Recommendations for cardiovascular magnetic resonance and computed tomography in congenital heart disease: a consensus paper from the CMR/CCT Working Group of the Italian Society of Pediatric Cardiology and the Italian College of Cardiac Radiology endorsed by the Italian Society of Medical and Interventional Radiology (Part II).

Cardiovascular magnetic resonance (CMR) and computed tomography (CCT) are advanced imaging modalities that recently revolutionized the conventional diagnostic approach to congenital heart diseases (CHD), supporting echocardiography and often replacing cardiac catheterization. This is the second of two complementary documents, endorsed by experts from the Working Group of the Italian Society of Pediatric Cardiology and the Italian College of Cardiac Radiology of the Italian Society of Medical and Interventional Radiology, aimed at giving updated indications on the appropriate use of CMR and CCT in different clinical CHD settings, in both pediatrics and adults. In this article, support is also given to radiologists, pediatricians, cardiologists, and cardiac surgeons for indications and appropriateness criteria for CMR and CCT in the most referred CHD, following the proposed new criteria presented and discussed in the first document. This second document also examines the impact of devices and prostheses for CMR and CCT in CHD and additionally presents some indications for CMR and CCT exams when sedation or narcosis is needed.

The concept of cone creation to treat isolated tricuspid valve dysplasia and the case of a double-orifice tricuspid valve.

Objectives: Isolated tricuspid valve dysplasia is a rare disease characterized by a wide spectrum of possible anomalies. We describe the use of the Cone concept to treat a patient with a double-orifice tricuspid valve with massive regurgitation and severe deficit of coaptation. Methods: Three adult patients with congenital non-Ebstein tricuspid valve anomaly characterized by severe coaptation deficiency underwent tricuspid valve repair applying the Cone technique. In particular, we describe the case of a symptomatic 21-year-old woman with a double-orifice tricuspid valve, with massive regurgitation and severe right ventricular dilatation. The tricuspid valve was transformed from a double-orifice valve into a single-orifice valve. The most superior orifice was opened, and the tissue surrounding the orifice was used to extend the leaflet of the inferior orifice. A Cone was created, and a ring annuloplasty was used to stabilize the result. Results: The patient was discharged home after 7 days with trivial residual tricuspid regurgitation and no significant antegrade gradient. The final coaptation height was 2.8 cm. The cardiothoracic ratio decreased from 0.77 to 0.59 after 2 months, and symptoms promptly improved. Conclusions: Over the past 2 years, we have applied the Cone creation concept to patients with a severely dysplastic tricuspid valve with excellent early results. One patient had a double-orifice tricuspid valve, and a Cone repair concept was adopted anyway. One orifice was sacrificed, and surrounding tissue was used to augment the leaflets of the other orifice. A Cone was created to improve central coaptation with a good initial result.

Complete Isolation of Left Innominate Artery in a Patient With CHARGE Syndrome: Case Presentation and Review of Reported Cases.

We report a rare case of complete isolation of the left innominate artery in a child with CHARGE (coloboma, heart defects, atresia choanae, growth retardation, genital abnormalities, and ear abnormalities) syndrome. This anatomical cluster had been undetected for a relatively large period of time and the patient was referred to us with an incomplete diagnosis even after multiple medical evaluations and a thoracic surgery during the neonatal period. In conclusion, to the best of our knowledge, this is the first case of a complete isolation of left innominate artery treated with a transcatheter approach.

Long Term Follow-Up of Patients with Systemic Right Ventricle and Biventricular Physiology: A Single Centre Experience.

BACKGROUND: A progressively increasing prevalence of congenital heart disease (CHD) in adulthood has been noticed in recent decades; CHD cases with a systemic right ventricle have a poorer outcome. METHODS: Seventy-three patients with SRV evaluated in an outpatient clinic between 2014 and 2020 were enrolled in this study. Thirty-four patients had a transposition of the great arteries treated with an atrial switch operation; 39 patients had a congenitally corrected transposition of the great arteries (ccTGA). RESULTS: Mean age at the first evaluation was 29.6 ± 14.2 years; 48% of the patients were female. The NYHA class at the visit was III or IV in 14% of the cases. Thirteen patients had at least one previous pregnancy. In 25% of the cases, complications occurred during pregnancy. Survival free from adverse events was 98.6% at one year and 90% at 6-year follow-up without any difference between the two groups. Two patients died and one received heart transplantation during follow-up. The most common adverse event during follow-up was the presence of arrhythmia requiring hospitalization (27.1%), followed by heart failure (12.3%). The presence of LGE together with lower exercise capacity, higher NYHA class and more dilated and/or hypokinetic RV predicted a poorer outcome. Quality of life was similar to the QoL of the Italian population. CONCLUSIONS: Long-term follow-up of patients with a systemic right ventricle is characterized by a high incidence of clinical events, prevalently arrhythmias and heart failure, which cause most of the unscheduled hospitalizations.

