Congenital heart disease

OBJECTIVES: To evaluate the safety, feasibility, and efficacy of the MVP™ microvascular plug(Covidien) for closure of vascular anomalies in patients with congenital heart diseases (CHD). BACKGROUND: The MVP™ is a novel device with PTFE integrated. The device has been recently introduced in the radiological field and reported exclusively for neurological anomalies. METHODS: All CHD patients receiving the device from April 2015 until July 2015 were included in the study and followed up clinically as well as by transthoracic echocardiography...

PURPOSE: This study aimed to measure parents' readiness for discharge from a pediatric cardiology/cardiac surgical inpatient unit. DESIGN AND METHODS: An observational study was conducted at a single tertiary care pediatric cardiac surgical program; parents received teaching from a discharge coordinator, bedside nurse, and, if needed, dietician and pharmacist. We surveyed parents/guardians on the day of discharge and 2 weeks later. RESULTS: We enrolled 181 participants, 53% with children <12 months of age...

AIMS: To describe the outcomes of pregnancy in women with pulmonary hypertension. METHODS AND RESULTS: In 2007 the European Registry on Pregnancy and Heart Disease was initiated by the European Society of Cardiology. Consecutive patients with all forms of cardiovascular disease, presenting with pregnancy, were enrolled with the aim of investigating the pregnancy outcomes. This subgroup of the cohort included 151 women with pulmonary hypertension (PH) either diagnosed by right heart catheterization or diagnosed as possible PH by echocardiographic signs, with 26% having pulmonary arterial hypertension (PAH), in three subgroups: idiopathic (iPAH), associated with congenital heart disease (CHD-PAH), or associated with other disease (oPAH), and 74% having PH caused by left heart disease (LHD-PH, n = 112)...

Postoperative junctional ectopic tachycardia (JET) is a narrow complex tachycardia and most frequently occurs during and after surgical repair of certain types of congenital heart defects. Postoperative junctional ectopic tachycardia may produce unfavorable hemodynamics that prolongs stays in the cardiac intensive care unit and hospital, prolongs time on a ventilator, and occasionally requires the use of extracorporeal membrane oxygenation (ECMO) as rescue therapy. The present report describes a rare case of late-onset postoperative junctional ectopic tachycardia, which occurred 13 days after the deployment of a perimembranous ventricular septal defect (PmVSD) occluder in a 17-year-old female teenager...

Congenital cardiovascular malformations are the most common birth defects, with a complex multifactorial etiology. Genetic factors play an important role, illuminated by numerous cytogenetically visible abnormalities, as well as submicroscopic genomic imbalances affecting critical genomic regions in the affected individuals. Study of rare families with Mendelian forms, as well as emerging next-generation sequencing technologies have uncovered a multitude of genes relevant for human congenital cardiac diseases...

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive genetic disorder. It is characterized by heterogeneous clinical manifestations including primary features of the disease (rod-cone dystrophy, polydactyly, obesity, genital abnormalities, renal defects, and learning difficulties) and secondary BBS characteristics (developmental delay, speech deficit, brachydactyly or syndactyly, dental defects, ataxia or poor coordination, olfactory deficit, diabetes mellitus, congenital heart disease, etc.); most of these symptoms may not be present at birth but appear and progressively worsen during the first and second decades of life...

Common arterial trunk with associated double aortic arch is a very rare constellation of congenital heart disease. Prenatal diagnosis allows for surgical repair prior to development of respiratory morbidity, which is otherwise described in all cases with this association.

Prenatal diagnosis of tetralogy of Fallot remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3-vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of tetralogy of Fallot. In addition, we compared its sensitivity to that of the traditional outflow tract views for detection of tetralogy of Fallot. We found that both views were abnormal in all fetuses with tetralogy of Fallot, showing reversed aortic-to-pulmonary valve and aortic arch isthmus-to-ductus arteriosus ratios in the outflow tract and 3-vessel and trachea views, respectively...

BACKGROUND: Echocardiographic parameters of ventricular deformation of the systemic right ventricle (sRV) predict adverse clinical outcome in patients after atrial repair of transposition of the great arteries (TGA). We assessed myocardial deformation on cardiac MRI (CMR) and correlated these with clinical and conventional CMR parameters in TGA patients. METHODS: Retrospective analysis of CMR studies in 91 TGA patients (66% male; mean age 30.1±5.1years) at two tertiary adult congenital heart centers was conducted...

