Pediatric Cardiac Surgery in India - Aortic Stenosis Surgery in children

Pediatric Cardiac Surgery is the heart surgery performed on infants, children and adolescents.  A successful pediatric cardiac surgery not only requires cutting edge technology and an interdisciplinary team of expert heart surgeons, it requires a whole lot of team work from hospital staff and nurses  and a lot of people involved to deliver a comprehensive cardiac care to the child.

The pediatric heart surgery corrects a spectrum of life threatening heart diseases and abnormalities present since birth called as congenital heart defects. Some heart surgeries are also performed while the child is still in the womb. Thus pediatric cardiac surgery requires expertise of surgeons as well as an uncompromised quality of care for a successful outcome.

Cardiac Defects in children

Congenital Heart Defect is a defect present in the structure or great vessels of the heart since birth. The major cause of heart defects are either because of obstruction of blood flow in the heart or its vessels or due to abnormal pattern of blood flow through the heart.

The defect in the heart leads to mixing of pure and impure blood or reduced blood flow through the heart which leads to bluish discoloration of body or cyanosis. The signs and symptoms of cardiac defects depend upon the type and severity of heart defect. Some of the associated signs and symptoms of congenital heart defect are – syncope, heart murmur, under development of limbs and muscles, respiratory infections etc.

An overview of congenital heart diseases:

Aortic Stenosis – Aortic Stenosis is a congenital heart defect in which there is obstruction of blood flow from heart to the body. In the normal heart, blood flows from the lungs to the upper left chamber of the heart called as left atrium. The blood from left atrium flows through the mitral valve to the left ventricle. The blood is then pumped through aortic valve to the body. In Aortic stenosis, the area where blood exits the heart’s lower left chamber becomes narrow which causes obstruction of blood flow from heart to the body. Sometimes, the aortic valve itself is affected called as valvular aortic stenosis or there is fusion of the valve leaflets, the condition is called as bicuspid aortic valve.

With trivial or mild aortic stenosis, heart related symptoms are not expected in children but moderate to severe aortic stenosis causes symptoms such as chest pain during exercise, palpitations, palpitation, dizziness, fainting etc.

Diagnosis of Aortic Stenosis

·         Physical examination – The diagnosis of aortic stenosis is usually made with the presence of heart murmur. There could be symptoms of congestive heart failure along with weak pulses in the infants with aortic valve stenosis.

·         Medical Examination – Medical Examination is done by an echocardiogram. The pre-natal diagnosis of aortic valve stenosis is done by an echocardiogram as early as by 16th week of pregnancy. The echo-cardiogram is done during a routine prenatal ultrasound or when there is family history of congenital heart disease. Cardiac Catheterization is also done for the purpose of diagnosis or for therapeutic purpose, for instance, to perform angioplasty or balloon dilatation.

Treatment of Aortic Stenosis

1.       Surgery for valvular aortic stenosis:
  • ·         Surgical valvotomy
  • ·         Valve Replacement Procedure
  • ·         Ross procedure
  • ·         Mechanical valve replacement
2.       Surgery for sub-valvular aortic stenosis
3.       Surgery for supravalvular aortic stenosis
4.       Balloon angioplasty for valvular aortic stenosis

It is called triple bypass because the number of grafts done in this procedure is three. It is important to understand CABG (Coronary Artery Bypass Graft) or heart bypass surgery first, to understand what triple heart bypass surgery is.
The arteries that supply blood to the heart for its functioning are called Coronary arteries. Any block in the coronary artery may lead to the disruption in the normal working (pumping of blood to the body) of the heart and lead to a heart attack.  The blockage in the coronary arteries is referred to as coronary artery disease and if it is severe, the blood flow to the heart can be completely stopped which can be fatal. 
This blockage can be treated by medicine alone if the blockage is small, but if the blockage is severe, one would require a heart bypass surgery or a CABG( Coronary Ar…
