Aorto-left atrial fistula post-percutaneous device ASD closure.

Use of percutaneous devices for closure of atrial septal defects (ASD) continues to increase owing to relative safety and ease of implementation compared with traditional surgical repair. Complications such as perforation and displacement requiring surgical intervention have been reported. We describe a case of perforation with intracardiac fistula formation, with an underlying mechanism likely to be similar to the few cases previously described, occurring during medium term follow up after ASD device closure. Appropriate case selection can reduce the incidence of this complication with caution taken in ASD cases with deficient aortic and superior rims.