BACKGROUND: Because of advancements in care, there has been a decline in mortality from congenital heart defects (CHDs) over the past several decades. However, there are no current empirical data documenting the number of people living with CHDs in the United States. Our aim was to estimate the CHD prevalence across all age groups in the United States in the year 2010. METHODS: The age-, sex-, and severity-specific observed prevalence of CHDs in Québec, Canada, in the year 2010 was assumed to equal the CHD prevalence in the non-Hispanic white population in the United States in 2010...

Over the past 20 years, the successes of neonatal and infant surgery have resulted in dramatically changed demographics in ambulatory cardiology. These school-aged children and young adults have complex and, in some cases, previously unexpected cardiac and non-cardiac consequences of their surgical and/or transcatheter procedures. There is a growing need for additional cardiac and non-cardiac subspecialists, and coordination of care may be quite challenging. In contrast to hospital-based care, where inpatient care protocols are common, and perioperative expectations are more or less predictable for most children, ambulatory cardiologists have evolved strategies of care more or less independently, based on their education, training, experience, and individual styles, resulting in highly variable follow-up strategies...

BACKGROUND: The National Quality Forum previously approved a quality indicator for mortality after congenital heart surgery developed by the Agency for Healthcare Research and Quality (AHRQ). Several parameters of the validated Risk Adjustment for Congenital Heart Surgery (RACHS-1) method were included, but others differed. As part of the National Quality Forum endorsement maintenance process, developers were asked to harmonize the 2 methodologies. METHODS AND RESULTS: Parameters that were identical between the 2 methods were retained...

OBJECTIVE: Biomarkers play a pivotal role in heart failure (HF) management. Reference values and insights from studies in adults cannot be extrapolated to the paediatric population due to important differences in pathophysiology and compensatory reserve. We assessed the diagnostic utility of four novel biomarkers in paediatric HF. METHODS: Midregional (MR) pro-atrial natriuretic peptide (proANP), soluble ST2 (sST2), growth differentiation factor-15 (GDF-15), MR-pro-adrenomedullin (proADM) and N-terminal pro-B natriuretic peptide (NT-proBNP) were measured in 114 patients and 89 controls...

BACKGROUND: As survival of children with CHD needing surgery has improved significantly, the need for follow-up in terms of health-related quality of life has become increasingly important. In this study, we sought to describe health-related quality of life in children with CHD in relation to cardiac surgery. METHODS: A retrospective Swedish National Registry for Congenital Heart Disease survey measured using DISABKIDS chronic generic measure-short version included 337 children (age 9-17 years; 39% girls)...

BACKGROUND: Transcatheter patent ductus arteriosus (PDA) occlusion is feasible in small infants and may improve lung function in symptomatic patients. We aimed to describe transcatheter PDA closure in small infants including predictors of technical success and rate of complication and to identify factors associated with improved respiratory status after closure. METHODS: All patients in the NICU at our center who were referred for transcatheter PDA occlusion between 1/2010 and 11/2014 were retrospectively identified...

Fontan failure has been variably and inconsistently described in the literature, leading to challenges in comparing studies and evaluating treatments. Development of a conceptual framework to describe clinical phenotypes will aid in consistent terminology in the literature. In the heart failure literature, several key concepts have been described-"heart failure" is a clinical syndrome of various etiologies, with phenotype-specific response to therapies. As the congenital heart disease community struggles to grapple with "Fontan failure," these concepts come to light...

BACKGROUND: Recently, there has been an increasing number of internal medicine-trained electrophysiologists who choose not to test for acute defibrillation efficacy during implantable cardioverter defibrillator (ICD) implantation. It is not known whether this same trend is seen in pediatric electrophysiologists, who care primarily for patients with congenital heart disease or primary electrical problems. METHODS: Through a 14-question survey created on Survey Monkey, we asked the members of the Pediatric and Adult Congenital Electrophysiology Society (PACES) for their approach to ICD implantation...

As physicians and caregivers of children with congenital heart disease, we are aware of the increasing need for procedures requiring anesthesia. While these procedures may be ideal for medical and cardiac surgical management, the risks and benefits must be assessed carefully. There are well known risks of cardiovascular and respiratory complications from anesthesia and sedation and a potentially under-appreciated risk of neurocognitive dysfunction. Both animal and human studies support the detrimental effects of repeated anesthetic exposure on the developing brain...
