Left-to-right shunting in common congenital heart defects: which patients are eligible for percutaneous interventions?
Atrial septal defects, atrio-ventricular septal defects, ventricular septal defects and the persistent arterial duct are the most common congenital heart defects which may cause, in the presence of a significant left-to-right shunt, chronic volume overload of the heart and lead to the development of pulmonary arterial hypertension. Repair is indicated to avoid these complications and evolution to right-to-left shunting (Eisenmenger syndrome). Although the long-term results of surgical interventions in uncomplicated congenital heart defects were excellent, percutaneous techniques to repair the defects became a focus of attention. The persistent arterial duct, the secundum type atrial septal defect, and, more recently, the muscular and perimembranous ventricular septal defect are currently eligible for percutaneous closure. By avoiding a sternotomy or a thoracotomy, complaints of pain become exceptional and the duration of hospitalisation is shortened. Percutaneous closure is not only better tolerated than surgery, it may also imply favourable economical aspects.
