Minimally Invasive Surgery for Atrial Septal Defect
A congenital heart disease, Atrial Septal Defect (ASD) is a hole in the wall (septum) between the top two chambers of the heart (the left atrium and the right atrium). In a normal heart, the left atrium contains blood that is high in oxygen and the right atrium contains blood that is low in oxygen. In a heart with ASD, the hole between the left and right atrium causes blood from both chambers to become mixed, leading to improper circulation and oxygenation of the blood.
Minimally invasive surgery can be used to close atrial septal defects, allowing the procedure to be performed through small incisions and without stopping the heart, or separating the breastbone (sternum) and ribcage, or requiring a heart-lung machine to be used.
Using specialized endovascular catheters and trans-esophageal echocardiography, the surgeon accesses the heart through small incisions, or "ports". Because this technique is less traumatic on the patient, recovery time is faster and there are fewer post-operative complications. In some cases, a robot is used to assist the surgeon in performing the minimally invasive procedure.
