[Verse 1]
Ten-month-old with truncus type two
Chamber pressures tell the story true
Threading wires through arterial gates
Oxygen levels seal the patient's fate
Diagnostic probe reveals the stenosis tight
Conduit narrowed, blocking precious flight
[Chorus]
Cath lab magic, measure and repair
Pressures, sats, and resistance we declare
PVR calculation holds the key
Operability's what we need to see
Direct access to the beating core
Intervention opens up the door
[Verse 2]
Pulmonary vascular numbers climb
Resistance ratios drawn in real time
Wedge pressure gradients paint the scene
Stenotic conduit caught between
Balloon angioplasty stretches wide
Hemodynamics shift from side to side
[Chorus]
Cath lab magic, measure and repair
Pressures, sats, and resistance we declare
PVR calculation holds the key
Operability's what we need to see
Direct access to the beating core
Intervention opens up the door
[Bridge]
Fluoroscopy guides the dancing catheter
Contrast medium flows like liquid theater
Pre and post gradients tell the tale
Success measured when pressures sail
From diagnostic glimpse to fixing flaw
One procedure follows nature's law
[Verse 3]
Oxygen saturation maps the shunt
Chamber sampling shows the cardiac hunt
Right heart pressures elevated high
Left ventricle working overtime
Conduit dilation breaks the chain
Restoring flow through pediatric vein
[Chorus]
Cath lab magic, measure and repair
Pressures, sats, and resistance we declare
PVR calculation holds the key
Operability's what we need to see
Direct access to the beating core
Intervention opens up the door
[Outro]
From stenosis tight to conduit free
Cardiac catheterization's victory
