Final answer:
Only certain types of ASDs can undergo percutaneous repair, while others require surgical repair.
Step-by-step explanation:
Percutaneous Repair of Atrial Septal Defects (ASDs)
Only certain types of ASDs can undergo percutaneous repair, while others require surgical repair. Percutaneous repair involves using catheter-based techniques to close the defect without the need for open-heart surgery. Typically, small to moderate-sized ASDs with suitable characteristics are eligible for percutaneous repair.
Example:
One example of an ASD that can be repaired percutaneously is a secundum ASD. This is the most common type of ASD and is located in the middle of the atrial septum. Other types of ASDs, such as primum ASDs or sinus venosus ASDs, may require surgical repair.
