Device Closures
Types of Device Closures
Atrial Septal Defect (ASD) Closure
ASD: A hole in the septum between the heart's two upper chambers (atria).
Procedure: A catheter is inserted through a blood vessel and guided to the heart. The device (often a double-disc structure) is deployed to cover the hole, sealing it over time as tissue grows around it.
Ventricular Septal Defect (VSD) Closure
VSD: A hole in the septum between the heart's two lower chambers (ventricles).
Procedure: Similar to ASD closure, a catheter delivers a closure device to the site of the defect to plug the hole.
Patent Ductus Arteriosus (PDA) Closure
PDA: A persistent opening between the aorta and the pulmonary artery, which should close shortly after birth.
Procedure: A catheter is used to place a closure device in the ductus arteriosus to block abnormal blood flow.
Advantages of Device Closures
Minimally Invasive: Reduced risk compared to open-heart surgery, shorter recovery time, and less scarring.
Reduced Hospital Stay: Most patients can return home within a day or two.
Faster Recovery: Quicker return to normal activities.
Procedure Details
Preparation
Imaging Tests: Echocardiography, MRI, or CT scans to assess the defect.
Medication: Pre-procedural medications such as antibiotics or antiplatelets may be given.
Procedure
Access: A catheter is inserted through a vein (often in the groin) and guided to the heart.
Device Deployment: The closure device is positioned across the defect using real-time imaging (e.g., fluoroscopy, echocardiography).
Confirmation: Proper placement is confirmed, and the device is released to close the defect.
Post-Procedure Care
Monitoring: Patients are monitored for any immediate complications.
Medications: Antiplatelet therapy may be continued for a few months to ensure proper healing and device integration.
Follow-Up: Regular follow-up visits and imaging to check the device position and heart function.
