Surgical repair of double aortic arch: 16-year experience

Double aortic arch (DAA) is a complete form of vascular ring causing tracheoesophageal compression. We analyzed long-term results of a series of DAAs, over a period of 16 years. Between 1987 and 2003, 29 children underwent surgery for airway and/or esophageal compression secondary to a DAA. Dominant symptoms were stridor, dysphagia, choking episodes, and life-threatening apneic spells (n = 7). Diagnosis was established by barium studies, bronchoscopy, echocardiogram, angiogram, computed tomography (CT), and magnetic resonance imaging (MRI). Seven patients had concurrent cardiac anomalies. Two children had an associated tracheoesophageal fistula. Surgery was accomplished by left thoracotomy (n = 25), right thoracotomy (n = 2) or median sternotomy (n = 2). The operative mortality was zero. There was one late death due to respiratory failure. Four (13.8%) patients had a surgical complication (chylothorax, 3 cases; acute renal failure, 1 case). Follow-up (mean 7.1 years; range 6 months to 16 years) was complete in all patients, and showed complete improvement in 22 patients and partial improvement in 6 patients. Early surgical repair of DAA is associated with low mortality, and results in marked symptomatic relief in most patients. Patients with tracheomalacia or associated asthma, constitute a high-risk group and may manifest persistent symptoms and require adjunctive procedures.     

Right patent ductus arteriosus with an ipsilateral aortic arch: percutaneous closure with amplatzer devices

The association of a right aortic arch with an ipsilateral patent ductus arteriosus is rare, especially when there are no other intracardiac anomalies. We report three female patients aged 26, 35 and 9 years with this combination in whom previous attempts at surgical closure by thoracotomy and sternotomy were unsuccessful and who subsequently underwent successful percutaneous closure of the defects using Amplatzer devices. In two patients, although angiography demonstrated the presence of type-A patent ductus arteriosus, it was not possible to determine the minimum diameter accurately and it was necessary to measure it using a sizing balloon. An Amplatzer duct occluder was used in two patients and an Amplatzer muscular ventricular septal defect occluder, in the other. In all patients, full closure was confirmed in the catheterization laboratory and the patients were discharged on the same day with no complications. Percutaneous closure of a right patent ductus arteriosus associated with a right aortic arch is feasible, safe and effective.     

Diagnostic Role of Magnetic Resonance Imaging in Identifying Aortic Arch Anomalies

Purpose. The aim of this article was to assess the role of MRI in the diagnosis and management of a variety of complex aortic arch anomalies. Materials and Methods. Imaging was performed on a 1.5T Philips Gyroscan Intera. We retrospectively reviewed all cardiac MR scans performed from November 2003 to February 2007 at our institute to identify aortic arch anomalies. Magnetic resonance imaging included three‐dimensional (3D) sagittal volume images, cine images, short axis ventricular volumes, phase contrast flow of great vessels, and 3D gadolinium magnetic resonance angiogram. Results. Three major categories of anomalies were identified in 47 patients: double aortic arch (n = 9), right‐sided aortic arch with mirror image branching (n = 28), and aberrant right subclavian artery (n = 10). In the double aortic arch group, six patients were symptomatic, and four of them underwent a surgical division. Magnetic resonance imaging was used to plan the surgical management. In the other two groups, no patient presented with symptoms of airway or esophageal compression, and the arch abnormalities were noticed during investigation for other associated cardiac disease. However, we noticed a strong correlation with well‐defined subgroups of congenital heart disease. Right‐sided aortic arch was seen in patients with pulmonary atresia with ventricular septal defect (46.4%), tetralogy of Fallot (32.1%), and double outlet right ventricle with right atrial isomerism (14.2%). Seventy percent of the patients with aberrant right subclavian artery had aortic coarctation, and another case presented a complete aortic arch interruption. Conclusion. Magnetic resonance imaging is an important diagnostic tool in identifying anomalies of the aortic arch and its branches and can be considered the imaging technique of choice when planning surgical management, especially when there are associated cardiac anomalies.

