ASD/VSD/PDA/Collateral Device Closures

Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD) and Patent Ductus Arteriosus (PDS) are congenital birth defects diagnosed in children but can be found in grownups at a later stage. Under these conditions, the blood flows from left side of the heart to the right, mounting a lot of workload on the heart.

Advanced closure methods with the help of catheters also known as device closures come in handy in treating these life-threatening ailments without going for an open-heart surgery. In this technique, a catheter gets inserted via groin and then guided to the heart. After reaching the defect, an umbrella like device gets placed on the defect. The device not only corrects the blood flow but closes the defect over a period of time.

 

Coil Closure Of PDA/Mapcas

Patent Ductus Arteriosus or PDA is a medical condition in which ductus arteriosus or ductus botalli, a blood vessel connecting pulmonary artery to the proximal descending aorta in the developing foetus fails to close after birth. As a result, a portion of oxygenated blood from the left heart flows back to the lungs causing pulmonary hypertension, right-sided heart failure, loss of weight gain, heavy breathing etc in the child.

Major Aortopulmonary Collateral Occlusion is an ailment under which the bronchial arteries that supply blood to the lungs are underdeveloped. These arteries can eventually become stenotic and narrowed and if not attended immediately, can lead to congestive heart failure.

Coil closure of PDA/MAPCAs is done to close the opening between the aorta and pulmonary artery in a child. During the procedure a catheter will be inserted through the groin, neck or arm under the general anaesthesia. The expert paediatric cardiac surgeon then would use 1 or more coils to close the Patent Ductus Arteriosus or (PDA). The catheter gets removed after completing the procedure.

In case of MAPCAs, the similar procedure is followed but it is aimed at grouping the collateral arteries and converting the supply of deoxygenated blood from right side of the heart.

 

Balloon Pulmonary/ Aortic Valvuloplasty:

Balloon Pulmonary or Aortic Valvuloplasty is a technique to cure congenital pulmonary stenosis in which the pulmonary valve fails to open completely. As a result, the child’s heart would suffer from overworked heart and severe symptoms like chest pain, shortness of breath, fatigue and fainting.

Balloon Pulmonary Valvuloplasty is a procedure under the expert inserts a catheter through the groin, to access the pulmonary valve, after which a balloon at the tip of the wire or catheter gets inflated stretching the valve and helping it to open. It facilitates the blood flow to the pulmonary artery without any obstruction.

 

LPA/PDA/Coarctation of Aorta: Balloon Dilation and Stenting:

Patent Ductus Arteriosus or PDA is a medical condition in which ductus arteriosus or ductus botalli, a blood vessel connecting pulmonary artery to the proximal descending aorta in the developing foetus fails to close after birth.

Coarctation of Aorta is narrowing of the aorta and these both conditions are present at the birth.

The treatment usually involves balloon angioplasty often coupled with stenting for treating the narrowing down of aorta. The doctor during the procedure would insert a thin, catheter through the groin of the child and the balloon at the tip opens the narrowed aorta. Once inflated, the aorta gets widened, facilitating the normal blood flow.

In some cases, the doctors may use a metal mesh or a stent into aorta to prevent it from blocking again. The same procedure is followed in the case of Patent Ductus Arteriosus too but the opening will be closed with the help of catheter.
