Coarctation of the aorta complicated with bilateral iliac artery dissection: A rare case.

The coarctation of the aorta (CoA) combined with heart defects or cerebral artery aneurysms is more prevalent in clinical practice. However, cases of concurrent bilateral iliac artery dissection (IAD) are extremely rare and have not been reported. Here, we described a case with CoA combined with bilateral IAD. The patient, a 62-year-old male, presented with acute intermittent claudication accompanied by pain and aching in both lower limbs after walking. Following a thorough medical history inquiry and examination, the patient was diagnosed with acute bilateral IAD combined with CoA. The patient underwent endovascular treatment. Postoperatively, the aortic diameter recovered, and the bilateral IAD disappeared, yielding satisfactory therapeutic results. Conclusively, endovascular treatment of aortic coarctation combined with IAD is an effective therapeutic approach, enhancing patient survival and improving their quality of life.

Review of speckle tracking analysis to measure the size, shape, and contractility of the fetal heart in fetuses with congenital heart defects.

Evaluation of the fetal heart involves two approaches. The first describes a screening protocol in which the heart is imaged in transverse planes that includes the four-chamber view (4CV), left and right outflow tracts, and the 3-vessel-tracheal view. The second approach is a fetal echocardiogram that requires additional cardiac images as well as evaluating ventricular function using diagnostic tools such as M-mode and pulsed Doppler ultrasound. Speckle tracking analysis of the ventricular and atrial endocardium of the fetal heart has focused primarily on computing longitudinal global strain. However, the technology enabling this measurement to occur has recently been adapted to enable the clinician to obtain numerous additional measurements of the size, shape, and contractility of the ventricles and atrial chambers. By using the increased number of measurements derived from speckle tracking analysis, we have reported the ability to screen for tetralogy of Fallot, D-transposition of the great arteries (D-TGA), and coarctation of the aorta by only imaging the 4CV. In addition, we have found that measurements derived from speckle tracking analysis of the ventricular and atrial chambers can be used to compute the risk for emergent neonatal balloon atrial septostomy in fetuses with D-TGA. The purpose of this review is to consolidate our experience in one source to provide perspective on the benefits of speckle tracking analysis to measure the size, shape, and contractility of the ventricles and atria imaged in the 4CV in fetuses with congenital heart defects.

Partial cardiopulmonary bypass through left thoracotomy for coarctation repair in children.

BACKGROUND: A left thoracotomy approach is anatomically appropriate for childhood aortic coarctation; however, the pediatric femoral arteriovenous diameters are too small for cardiopulmonary bypass cannulation. We aimed to determine the safety of a partial cardiopulmonary bypass through the main pulmonary artery and the descending aorta in pediatric aortic coarctation repair. METHODS: We retrospectively reviewed 10 patients who underwent coarctation repair under partial main pulmonary artery-to-descending aorta cardiopulmonary bypass with a left thoracotomy as the CPB group. During the same period, 16 cases of simple coarctation of the aorta repair, with end-to-end anastomosis through a left thoracotomy without partial CPB assistance, were included as the non-CPB group to evaluate the impact of partial CPB. RESULTS: The median age and weight at surgery of the CPB group were 3.1 years (range, 9 days to 17.9 years) and 14.0 (range, 2.8-40.7) kg, respectively. Indications for the partial cardiopulmonary bypass with overlap were as follows: age > 1 year (n = 7), mild aortic coarctation (n = 3), and predicted ischemic time > 30 min (n = 5). Coarctation repair using autologous tissue was performed in seven cases and graft replacement in three. The mean partial cardiopulmonary bypass time, descending aortic clamp time, and cardiopulmonary bypass flow rate were 73 ± 37 min, 57 ± 27 min, and 1.6 ± 0.2 L/min/m2, respectively. Urine output during descending aortic clamping was observed in most cases in the CPB group (mean: 9.1 ± 7.9 mL/kg/h), and the total intraoperative urine output was 3.2 ± 2.7 mL/kg/h and 1.2 ± 1.5 mL/kg/h in the CPB and non-CPB group, respectively (p = 0.020). The median ventilation time was 1 day (range, 0-15), and the intensive care unit stay duration was 4 days (range, 1-16) with no surgical deaths. No major complications, including paraplegia or recurrent coarctation, occurred postoperatively during a median observation period of 8.1 (range, 3.4-17.5) years in the CPB group. In contrast, reoperation with recurrent coarctation was observed in 2 cases in the non-CPB group (p = 0.37). CONCLUSIONS: Partial cardiopulmonary bypass through the main pulmonary artery and descending aorta via a left thoracotomy is a safe and useful option for aortic coarctation repair in children.

