Surgical technical experience of adult aortic coarctation concomitant with poststenotic aneurysm or dissection.

Background: Aortic coarctation (COA) in adults combined with poststenotic aneurysm (PA) or poststenotic dissection (PD) is rare and challenging to manage. The existence of multiple factors such as kinking, comorbidities, previous surgical history, and descending aortic lesions increases the difficulty of treatment, and there are currently few clinical reports. The purpose of this study was to present our surgical experience in dealing with such patients. Methods: A retrospective study was conducted on 20 consecutive patients with COA combined with PA or PD who were treated in our center from December 2015 to April 2019. The basic principles, methods, and short- and mid-term prognosis of surgery are present carefully. This paper introduces the individualized treatment scheme as well as its advantages and disadvantages in detail. Results: The condition of the included patients was complicated, including 12 cases of PA and 8 of PD. Although different surgical schemes were adopted, procedural success rate was 100%. There were no other surgical complications except 2 cases of anastomotic bleeding and 1 case of spinal cord injury. The results of computed tomography angiography (CTA) demonstrated that 9 cases achieved anatomical correction, 10 cases of PA or PD were eliminated or thrombosed to varying degrees, and only 1 case of PA had no obvious change. Up to the follow-up period, except for 1 patient who had a slight cerebrovascular accident and 1 who had no change in PA underwent cheatham platinum (CP) stent surgery, no other cardiovascular adverse events occurred and all patients recovered well. Conclusions: The optimal surgical strategy developed collaboratively by cardiac surgeons and endovascular specialists has achieved satisfactory short- and mid-term results for COA patients combined with PA or PD. Further research is still necessary, due to the limited number of cases.

Partial atrioventricular canal defect and aortic coarctation associated with variants in GDF1 and NOTCH1 genes: A case report.

BACKGROUND: A peculiar subgroup of patients with partial or complete atrioventricular canal defect exhibits a spectrum of left-sided obstructions including right ventricular dominance and aortic coarctation. The association of atrioventricular canal defect with left-sided obstructions is found in several genetic syndromes; however, the molecular basis of nonsyndromic atrioventricular canal defect with aortic coarctation is still poorly understood. Although some candidate genes for nonsyndromic atrioventricular canal defect are known, a complex oligogenic inheritance determined in some cases by the co-occurrence of multiple variants has also been hypothesized. CASE REPORT: We describe a nonsyndromic infant with mesocardia with viscero-atrial situs solitus, partial atrioventricular canal defect, mild right ventricular dominance, and coarctation of the aorta. Next generation sequencing genetic testing revealed variants in two genes, GDF1 and NOTCH1, previously reported in association with atrioventricular canal defect and left-sided obstructive lesions, respectively. CONCLUSION: The present report could support the hypothesis that the co-occurrence of cumulative variants may be considered as genetic predisposing risk factor for specific congenital heart defects.

Stenting of aortic coarctation before coronary artery bypass surgery in an adult with acute myocardial infarction: a case report.

Background: Aortic coarctation is a major risk factor for high blood pressure and atherosclerotic disease development. Evidence is lacking regarding the treatment of acute coronary syndrome in patients with untreated aortic coarctation. Case summary: A 50-year-old male with a history of hypertension, diabetes, and haemodynamically significant untreated aortic coarctation presented to the emergency department with non-ST-elevation acute myocardial infarction. Coronary catheterization showed severe three-vessel disease. The aortic coarctation was addressed percutaneously using a covered CP stent. A quadruple coronary artery bypass surgery was conducted the following day. He was discharged home 10 days after surgery. Discussion: We describe a successful sequential approach involving the percutaneous repair of a native aortic coarctation followed by a surgical myocardial revascularization in the context of acute coronary syndrome. Discussion within a multidisciplinary Heart Team is key in patients with such complexity.

The Management of Aortic Coarctation Associated with Hypoplastic Arches and Particular Arch Anatomies: A Literature Review.

