Which congenital cardiac defect does not cause heart failure?

Option 3 : TGA

Concept:

• Heart failure occurs when the heart muscle doesn't pump blood in an efficient way and fails to supply blood.
• Types of heart failure:-
  • Left-sided heart failure
  • Right-sided heart failure
  • Diastolic heart failure
  • Systolic heart failure
• Transposition of the Great Arteries or d-TGA is a cardiac birth defect in which the two main arteries carrying blood out of the heart – the main pulmonary artery and the aorta are switched in position, or “transposed.” Because a baby with this defect may need surgery or other procedures soon after birth.
• It has lower chances to develop heart defect as compare to the other congenital anomalies.

•  In case of patent ductus arteriosus it can lead to Eisenmenger syndrome, an irreversible type of pulmonary hypertension and then leads to Heart failure. A patent ductus arteriosus can later on causes the heart to enlarge and weaken, leading to heart failure, a chronic condition in which the pumping action of heart is diminished.
• Atrial septal defects usually closes during infancy. Larger atrial septal defects can cause serious complications, like Right-sided heart failure.
• Ventricular Septal Defect  is a birth defect of the heart in which there is a hole in the wall (septum) that separates the two lower ventricles of the heart. If there is medium or large VSD , the heart works harder and the lungs have too much blood pumped to them. Without treatment, heart failure can develop.
