[Verse 1]
When the heart's structure isn't right
Truncus arteriosus in our sight
One vessel where there should be two
Cardiac cath will guide us through
Insert the wire, thread with care
To chambers deep, we venture there
[Chorus]
Pressure and saturation, measure what we find
PVR calculation, operability defined
Diagnostic and interventional, two paths in one line
Cardiac catheterization, making hearts align
[Verse 2]
Ten months old with conduit tight
Stenosis blocking proper flight
The pressures tell us what's inside
While oxygen levels are our guide
From right to left, we map each zone
Making abnormal hearts our own
[Chorus]
Pressure and saturation, measure what we find
PVR calculation, operability defined
Diagnostic and interventional, two paths in one line
Cardiac catheterization, making hearts align
[Bridge]
When resistance climbs too high
Surgery we can't apply
But when the numbers look just right
We can restore the flow of life
Balloon or stent, we choose our tool
Interventional cardiology's jewel
[Verse 3]
Direct measurement beats the guess
Chamber pressures under stress
Calculate the vascular resistance
Determines surgical assistance
From diagnostic to repair
One procedure, comprehensive care
[Chorus]
Pressure and saturation, measure what we find
PVR calculation, operability defined
Diagnostic and interventional, two paths in one line
Cardiac catheterization, making hearts align
[Outro]
Wire in hand, we navigate
The chambers that communicate
One test to rule them all we find
Cardiac cath, peace of mind
