Atrial Septal Defect: Understanding a Common Heart Hole

A "Hole in the Heart" Most People Live With Unknowingly

An atrial septal defect (ASD) is an opening in the wall between the heart's two upper chambers. It's one of the most common congenital heart defects — and many people in Nigeria live with a small ASD for decades without knowing it, as small defects often cause no symptoms.

When It Becomes a Problem

Larger defects cause blood to shunt from left to right atrium, overloading the right heart and lungs. Over time this can lead to shortness of breath, atrial fibrillation, pulmonary hypertension, and paradoxical embolism — blood clots crossing to the left side, causing stroke.

Functional Medicine's Role

While ASD may require interventional closure, functional medicine reduces the cardiovascular burden in the meantime: blood pressure and inflammation control reduce right heart strain, CoQ10 and magnesium support cardiac muscle function, and omega-3s and electrolyte balance reduce atrial fibrillation risk.