Influence of Aortic Arch Morphology on Renal Perfusion in Patients with Coarctation of the Aorta: An Exploratory Study.

Objectives: The configuration of the aortic arch, particularly a Gothic arch shape, in individuals with corrected coarctation of the aorta (CoA) has been associated with a decreased systolic wave amplitude across the arch, which could potentially impair renal perfusion and elevate the risk of arterial hypertension. This study aims to explore the relationship between the morphological characteristics of the aortic arch and their impact on renal perfusion in patients with CoA. Methods: Seventy-one subjects with corrected CoA underwent continuous 24 h ambulatory blood pressure monitoring, computed tomography to assess the aortic arch, and renal perfusion scanning. Subjects were stratified into three groups based on the height-to-width (H/W) ratio of their aortic arch: Group 1 with a H/W ratio of <0.65, Group 2 with a H/W ratio between 0.65 and 0.85, and Group 3 with a H/W ratio of >0.85. Results: Groups 1 and 2 (53,78% and 62.63%) presented with a higher hypertension prevalence of elevated blood pressure than Group 3 (38.89%). Notable variations were observed among the subjects in the time to peak perfusion (Tmax) in the left kidney across the groups. Group 1 showed a median Tmax at 0.27, Group 2 at 0.13, and Group 3 at -0.38 (p-value = 0.079). The differences in Tmax for the right kidney followed a similar trend but were not statistically significant (Group 1 at 0.61, Group 2 at 0.22, and Group 3 at 0.11; p-value = 0.229). Conclusions: This study suggests that variations in the aortic arch morphology might not significantly influence renal perfusion in CoA patients. This indicates the potential adaptability of the renal blood flow, which appears to compensate for reduced perfusion, thus minimizing adverse effects on the kidney function. This adaptability suggests an inherent physiological resilience, emphasizing the need for further targeted research to understand the specific interactions and impacts on treatment strategies for CoA.

Post-ductal coarctation of aorta aneurysm repair in adult via left antero-axillary thoracotomy with antegrade cerebral perfusion-a case series.

Coarctation of the aorta is a common congenital abnormality that may be associated with serious and rare anomalies like aneurysms. Severe coarctation or interrupted aortic arch in adults is usually managed by percutaneous interventions or extra-anatomic bypass. However, the presence of an aneurysm beyond the coarcted segment implies the opening of a collateral-rich segment of the aorta with redressal of the arch if hypoplastic. We describe our experience in managing three such patients through antero-lateral thoracotomy with antegrade cerebral perfusion. We have found this technique helpful in treating aneurysms of the distal aortic arch or proximal descending thoracic aorta.

Against all odds: successful pregnancy in an adult patient with unrepaired coarctation of the aorta.

According to the modified World Health Organization classification, pregnant women with unrepaired aortic coarctation are at very high risk for both maternal and fetal complications and should, therefore, be counselled against pregnancy. The most frequent maternal complications include systemic hypertension, renal failure, preeclampsia, and aortic dissection. Herein, we describe a successful pregnancy in an adult patient with unrepaired aortic coarctation.

Bilateral Ductus Arteriosus With Anomalous Origin of the Right Pulmonary Artery and Coarctation of the Aorta.

We present a full-term neonate with a postnatal diagnosis with a left aortic arch, bilateral ducti, and discontinuous branch pulmonary arteries with right pulmonary artery arising from right duct. Upon left ductal constriction, the patient experienced coarctation of the aorta, illustrating the importance of careful and serial interrogation of rare cardiac anatomy.

Health-related quality of life among paediatric patients with coarctation of the aorta: an observational study.

