[Verse 1] Before the scalpel finds the old scar's seam, trace the artery's map, follow the stream — anomalous LAD riding off the right side, crossing the RVOT with nowhere to hide. Single coronary feeding the whole house, one trunk, two branches, no room to carouse. Re-entry's a blind reach through sticky terrain, cut the wrong plane and you've sealed off the vein. [Chorus] Cut it, pinched it, squeezed it shut — left main and LAD, mind the gut of the conduit pressing where it lays. ST climbs, the wall won't move, rhythm strays — that's compression singing through the chest, reposition, bypass, or lay the old graft to rest. [Verse 2] Now the new tube's seated, stiffer than before, riding posterior, pinned to the floor where the left main travels behind the tract — it's the valve-deployment squeeze, same mechanical fact. A rigid conduit's a boot on a hose, no flow gets through wherever it goes. Size matters less than the stiffness it's packed — a floppy homograft won't choke off the tract. [Chorus] Cut it, pinched it, squeezed it shut — left main and LAD, mind the gut of the conduit pressing where it lays. ST climbs, the wall won't move, rhythm strays — that's compression singing through the chest, reposition, bypass, or lay the old graft to rest. [Verse 3] On bypass the monitor starts the tale — ST segments rising, the TEE turns pale, a patch of wall that stopped keeping the beat, regional motion dead on its feet. PVCs firing, V-tach at the door, and the heart just won't wean off the pump anymore. Four signals stacked is a chorus of alarm — read the strip, read the echo, name the harm. [Bridge] Shorten the conduit, give the vessel room, reposition the tube away from the tomb of the left main's track, or bypass the gap with a graft of your own, reroute the map. Reimplant the coronary if it's torn at the base, buy that artery back its rightful space. Compression's a clock, myocardium's the cost — read the pressure line before the muscle's lost. [Verse 4] Before you ever scrub, let the CT scan speak, trace the vessel's bend, find its hidden technique. Balloon the catheter first, test the squeeze you'll find, inflate in the cath lab, read the artery's mind. Careful dissection peels the plane like a page, slow hands reading anatomy, not hands in a rage. Scan it, test it, see it — the mnemonic stays true: cut smart, build smart, give the vessel its due. [Chorus] Cut it, pinched it, squeezed it shut — left main and LAD, mind the gut of the conduit pressing where it lays. ST climbs, the wall won't move, rhythm strays — that's compression singing through the chest, reposition, bypass, or lay the old graft to rest. [Outro] Left main, LAD, the tube pressing tight — reposition, bypass, reimplant, get the flow right. Scan before, balloon before, dissect with care — coronary compromise is always there.