Echocardiographic score to predict neonatal surgery for aortic coarctation in newborns with prenatal suspicion and patent ductus arteriosus.

INTRODUCTION: The evaluation of upcoming Aortic Coarctation (CoA) in new-borns with prenatal suspicion entails a close echocardiographic monitor until Arterial Duct (AD) closure, in a department with pediatric cardiological and surgical expertise. The significant number of false-positive prenatal diagnoses causes parental stress and healthcare costs. AIM: The aim of this study was to elaborate an echocardiographic prediction model to be employed at birth when PDA is still present, in patients suspected of CoA during fetal life in order to foretell CoA requiring neonatal surgical intervention. METHODS: This retrospective monocentric study included consecutive full-term and late preterm neonates with prenatal suspicion of CoA born from 01 January 2007 to 31 December 2020. Patients were divided into two groups according to the need for aortic surgery (CoA - NoCoA). All patients underwent a comprehensive transthoracic echocardiographic exam in presence of PDA. Multivariable logistic regression was used to create a coarctation probability model (CoMOD) including isthmal (D4), transverse arch (D3) diameters, the distance between a left common carotid artery (LCA) and left subclavian artery (LSA), presence/absence of ventricular septal defect (VSD) and bicuspid aortic valve (BAV). RESULTS: We enrolled 87 neonates (49 male, 56%). 44 patients developed CoA in need of surgical repair. Our index CoMOD showed an AUC = 0.9382, high sensitivity (91%) and specificity (86%) in the prediction of CoA in neonates with prenatal suspicion. We classified neonates with CoMOD > 0 to be at high risk for surgical correction of CoA, with good PPV (86.9%) and NPV (90.9%). CONCLUSIONS: CoMOD > 0 is highly suggestive of the need for CoA corrective surgery in newborns with prenatal suspicion.

Moderate and Severe Congenital Heart Diseases Adversely Affect the Growth of Children in Italy: A Retrospective Monocentric Study.

Children with congenital heart disease (CHD) are at increased risk for undernutrition. The aim of our study was to describe the growth parameters of Italian children with CHD compared to healthy children. We performed a cross-sectional study collecting the anthropometric data of pediatric patients with CHD and healthy controls. WHO and Italian z-scores for weight for age (WZ), length/height for age (HZ), weight for height (WHZ) and body mass index (BMIZ) were collected. A total of 657 patients (566 with CHD and 91 healthy controls) were enrolled: 255 had mild CHD, 223 had moderate CHD and 88 had severe CHD. Compared to CHD patients, healthy children were younger (age: 7.5 ± 5.4 vs. 5.6 ± 4.3 years, p = 0.0009), taller/longer (HZ: 0.14 ± 1.41 vs. 0.62 ± 1.20, p < 0.002) and heavier (WZ: -0,07 ± 1.32 vs. 0.31 ± 1.13, p = 0.009) with no significant differences in BMIZ (-0,14 ± 1.24 vs. -0.07 ± 1.13, p = 0.64) and WHZ (0.05 ± 1.47 vs. 0.43 ± 1.07, p = 0.1187). Moderate and severe CHD patients presented lower z-scores at any age, with a more remarkable difference in children younger than 2 years (WZ) and older than 5 years (HZ, WZ and BMIZ). Stunting and underweight were significantly more present in children affected by CHD (p < 0.01). In conclusion, CHD negatively affects the growth of children based on the severity of the disease, even in a high-income country, resulting in a significant percentage of undernutrition in this population.

Recommendations for cardiovascular magnetic resonance and computed tomography in congenital heart disease: a consensus paper from the CMR/CCT working group of the Italian Society of Pediatric Cardiology (SICP) and the Italian College of Cardiac Radiology endorsed by the Italian Society of Medical and Interventional Radiology (SIRM) Part I.