The surgical management of aortic coarctation in newborns needs to ensure postoperative evolution and long-term results as much as possible. Patients with a Gothic arch have a higher rate of postoperative hypertension, while newborns with a bovine arch have higher rates of restenosis and, thus, an additional risk of mortality. Late hypertension, even in anatomically successfully repaired patients, confers a high risk for cardiovascular events. This review of the literature focuses on the management of aortic coarctations associated with hypoplastic arch and particular arch anatomies, focusing on surgical techniques and their outcomes.

Echocardiography of persistent fifth aortic arch confirmed by computed tomography angiography or surgery in children: a case series.

BACKGROUND: The purpose of this study was to review echocardiography-based diagnosis of persistent fifth aortic arch (PFAA) in children. METHODS: From January 2015 to December 2022, we retrospectively analyzed the echocardiographic findings and the relevant clinical data during follow-up of patients with PFAA who were treated in the Third Affiliated Hospital of Zhengzhou University. The diagnosis was confirmed by computed tomography angiography or surgery. RESULTS: Seven PFAA cases included two Weinberg type A and five Weinberg type B. The anatomical details of PFAA were assessed using a combination of the long-axis view of the left ventricular outflow tract (from the left high parasternal window) and the long-axis view of the aortic arch (from the suprasternal window). In Weinberg type A, the distal fifth and fourth aortic arches were connected to the descending aorta, which was associated with aortic coarctation. In Weinberg type B, the upper arch of the fourth aorta was interrupted, and only the lower arch of the fifth aorta was connected to the descending aorta. Surgical repair of PFAA was indicated in five patients with blood flow disruption, among which four had good postoperative results and one refused surgery. Two patients with unobstructed PFAA blood flow required follow-up rather than surgery. CONCLUSIONS: It is feasible to diagnose PFAA by echocardiography. Combined application of the high parasternal left ventricular outflow tract view and the suprasternal aortic arch view can improve timely detection of different types of PFAA in children.

Human Genetics of Semilunar Valve and Aortic Arch Anomalies.

Lesions of the semilunar valve and the aortic arch can occur either in isolation or as part of well-described clinical syndromes. The polygenic cause of calcific aortic valve disease will be discussed including the key role of NOTCH1 mutations. In addition, the complex trait of bicuspid aortic valve disease will be outlined, both in sporadic/familial cases and in the context of associated syndromes, such as Alagille, Williams, and Kabuki syndromes. Aortic arch abnormalities particularly coarctation of the aorta and interrupted aortic arch, including their association with syndromes such as Turner and 22q11 deletion, respectively, are also discussed. Finally, the genetic basis of congenital pulmonary valve stenosis is summarized, with particular note to Ras-/mitogen-activated protein kinase (Ras/MAPK) pathway syndromes and other less common associations, such as Holt-Oram syndrome.

Exercise-induced hypertension after aortic coarctation repair: Our experience and a systematic review.

BACKGROUND: The exact prevalence and clinical significance of excessive increase in blood pressure in response to exercise in patients with repaired coarctation of aorta (CoA) remains unknown. AIM: This study aimed to investigate the impact of different definitions of exercise-induced hypertension (EIH) on the prevalence rates in our adult patients with repaired CoA. A systematic review of the available literature was also performed. METHODS: We retrospectively analyzed exercise test data from adult patients with repaired CoA followed at the national referral center for adult congenital heart disease between 1998 and 2021. The three most reported definitions of EIH in patients with repaired CoA were used for the analysis of EIH prevalence. We also performed a systematic search of the PubMed electronic bibliographic database. Full-text versions of all potentially relevant articles on EIH in CoA were reviewed for relevance. RESULTS: Our registry included 161 adult CoA patients. Complete exercise test results were available in 74 patients (59% male, median age 39 years [range 20-68 years]). The prevalence of EIH in our cohort varied from 24 to 41%, depending on the definition used. We identified eleven eligible articles from 184 publications. The reported prevalence rate of EIH in the studies ranged from 13% to 82%. CONCLUSION: EIH is common in patients with repaired CoA; however, the rates of EIH vary greatly depending on the definition used. A standardized and uniform EIH definition is needed to accurately assess the prevalence and clinical relevance of EIH in this population.