Advancements in early diagnosis and paediatric cardiac surgery have improved the long-term survival of patients with congenital heart disease, necessitating a thorough assessment of their health-related quality of life (HRQoL). This study aimed to assess HRQoL in paediatric patients with coarctation of the aorta (CoA) (both as reported by patients and caregivers), and to evaluate associated factors. Patients aged 5-18 years diagnosed with CoA and their parents were enrolled at Bambino Gesù Children's Hospital between September 2016 and December 2017. Socio-demographic characteristics were recorded using a family form, and the Pediatric Quality of Life Inventory (PedsQL) 3.0 cardiac module was used to evaluate HRQoL. Clinical data were retrieved from medical chart reviews. In this observational study, sixty-five pediatric patients (39 males, median [IQR] age 12 [9-14]) with CoA and their parents (65 mothers and 65 fathers) were enrolled. These patients exhibited overall good HRQoL. Mothers reported significantly lower total HRQoL scores compared to patient self-reports (p = .037), as well as treatment anxiety (p = .033), and cognitive problems (p = .021). Pediatric patients with CoA perceived their HRQoL better than their mothers did. Female sex and older age were associated with lower HRQoL scores.

Effect of Dexmedetomidine on Incidence of Hypertension Following Repair of Coarctation of the Aorta.

OBJECTIVE: Recent literature suggests a potential role for dexmedetomidine in reducing the incidence and severity of hypertension following repair of coarctation of the aorta (CoA). The primary aim of this study was to assess the association between dexmedetomidine use and the incidence of hypertension following repair of CoA in pediatric patients. METHODS: This was a single-center, retrospective cohort study in patients younger than 19 years who underwent surgical repair of CoA between January 1, 2016, and September 30, 2021. Patients were divided into 2 groups: dexmedetomidine initiation within the first 3 hours after surgery or no dexmedetomidine. The primary outcome was incidence of hypertension within the first 4 to 24 hours after repair. Secondary outcomes included the incidence of hypotension and bradycardia. RESULTS: A total of 80 patients were included, 25 (31.25%) received dexmedetomidine. Median age at the time of procedure was 26 days (IQR, 13-241) in the dexmedetomidine group and 14 days (IQR, 8-53) in the no dexmedetomidine group (p = 0.014). The primary outcome of hypertension was met in 7 patients (28%) in the dexmedetomidine group and 12 patients (21.8%) in the no dexmedetomidine group, p = 0.547. The only variable found to be associated with the incidence of hypertension was age greater than 30 days at the time of procedure. More patients who received dexmedetomidine experienced bradycardia. There was no difference in the incidence of hypotension. CONCLUSIONS: There was no association between the use of dexmedetomidine and the incidence of -hypertension following repair of CoA in pediatric patients.

15-Year Analysis of Surgical Approaches and Outcomes for Coarctation in 132 Neonates and Infants.

A variety of surgical approaches exist to treat aortic coarctation in neonates and infants. Our institutional approach is designed to match the surgical approach to the individual anatomy of the patient. The objective of this study is to evaluate operative characteristics and outcomes of all neonates and infants who underwent surgical repair of coarctation of the aorta or hypoplastic aortic arch at University of Florida from 2006 to 2021, inclusive, either in isolation or with concomitant repair of atrial septal defect (ASD) and/or ventricular septal defect (VSD). A retrospective review was performed of 132 patients aged 0-1 year who underwent surgical repair of aortic coarctation or hypoplastic aortic arch between 2006 and 2021, inclusive, either in isolation or with concomitant repair of ASD and/or VSD. Patients were divided into two groups based on the surgical approach: Group 1 = Median Sternotomy and Group 2 = Left Lateral Thoracotomy. Continuous variables are presented as median (minimum-maximum); categorical variables are presented as N (%). The most common operative technique in Group 1 was end-to-side reconstruction with ligation of the aortic isthmus. The most common operative technique in Group 2 was extended end-to-end repair. Operative Mortality was one patient (1/132 = 0.76%). Transcatheter intervention for recurrent coarctation was performed in seven patients (7/132 = 5.3%). Surgical re-intervention for recurrent coarctation was performed in three patients (3/132 = 2.3%). From these data, one can conclude that a strategy of matching the surgical approach to the anatomy of neonates and infants who underwent surgical repair of aortic coarctation or hypoplastic aortic arch, either in isolation or with concomitant repair of ASD and/or VSD, is associated with less than 1% Operative Mortality and less than 3% recurrent coarctation requiring reoperation.

Sudden death in adults with repaired coarctation of the aorta: A case for sex-based risk factors.