Cardiovascular magnetic resonance (CMR) and computed tomography (CCT) are advanced imaging modalities that recently revolutionized the conventional diagnostic approach to congenital heart diseases (CHD), supporting echocardiography and often replacing cardiac catheterization. Nevertheless, correct execution and interpretation require in-depth knowledge of all technical and clinical aspects of CHD, a careful assessment of risks and benefits before each exam, proper imaging protocols to maximize diagnostic information, minimizing harm. This position paper, written by experts from the Working Group of the Italian Society of Pediatric Cardiology and from the Italian College of Cardiac Radiology of the Italian Society of Medical and Interventional Radiology, is intended as a practical guide for applying CCT and CMR in children and adults with CHD, wishing to support Radiologists, Pediatricians, Cardiologists and Cardiac Surgeons in the multimodality diagnostic approach to these patients. The first part provides a review of the most relevant literature in the field, describes each modality's advantage and drawback, making considerations on the main applications, image quality, and safety issues. The second part focuses on clinical indications and appropriateness criteria for CMR and CCT, considering the level of CHD complexity, the clinical and logistic setting and the operator expertise.

Bentall Endocarditis by C. Lusitaniae After COVID-19: The Finger Covers The Moon.

We report a case of endocarditis months after a Bentall procedure. This was caused by Candida Lusitaniae, in an immunocompetent patient with a recent SARS-CoV-2 infection. The patient underwent a new Bentall procedure. SARS-CoV-2 has been associated with co-infection by Candida species since the beginning of the pandemic, nevertheless, Candida Lusitaniae remains a very uncommon causative agent of prosthetic endocarditis. We suggest a possible role of the SARS-CoV-2, which may have delayed the diagnosis of endocarditis and the appropriate therapy.

Fetal speckle-tracking echocardiography: a comparison between two-dimensional and electronic spatio-temporal image correlation (e-STIC) technique.

BACKGROUND: Speckle tracking technology has been applied to assess ventricular deformation throughout the cardiac cycle. An electronic four dimensional probe that allows rapid acquisition of electronic spatio-temporal image correlation volumes (eSTIC) has been recently introduced. OBJECTIVES: The aim of our study was to investigate whether e-STIC acquisition improves deformation analyses reproducibility. STUDY DESIGN: We recruited fetuses between 20 and 40 weeks of gestation. We obtained a 2D video clip and an e-STIC volume of a four-chamber view. We focused on left ventricular global strain (LV-GS) and left ventricular ejection fraction (LV-FE). Intraobserver, interobserver and intermethod agreement were assessed by means of intraclass correlation coefficient (ICC) and illustrated by Bland-Altman plots. Systematic differences between measurements were assessed using a paired t-test. RESULTS: The mean difference between LV-GS values obtained with e-STIC and 2D analysis was -0.10 (95% CI -2.28, 2.08). No systematic differences were found between the two techniques for LV-GS values (p-value = .927). The mean difference between LV-FE values obtained with e-STIC and 2D analysis was 7.55 (95% CI 4.16, 10.95; p-value <.001). The inter-rater reliability of LV-GS was moderate-to-substantial for both e-STIC and 2D. The inter-rater reliability of LV-FE obtained via e-STIC was superior to that obtained via 2D analysis. The intra-rater reliability of LV-GS obtained with e-STIC was superior to that obtained with 2D analysis (ICC 0.857; 95% IC 0.761-0.917). The intra-rater reliability of LV-FE obtained via e-STIC was superior to that obtained via 2D analysis (ICC 0.647; IC 0.51-0.783). CONCLUSIONS: e-STIC seems to be a better technique than 2D analysis for intra-rater reliability of LV-GS. 4D acquisition might improve intrinsic limitations of speckle tracking echocardiography.

Staged approach for correction of anomalous venous return to the azygos vein.

Partial anomalous pulmonary venous return into the azygous vein is a rare pathological finding. We describe the case of a 28-year-old girl who had a successful staged approach to treat this rare congenital heart disease. To avoid potential connection of a systemic venous return to the left atrium, the proximal part of the azygous vein was occluded with a percutaneous approach, then the azygous vein flow was redirected into the left atrium with a surgical procedure.