Aortic geometry and long-term outcome in patients with a repaired coarctation.

OBJECTIVE: This study aims to compare aortic morphology between repaired coarctation patients and controls, and to identify aortic morphological risk factors for hypertension and cardiovascular events (CVEs) in coarctation patients. METHODS: Repaired coarctation patients with computed tomography angiography (CTA) or magnetic resonance angiography (MRA) were included, followed-up and compared with sex-matched and age-matched controls. Three-dimensional aortic shape was reconstructed using patients' CTA or MRA, or four-dimensional flow cardiovascular magnetic resonance in controls, and advanced geometrical characteristics were calculated and visualised using statistical shape modelling. In patients, we examined the association of geometrical characteristics with (1) baseline hypertension, using multivariable logistic regression; and (2) cardiovascular events (CVE, composite of aortic complications, coronary artery disease, ventricular arrhythmias, heart failure hospitalisation, stroke, transient ischaemic attacks and cardiovascular death), using multivariable Cox regression. The least absolute shrinkage and selection operator (LASSO) method selected the most informative multivariable model. RESULTS: Sixty-five repaired coarctation patients (23 years (IQR 19-38)) were included, of which 44 (68%) patients were hypertensive at baseline. After a median follow-up of 8.7 years (IQR 4.8-15.4), 27 CVEs occurred in 20 patients. Aortic arch dimensions were smaller in patients compared with controls (diameter p<0.001, wall surface area p=0.026, volume p=0.007). Patients had more aortic arch torsion (p<0.001) and a higher curvature (p<0.001). No geometrical characteristics were associated with hypertension. LASSO selected left ventricular mass, male sex, tortuosity and age for the multivariable model. Left ventricular mass (p=0.014) was independently associated with CVE, and aortic tortuosity showed a trend towards significance (p=0.070). CONCLUSION: Repaired coarctation patients have a smaller aortic arch and a more tortuous course of the aorta compared with controls. Besides left ventricular mass index, geometrical features might be of importance in long-term risk assessment in coarctation patients.

Secondary hypertension and aortic coarctation in a young adult: A case report.

Aortic coarctation is a rare cause of secondary hypertension (<1% cases) and can be challenging to detect due to its few clinical manifestations. Early diagnosis and treatment are important because patients with unmanaged aortic coarctation are at increased risk of cardiovascular complications and have a reduced life expectancy. We describe a case of secondary hypertension in a young adult female caused by aortic coarctation, first detected in a general practitioner setting, resulting in the need for a left subclavian-carotid bypass vascular surgery and a descending aortic stent vascular surgery. This case highlights the critical role that proximity medicine in general practice can have in improving the early detection of clinically silent conditions by routinely monitoring blood pressure and other vital parameters, and the increasing importance of medical imaging in assisting early diagnosis and guiding the surgical management of complex cases.

Critical left main coronary artery stenosis presenting as cardiac arrest in coarctation of the aorta patient.

Congenital coronary artery stenosis coexisting with aortic coarctation in nonsyndromic patients has not previously been reported. This report describes a nonsyndromic aortic coarctation patient who experienced intraoperative cardiac arrest due to a previously undiagnosed critical left main coronary artery stenosis. The patient was successfully resuscitated, underwent patch coronary ostioplasty, and was discharged home. He remains well for four months following repair.

Evaluation of short and mid-term clinical outcomes in patients with aortic coarctation treated with self-expandable stents.

