ASD/PDA Device Closure
DEVICE CLOSURE
Device Closure is used to close the gap or opening between the right and left sides of the heart. The heart has four chambers. The two upper chambers are called Atria. Atria is separated by a wall called the Atrial Septum. Pulmonary Veins supply Oxygenated Blood to the Left Atrium. The left atrium, in turn, sends this oxygen-rich blood to the Left Ventricle via the Mitral Valve, to transport oxygenated blood to the body.
The walls of the heart are well separated and maintain a good circulatory system. But in some cases where you are born congestive heart failure, if there are holes in the heart, either in the atrial wall or in the ventricle wall, this can lead to disruption of blood circulation leading to heart failure. If the holes are too small, they can be filled with surgery, with some metal parts. This concept is known as DEVICE CLOSURE. So, in a nutshell, in Device Closure, there is a metal device that is surgically placed in a place to occlude the hole and to restore cardiac function.
WHAT IS ASD?
The ASD (atrial septal defect) is a hole in the lining between the two chambers of the heart. The Right Atrium contains Deoxygenated blood and, as such, is sent to the lungs for purification after passing through the Right Ventricle. At Atrial Septal Disorder, there is a small hole in the wall that separates the atria, called the atrial septum. As a result, Oxygen-rich blood leaks from the left atrium to the right leading to recurrent blood flow. As a result, the right atrium is filled with more activity as oxygen-rich and deoxygenated blood clots, resulting in more pressure on the right atrium to send more blood to the lungs.
WHAT IS A PDA?
Patent means ‘open’. And the ductus arteriosus is a common blood vessel. Thus, in short, there is an abnormal opening in the normal blood vessels. In a normal human heart, the Aorta supplies oxygen to the rest of the body and the arteries carry oxygen-free blood to the lungs. Both blood vessels are separate from each other. When a baby is in the womb, there is a small duct that connects the aorta to the artery, which is normal. This tiny passage is called the Ductus Arteriosus. Because; the baby’s lungs begin to function only at birth. It continues to receive pure blood flow from the placenta and its mother. When a baby is born, the ductus arteriosus closes within one day and in some cases, up to one year. An error is detected when the opening is not closed and the Aorta & pulmonary artery still has open communication between you. As a result, oxygen-rich blood from the aorta leaks into the lungs, leading to increased pressure on the lungs.
