures were ventricular septal defect (VSD) repair (n = 273), tetralogy of Fallot (TOF) repair (n = 243), atrial septal defect (ASD) repair (n = 181), complete AVSD repair (n = 95), cavopulmonary anastomosis (n = 81), systemic to pulmonary shunt (n = 79), modified Fontan (n = 71), subaortic resection, (n = 66) PA banding (n = 66), and arterial switch operation (n = 66). Cardiopulmonary bypass was used in 84.6% of the procedures. Overall mortality rate was 6.0%. A total of 618 major and 570 minor complications were observed in 333 and 412 patients, respectively. According to six MACC categories, number of the patients and mortality rates were I (293; 0.3%); II (713; 1.4%); III (601; 3.3%); IV (607; 12%); V (84; 35.7%); and VI (9; 55.6%), respectively. Analysis of five STAT Categories showed 0.7, 3.8, 5.4, 14.9, and 54.7% mortality rates. CONCLUSIONS: CKCV Database has a great potential for nationwide quality improvement studies. Users could instantly analyze and compare their results to national and international aggregate data using a real-time online reporting function. This is the first multicenter congenital database study in Turkey.

RESUMO

BACKGROUND: This study aims to evaluate early postoperative arrhythmias in children undergoing congenital cardiac surgery. METHODS: A total of 670 pediatric patients (355 males, 315 females; median age: 4 months; range, 1 day to 18 years) who underwent cardiac surgery due to congenital heart defects between December 2018 and November 2019 were included. The rate of postoperative arrhythmias, diagnosis, potential risk factors, and management strategies were evaluated. Multivariate regression analysis was used to identify significant factors of development of postoperative arrhythmias. RESULTS: Tachyarrhythmia was detected in 54 patients (8.1%), and the most common tachyarrhythmia was junctional ectopic tachycardia. Medical treatment was required in 25/38 (66%) of junctional ectopic tachycardia patients. Amiodarone was initiated in 18, dexmedetomidine in five, and flecainide + amiodarone in two of the patients. Different degrees of atrioventricular block were observed in 30 patients (4.5%). In 12 patients, permanent pacemakers were implanted during hospitalization. Age at the time of surgery under one-year-old, high inotropic scores, prolonged operation time, and high Aristotele"s scores were independent risk factors associated with early postoperative arrhythmia (p<0.05). The most common operations associated with early postoperative arrhythmia were left ventricular outflow tract, (6/20, 30%), complete atrioventricular septal defect (13/53, 24%), and tetralogy of Fallot (20/134, 14%) surgeries. CONCLUSION: Cardiac arrhythmias are common in the early period after congenital heart surgery in children. The diagnosis and frequency of arrhythmias may vary according to different surgical procedures.

RESUMO

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is the second most common pediatric cardiomyopathy. Although there is a large body of literature about HCM in adults, there is limited information on HCM in childhood. We evaluated various aspects of pediatric HCM patients treated at our center. METHODS: We identified 152 pediatric patients with HCM between October 2011 and October 2019. Clinical history, invasive (ICD, pacemaker, electrophysiologic study, catheter ablation therapy) and non-invasive (ECG, holter moniterization, echocardiography, cardiac MR, genetic study, medicam treatment) data were collected and evaluated. RESULTS: The mean ± standard deviation age of patients was 8.9 ± 5.7 years (1 month-18 years) and 67.8% were male. The most frequent clinical symptoms were murmur and palpitations. Three cases (2%) had aborted sudden death as the first manifestation of HCM. Of these patients, 120 (78.9%) had non-syndromic HCM and 32 (27.2%) had syndromic HCM. Asymmetric septal hypertrophy was common (48.3%) in the non-syndromic group, whereas concentric hypertrophy was common (56.2%) in syndromic group. Left ventricular outflow tract obstruction (LVOTO) occurred in 39 (25.6%) patients. Nine (5.9%) patients underwent electrophysiologic study and/or ablation and 16 patients underwent surgical intervention. Implantable cardioverter defibrillator (ICD) insertion was performed in 38 patients (26 transvenous, 12 epicardial). ICDs were inserted in three (7.9%) patients for secondary prevention; in the remaining patients (92.1%) the devices were placed for primary prevention. Mean SD follow-up time was 27.1 ± 22 months. Five (3.3%) patients died during the follow-up. No patient had heart transplantation or a long-term assistive device. CONCLUSION: The etiology of HCM is heterogeneous and present at any age. It is important to determine the timing of surgery and potential risks for sudden cardiac arrest. As most cases of HCM are familial, evaluation of family members at risk should be a routine component of clinical management.

