Undetected Artery Anomalies Pose Risk to Children's Hearts During Intense Activity
The right coronary artery, a crucial blood supplier to the heart, can sometimes have anomalies that go undetected, posing a risk, particularly in children during intense physical activity. These anomalies can lead to sudden cardiac arrest due to compromised blood flow and ischemia.
The right coronary artery, one of several major vessels serving the heart, splits into the acute marginal arteries and the right posterior coronary artery. It supplies blood to vital parts like the right atrium, heart ventricles, and the sinoatrial node in the right atrial wall. However, it can sometimes originate from an abnormal location, leading to coronary artery anomalies. These anomalies can cause obstruction or spasm, leading to ischemia and potentially triggering sudden cardiac arrest during exertion.
Coronary artery anomalies are typically present at birth and can go unnoticed due to a lack of symptoms. They have been linked to sudden cardiac deaths in children, with an incidence ranging from four to fifteen percent. Other arteries derived from the right and left coronary arteries include the left anterior descending artery and the circumflex artery. Diseases like coronary artery disease can also reduce the amount of oxygen delivered to the heart by blocking or impeding the artery, potentially leading to a heart attack.
Understanding the potential risks of undetected coronary artery anomalies is crucial, especially in children involved in intense sports activities. Regular cardiac screenings can help detect these anomalies, ensuring timely intervention and prevention of sudden cardiac arrest.