The present study aimed to evaluate the outcomes of percutaneous treatment of aortic coarctation using self-expandable uncovered Nitinol stents. We conducted a retrospective clinical data review of all patients with aortic coarctation and treated with self-expandable uncovered Nitinol stents at our institution between 2009 and 2019. The gradient pressure across the coarctation site was measured using aortography. Follow-up echocardiography and computed tomography angiography were performed to assess possible stent complications. A total of 127 stents were successfully implanted in 125 patients (64.8% males) with a mean age of 35.36 ± 11.9 years. The gradient across the coarctation site decreased significantly from 67.48 ± 14.79 to 5.04 ± 3.01 mmHg (P < 0.001) after self-expandable stent implantation. Systolic blood pressure (SBP) decreased significantly from 175.53 ± 15.99 to 147.22 ± 12.83 mmHg (P < 0.001) after self-expandable stenting. There were no major technical or clinical complications, including balloon rupture, aneurysmal formation, infection, secondary stent migration, thrombosis, death during the procedure, and in-hospital mortality. On a mean follow-up of 48 ± 23.6 months (12-120 months), the gradient [from 59.43 ± 15.42 to 3.72 ± 1.38 mmHg (P < 0.001)] and SBP [from 175.53 ± 15.99 to 127.99 ± 7.82 mmHg (P < 0.001)] decreased significantly. There was no mortality, aneurysmal formation in the stent site, dislocation, or aortic re-stenosis requiring intervention during mid-term follow-up. Treatment of aortic coarctation using a self-expandable uncovered nitinol stent is safe and effective with promising mid-term outcomes.

Repaired coarctation of the aorta does not affect four-dimensional flow metrics in bicuspid aortic valve disease.

OBJECTIVES: The objective of this study was primarily to compare four-dimensional flow magnetic resonance imaging metrics in the ascending aorta (AA) of patients with right-left fusion type bicuspid aortic valve (RL-BAV) and repaired coarctation of the aorta (CoA) to RL-BAV without CoA. Metrics of patients with RL-BAV were also compared to the matched group of patients with common tricuspid aortic valve (TAV). METHODS: Eleven patients with RL-BAV and CoA, 11 patients with RL-BAV without CoA and 22 controls with TAV were investigated. Peak velocity (cm/s), peak flow (ml/s) and flow displacement (%) were analysed at 5 pre-defined AA levels. In addition, regional wall shear stress (WSS, mN/m2), circumferential WSS (WSSc) and axial WSS (WSSa) at all levels were quantified in 6 sectors of the aortic circle. Averaged WSS values on each level (WSSavg, WSSc, avg and WSSa, avg) were calculated as well. RESULTS: Peak velocity at the proximal tubular AA was significantly lower in BAV and CoA group (P = 0.047) compared to BAV without CoA. In addition, the WSSa, avg was found to be higher for the BAV and CoA group at proximal AA respectively (P = 0.040). No other significant differences were found between these groups. BAV group's peak velocity was higher at every level (P < 0.001-0.004) compared to TAV group. Flow displacement was significantly higher for the BAV group at every level (P < 0.001) besides at the most distal level. All averaged WSS values were significantly higher in BAV patients in distal AA (P < 0.001-0.018). CONCLUSIONS: Repaired CoA does not relevantly alter four-dimensional flow metrics in the AA of patients with RL-BAV. However, RL-BAV majorly alters flow dynamics in the AA when compared to patients with TAV.

Case report of a rare cause of secondary hypertension illustrating the importance of cardio-obstetric preconception counselling.