Background: Sudden cardiac death (SCD) is an important risk for adults with repaired coarctation of the aorta (rCoA). We aimed determine if there are clinical risk factors for SCD in adults with rCoA. Methods and results: SCD events and clinical data from all adults with rCoA at a tertiary care center (2007-2017) were evaluated. In 167 adults with rCoA (39 ± 11 years old, 75 (45%) female) SCD occurred in 8 (5%) (vs. age-matched adults 0.9%). Those with SCD demonstrated significant QTc prolongation (QTc: 479 ± 16 vs. 434 ± 30 msec, p < 0.001). Overall, adults with rCoA and a prolonged sex-normative QTc interval had a 12-fold increased risk of SCD (x2 (1) = 12.3, p < 0.001), with men sustaining SCD at younger ages (42 ± 13 years vs. women 60 ± 10 years, p < 0.05). Multiple logistic regression modeling demonstrated that prolonged QTc selectively advanced risk for SCD in men only (x2 QTc prolongation 8.46, p < 0.005 and x2 age 0.29, p = 0.587), whereas in women, age was associated with SCD risk (x2 QTc prolongation 2.84, p = 0.092 and x2 age 7.81, p = 0.005). Non-sustained ventricular tachycardia, ventricular dysfunction, and myocardial fibrosis did not significantly impact SCD risk. Conclusions: There is an unanticipated high burden of SCD in adults with rCoA, occurring in men at younger age than women, suspicious for primary electrophysiologic dysfunction. Future investigation of sex-specific SCD risk in rCoA is important to better understand this disease and its late phenotype.

The role of 3D technology in the practical education of congenital coarctation and its treatment-a feasibility pilot study.

BACKGROUND: Coarctation of the aorta (CoA) is a congenital disease with an incidence of 4 out of 10,000 live births, therefore proper education of its treatment is essential. Understanding the disease and the wide array of treatment options is often difficult. Additive manufacturing technology can be used to produce 3D printed hands-on surgical training tools (HOSTT), which can be used for the education and practical training of CoA. This study aimed to investigate the effectiveness of a 3D printable HOSTT for the simulation of coarctation surgery, and it' possible role in practical education. METHODS: Participants were medical students of Semmelweis University between the second and sixth academic year. A virtual 3D model of an aorta with CoA was generated from a computed tomography angiography scan. Each participant received a 3D-printed aorta phantom and performed either one of four surgical treatment modalities. The simulated surgeries included end-to-end anastomosis, end-to-side anastomosis, prosthetic patch, and subclavian flap aortoplasty. Participants provided feedback, evaluating their understanding of the disease and its treatment by the four surgical reconstruction modalities on a seven-point Likert scale before and after the sessions. RESULTS: 21 medical students participated in this study. Participants' average rating of their understanding of CoA disease and it treatment options before practical training was 4.62 ± 1.07. After training, their average rating increased to 6.19 ± 1.08, showing statistically significant difference. CONCLUSIONS: Within this study's limitations, the applied HOSTT, manufactured using 3D printing, was effective for the practical training of CoA's surgical treatment methods for medical students.

Association of Prenatally Diagnosed Isolated Single Left Superior Vena Cava and Postnatal Development of Coarctation of the Aorta.

To report the prevalence of coarctation of the aorta (CoA) in fetuses with single left superior vena cava (SL-SVC) and to evaluate changes in echocardiographic measurements. Additionally, to report the prevalence of associated malformations. Retrospective observational study of fetuses diagnosed with SL-SVC between 2012 and 2021 at a tertiary fetal cardiology unit. In fetuses without intracardiac abnormalities, Z-scores of the ventricles, great arteries, and Doppler flow patterns are reported. We identified 47 fetuses with SL-SVC of which 8/47 (17%) had abnormal intracardiac anatomy. One fetus was lost to follow-up. Of those with normal intracardiac anatomy and postnatal follow-up (38), karyotype abnormalities were confirmed in 2/38 (5%) and ECA in 8/38 (21%). 33/38 were live-born. None developed CoA postnatally. Paired analysis of Z-scores between early and late scans of 24 fetuses showed that diameters of the right heart structures and Doppler flows of tricuspid valve increased significantly during pregnancy, while the left heart structures and flow patterns did not change. The median risk of CoA did not change between the early and the late scan. We did not observe CoA in this cohort. A degree of ventricular asymmetry was present, but this was due to right heart dominance rather than hypoplasia of left heart structures. This likely reflects redistribution of blood and does not appear to confer increased risk of CoA. Predictive models of the postnatal development of CoA which set the dimensions of right and left heart structures in relation might not be applicable in this situation.

