[Verse 1]
When the conduit starts to narrow down
The right ventricle must work much harder now
Normal pressure twenty to thirty max
But stenosis changes all the facts
Blood must flow from RV to PA
Through a passage getting tight each day
The heart pumps harder, pressure climbs
Racing against the test of time
[Chorus]
Pressure gradient tells the tale
When the conduit starts to fail
Rising numbers, warning signs
Suprasystemic pressure climbs
Gradient gap between RV and PA
Shows us how the stenosis plays
Watch the numbers, know the trend
Before the right heart meets its end
[Verse 2]
At two months old, thirty peak gradient
Little baby's heart still competent
Three months later, thirty-two's the score
Ten millimeter lumen, nothing more
But seven months brings alarming news
Sixty-seven peak, the pressure blues
Nine point eight millimeters left
Of passage through this narrowed cleft
[Chorus]
Pressure gradient tells the tale
When the conduit starts to fail
Rising numbers, warning signs
Suprasystemic pressure climbs
Gradient gap between RV and PA
Shows us how the stenosis plays
Watch the numbers, know the trend
Before the right heart meets its end
[Bridge]
Mean gradient thirty-seven high
Leaflet motion restricted, why?
RV pressure beats the left
Suprasystemic, hope bereft
Hypertrophy starts to grow
When the pressure's got nowhere to go
Intervention saves the day
Brings that gradient back our way
[Verse 3]
Post procedure, forty-eight peak
Forty-six RV, no longer bleak
The conduit's breathing room restored
Though regurgitation now's on board
Monitor closely, watch for signs
Rising gradients, pressure lines
Early action saves the heart
When we catch stenosis from the start
[Outro]
Pressure gradient tells the story
Of conduit stenosis, warning glory
Rising numbers never lie
Suprasystemic pressure's cry
Watch the gap and intervene
Keep that conduit running clean