Study design and rationale of the pAtients pResenTing with cOngenital heaRt dIseAse Register (ARTORIA-R).

AIM: Due to improved therapy in childhood, many patients with congenital heart disease reach adulthood and are termed adults with congenital heart disease (ACHD). ACHD often develop heart failure (HF) as a consequence of initial palliative surgery or complex anatomy and subsequently require advanced HF therapy. ACHD are usually excluded from trials evaluating heart failure therapies, and in this context, more data about heart failure trajectories in ACHD are needed to guide the management of ACHD suffering from HF. METHODS AND RESULTS: The pAtients pResenTing with cOngenital heaRt dIseAse Register (ARTORIA-R) will collect data from ACHD evaluated or listed for heart or heart-combined organ transplantation from 16 countries in Europe and the Asia/Pacific region. We plan retrospective collection of data from 1989-2020 and will include patients prospectively. Additional organizations and hospitals in charge of transplantation of ACHD will be asked in the future to contribute data to the register. The primary outcome is the combined endpoint of delisting due to clinical worsening or death on the waiting list. The secondary outcome is delisting due to clinical improvement while on the waiting list. All-cause mortality following transplantation will also be assessed. The data will be entered into an electronic database with access to the investigators participating in the register. All variables of the register reflect key components important for listing of the patients or assessing current HF treatment. CONCLUSION: The ARTORIA-R will provide robust information on current management and outcomes of adults with congenital heart disease suffering from advanced heart failure.

Transcatheter Closure of PFO and ASD: Multimodality Imaging for Patient Selection and Perioperative Guidance.

Transcatheter closure of patent foramen ovale (PFO) and secundum type atrial septal defect (ASD) are common transcatheter procedures. Although they share many technical details, these procedures are targeting two different clinical indications. PFO closure is usually considered to prevent recurrent embolic stroke/systemic arterial embolization, ASD closure is indicated in patients with large left-to-right shunt, right ventricular volume overload, and normal pulmonary vascular resistance. Multimodality imaging plays a key role for patient selection, periprocedural monitoring, and follow-up surveillance. In addition to routine cardiovascular examinations, advanced neuroimaging studies, transcranial-Doppler, and interventional transesophageal echocardiography/intracardiac echocardiography are now increasingly used to deliver safely and effectively such procedures. Long-standing collaboration between interventional cardiologist, neuroradiologist, and cardiac imager is essential and it requires a standardized approach to image acquisition and interpretation. Periprocedural monitoring should be performed by experienced operators with deep understanding of technical details of transcatheter intervention. This review summarizes the specific role of different imaging modalities for PFO and ASD transcatheter closure, describing important pre-procedural and intra-procedural details and providing examples of procedural pitfall and complications.

Prenatal sonography of the foramen ovale predicts urgent balloon atrial septostomy in neonates with complete transposition of the great arteries.

BACKGROUND: Hypoxia caused by inadequate intracardiac mixing owing to a restrictive foramen ovale is a potentially life-threatening complication in neonates with dextro-transposition of the great arteries. An urgent balloon atrial septostomy is a procedure of choice in such cases, but dependent on the availability of a 24-hour interventional cardiology facility. The prenatal identification of predictors for an urgent balloon atrial septostomy at birth would help in optimizing the management of these neonates, minimizing the risk of hypoxic damage. OBJECTIVE: This study aimed to predict with prenatal echocardiography the need of urgent balloon atrial septostomy in neonates with dextro-transposition of the great arteries. STUDY DESIGN: This was a retrospective cohort study of patients with a prenatal diagnosis of transposition of the great arteries that were delivered in our center between 2010 and 2019, for whom fetal ultrasound echocardiograms obtained at less than 3 weeks before delivery were available. The following parameters were systematically obtained at fetal echocardiography: size and appearance of the foramen ovale, septum primum excursion (foramen ovale flap angle at the maximal excursion), diameters of the atria, and size of the ductus arteriosus. Balloon atrial septostomy was defined as urgent if performed within 12 hours from birth in neonates with restrictive foramen ovale. Neonatal follow-up was obtained through medical records analysis. RESULTS: From November 2007 to April 2019, 160 fetuses with complete transposition of the great arteries were referred to our echocardiography laboratory and 60 of these were included in the analysis; 27 underwent urgent balloon atrial septostomy, 11 elective balloon atrial septostomy, and 22 no balloon atrial septostomy. The size of the foramen ovale was the best predictor of an urgent balloon atrial septostomy. A measurement of >6.5 mm had a sensitivity of 100% and a false positive rate of 45%. CONCLUSION: Fetal echocardiography predicts the need of an urgent balloon atrial septostomy in fetuses with dextro-transposition of the great arteries although with a limited precision. In our experience, a measurement of the foramen ovale within 3 weeks of delivery had the greatest accuracy.