RESUMO

BACKGROUND: Permanent pacemaker (PM) implantation is performed for various indications and by different techniques in children; however, many problems with lead performance are encountered during follow-up. This study aims to evaluate the possible effects of different lead types and implantation techniques on pacing at early and midterm in children with a permanent PM. PATIENTS AND METHODS: Pediatric patients who underwent permanent PM system implantation at our tertiary cardiac surgery center between January 1, 2010 and January 1, 2020 were evaluated retrospectively. Patients were categorized in the epicardial pacing lead (EP), transvenous pacing lead (TP), and transvenous bipolar lumenless (Select Secure [SS]) lead groups according to the lead implantation technique and lead type with the same manufacturer. Groups were evaluated statistically for demographic features, pacing type and indication for implantation, lead electrical performance, lead failure, complications, and outcome. RESULTS: Over 10 years, 323 lead implantations were performed on 167 patients (96 males, median age 68 months [5 days-18 years]). Of 323 leads, 213 (66%) were EP, 64 (20%) were TP, and 46 (14%) were SS. Of the total, 136 of the leads were implanted in atria, and 187 were implanted in ventricles. Primary pacing indications were postoperative complete atrioventricular (AV) block (n = 95), congenital AV block (n = 71), sinus node dysfunction (n = 13), and acquired complete AV block (n = 1). Additional cardiac diseases were present in 115 patients (69%). No statistically significant difference was observed in gender, syndrome, or pacing indication (P > .05). Atrial and ventricular capture, threshold, sensing, and lead impedance measurements were not significantly different at the initial and follow-up periods (P > .05). The median follow-up duration was 3.3 years (6 months-10 years). Twenty lead failures were determined in 15 patients (EP: 14 lead failures in 10 patients; TP: two lead failures in two patients; and SS: four lead failures in three patients) during follow-up, and no statistically significant difference was found between groups (P = .466). The 5-year lead survival was 98% for TP, 95% for EP, and 90% for SS; the 10-year lead survival was 90% for TP, 70% for EP, and 70% for SS. There was no mortality related to chronic pacing or due to the procedure of implantation. CONCLUSIONS: Despite improvements in technology, lead failure is still one of the most critical problems during these patients' follow-up. Early to midterm lead survival rates of all three lead types were satisfactory.

RESUMO

OBJECTIVE: The effects of Vasoactive-Ventilation-Renal (VVR) score on the evaluation of pediatric heart surgery results were investigated in this study. METHODS: This retrospective study included children younger than 18 years of age who were operated for congenital heart disease between was July 1st- December 31st 2018. Patients who needed ECMO support at the first postoperative 72 hours were not included in the study group. The postoperative initial, 24th and 48th-hour Vasoactive-Inotrope Score (VIS) and VVR scores of all patients were calculated in the intensive care unit (ICU). The effects of these scores on lengthy ICU duration (PCILOS, duration more than the upper 25th percentile) and to the hospital mortality (before 30 days) were evaluated. RESULTS: There were 340 patients in this study. The median age was 12 months (1 day-18 years), and the median weight was 7 kg (2.5 -82 kg). 18% of the patients had single ventricle physiology. Total correction was performed in 88% of the patients. Median RACHS 1 score was 2 (1-6). PCILOS was>112 hours and total mortality was 4%. The 0th hour VVR ICU c index=0.73 (CI: 0.70-0.77), mortality c index=0.77 (CI: 0.69-0.85). VVR at 24th hour ICU c index=0.75 (CI: 0.71-0.79), mortality c index=0.86 (CI: 0.81-0.91). VVR at 48th-hour ICU c index=0.87 (CI: 0.82-0.92), mortality c index=0.92 (CI: 0.87-0.97). The VVR score at 48th-hour was a strong indicator for the prediction of both LICU duration (odds ratio [OR]: -1.44; p=0.001) and hospital mortality (OR: -1.28; p=0.001). CONCLUSION: The postoperative VVR score can be a strong determinant for the prediction of early clinical results in congenital heart disease patients, which were considerably a heterogeneous group.

