[Verse 1]
From the aortic root they start their way
Just above the valve leaflets they stay
In pockets called the sinuses of Valsalva
Left and right coronaries gonna solve ya
Heart muscle needs its oxygen supply
These vessels keep the cardiac cells alive
Before you cut, you better know their course
Or infarction becomes your driving force
[Chorus]
Five coronaries dancing through the heart
Left main, LAD, circumflex from the start
Right coronary artery takes its stand
Posterior descending completes the band
Map them out before you make your incision
Anomalous origins need recognition
Five coronaries keep the heart alive
Know their paths so patients will survive
[Verse 2]
Left main splits into two major streams
LAD descends fulfilling cardiac dreams
Circumflex wraps around the lateral wall
Right coronary feeds the inferior hall
Posterior descending from RCA flows
Or from circumflex depending how it goes
Dominance patterns you must understand
Right or left or co-dom take command
[Chorus]
Five coronaries dancing through the heart
Left main, LAD, circumflex from the start
Right coronary artery takes its stand
Posterior descending completes the band
Map them out before you make your incision
Anomalous origins need recognition
Five coronaries keep the heart alive
Know their paths so patients will survive
[Bridge]
When origins are wrong, disaster waits
Surgical injury seals the heart's fate
CT angiography shows the way
Catheterization saves the day
Never assume the normal course
Verify first with imaging force
[Chorus]
Five coronaries dancing through the heart
Left main, LAD, circumflex from the start
Right coronary artery takes its stand
Posterior descending completes the band
Map them out before you make your incision
Anomalous origins need recognition
Five coronaries keep the heart alive
Know their paths so patients will survive
[Outro]
Sinuses of Valsalva hold the key
Coronary perfusion sets hearts free
Five vessels in their perfect design
Map them first and surgery will shine
