Right coronary artery

The right coronary artery provides blood to the heart. The right coronary artery splits into the acute marginal arteries and the right posterior coronary artery. Other arteries that are derived from the right and left artery include the left anterior descending artery and the circumflex artery. The heart needs oxygen in the blood to function. The right coronary artery specifically provides blood to the right atrium, heart ventricles, and the cells in the right atrial wall, which are called the sinoatrial node. Injuries to the arteries or a poor functioning artery can cause a heart attack. A disease that affects the artery reduces the amount of oxygen that is delivered to the heart. The anomalous coronary artery is a malformed or abnormal artery. This condition may be congenital. Sometimes problems with the right coronary artery go unnoticed due to a lack of symptoms. Young athletes, specifically those who have heart attacks while participating in strenuous sports, sometimes have an undetected coronary artery anomaly. According to the Children's Hospital of Pittsburg, this condition has been traced to four to fifteen percent of sudden cardiac deaths in children.
