device closure
Minimally invasive catheterization procedure using occluder devices to close abnormal communications between heart chambers or vessels.
Full Definition
Device closure refers to transcatheter procedures that use specially designed occluder devices to seal abnormal communications in the heart or great vessels. Common applications in pediatric cardiology include closure of atrial septal defects, ventricular septal defects, patent ductus arteriosus, and patent foramen ovale. The procedure involves advancing the device through a catheter system and positioning it across the defect, where it expands to provide immediate closure. Various device types are available, including umbrella devices, coils, and plug devices, each designed for specific anatomical configurations. Device closure offers an alternative to surgical repair for appropriately selected lesions, with advantages including shorter recovery time, no sternotomy, and reduced morbidity.
Usage
Usage note: Specify device type and manufacturer when documenting procedures; not all defects are suitable for device closure.
