OBJECTIVE: Three-dimensional (3D) printing is a manufacturing method by which an object is created in an additive process, and can be used with medical imaging data to generate accurate physical reproductions of organs and tissues for a variety of applications. We hypothesized that using 3D printed models of congenital cardiovascular lesions to supplement an educational lecture would improve learners' scores on a board-style examination. DESIGN AND INTERVENTION: Patients with normal and abnormal aortic arches were selected and anonymized to generate 3D printed models...

We report the case of a 25-year-old woman with a pulmonary artery sling who was misdiagnosed as having childhood-onset refractory asthma for approximately 20 years. The use of computed tomography may be useful for diagnosing this rare condition.

We present a case of a 10-month-old girl baby with pulmonary artery sling and bridging bronchus demonstrated using multidetector computed tomography with a three-dimensional volume-rendering display and minimum intensity projections. To the best of our knowledge, this method has been helpful not only in the diagnosis and surgical planning for this rare abnormality but also in the evaluation of prognosis. After pulmonary artery reimplantation, the patient was well and discharged.

OBJECTIVE: The aim of this study was to present relationship between partial anomalous left pulmonary artery (PALPA) and the tracheobronchial tree and patterns of the tracheobronchial tree assessed by multislice computed tomography (MSCT). METHODS: Nine patients were assessed by MSCT. The relationships between the tracheobronchial tree and PALPA and different tracheobronchial patterns, location of tracheobronchial stenosis, severity of stenosis, and associated cardiac defects were evaluated...

Pulmonary artery sling (PAS) is a rare congenital condition in which the left pulmonary artery (LPA) arises from the right pulmonary artery, and then passes between the trachea and the esophagus to reach the left lung, thereby forming a sling around the airway. It is often associated with intrinsic tracheal stenosis due to complete cartilaginous rings. Therapeutic management nowadays consists of one-stage reimplantation of the LPA and tracheoplasty with cardiopulmonary bypass support. Here, we present a 7-week-old boy with PAS and long-segment tracheal stenosis (LSTS) who underwent surgical intervention consisting of reimplantation of the LPA and slide tracheoplasty...

We evaluated the prevalence, image appearance, associated cardiovascular anomalies, and surgical outcomes of left pulmonary artery sling (LPAS) using cardiovascular computed tomography angiography (CCTA). A retrospective search of patients from our database between October 2007 and December 2014 identified 52,200 patients with congenital heart diseases (CHD) referred for CCTA, echocardiography, or magnetic resonance imaging. Clinical information, CCTA findings, associated cardiovascular anomalies, and surgical outcomes were analyzed...

OBJECTIVE: Congenital anomalies of the pulmonary arteries are uncommon. They can occur in isolation or in association with congenital heart defects. Isolated congenital anomalies remain undiscovered until they are reported as incidental findings on imaging tests, usually not until adolescence. We review the embryological development and normal anatomy of the pulmonary arteries as well as the spectrum of computed tomography findings for various congenital anomalies: unilateral interruption of the pulmonary artery, anomalous origin of the left pulmonary artery (pulmonary artery sling), idiopathic aneurysm of the pulmonary artery, and other anomalies associated with congenital heart defects...

Left pulmonary artery slings and vascular rings are rare congenital anomalies definable by fetal echocardiography. Left pulmonary artery slings are associated with high respiratory morbidity and mortality. Prenatal diagnosis of a left pulmonary artery sling should prompt delivery planning for postnatal management at a pediatric tertiary care center.

BACKGROUND: Vascular rings (VRs) are recognized as uncommon but not rare cardiovascular malformations. METHODS: We analyzed data from all patients born in Southern Nevada, who underwent diagnosis and management of VR from 1990 to 2015, RESULTS: From 1990 to 2015, a total of 92 patients were diagnosed prenatally and postnatally. Of the 92 patients, 73 (79%) had right aortic arch and aberrant left subclavian artery (RAA-ALS) with a left ductus arteriosus or ligamentum, 17 (19%) had a double aortic arch (DAA), and 2 (2%) had a pulmonary artery sling...

The involvement of the airway is not uncommon in the presence of complex cardiovascular malformations. In these cases, a careful inspection of the relationship between the airway and the vasculature is paramount to plan the surgical procedure. Three-dimensional printing enhanced the visualization of the cardiovascular structure. Unfortunately, IT does not allow to remove selected anatomy to improve the visualization of the surrounding ones. Computerized modeling has the potential to fill this gap by allowing a dynamic handling of different anatomies, increasing the exposure of vessels or bronchi to show their relationship...

We present two interesting cases of isolated left subclavian artery from the pulmonary artery with symptoms of upper airway obstruction. The first patient had tetralogy of Fallot, pulmonary artery sling, bilateral superior caval veins, and left bronchial isomerism, suggesting heterotaxy syndrome. The second patient had a right aortic arch, isolated left subclavian artery, and bilateral arterial ducts. These two cases are interesting because of their rarity and uncommon presentation.

OBJECTIVES: Surgery for vascular anomalies can occasionally fail to relieve symptoms, especially when severe tracheobronchial malacia persists. We studied outcomes in children who underwent airway stenting for severe post-surgical airway malacia and tested known clinical and surgical prognostic factors. METHODS: Among 257 children evaluated for tracheobronchial vascular compression, we reviewed the clinical charts for the 59 patients (23%) who underwent surgery...

A neonate with severe neonatal asphyxia was treated with therapeutic hypothermia. He developed hypothermia-induced respiratory deterioration, after which congenital tracheal stenosis and pulmonary artery sling were diagnosed. Even low-grade hypothermia is likely to induce bronchial narrowing in neonates, especially in neonates with congenital respiratory tract anomalies. Congenital tracheal stenosis represents a potential pitfall in differential diagnosis and should be carefully ruled out in cases of bronchial narrowing episode induced by therapeutic hypothermia...

BACKGROUND: Vascular rings may cause pressure on the trachea and/or esophagus of varying degree, resulting in symptoms. This study assessed the presentation symptoms, diagnostic methods and treatment results after surgery in children with vascular ring. METHODS: Symptomatic vascular ring patients undergoing surgery between January 2010 and August 2014 at Mehmet Akif Ersoy Cardiovascular Research and Training Hospital, Istanbul, were retrospectively assessed. The presentation symptoms, demographic characteristics, and diagnostic tests were evaluated...

The term vascular ring refers to congenital vascular anomalies of the aortic arch system that compress the esophagus and trachea, causing symptoms related to those two structures. The most common vascular rings are double aortic arch and right aortic arch with left ligamentum. Pulmonary artery sling is rare and these patients need to be carefully evaluated for frequently associated tracheal stenosis. Another cause of tracheal compression occurring only in infants is the innominate artery compression syndrome...

Isolated anomalies of the branch pulmonary arteries are rare, more often occurring in the setting of complex congenital heart disease. These isolated anomalies are often not identified in the prenatal period. We describe two cases of isolated anomalies of the left pulmonary artery which were identified on fetal echocardiography and confirmed postnatally, an anomalous left pulmonary artery arising from the base of the left-sided brachiocephalic artery in the setting of a right-sided aortic arch, and a left pulmonary artery sling...
