Case Information: A 17-year-old male patient was diagnosed with congenital heart disease with a secundum atrial septal defect (ASD). Echo revealed a 9mm echogenic defect in the mid-atrial septum and soft margin defect is approximately 14mm in size. The defect is 9mm from the mitral valve and 3mm from the aortic side.
Clinical Strategy: During the procedure, intraoperative ICE ultrasound was used to reassess the defect size, measuring 9.83mm with a soft margin. Given the patient's young age and comprehensive evaluation, we selected the BDASD-I 16 (waist diameter is 16mm) biodegradable ASD occluder as the optimal solution for this case.
Case Summary: In the field of interventional cardiology, intracardiac echocardiography (ICE) has become an invaluable tool, offering high-resolution, real-time imaging to precisely visualize defects. In this case, ICE and TTE were used from multiple views and angles to confirm the positioning of the double-disc occluder, ensuring that it was properly bridged across both sides of the septum. Upon release, the occluder was observed to be securely attached to the septum with no residual shunt, allowing for an efficient and successful closure.
This case highlights the synergy between ICE technology and biodegradable occluders, ensuring highly effective outcomes in complex ASD interventions.