Microcinephotography of the developing heart in neural crest-ablated chick embryos

Microcinephotography was used to study heart development in a neural crest model of heart defects, that is, persistent truncus arteriosus, interrupted aortic arch, double outlet right ventricle, or single ventricle and tricuspid valve anomalies. These defects were created in chick embryos by ablation of premigratory neural crest destined for the aorticopulmonary and truncal septa, as well as the third and fourth aortic arch arteries. When embryogenesis reached the looped cardiac tube stage of development (Hamburger-Hamilton stage 18), 19 experimental and 15 control embryos were filmed at 100 frames per second under controlled environmental conditions. Analysis of the microcinephotography films showed the following significant distinguishing characteristics of the developing heart in the experimental embryos: altered conotruncal shape in 100%, depressed contractility and dilation of the primitive ventricle in 84%, decreased emptying of the bulbus cordis in 79%, incompetent truncal cushions in 68%, incomplete looping of the cardiac tube in 58%, and fourth right aortic arch artery without blood flow and third right aortic arch artery with increased flow in 53%. These abnormal characteristics suggested that there were functional and morphological changes in the developing heart of experimental embryos before the time when the predicted structural heart defects would be apparent. It is proposed that the primitive ventricle might attempt to compensate for depressed contractility by ventricular dilation. The incompetent truncal cushions could be secondary to the depressed contractility or secondary to the neural crest ablation that is known to cause persistent truncus arteriosus, an interrupted aortic arch, or both. The absence of blood flow in the right fourth aortic arch artery that will become the definitive aorta correlates with the expected incidence of interrupted aortic arches in this neural crest-ablation model of heart defects. It is speculated that the incomplete looping of the cardiac tube might hinder normal developmental alignment of the outflow and inflow tracts, producing a spectrum of lesions of maldevelopment of the tricuspid valve and dextroposition of the aorta.     

Ductal Arteriosus Aneurysm,Right Aortic Arch,and Isolated Left Subclavian Artery in a Neonate

Ductal arteriosus aneurysm (DAA) is a well‐recognized condition, especially in infancy, and is usually asymptomatic. We report the first case of a newborn who presented with significant inspiratory stridor and, using multiple imaging investigations, was subsequently diagnosed with the rare constellation of a congenital DAA, a right aortic arch and an isolated left subclavian artery with normal intra‐cardiac anatomy. The patient underwent surgical resection of the DAA with significant improvement in symptoms.     

Truncus arteriosus and double aortic arch associated with DiGeorge syndrome

We report the 1st known case in which truncus arteriosus and double aortic arch have been associated with DiGeorge syndrome. The association of these 2 cardiovascular anomalies lends support, by itself, to speculation that truncus arteriosus and double aortic arch have a common embryonic pathogenesis; and the presence of these anomalies in a patient with DiGeorge syndrome strengthens the contention that the common causative factor is pathologic development of the neural crest cells.     

Interrupted aortic arch: brief review and summary of an eighteen-year experience

Interrupted aortic arch (IAA) is an uncommon congenital anomaly representing approximately 1% of congenital heart disease. More than 97% of the cases also have associated cardiac anomalies complicating their treatment. Because the median age at death in untreated cases is 10 days, this condition usually occurs as a complicated neonatal surgical emergency. There are three types of IAA: Type A is interrupted distal to the left subclavian artery. Type B, which is the most common form, is interrupted between the left common carotid and the left subclavian arteries. Type C, which is the most uncommon type, is interrupted between the innominate and left common carotid arteries. Since the first patient with this congenital anomaly was treated at our institution in 1965, 39 patients have undergone surgical treatment. Two of these (4.6%) had no associated intracardiac lesions, and both survived bypass grafting without complications. There were 12 Type A (30%), 26 Type B (67%) and one Type C (3%). A variety of individualized techniques were used to repair the defects. The three basic techniques were (1) direct aortic to aortic anastomosis bridging the gap, (2) "turndown" or "turnup" of one of the arch vessels to the aorta across the gap, or (3) bypass of the interruption with graft material. Because aortic arch and associated cardiac anomalies represent a neonatal surgical emergency, our therapeutic plan consists of treatment for biventricular failure and PGE(1) infusion to maintain ductal patency, and surgical correction as soon as feasible.
