The article by Naimo and colleagues (outcomes of truncus arteriosus repair in children: 35 years of experience from a single center) provides the initial glimpse at long-term outcomes following truncus arteriosus repair. Although survival has improved over the past decade, the morbidity resulting from subsequent re-operations now comprises a significant area for improvement in the ensuing decade.

We evaluated the long-term outcomes following repair of truncus arteriosus (TA) from a single institution. We conducted a retrospective review of children (n = 171) who underwent TA repair between 1979 and 2014. Early mortality rate was 11.7% (20/171). There were 19 late deaths. Most deaths (74%, 29/39) occurred within the first year following surgery. The 1-year mortality rate in 1979-2004 was 18% (25/136) and decreased to 11% (4/35) in 2005-2014. The overall survival rate was 73.6% at 30 years. Multivariate analysis identified postoperative extracorporeal membrane oxygenation (P = 0...

Perventricular Melody valve placement has been described as a bailout approach or alternative RVOT approach in patients >30 kg. We present three patients <20 kg and two patients with limited venous access, where we electively performed the perventricular approach. Retrospective analysis of patients <30 kg and vascular access limitation undergoing elective hybrid pulmonary valve replacement were reviewed. The subcostal approach was performed without sternotomy with the sheath introduced through the diaphragmatic surface of the right ventricle...

Both CHARGE syndrome and DiGeorge anomaly are frequently accompanied by cardiovascular malformations. Some specific cardiovascular malformations such as interrupted aortic arch type B and truncus arteriosus are frequently associated with 22q11.2 deletion syndrome, while conotruncal defects and atrioventricular septal defects are overrepresented in patients with CHARGE syndrome. CHD7 gene mutation is identified in approximately two-thirds of patients with CHARGE syndrome, and chromosomal microdeletion at 22q11...

Background: Delayed or missed diagnosis of critical and cyanotic congenital heart disease (CHD) in asymptomatic newborns may result in significant morbidity and mortality. The aim of this study was to determine the accuracy of pulse oximetry screening performed on the first day of life for the early detection of critical and cyanotic CHD in apparently normal newborns. Methods: This cross-sectional study used postductal pulse oximetry to evaluate term neonates born between 2008 and 2011 with normal physical examinations...

Since the year 2000, we have used Contegra conduits for right ventricular outflow tract reconstruction in infants and newborns. Published reports of early and late results from multiple centers have included variable and inconsistent findings. Concerns about the durability of small conduits placed in younger infants have been expressed. We report an interesting experience with a 12-mm Contegra conduit that we explanted 16 years after implantation in the course of repair of truncus arteriosus (common arterial trunk) in an infant...

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital anomaly characterized by complete or partial aplasia of the uterus and the upper part of the vagina. It is reported to be associated with cardiovascular disorders including atrial septal defect, anomalous pulmonary venous return, aortopulmonary window, pulmonary valve stenosis, mitral valve prolapse, tetralogy of Fallot, truncus arteriosus, and patent ductus arteriosus. Herein, for the first time in the medical literature, we present percutaneous closure of an isolated ostium secundum atrial septal defect in this syndrome...

OBJECTIVE: To determine the birth prevalence of congenital heart defects (CHDs) across the spectrum of common defects in very/extremely premature infants and to compare mortality rates between premature infants with and without CHDs. STUDY DESIGN: The Kids' Inpatient Databases (2003-2012) were used to estimate the birth prevalence of CHDs (excluding patent ductus arteriosus) in very/extremely premature infants born between 25 and 32 weeks' gestational age. Birth prevalence was compared with term infants for a subset of "severe" defects expected to be near universally diagnosed in the neonatal period...

Pseudoaneurysm formation is a rare but potentially life-threatening complication after surgical repair of congenital heart disease. We present a boy with truncus arteriosus communis 14 years after homograft placement in pulmonary position. On follow-up, he presented progressive chronic homograft degeneration. Moreover, a large pseudoaneurysm in the right ventricular outflow tract was surprisingly depicted. We opted for a two-stage interventional approach.

The situs, or pattern of anatomic organization, of the subarterial infundibulum and of the great arteries and the degree of development of the subarterial infundibulum largely determine whether the great arteries are normally or abnormally related. There are 2 types of situs: solitus (normal) and inversus (a mirror image of solitus). Situs ambiguus means that the pattern of anatomic organization is uncertain or unknown. Infundibular development varies from absent, to atretic, to severely stenotic, to mildly or moderately stenotic; great arteries are solitus normally related or inversus normally related, respectively...

An intramural coronary artery in the setting of truncus arteriosus (common arterial trunk) is an uncommon association. Following an uneventful surgical repair, a neonate developed a low cardiac output state deteriorating into cardiac arrest shortly after arrival into the intensive care unit, requiring extracorporeal membrane oxygenation support. Echocardiography and angiography showed occlusion of the left coronary artery, prompting emergency surgical reexploration. A "slit-like" orifice with an intramural left coronary artery was successfully unroofed, allowing full recovery...

The unilateral absence of a proximal pulmonary artery (UAPPA) is rare and is most frequently accompanied by cardiovascular anomalies such as tetralogy of Fallot or septal defects. We report a patient with truncus arteriosus with UAPPA in which we performed a two-stage surgical repair. During the first palliative operation, a right modified Blalock-Taussig shunt was constructed to develop the hypoplastic right pulmonary artery. At 10 months, the patient underwent patch closure of a ventricular septal defect with integration of both pulmonary arteries, and reconstruction of the right ventricular outflow tract using a conduit...

Cardiac neural crest cell (CNCC) ablation creates congenital heart defects (CHDs) that resemble those observed in many syndromes with craniofacial and cardiac consequences. The loss of CNCCs causes a variety of great vessel defects, including persistent truncus arteriosus and double-outlet right ventricle. However, because of the lack of quantitative volumetric measurements, less severe defects, such as great vessel size changes and valve defects, have not been assessed. Also poorly understood is the role of abnormal cardiac function in the progression of CNCC-related CHDs...

REVIEW
W Aaron Kay
Thoracic aortic dilation (AD) has commonly been described in conotruncal defects (CTDs), such as tetralogy of Fallot, double outlet right ventricle and transposition of the great arteries, and truncus arteriosus. Several theories for this have been devised, but fairly recent data indicate that there is likely an underlying histologic abnormality, similar to that seen in Marfan and other connective tissue disease. The majority of aortic dissection in the general population occurs after the age of 45 years, and there have been very few case reports of aortic dissection in CTD...

BACKGROUND: Among patients with congenital heart disease (CHD), the coexistence of noncardiac congenital anatomic abnormalities (NC), genetic abnormalities (GA), and syndromes (S) may influence therapeutic strategies and outcomes. The appreciated prevalence of these abnormalities has risen because increased screening and improved diagnostic precision enable identification of these comorbidities in a larger fraction of neonates with CHD. We examined the contemporary prevalence and distribution of NC/GA/S across diagnostic groups among neonates undergoing cardiac operations using a large nationally representative clinical registry...

Persistent truncus arteriosus is a rare congenital cardiac disease with variable presentation. The exact preoperative diagnosis and delineation of anatomy are very important because the optimal timing and procedure for truncus arteriosus repair are decided on the basis of the morphological characteristics. Moreover, the presence of associated anomalies influences the surgical outcome and mortality in these patients. Dual-source computed tomographic evaluation with three-dimensional post-processing is highly valuable for delineating its precise morphology and to identify and characterize the associated anomalies...