Background: Cardiovascular diseases represent a leading cause of maternal morbidity and mortality in industrialized countries. High blood pressure during pregnancy is a major driver of short- and long-term cardiovascular health in both mother and child. Screening and adequate treatment of elevated blood pressure before pregnancy significantly reduce mortality risk to mother and child. Case summary: A 30-year-old woman with middle aortic coarctation (MAC) previously treated with aortic stenting was referred to our cardio-obstetrics with plans to become pregnant. The clinical examination revealed severe hypertension with a significant blood pressure gradient between the upper and lower limbs. The patient underwent computed tomography angiography showing re-stenosis of the aorta. After the analysis of the benefit risk of all treatment options, percutaneous transluminal aortic in-stent re-stenting was performed. Following the intervention, blood pressure profile significantly improved but remained slightly elevated further necessitating the introduction of an antihypertensive therapy. Discussion: This clinical case condenses several challenges encountered in the management of hypertension in women who plan to become pregnant. Firstly, it emphasizes the fact that secondary causes of chronic hypertension, including MAC, do not have to be overlooked in childbearing age patient. Secondly, it illustrates the need for a multidisciplinary analysis of all available treatment options in view of a future pregnancy. Finally, it discusses the particular follow-up and potential complications in pregnant women with MAC and aortic stent.

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.

Single-Lung Ventilation in Infants for Surgical Repair of Coarctation of The Aorta Without Cardiopulmonary Bypass.

OBJECTIVE: To investigate the effect of improving the operative field and postoperative atelectasis of single-lung ventilation (SLV) in the surgical repair of coarctation of the aorta (CoA) in infants without the use of cardiopulmonary bypass (CPB). METHODS: This was a retrospective cohort study. The clinical data of 28 infants (aged 1 to 4 months, weighing between 4.2 and 6 kg) who underwent surgical repair of CoA without CPB from January 2019 to May 2022 were analyzed. Fourteen infants received SLV with a bronchial blocker (Group S), and the other 14 infants received routine endotracheal intubation and bilateral lung ventilation (Group R). RESULTS: In comparison to Group R, Group S exhibited improved exposure of the operative field, a lower postoperative atelectasis score (P<0.001), reduced prevalence of hypoxemia (P=0.01), and shorter durations of operation, mechanical ventilation, and ICU stay (P=0.01, P<0.001, P=0.03). There was no difference in preoperative information or perioperative respiratory and circulatory indicators before SLV, 10 minutes after SLV, and 10 minutes after the end of SLV between the two groups (P>0.05). Intraoperative bleeding, intraoperative positive end-expiratory pressure (PEEP), and systolic pressure gradient across the coarctation after operation were also not different between the two groups (P>0.05). CONCLUSION: This study demonstrates that employing SLV with a bronchial blocker is consistent with enhanced operative field, reduced operation duration, lower prevalence of intraoperative hypoxemia, and fewer postoperative complications during the surgical repair of CoA in infants without the use of CPB.

Application of Computed Tomography Angiography in Preoperative Diagnosis of Coarctation of Aorta and Evaluation of Aortic Dilatation in Infants.

OBJECTIVE: To evaluate the occurrence of aortic dilatation and its associated predictors with coarctation of the aorta (CoA) in infants using multi-slice computed tomography (MSCT). METHODS: The clinical data of 47 infantile patients with CoA diagnosed by MSCT and 28 infantile patients with simple ventricular septal defect were analyzed retrospectively. Aortic diameters were measured at six different levels, and aortic sizes were compared by z score. The coarctation site-diaphragm ratio was used to describe the degree of narrowing. Relevant clinical data were collated and analyzed. RESULTS: The dilation rate and z score of the ascending aorta in the severe CoA group were significantly higher than those in the mild CoA group (11 [52.38%] vs. 21 [80.77%], P=0.038 and 2.00 ± 0.48 vs. 2.36 ± 0.43, P=0.010). Pearson's correlation analysis found that the z score of the ascending aorta was negatively correlated with the coarctation site-diaphragm ratio value (r=-0.410, P=0.004). A logistic retrospective analysis found that an increased degree of coarctation was an independent predictor of aortic dilatation (adjusted odds ratio 0.002; 95% confidence interval 0.00-0.819; P=0.043). The z score of the ascending aorta in the severe CoA group was significantly higher than that in the ventricular septal defect group (P<0.05). CONCLUSION: Most infants with CoA can also have significant dilatation of the ascending aorta, and the degree of this dilatation is related to the degree of coarctation. Assessment of aortic diameter and related malformations by MSCT can predict the risk of aortic dilatation in infants with CoA.

