Abstract:
Atrial septal defect (ASD) is a congenital heart disease often encountered in the adult population, as it is frequently asymptomatic in childhood. In untreated patients with ASD, some may go on to develop complications such as atrial arrythmias, pulmonary hypertension and Eisenmenger syndrome. Pulmonary hypertension is seen in 6 - 35% of this group of untreated patients in adulthood as a result of left-to-right shunting. Symptoms of pulmonary hypertension include progressive dyspnoea, ascites and syncope. Here, we would like to illustrate a case of ASD presenting with recurrent syncopal attack.
