The SA nodal artery (SANA) is an atrial branch usually in 65% arising from right coronary artery and in 35% from left Circumflex artery (LCx). In the previous studies, the variation such as ‘S’ shaped course of SANA was reported. Study included 55 human hearts obtained from Department of Anatomy, SSMC. Embalmed human hearts were dissected and analysed to study the incidence of ‘S’ Shaped SA nodal artery. In the present study,S’ shaped SA nodal artery was observed in 2 specimens one from the left circumflex artery (LCx) and other from Right Coronary artery (RCA).There is a high chance of vulnerable injury to SA nodal artery especially “S” Shaped SANA at the time of various surgical procedures like coronary stent insertion or balloon insertion. It is advisable to have MDCT to diagnosis and to establish a good preoperative plan for interventional cardiac procedures.
