A Case Report of Abnormal Branched Right Coronary Artery from Left Sinus of Valsalva
BACKGROUND AND OBJECTIVE: Abnormal origin of coronary arteries, which are responsible for providing the heart with freshly oxygenated blood, can lead to complications affecting daily activity. This variation could be harmless and controlable with the aid of medication but sometimes the bad anatomical situation requires operation. In this severe types, early diagnosis is very important. The aim of thid study was to teach medical students about coronary arteries’ anomalies.
CASE REPORT: Through the thorax dissection sessions of a 57 years old man, we observed that the right coronary artery along with the left main coronary artery is originated from the left sinus of Valsalva. As it passed posteriorly to the aorta, it could have been pressed by the esophagus or the right auricle of the right atrium.
CONCLUSION: This study showed that the right coronary artery arises from left sinus of Valsalva. Together with the significant cardiomegaly and extra pericardial fat, this abnormally originated right coronary artery could be one of the main causes of this person’s health complications while alive
