ABSTRACT

In adults, percutaneous closure has become the preferred method for treating most secundum atrial septal defects (ASD) and patent foramen ovales (PFO). This approach has demonstrated safety and effectiveness, offering several benefits over surgical closure. These benefits include avoiding cardiopulmonary bypass and sternotomy, minimizing scarring, reducing hospital stays, and potentially lowering the risk of complications following the procedure. While the procedure itself and short-term outcomes have shown low rates of mortality and morbidity, the widespread use of ASD and PFO closure devices has revealed some rare and delayed complications. Device thrombosis and cardiac erosion are among the most severe late complications, while atrial arrhythmias are the most frequent. Other potential complications include nickel allergies, disturbances in cardiac conduction, damage to heart valves, and device-related endocarditis. Long-term complications, though infrequent, can be sudden and life-threatening. This chapter aims to discuss the types, frequencies, and outcomes of these rare but serious delayed complications associated with device closures.
