[Verse 1]
When neonates arrive with murmurs strange and blue
The echo probe reveals what stethoscopes can't do
A single vessel towers where two should stand apart
Overriding septal holes within the beating heart
[Chorus]
Truncus echo tells the tale
VSD beneath the vessel's trail
Count the leaflets, check the flow
PA branches high and low
Nakata index, Z-scores tracked
Valve gradients, regurg mapped
Serial measurements we chase
Through this cardiac diagnostic space
[Verse 2]
Truncal valve morphology demands our keen attention
Two or three or four leaflets in anatomic tension
Regurgitation whispers through incompetent doors
While gradient pressures build like waves upon the shores
[Chorus]
Truncus echo tells the tale
VSD beneath the vessel's trail
Count the leaflets, check the flow
PA branches high and low
Nakata index, Z-scores tracked
Valve gradients, regurg mapped
Serial measurements we chase
Through this cardiac diagnostic space
[Bridge]
Map the pulmonary arteries, their origins and size
ASD and PFO hiding in disguise
Aortic arch sidedness, interruption's threat
Ventricular function - ejection fractions met
[Verse 3]
Associated anomalies lurk in cardiac shadow
Patent foramen ovale through atrial meadow
Right or left the aortic arch may choose to bend
While ventricular performance tells us how this ends
[Chorus]
Truncus echo tells the tale
VSD beneath the vessel's trail
Count the leaflets, check the flow
PA branches high and low
Nakata index, Z-scores tracked
Valve gradients, regurg mapped
Serial measurements we chase
Through this cardiac diagnostic space
[Outro]
Primary diagnostic gold standard in our hands
Echocardiography reveals what surgery demands
