BACKGROUND: We summarize the evidence for an association between congenital heart defects and prenatal brain growth through a systematic literature review. Congenital heart defects are among the most common malformations, affecting approximately six per 1000 live births. The association between congenital heart defects and long-term neurodevelopmental disorders is well established. Increasing evidence suggests an association between impaired prenatal brain growth and neurodevelopmental disorders in children with congenital heart defects...

We report the placement of a permanent transvenous nonselective His bundle pacing lead in conjunction with a transvenous pacemaker/ICD in an adult with Levo-Transposition of the Great Arteries (L-TGA) and a stenotic coronary sinus (CS) ostium (os), which would not accommodate a transvenous LV pacing lead. Nonselective His bundle pacing provided a nearly identical ventricular activation pattern in this previously unpaced patient. Many L-TGA patients will have an eventual need for permanent pacing and, given the challenges of CS cannulation, His bundle pacing may represent a preferred modality rather than pure morphologic LV pacing or surgical systemic ventricular lead placement to achieve optimal electrical synchrony...

PURPOSE OF REVIEW: Patients with complete and congenitally corrected transposition of the great arteries commonly survive into adulthood and present with a vast array of clinical residua. RECENT FINDINGS: Echocardiography remains the primary imaging modality in the routine assessment of the adult with transposition of the great arteries. It provides a comprehensive anatomic and hemodynamic evaluation. Limitations to echocardiography include evaluation of the following: the systemic right ventricle, baffle patency following atrial switch procedure, coronary arteries following arterial switch procedure or Nikadoh, and multilevel right ventricular outflow tract obstruction...

BACKGROUND: The Fontan circulation, a result of a palliative procedure in patients with single systemic ventricles, is defined by chronically elevated pulmonary vascular resistance. When traditional heart failure therapies fail, pharmacological agents that reduce pulmonary artery pressures may be used. These include endothelial-receptor antagonists, prostanoids and phosphodiesterase type 5 inhibitors. We report the first use of macitentan, an endothelin-receptor antagonist, in a patient with a Fontan circulation...

BACKGROUND: The transposition of the great arteries (TGA) is one of the most severe congenital heart diseases. The arterial switch operation (ASO) is the preferred procedure to treat TGA. Although numerous reports have shown good results after ASOs, some patients suffer from circulatory system problems following the procedure. One reason for problems post-ASO is the local changes in the curvature and torsion of the thoracic aorta. OBJECTIVE: The influence of these geometric changes on the blood flow field needs to be investigated in detail to consider possible cardiovascular problems after an ASO...

Adult patients with repaired congenital heart disease are presenting with previously unseen types of residual lesions and consequences of prior repair. Patients with d-transposition of the great arteries repaired with atrial switch operations are returning with dysrhythmias and atrioventricular valve disease requiring intervention. We present the challenging case of a young adult with a residual shunt identified on preoperative three-dimensional transthoracic echocardiography, the precise anatomy of which was only characterized intraoperatively...

REVIEW

The atrial switch operations, the Mustard and Senning procedures, performed for dextro-transposition of the great arteries, have largely been supplanted by the arterial switch operation. As such, affected patients will only exist for approximately 30 more years. The main arrhythmias in these patients include sinoatrial node dysfunction, intraatrial reentry tachycardia, and sudden death. Device therapy for these patients is well-established, and catheter ablation for atrial tachycardias is highly efficacious...

OBJECTIVES: We analysed nationwide early and late results after the Mustard, Senning and arterial switch operation. METHODS: We included all paediatric patients (<18 years) who underwent a Senning, a Mustard or an arterial switch operation for transposition of the great arteries from 1968 to 2009 in Finland. Data were obtained retrospectively from a paediatric cardiac surgical database and population data from the Finnish national registry. RESULTS: Early mortality (<30 days) was 11% after Mustard and 5% after Senning operation, while the rate decreased from 19% during 1976-1999 to 2% during 2000-2009 for arterial switch patients ( P  < 0...

BACKGROUND: D-transposition of the great arteries (D-TGA) is one of the most common critical neonatal heart defects. Although there are clinical advantages to a prenatal diagnosis, D-TGA has had low prenatal detection internationally. Recent obstetrical ultrasound guidelines incorporating screening of cardiac outflows may improve prenatal detection of D-TGA. We sought to evaluate trends in the prenatal detection of D-TGA with/without ventricular septal defect (VSD) in Alberta over the past 13 years, examining the potential impact of enhanced ultrasound guidelines in 2009-2010 and 2013 and factors impacting detection...
