Implication
Anterior conduction anatomy in corrected transposition warrants surgical caution; leaves open whether mapping improves outcomes beyond these cases.
Structured PICO
P
Population
2 patients with corrected transposition of the great arteries (l-TGA) with situs solitus, dextrocardia or dextroversion and membranous ventricular septal defect (VSD).
I
Intervention
Electrophysiologic identification of the specialized conduction system during open-heart surgery.
O
Outcome
Location of the specialized conduction system electrograms.surrogate
In patients with corrected transposition of the great arteries, the specialized conduction system is located anterior to the membranous VSD, which is critical for avoiding heart block during surgical repair.