Un-diagnosed coarctation of the aorta in a 27-year-old adult with a rare presentation: a rare case report.

Introduction and importance: Coarctation of the aorta (COA) is a rare form of congenital heart disease that is typically diagnosed in children. COA is known to present with hypertension, weak or absent femoral pulses, heart failure in older patients, but the presentation of COA as calf atrophy is extremely rare. This article reports the successful surgical repair of a 27-year-old adult with undiagnosed COA. Case presentation: A 27-year-old-male has presented with calf atrophy, which was diagnosed as COA transthoracic echocardiography and computed tomography angiography indicate COA, which is treated with successful surgical repair. Clinical discussion: COA is typically diagnosed in children with a rare incidence in adults. Calf atrophy is an extremely rare presentation and uncommon. He has calf atrophy, which led to the diagnosis of COA in 27 years. The presentation in this medium-aged population with this rare manifestation gives our case significance to be one of the unique reported cases. Conclusion: COA is uncommon to be found in adults and the presentation with calf atrophy is even rare. The authors revealed that COA can be found in adults and with an unexpected manifestation and highlights the significance of early detection, and timely referral to a specialist can enable proper management, which includes surgical correction.

Diagnostic accuracy of prenatal ultrasound in coarctation of aorta: systematic review and individual participant data meta-analysis.

OBJECTIVE: To determine the diagnostic accuracy of prenatal ultrasound in detecting coarctation of the aorta (CoA). METHODS: An individual participant data meta-analysis was performed to report on the strength of association and diagnostic accuracy of different ultrasound signs in detecting CoA prenatally. MEDLINE, EMBASE and CINAHL were searched for studies published between January 2000 and November 2021. Inclusion criteria were fetuses with suspected isolated CoA, defined as ventricular and/or great vessel disproportion with right dominance on ultrasound assessment. Individual participant-level data were obtained by two leading teams. PRISMA-IPD and PRISMA-DTA guidelines were used for extracting data, and the QUADAS-2 tool was used for assessing quality and applicability. The reference standard was CoA, defined as narrowing of the aortic arch, diagnosed after birth. The most commonly evaluated parameters on ultrasound, both in B-mode and on Doppler, constituted the index test. Summary estimates of sensitivity, specificity, diagnostic odds ratio (DOR) and likelihood ratios were computed using the hierarchical summary receiver-operating-characteristics model. RESULTS: The initial search yielded 72 studies, of which 25 met the inclusion criteria. Seventeen studies (640 fetuses) were included. On random-effects logistic regression analysis, tricuspid valve/mitral valve diameter ratio > 1.4 and > 1.6, aortic isthmus/arterial duct diameter ratio < 0.7, hypoplastic aortic arch (all P < 0.001), aortic isthmus diameter Z-score of < -2 in the sagittal (P = 0.003) and three-vessel-and-trachea (P < 0.001) views, pulmonary artery/ascending aorta diameter ratio > 1.4 (P = 0.048) and bidirectional flow at the foramen ovale (P = 0.012) were independently associated with CoA. Redundant foramen ovale was inversely associated with CoA (P = 0.037). Regarding diagnostic accuracy, tricuspid valve/mitral valve diameter ratio > 1.4 had a sensitivity of 72.6% (95% CI, 48.2-88.3%), specificity of 65.4% (95% CI, 46.9-80.2%) and DOR of 5.02 (95% CI, 1.82-13.9). The sensitivity and specificity values were, respectively, 75.0% (95% CI, 61.1-86.0%) and 39.7% (95% CI, 27.0-53.4%) for pulmonary artery/ascending aorta diameter ratio > 1.4, 47.8% (95% CI, 14.6-83.0%) and 87.6% (95% CI, 27.3-99.3%) for aortic isthmus diameter Z-score of < -2 in the sagittal view and 74.1% (95% CI, 58.0-85.6%) and 62.0% (95% CI, 41.6-78.9%) for aortic isthmus diameter Z-score of < -2 in the three-vessel-and-trachea view. Hypoplastic aortic arch had a sensitivity of 70.0% (95% CI, 42.0-88.6%), specificity of 91.3% (95% CI, 78.6-96.8%) and DOR of 24.9 (95% CI, 6.18-100). The diagnostic yield of prenatal ultrasound in detecting CoA did not change significantly when considering multiple categorical parameters. Five of the 11 evaluated continuous parameters were independently associated with CoA (all P < 0.001) but all had low-to-moderate diagnostic yield. CONCLUSIONS: Several prenatal ultrasound parameters are associated with an increased risk for postnatal CoA. However, diagnostic accuracy is only moderate, even when combinations of parameters are considered. © 2024 The Authors.

