THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The right coronary artery (RCA) traces along the right coronary sulcus and provides blood flow to the anterior and diaphragmatic surfaces of the right atrium and ventricle; as well as the posterior two-thirds of the interventricular septum.

Detailed explanation-2: -The RCA gives two major branches; the conus (arteriosus) artery and the sinoatrial artery. The conus artery is the first provided branch by the RCA; it originates from the ostium of the RCA or separately from the right coronary sinus and has a superior and anterior course.

Detailed explanation-3: -LAD: left anterior descending coronary artery; LCx: left circumflex coronary artery; RCA: right coronary artery; SCA: single coronary artery. This case demonstrates a rare congenital coronary artery anomaly found incidentally with a presentation of atypical angina and three-vessel coronary artery disease (CAD).

Detailed explanation-4: -Root Cause Analysis (RCA) is a method or methodology that is used to investigate an incident in order to assist in the identification of health system failures that may not be immediately apparent at initial review.
