[Verse 1] Deep in cardiac chambers where the aorta starts to climb Two vessels branch like ancient trees, their origins divine From pockets carved in vessel walls, the sinuses hold tight Valsalva's chambers cradle roots that feed the beating night [Chorus] Left and right coronary streams Racing through myocardial dreams Oxygen highways pump and flow Five branches every surgeon knows Map the arteries before you slice One mistake costs the ultimate price [Verse 2] The left main splits to two pathways, anterior descending While circumflex curves round the back, its oxygen defending Right coronary takes the floor, inferior wall its prize Posterior descending calls when circulation flies [Chorus] Left and right coronary streams Racing through myocardial dreams Oxygen highways pump and flow Five branches every surgeon knows Map the arteries before you slice One mistake costs the ultimate price [Bridge] When truncus shows its twisted face And vessels hide in foreign space Anomalous origins disguised Must be traced before the knife Catheter maps reveal the maze Before the scalpel finds its place [Verse 3] LAD and LCX from left main's fork RCA stands alone, no need to talk PDA from right or left can spring Dominance patterns surgeons sing [Final Chorus] Five coronary lifelines run Left main, LAD, and LCX begun RCA and PDA complete the crown Never let your patients down Identify before you start Save the vessels, save the heart [Outro] In Valsalva's embrace they hide Coronary treasure deep inside