Coronary Artery Aneurysms in Patients With Marfan Syndrome: Frequent, Progressive, and Relevant.

BACKGROUND: There are few data on the prevalence and clinical consequences of coronary artery aneurysms (CAAs) in adult patients with Marfan syndrome (MFS). METHODS: We performed a retrospective cohort study of 109 patients with pathogenic variants in the FBN1 gene. Diameters of the left main coronary artery (LMCA) and right- coronary artery (RCA) were measured by computed tomography angiography. RESULTS: The overall prevalence of CAA was 46%. The prevalence rates of CAA were 18% and 68% in patients with a native aortic root (group 1) and patients with previous aortic-root replacement (group 2), respectively. Previous aortic dissection or aortic intervention, longer time from aortic-root replacement, higher systemic score, significant mitral valve involvement, and diffuse aortic disease were correlated with CAA. During a mean follow-up of 8.5 ± 7.6 years, 4 patients developed pseudoaneurysms of the coronary anastomoses, requiring surgery. CONCLUSIONS: CAAs are common in adult patients with MFS and are associated with a more severe aortic phenotype and a longer follow-up after aortic-root replacement. Our study demonstrates that coronary artery size should be regularly followed, mostly after aortic-root replacement and in patients with severe aortic phenotypes. Large multicentre studies are warranted to elucidate the most appropriate surveillance plan.

Ductal ligation timing and neonatal outcomes: a 12-year bicentric comparison.

Patent ductus arteriosus (PDA) is common among extremely preterm infants. In selected cases, surgical PDA ligation may be required. The timing for PDA ligation may depend upon a variety of factors, with potential clinical implications. We aimed to investigate the impact of different surgical PDA managements on ligation timing and neonatal outcomes. Inborn infants < 32 weeks of gestation and < 1500 g admitted at two tertiary Neonatal Intensive Care Units that underwent PDA ligation between 2007 and 2018 were enrolled in this retrospective cohort study and split into the following groups based on their surgical management: on-site bedside PDA ligation (ONS) vs. referral to an off-site pediatric cardiac surgery (OFS). Neonatal characteristics, surgical timing, and clinical outcomes of the enrolled infants were compared between the groups. Multivariate analysis was performed to evaluate the impact of PDA ligation timing on significantly different outcomes. Seventy-eight neonates (ONS, n = 39; OFS, n = 39) were included. Infants in the ONS group underwent PDA ligation significantly earlier than those in the OFS group (median age 12 vs. 36 days, p < 0.001) with no increase in postoperative mortality and complications. The multivariate analysis revealed a significant association between PDA ligation timing, late-onset sepsis prevalence (OR 1.045, 0.032), and oxygen need at discharge (OR 1.037, p = 0.025).Conclusions: Compared with off-site surgery, on-site bedside ligation allows an earlier surgical closure of PDA, with no apparent increase in mortality or complications. Earlier PDA ligation may contribute to reduced rates of late-onset sepsis and post-discharge home oxygen therapy, with possible cost-benefit implications. What is known: • Ineffective or contraindicated pharmacological closure of a hemodynamically significant PDA may require a surgical ligation. • Available literature comparing the effect of early vs. late PDA ligation on the main neonatal morbidities has yield contrasting results. What is new: • The availability of a cardiac surgery service performing bedside PDA ligation allows an earlier intervention compared to patient referral to an off-site center, with no difference in postoperative mortality and complications compared to off-site surgery. • Earlier PDA ligation was associated with a lower prevalence of late-onset sepsis and of oxygen need at discharge, with possible cost-benefit implications.

Myocardial oxygen consumption during histidine-tryptophan-ketoglutarate cardioplegia in young human hearts.

