Carter: L-TGA and Double-Switch Heart Surgery
Carter's pacemaker procedure reveals L-transposition of the great arteries, prompting a much larger congenital heart repair.
In Plain English
Carter's heart chambers and arteries are reversed in a way that can work for years but can later cause rhythm problems and heart failure.
What Happened in the Episode
During the pacing-wire procedure, Park requests contrast because the fluoroscopy does not look right and discovers the reversed anatomy.
Clinical Concept
L-TGA, conduction disease, double-switch surgery, baffle creation, and congenital heart failure risk.
What ER Teams Would Evaluate
Real care would require congenital cardiology, echo/MRI/cath review, rhythm assessment, surgical-risk modeling, and family counseling.
Treatment and Management Overview
Management may include pacemaker, lifelong congenital-heart follow-up, valve and ventricular-function monitoring, and double-switch surgery for selected anatomy.
What TV Gets Right
The episode highlights that L-TGA may be found after rhythm problems and can force a pacemaker-versus-reconstruction decision.
What TV Compresses
It compresses congenital-heart imaging, surgical planning, and ICU recovery.
