Atrioventricular septal defects constitute 4% of all congenital cardiac malformations. Patients with complete atrioventricular septal defect rarely survive for decades without surgical treatment. Pulmonary stenosis can provide a delicate balance between the pulmonary and systemic circulations and thereby increase longevity. We present the case of a 49-year-old woman whose complete atrioventricular septal defect and associated pulmonary stenosis were diagnosed only after she had given birth to 10 live children through uneventful spontaneous delivery. We discuss her successful surgical treatment in terms of the available medical literature.

Background: In patients with adult congenital heart disease (ACHD), significant atrioventricular valve regurgitation is an important risk factor for poor outcomes, such as heart failure. However, in many cases, transcatheter intervention may reduce the risk profile to avoid a high surgical risk.
Case Summary: A 44-year-old man with complex ACHD in the form of a double-inlet left ventricle, congenitally corrected transposition of the great arteries, pulmonary atresia, atrial septal defect, and patent ductus arteriosus was referred for the treatment of severe tricuspid regurgitation.

Background: Aortic arch obstruction and/or coarctation of aorta is uncommon (5-20%) in balanced atrioventricular septal defects. Although technically challenging, prenatal diagnosis of aortic arch obstruction in atrioventricular septal defect is critical for delivery planning and improves prenatal counselling regarding the timing of cardiac surgery. We sought to identify prenatal predictors of coarctation of aorta in atrioventricular septal defect.

Reoperations can be challenging for patients who experience left and right atrioventricular valve failure after repair of a complete atrioventricular septal defect. Herein, we present a case of a 10-year-old boy who developed dysfunction in left and right atrioventricular valve following surgery for a complete atrioventricular septal defect. The patient underwent successful replacement of his left atrioventricular valve with a mechanical valve due to severe stenosis.

In the past two decades there has been rapid development in the field of computational cardiac models. These have included either (i) mechanical models that assumed simultaneous myocardial activation, or (ii) electromechanical models that assumed time-varying myocardial activation. The influence of these modelling assumptions of myocardial activation on clinically relevant metrics, like myocardial strain, commonly used for validation of cardiac models has yet to be systematically examined, leading to uncertainty over their influence on the predictions of these models.

•Percutaneous repair of severely regurgitant atrioventricular valves in the setting of a Fontan circulation utilizing Tri-Clip, even in the setting of an atrioventricular septal defect, is feasible.•Percutaneous options hold promise as a low-risk repair strategy in this highly complex population, which generally has a high surgical risk.
