Signs of Congenital Heart Disease in Children — What Parents Should Know

Congenital heart defects affect thousands of children in Pakistan every year. Many go undiagnosed until serious damage is done. Here are the warning signs every parent should know.

Congenital heart disease (CHD) is the most common birth defect worldwide, and Pakistan has one of the highest rates in Asia. Many children live with undiagnosed heart conditions for years — not because the diagnosis is difficult, but because their families cannot access or afford specialist care.

What Is a Congenital Heart Defect?

A congenital heart defect is a structural problem with the heart present from birth. The most common type is a Ventricular Septal Defect (VSD) — a hole in the wall between the heart's two lower chambers. Small holes sometimes close on their own. Larger ones require surgical repair.

Warning Signs in Infants and Young Children

  • Blue or purple tint to the lips, tongue, or fingernails (cyanosis)
  • Rapid breathing or difficulty breathing, especially during feeding
  • Excessive sweating during feeding or activity
  • Poor weight gain or stunted growth
  • Extreme tiredness or lethargy
  • Swelling in the legs, abdomen, or around the eyes
  • Frequent respiratory infections

What Can Parents Do?

If your child shows any of these signs, see a doctor immediately. Do not wait for the next routine checkup. A simple echocardiogram (heart ultrasound) can diagnose most congenital heart defects within minutes. In Pakistan, this is available at most large hospitals.

Zara's Story

Zara N., 7 years old, was born with a ventricular septal defect. She has struggled with breathlessness and fatigue her entire short life. Surgery at NICVD has a 94% success rate and would give her a completely normal life. Without it, her doctors give her less than 18 months. Her parents are daily-wage workers who cannot afford the $2,300 cost.