RESUMO

OBJECTIVE: To evaluate surgical management and results of patients with pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries (PA/VSD/MAPCAs). METHODS: We reviewed a consecutive series of patients with PA/VSD/MAPCAs between January 2012 and October 2018. Study patients were separated into Group A, efficient MAPCAs; Group B, hypoplastic MAPCAs; Group C, severe hypoplastic MAPCAs at all divisions; and Group D, distal stenosis at most MAPCAs divisions. RESULTS: Thirty-six patients were included in the study. Median age at operation time was 5.5 months (2-110 months), median weight was 8 kg (2.5-21 kg), and median number of MAPCAs was three (1-6). In Group A, 14 patients underwent single-stage total correction (TC); in Group B, 18 patients underwent unifocalization and central shunting; and in Group C, four patients had aortopulmonary window creation and collateral ligation. No patient was placed in Group D. Seventy percent of patients (n=25) had the TC operation. Early mortality was not seen in Group A, but the other two groups had a 13.6% mortality rate. At the follow-up, three patients had reintervention, two had new conduit replacement, and one had right ventricular outflow tract reconstruction. CONCLUSION: Evaluating patients with PA/VSD/MAPCAs in detail and subdividing them is quite useful in determining the appropriate surgical approach. With this strategy, TC can be achieved in most patients. Single-stage TC is better than other surgical methods due to its lower mortality and reintervention rates. Care should be taken in terms of early postoperative intensive care complications and reintervention indications during follow-ups.

RESUMO

The standard treatment of transposition of the great arteries is the arterial switch operation (ASO). Despite successful surgical correction, patients cannot tolerate extubation after the operation. Major aortopulmonary collaterals (MAPCAs) are one of the rare causes of prolonged mechanical ventilation due to significant hemodynamic effects. We report a 28-day-old newborn with transposition of the great arteries and a ventricular septal defect (VSD) who underwent ASO and VSD closure. After postoperative extubation failed twice, four large MAPCAs were revealed during heart catheterization. After transcatheter closure of these four MAPCAs, the patient was extubated and discharged 27 days after the procedure.

RESUMO

OBJECTIVES: We aimed to compare the short- and midterm results of perfusion strategies used for arch reconstruction surgery. MATERIAL AND METHODS: One hundred and seventy-three consecutive patients who underwent aortic arch reconstruction surgery for transverse arcus hypoplasia between January 2011 and February 2020 were retrospectively analyzed. The patients were divided into two groups, as beating heart (BH) group and cardiac arrest (CA) group. RESULTS: The CA group comprised 60 (35%) patients and the remaining 113 (65%) patients were in the BH group. The median age of the patients was 30 (interquartile range: 18-95) days. The incidences of acute renal failure (ARF) and delayed sternal closure were higher in the CA group (p = .05, <.001, respectively). Balloon angioplasty was performed in 5 (2%) patients and reoperation was performed in 11 (6%) patients due to restenosis. There were no statistically significant differences between the two groups in terms of reoperation or reintervention rates (p = .44 and .34, respectively). CONCLUSIONS: Both strategies were associated with satisfactory midterm prevention of reintervention and reoperation. Given the lower incidence of ARF and delayed sternal closure in the postoperative period and similar midterm outcomes, we believe that the BH strategy is preferable.