Surgically induced aortic coarctation in a neonatal porcine model allows for longitudinal assessment of cardiovascular changes.

Noncritical aortic coarctation (COA) typically presents beyond early childhood with hypertension. Correction of COA does not ensure a return to normal cardiovascular health, but the mechanisms are poorly understood. Therefore, we developed a porcine COA model to study the secondary cardiovascular changes. Eight male neonatal piglets (4 sham, 4 COA) underwent left posterolateral thoracotomy with descending aorta (DAO) mobilization. COA was created via a 1-cm longitudinal DAO incision with suture closure, plication, and placement and an 8-mm external band. All animals had cardiac catheterization at 6 (11-13 kg), 12 (26-31 kg), and 20 (67-70 kg) wk of age. Aortic luminal diameters were similar along the thoracic aorta, except for the COA region [6.4 mm COA vs. 17.3 mm sham at 20 wk (P < 0.001)]. Collateral flow could be seen as early as 6 wk. COA peak systolic pressure gradient was 20 mmHg at 6 wk and persisted through 20 wk increasing to 40 mmHg with dobutamine. Pulse pressures distal to the COA were diminished at 12 and 20 wk. This model addresses many limitations of prior COA models including neonatal creation at an expected anatomic position with intimal injury and vessel sizes similar to humans.NEW & NOTEWORTHY A neonatal model of aortic coarctation was developed in a porcine model using a readily reproducible method of aortic plication and external wrap placement. This model addresses the limitations of existing models including neonatal stenosis creation, appropriate anatomic location of the stenosis, and intimal injury creation and mimics human somatic growth. Pigs met American Heart Association (AHA) criteria for consideration of intervention, and the stenoses were graded as moderate to severe.

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 posttreatment. Evidence is lacking for the current >20 mm Hg peak-to-peak blood pressure (BP) 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 hypertension status in patients with CoA. METHODS: Rabbits (n=75; 5-12/group) were exposed to mild, intermediate, or severe CoA (≤12, 13-19, ≥20 mm Hg 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 patients with CoA (n=239; age, 0.01-46 years; median 3.7 months) was tested by retrospective review of predictors (preoperative BPGpp, surgical age, etc.) versus follow-up hypertension status. RESULTS: CoA duration and severity were predictive of aortic remodeling and active dysfunction in rabbits, and hypertension in patients with CoA. Interaction between patient age and BPGpp at surgery contributed significantly to hypertension, similar to rabbits, suggesting preclinical findings translate to patients. Machine learning decision tree analysis uncovered that preoperative BPGpp and surgical age predict risk of hypertension along with residual postoperative 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 hypertension.

Life-Threatening Hemoptysis From Aorto-Bronchial Fistula in a Patient With Remote History of Aortic Coarctation Repair.

"Hemoptysis" refers to the expectoration of blood from the respiratory tract. However, "life-threatening hemoptysis" includes any volume that leads to features such as airway obstruction, hypoxia, or hemodynamic instability. We present a case of life-threatening hemoptysis in a 65-year-old male with a history of benign prostatic hyperplasia and uncontrolled hypertension. Radiological investigations revealed a pseudo-aneurysm at the site of a prior thoracic aortic coarctation repair more than 50 years prior in childhood. He required vascular surgical intervention, during which there was evidence of an aorta-bronchial fistula as the likely cause of bleeding. Following the repair and optimal blood pressure control, the patient had no further episodes of hemoptysis and was discharged from the hospital. His case not only adds to the growing body of medical literature reporting hemoptysis as a complication of coarctation repair but also highlights the aorto-bronchial fistula as a possible and potentially catastrophic mechanism for bleeding in these patients.
