Congenital Heart Disease is a defect within the heart structure and more commonly present at birth. The severity of the disease varies from mild defects to severe and life-theatening conditions. According the the birth defect registry it was reported from 1994 till the year 2000, congenital heart disease was a factor in 0.81% of total live births.
According to Health Indicator 2007 by the Malaysian Department of Statistics, there were about 500,000 child deliveries in Malaysia in a year. Incidences of congenital heart disease is estimated at about 5,000 per year, of which two thirds will require surgical interventions in the first year of life. About 400 children under the age of 5, with congenital heart disease died in the year 2016. In addition, over 25,000 youth are reported to be suffering from this disease.
There are many types of Congenital Heart Disease such as:
- Atrial Septal Defect (hole in the wall separating the two upper, right and left, atriums of the heart)
- Coarctation of the aorta
- Fallot's Tetralogy
- Hole in the heart
- Mitral Valve Prolapse
- Patent Ductus Arteriosus
- Pulmonary Artesia
- Pulmonary / Aortic Stenosis
- Transposition of the great vessels
- Ventricular Septal Defect (hole in the wall separating the right and left ventricles)
The cause for Congenital Heart Disease is yet to be fully understood, however they might include:
Chromosomal or genetic conditions, which can be inherited or might occur once in a while during early pregnancy:
- Down Syndrome, DiGeorge Syndrome, Marfan Syndrome and Turner Syndrome
- Environmental factors can lead to congenital heart disease:
- Excessive drug or alcohol consumption during pregnancy, acne medications, exposure to chemicals, viral infections (e.g. rubella), and other diseases including diabetes
Many congenital heart defects show no signs or symptoms.If multiple heart defects are detected in newborns, certain symptoms might appear:
- Blue skin, lips, and fingernails
- Chest pain
- Fainting
- Heart murmur
- Palpitation
- Poor blood circulation
- Rapid breathing
- Tiredness
Transcatheter Procedures might be used where it is essentially a small invasive procedure that is more commonly done using a catheter (small tube). This includes the delivery of an intravascular device such as a balloon, a coil, or a stent to help expand or close (device closure) existing cardiovascular defects.
Types of transcatheter procedures include:
Cavo-pulmonary shunt (CPS)
Fontan procedure
Ligation of patent ductus arteriosus
Modified blalock taussig shunt (BTS)
Norwood procedure
Pulmonary artery band (PAB)
Rastelli operation
Ross procedure
