Device Closures
Device closures are minimally invasive cardiac procedures that use specialized devices to close abnormal openings or defects within the heart. These techniques are performed using catheter-based approaches and serve as a safer, less invasive alternative to open-heart surgery. Commonly treated defects include Atrial Septal Defects (ASDs), Ventricular Septal Defects (VSDs), and Patent Ductus Arteriosus (PDA).

Types of Device Closures
1. Atrial Septal Defect (ASD) Closure
Definition: An ASD is a hole in the wall (septum) between the heart’s two upper chambers (atria).
Procedure: A catheter is inserted through a blood vessel (usually in the groin) and guided to the heart. A special double-disc closure device is then deployed to cover and seal the hole. Over time, heart tissue naturally grows around the device.
2. Ventricular Septal Defect (VSD) Closure
Definition: A VSD is a hole in the septum separating the two lower chambers (ventricles) of the heart.
Procedure: Similar to ASD closure, a catheter is used to position a closure device at the defect site, effectively blocking the abnormal blood flow between the ventricles.
3. Patent Ductus Arteriosus (PDA) Closure
Definition: A PDA is a persistent connection between the aorta and pulmonary artery that normally closes soon after birth.
Procedure: A catheter is used to deliver and deploy a closure device within the ductus arteriosus, stopping the abnormal blood circulation.
Advantages of Device Closures
Minimally Invasive: Eliminates the need for open-heart surgery, resulting in fewer complications and smaller scars.
Short Hospital Stay: Most patients are discharged within 24–48 hours.
Quick Recovery: Enables faster return to normal daily activities.
Reduced Pain and Risk: Lower risk of infection and postoperative discomfort.
Procedure Details
Preparation:
Imaging: Tests such as Echocardiography, CT scan, or MRI help determine the defect’s size and location.
Medication: Patients may be prescribed antibiotics or antiplatelet medications before the procedure.
During the Procedure:
Access: A thin catheter is inserted through a vein in the groin and guided to the heart.
Device Deployment: Using fluoroscopy (X-ray guidance) and echocardiography, the doctor positions the closure device across the defect.
Confirmation: The device’s position is verified, and it is released to permanently seal the defect.
Post-Procedure Care
Monitoring: Patients are observed for a few hours or overnight for any complications.
Medication: Antiplatelet therapy may be prescribed for several months to promote proper healing.
Follow-Up: Regular check-ups with Echocardiography ensure the device remains well-positioned and heart function is normal.