Type A Aortic Dissection in a 24-Year-Old Patient With Kabuki Syndrome.

Our case report documents the first type A aortic dissection in a patient with Kabuki syndrome (KS) and emphasize the need for intensive cardiovascular risk monitoring in patients with KS. It stresses the importance of further research to establish a correlation and awareness for patients with KS.

Left Ventricular Vortex Characteristics in Fetuses With Coarctation of the Aorta by Blood Speckle-Tracking Echocardiography.

OBJECTIVES: The aims of this study were to assess the vortex characteristics of left ventricle (LV) in fetuses with coarctation of the aorta (CoA) using high-frame rate ultrasound with blood speckle-tracking (BST) and explore its relationships with cardiac function and morphology parameters. METHODS: Thirty fetuses with CoA and 30 gestational-age matched normal fetuses were included in this cross-sectional study. The area, length, width, and position of the vortex in the LV were recorded and quantitatively analyzed by BST echocardiography. The associations of vortex properties with ventricular function and morphology were also determined. RESULTS: Based on BST imaging, the LV vortex can be observed in 93% of the fetuses. The fetuses with CoA exhibited significantly larger and wider vortex than the controls (P < .05). Linear regression analysis indicated that vortex area was positively related to sphericity index of LV as well as isovolumic relaxation time (r = .52, P = .003 and r = .42, P = .021). There was a negative correlation between vortex area and mitral valve size (r = -.443, P = .014). No significant association was found between vortex area and myocardial performance index and aortic isthmus size. CONCLUSIONS: It is feasible to quantitatively evaluate the left ventricular vortex in fetuses by BST. The fetuses with CoA exhibited greater vortex area and width, and the altered vortex property is associated with geometry of LV. This will facilitate our comprehension of the unique flow patterns and early cardiac remodeling in fetuses with CoA.

Coarctation duration and severity predict risk of hypertension precursors in a preclinical model and hypertensive status among patients.

Background: Coarctation of the aorta (CoA) often leads to hypertension (HTN) post-treatment. Evidence is lacking for the current >20 mmHg peak-to-peak blood pressure gradient (BPGpp) guideline, which can cause aortic thickening, stiffening and dysfunction. This study sought to find the BPGpp severity and duration that avoid persistent dysfunction in a preclinical model, and test if predictors translate to HTN status in CoA patients. Methods: Rabbits (N=75; 5-12/group) were exposed to mild, intermediate or severe CoA (≤12, 13-19, ≥20 mmHg BPGpp) for ~1, 3 or 22 weeks using dissolvable and permanent sutures with thickening, stiffening, contraction and endothelial function evaluated via multivariate regression. Relevance to CoA patients (N=239; age=0.01-46 years; median 3.7 months) was tested by retrospective review of predictors (preoperative BPGpp, surgical age, etc.) vs follow-up HTN status. Results: CoA duration and severity were predictive of aortic remodeling and active dysfunction in rabbits, and HTN in CoA patients. Interaction between patient age and BPGpp at surgery contributed significantly to HTN, similar to rabbits, suggesting preclinical findings translate to patients. Machine learning decision tree analysis uncovered that pre-operative BPGpp and surgical age predict risk of HTN along with residual post-operative BPGpp. Conclusions: These findings suggest the current BPGpp threshold determined decades ago is likely too high to prevent adverse coarctation-induced aortic remodeling. The results and decision tree analysis provide a foundation for revising CoA treatment guidelines considering the interaction between CoA severity and duration to limit the risk of HTN.

Case report: A novel combination of anomalies in a patient with 22q11.2 deletion syndrome.

A frequently occurring genetic disorder, 22q11.2 deletion syndrome can manifest with various abnormalities. The range of cardiac anomalies associated with this syndrome is extensive, with conotruncal defects being the most prevalent. In this study, we report the case of a patient with a unique combination of anatomical abnormalities such as crisscross pulmonary arteries, a cervical aortic arch with coarctation of the aorta, and a ventricular septal defect. The patient underwent initial surgical intervention, which resulted in significant clinical improvement.
