Infrared multiple photon dissociation spectroscopy was performed on protonated and cationized canavanine (Cav), a non-protein amino acid oxy-analog of arginine. Infrared spectra in the XH stretching region (3000 - 4000 cm-1 ) were obtained at the Centre Laser Infrarouge d'Orsay (CLIO) facility. Comparison of the experimental infrared spectra with scaled harmonic frequencies at the B3LYP/6-31+G(d,p) level of theory indicates that canavanine is in a canonical neutral form in CavH+ , CavLi+ , and CavNa+ ; therefore, these cations are charge-solvated structures...

BACKGROUND: Major aortopulmonary collateral arteries (MAPCAs) are frequently found in association with pulmonary atresia with ventricular septal defect (PA/VSD). However, some patients with MAPCAs do not have PA/VSD but have a variety of other "atypical" anatomic diagnoses. METHODS: This was a retrospective review of patients with MAPCAs and atypical anatomy. The 50 patients with MAPCAs could be divided into two subgroups: (1) single ventricle anatomy (n = 33) and (2) two ventricle anatomy (n = 17)...

BACKGROUND: Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) is a challenging operation increasingly being performed as a complete, primary repair in infancy. Previous studies have focused on perioperative outcomes; however, midterm valve function, ventricular function, and residual obstruction have received little attention. METHODS: We retrospectively reviewed 20 patients who underwent CAVC/TOF repair (January 2005 to December 2014)...

Aortic insufficiency (AI) is a significant complication of long-term support of continuous flow left ventricular assist device (CF-LVAD) for patients with end-stage heart failure. A 26-year-old female with osteogenesis imperfecta (OI) was diagnosed with dilated phase hypertrophic cardiomyopathy (d-HCM)) and was implanted with Jarvik 2000, for bridge to transplantation. AI gradually developed and surgical intervention was indicated. We performed central aortic valve closure (CAVC) instead of valve replacement 20 months after CF-LVAD implantation...

BACKGROUND: Several past clinical studies have demonstrated that frequent and unnecessary right ventricular pacing in patients with sick sinus syndrome and compromised atrio-ventricular conduction (AVC) produces long-term adverse effects. The safety and efficacy of two pacemaker algorithms, Ventricular Intrinsic Preference™ (VIP) and Ventricular AutoCapture (VAC), were evaluated in a multi-center study in pacemaker patients. METHODS: We evaluated 80 patients across 10 centers in India...

OBJECTIVES: Aortic insufficiency (AI) after continuous-flow left ventricular assist device implantation can affect patient outcomes. Central aortic valve closure (CAVC) is a strategy commonly practiced; however, its efficacy has not been extensively investigated. METHODS: From March 2004 to May 2014, a total of 340 patients received a continuous-flow left ventricular assist device (89; 26.2%) as destination therapy (DT). Outcomes were compared between patients with CAVC (n = 57 [16...

Williams-Beuren Syndrome (WBS) is a well-described microdeletion syndrome characterized by specific dysmorphic facial features, peripheral pulmonic stenosis, supravalvular aortic stenosis, hypercalcemia, feeding difficulties, gastroesophageal reflux, short stature, and specific intellectual disabilities (such as visual spatial problems). WBS is caused by 7q11.23 deletions that contain multiple genes known to contribute to the above phenotype. We report a neonate with a complete atrioventricular canal (CAVC) defect, an atypical cardiac lesion for WBS, and few typical phenotypic features of WBS, diagnosed at 20 days of life...

OBJECTIVES: Parachute left atrioventricular (AV) valve can complicate repair of common atrioventricular canal (CAVC), and single-ventricle palliation is sometimes preferred. The goal of this study is to review our single institutional experience in biventricular repair in this patient group. METHODS: The demographic, procedural and outcome data were obtained for all children who underwent biventricular repair for complete CAVC with parachute [single left ventricular (LV) papillary muscle] or forme fruste parachute left AV valve (closely spaced LV papillary muscles) from 2001 to 2012...

In this study, we tested the hypothesis that cerebral hypoperfusion after asphyxia and induced hypothermia is associated with reduced circulating nitrite levels as an index of nitric oxide synthase (NOS) activity. The preterm fetal sheep at 0.7 gestation (103-104 days, term = 147 days) received 25-minute umbilical cord occlusion, followed by mild whole-body cooling from 30 minutes to 72 hours after occlusion. Occlusion and induced hypothermia were independently associated with reduced carotid vascular conductance (CaVC) from 2 to 72 hours, and with transiently suppressed plasma nitrite levels at 6 hours...

