Device closures are minimally invasive procedures used to seal abnormal openings in the cardiovascular system. Specialized devices are inserted via catheters to occlude defects such as atrial septal defects.
These interventions offer effective treatment for various conditions, including patent foramen ovale and patent ductus arteriosus, providing patients with a less invasive alternative to traditional surgical approaches.
Patients undergo a thorough evaluation, including medical history review and diagnostic imaging (e.g., echocardiography, angiography) to assess the anatomy and suitability for device closure.
Anesthesia or conscious sedation is administered to ensure patient comfort during the procedure.
A catheter is inserted into a vein or artery, typically in the groin area, and guided to the site of the defect or abnormal opening under fluoroscopic guidance.
The closure device, selected based on the type and location of the defect, is advanced through the catheter and positioned at the site of closure.
Imaging techniques such as fluoroscopy or echocardiography are used to confirm proper device positioning and alignment with the defect.
The closure device is deployed, allowing it to expand and securely seal off the defect or abnormal opening.
Additional imaging may be performed to assess the effectiveness of the closure device and ensure complete closure of the defect.
Patients are monitored in a recovery area for any immediate complications, such as bleeding or arrhythmias, before being discharged with instructions for post-procedural care. Follow-up appointments are scheduled to assess device function and monitor for any complications.
Device closures are utilized across various medical specialties, including cardiology, interventional radiology, pediatric cardiology, and cardiovascular surgery. These closures involve the use of specialized devices to occlude or seal off abnormal openings or defects within the cardiovascular system, such as atrial septal defects (ASDs), patent foramen ovale (PFO), and vascular malformations.