OBJECTIVES: Energy demand and supply need to be balanced to preserve myocardial function during paediatric cardiac surgery. After a latent aerobic period, cardiac cells try to maintain energy production by anaerobic metabolism and by extracting oxygen from the given cardioplegic solution. Myocardial oxygen consumption (MVO2) changes gradually during the administration of cardioplegia. METHODS: MVO2 was measured during cardioplegic perfusion in patients younger than 6 months of age (group N: neonates; group I: infants), with a body weight less than 10 kg. Histidine-tryptophan-ketoglutarate crystalloid solution was used for myocardial protection and was administered during a 5-min interval. To measure pO2 values during cardioplegic arrest, a sample of the cardioplegic fluid was taken from the inflow line before infusion. Three fluid samples were taken from the coronary venous effluent 1, 3 and 5 min after the onset of cardioplegia administration. MVO2 was calculated using the Fick principle. RESULTS: The mean age of group N was 0.2 ± 0.09 versus 4.5 ± 1.1 months in group I. The mean weight was 3.1 ± 0.2 versus 5.7 ± 1.6 kg, respectively. MVO2 decreased similarly in both groups (min 1: 0.16 ± 0.07 vs 0.36 ± 0.1 ml/min; min 3: 0.08 ± 0.04 vs 0.17 ± 0.09 ml/min; min 5: 0.05 ± 0.04 vs 0.07 ± 0.05 ml/min). CONCLUSIONS: We studied MVO2 alterations after aortic cross-clamping and during delivery of cardioplegia in neonates and infants undergoing cardiac surgery. Extended cardioplegic perfusion significantly reduces energy turnover in hearts because the balance procedures are both volume- and above all time-dependent. A reduction in MVO2 indicates the necessity of a prolonged cardioplegic perfusion time to achieve optimized myocardial protection.

Prenatal diagnosis of congenital heart defects and voluntary termination of pregnancy.

BACKGROUND: The prenatal diagnosis of an isolated congenital heart defect is a matter of concern for parents. The decision of whether to terminate the pregnancy according to the different types of congenital heart defects has not been investigated yet. OBJECTIVE: This study aimed to evaluate the frequency of voluntary termination of pregnancy after the prenatal diagnosis of a congenital heart defect in a tertiary care center. STUDY DESIGN: This was a retrospective study of patients who were referred to our center from January 2013 to December 2019, underwent fetal echocardiography, and were counseled by a perinatologist and a pediatric cardiologist. The following data were collected: prenatal diagnosis, including genetic testing; gestational age at diagnosis; and outcome of pregnancy. The diagnoses were stratified retrospectively according to the type of congenital heart defect and its severity (low complexity, moderate complexity, and high complexity) by a perinatologist and a pediatric cardiologist. RESULTS: Of 704 women who received a diagnosis of fetal congenital heart defect, 531 (75.4%) were seen before 23 weeks' gestation, which is the upper limit imposed for the termination of pregnancy by the Italian legislation. Congenital heart defects were apparently isolated in 437 of 531 cases (82.3%). Overall, 108 of 531 patients (20.3%) requested a termination of pregnancy. The rate of termination of pregnancy was found to vary according to the severity of congenital heart defects: low complexity, 0%; moderate complexity, 12.1%, and high complexity, 33.2% (P<.001). The presence or absence of associated anomalies or the ethnicity of the couples was not found to have an influence on women's decisions. CONCLUSION: In our population, the decision to terminate a pregnancy after the diagnosis of a fetal congenital heart defect is influenced by the surgical complexity of the congenital heart defect itself. However, most patients, including those with the most severe forms of congenital heart defect, decided to continue the pregnancy.

[Modified Warden procedure for correction of right superior vena cava drainage in the left atrium]. / Warden modificata per la correzione del drenaggio anomalo della vena cava superiore in atrio sinistro.

A newborn with situs solitus, normally related great arteries and intact atrial septum, underwent surgical repair at our institution for anomalous drainage of the right superior vena cava in the left atrium at the level of the right superior pulmonary veins. This rare cyanotic congenital cardiac malformation is herein described with special regard to its anatomical and diagnostic features. A novel surgical approach for achieving correction is also described.

Aortopulmonary Collateral Artery from the Proximal Ascending Aorta: A Rare Anatomical Finding.

Tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries is a rare congenital heart lesion in which pulmonary blood supply may arise from different segments of the aorta. We report an unusual case of a newborn with a major collateral artery originating from the proximal ascending aorta. Successful reparative surgery was undertaken.
