BACKGROUND: There is a paucity of data regarding late-onset pulmonary hypertension (PH) in patients with transposition of the great arteries and atrial switch surgery. METHODS AND RESULTS: A retrospective cohort study was conducted on 140 adults with transposition of the great arteries and atrial switch surgery, age 37.3±7.8, 37.1% female, in order to assess the prevalence and characteristics of late-onset PH and explore associated factors. Patients were followed for a median of 32...

Aim: Intra-atrial re-entrant tachycardia (IART) is a common complication in patients with congenital heart disease (CHD) and is related to increased morbidity and mortality. Few reports have been published about factors associated to IART severity. The aim of this study is to analyse factors associated to severe clinical presentation of IART. Methods and Results: Observational study of all consecutive CHD patients who underwent a first IART ablation from January 2009 to December 2015 (94 patients, 39...

Congenitally corrected transposition of great vessels (CCTGV) is a rare congenital heart disease (CHD) accounting for <1% of CHDs. CCTGV with infundibular pulmonary stenosis (PS) with ventricular septal defect (VSD) is part of Fallot's physiology. It is known to be associated with bradyarrhythmias like atrioventricular (AV) blocks, and acquired complete AV block occurs at a rate of 2% per year. Patients can have left-sided accessory pathways, which may cause atrioventricular reentrant tachycardia (AVRT)...

Gene duplication (GD), thought to facilitate evolutionary innovation and adaptation, has been studied in many phylogenetic lineages. However, it remains poorly investigated in trematodes, a medically important parasite group that has been evolutionarily specialized during long-term host-parasite interaction. In this study, we conducted a genome-wide study of GD modes and contributions in Schistosoma mansoni, a pathogen causing human schistosomiasis. We combined several lines of evidence provided by duplicate age distributions, genomic sequence similarity, depth-of-coverage and gene synteny to identify the dominant drivers that contribute to the origins of new genes in this parasite...

OBJECTIVE: To develop quality metrics (QMs) for the ambulatory care of patients with transposition of the great arteries following arterial switch operation (TGA/ASO). DESIGN: Under the auspices of the American College of Cardiology Adult Congenital and Pediatric Cardiology (ACPC) Steering committee, the TGA/ASO team generated candidate QMs related to TGA/ASO ambulatory care. Candidate QMs were submitted to the ACPC Steering Committee and were reviewed for validity and feasibility using individual expert panel member scoring according to the RAND-UCLA methodology...

OBJECTIVE: To describe a new sonographic marker of transposition of great arteries (TGA) during the first trimester screening. METHODS: We reviewed six cases of TGA from 2013 to 2016 which an antenatal diagnosis of TGA at first trimester screening (11-13 + 6 weeks of gestation) was confirmed postnatally. We specifically assessed images obtained by scanning the fetal heart in three vessels (3V) and three-vessel with trachea (3VT) views using color Doppler. The "reverse boomerang" sign was defined as a reverse curvature of right ventricle outflow tract (RVOT) at level of the three-vessel with trachea (3VT) view...

OBJECTIVE: To determine whether children who underwent surgery for congenital heart disease (CHD) are as fit as their peers. STUDY DESIGN: We studied 66 children (6-14 years) who underwent surgery for ventricular septal defect (n = 19), coarctation of aorta (n = 10), tetralogy of Fallot (n = 15), and transposition of great arteries (n = 22); and 520 healthy children (6-12 years). All children performed physical fitness tests: cardiorespiratory fitness, muscular strength, balance, flexibility, and speed...

The success of the arterial switch operation mostly depends on the proper relocation of the coronary arteries. This involves more than the simple suturing of the coronary cuff to the neo-aortic root, it also involves the preparation of the landing zone and the correct mobilisation of the primary coronary branches. In this tutorial, we present our technique for correction of a dextro-transposition of the great arteries with a normal, type A, coronary artery pattern.

Intramural coronary arteries in patients with d-transposition of the great arteries (d-TGA) usually arise from the opposite sinus of Valsalva and traverse horizontally across the posterior/facing commissure before emerging externally from the appropriate sinus of Valsalva. Failure to make appropriate technical modifications during coronary transfer can result in an important risk of posttransfer ischemia. We report a case with an unusual course of an intramural left anterior descending (LAD) coronary artery in a patient with d-TGA, with origin at the mid ascending aorta and a vertical intramural course, increasing the susceptibility to injury during an arterial switch operation (ASO)...

Azithromycin (AZM) is a clinically important antibiotic to Vibrio cholerae especially for inhibiting colonization of V. cholerae in intestine and the treatment of severe cholera in children and pregnant women. One IncA/C plasmid was isolated from both of the high MIC AZM resistant V cholerae strains of the two mainly pathogenic serogroups, O1 and O139. In the 172 predicted ORFs, 16 genes were related to antibiotic resistance in which 5 were well-defined genes associated with macrolide resistance. The 5 macrolide resistant genes disturbed in two clusters, mphR-mrx-mph(K) and mel-mph2, flanking by insertion sequence (IS) and involving two kinds of mechanisms...

We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

OBJECTIVE: To assess the trajectory of perioperative brain growth in relationship to cardiac diagnosis and acquired brain injuries. METHODS: This was a cohort study of term neonates with hypoplastic left heart syndrome (HLHS) and transposition of the great arteries (TGA).

Patients with childhood heart disease are living longer and entering adulthood, and may undergo implantable cardioverter-defibrillator (ICD) implantation to reduce the risk of sudden death. We evaluated the characteristics of adult patients with congenital heart disease or left ventricular noncompaction cardiomyopathy (LVNC) in the National Cardiovascular Disease Registry ICD Registry and determined ICD-related in-hospital complications. Patients with LVNC or transposition of the great arteries, tetralogy of Fallot, Ebstein's anomaly, atrial septal defect, ventricular septal defect, or common ventricle were identified in the registry...

Four-dimensional (4-D) flow magnetic resonance imaging (MRI) examination was performed 25 years after a neonatal direct arterial switch operation for simple transposition of the great arteries. The 4-D flow MRI video shows physiological spiral anatomical configuration and laminar streamlines in the great arteries.

BACKGROUND: Atrial tachycardias (ATs) are a significant source of morbidity in adults with congenital heart disease (CHD). This study evaluates the incidence and clinical predictors of AT in a cohort of patients with CHD. METHODS AND RESULTS: We included 3311 adults (median age at entry 22.6 years, 50.6% males) with CHD (49% simple, 39% moderate, and 12% complex) prospectively followed up in a tertiary center for 37 607 person-years. Predictors of AT were identified by multivariable Cox regression analysis accounting for left truncation...

BACKGROUND: Tunneled transposition of the facial artery myomucosal (FAMM) island flap on the lingual side of the mandible has been reported for intraoral as well as oropharyngeal reconstruction. This modified technique overcomes the limitations of short range and dentition and further confirms the flexibility of the flap. This paper presents a case of reconstructing secondary soft palatal defect due to flap necrosis following two-flap palatoplasty in irradiated patient with lingually transposed facial artery myomucosal island flap...