The multidrug resistance-encoding IncA/C conjugative plasmids disseminate antibiotic resistance genes among clinically relevant enteric bacteria. A plasmid-encoded disulfide isomerase is associated with conjugation. Sequence analysis of several IncA/C plasmids and IncA/C-related integrative and conjugative elements (ICE) from commensal and pathogenic bacteria identified a conserved DsbC/DsbG homolog (DsbP). The crystal structure of DsbP reveals an N-terminal domain, a linker region, and a C-terminal catalytic domain...

Atrioventricular canal and conotruncal anomalies are a heterogeneous group of lesions presenting unique challenges for surgical repair. These are the establishment of unobstructed pathways from left ventricle (LV) to aorta and from right ventricle (RV) to pulmonary artery, closure of the inlet ventricular septal defect (VSD) and atrial septal defect (ASD) ostium primum, and the avoidance of significant left and right atrioventricular valve (AV) regurgitation. Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) has been most commonly achieved, either using a single-patch or a 2-patch technique...

Disease causing mutations for heterotaxy syndrome were first identified in the X-linked laterality gene, ZIC3. Mutations typically result in males with situs ambiguus and complex congenital heart disease; however affected females and one male with isolated d-transposition of the great arteries (d-TGA) have been reported. We hypothesized that a subset of patients with heart defects common to heterotaxy but without laterality defects would have ZIC3 mutations. We also sought to estimate the prevalence of ZIC3 mutations in sporadic heterotaxy...

BACKGROUND: Complete atrioventricular canal defects (CAVC) are a common heart defect, but few epidemiologic studies have evaluated non-syndromic CAVC. Risk factors for non-syndromic CAVC have not been well established. METHODS: To assess the relationship between risk for non-syndromic CAVC in offspring and several sociodemographic and reproductive parental factors, including maternal diabetes and obesity, we conducted Poisson regression analyses, using data ascertained through the Texas Birth Defects Registry, a large, population-based birth defects registry...

Common atrioventricular canal (CAVC) is a common congenital heart lesion resulting from a defect in development of the endocardial cushions during early embryogenesis. Depending on the type of defect, CAVC can encompass a spectrum of lesions ranging from partial atrioventricular (AV) canal to complete AV canal. We describe a case of CAVC with unique anatomy in a 4-month-old male infant with Down syndrome.

BACKGROUND: In response to increasing demand for a more sophisticated newborn baby health examination, we designed and performed echocardiographic screenings on a voluntary and self-paid basis. METHODS: From 1997 to 2005, 10,000 newborn babies had received the echocardiographic examination on the next day after birth. The echocardiographic examinations were performed by a single sonographer. RESULTS: As well as physically patent ductus arteriosus (PDA) (2420 cases), and patent foramen ovale (PFO) (5813 cases), we also found atrial septal defect (ASD) (161 cases), muscular-type ventricular septal defect (VSD) (123 cases), perimembranous type VSD (58 cases), coarctation of the aorta (COA) (1 case), pulmonic stenosis (PS) (1 case), peripheral pulmonic stenosis (PPS) (15 cases), common atrioventricular canal (CAVC) (1 case), transposition of the great arteries (TGA) (3 cases), double outlets of the right ventricle (DORV) (2 cases), tetralogy of Fallot (TF) (2 cases), hypertrophic cardiomyopathy (2 cases), dextrocardia (2 cases) and cardiac tumor (2 cases)...

REVIEW
Carl Lewis Backer, Robert D Stewart, Constantine Mavroudis
Surgical management of pediatric patients with the diagnosis of complete atrioventricular canal (CAVC) is accomplished by using one of three procedures: (1) the classic single-patch, (2) two-patch, or (3) modified single-patch technique. Of these, the modified single-patch is currently the best technique available for repair of CAVC. The goal of this review is to describe our experience with the modified single-patch technique and explain how it evolved into our procedure of choice for repair of CAVC in our pediatric population...

BACKGROUND: Although adequacy of repair after congenital heart surgery is a crucial determinant of clinical outcome, there is no current method of assessment. We sought to develop a process to measure the adequacy of repair for a diverse group of congenital heart procedures. METHODS: Selected surgical procedures, consisting of repair of ventricular septal defect (VSD), tetralogy of Fallot (TOF), complete common atrioventricular canal (CAVC), and arterial switch operation, were divided into component subprocedures, each of which was assessed separately...

REVIEW
Raffaele Calabrò, Giuseppe Limongelli
Complete atrioventricular canal (CAVC), also referred to as complete atrioventricular septal defect, is characterised by an ostium primum atrial septal defect, a common atrioventricular valve and a variable deficiency of the ventricular septum inflow. CAVC is an uncommon congenital heart disease, accounting for about 3% of cardiac malformations. Atrioventricular canal occurs in two out of every 10,000 live births. Both sexes are equally affected and a striking association with Down syndrome was found. Depending on the morphology of the superior leaflet of the common atrioventricular valve, 3 types of CAVC have been delineated (type A, B and C, according to Rastelli's classification)...
