Key result
Ablation from the pulmonic valve was utilized to treat atrial tachycardia originating from the atrial septum in a patient with {I, D, D}-type ccTGA.
Why the study?
While atrial tachycardia originating from para-Hisian areas in {S, L, L}-type ccTGA has been reported, limited data exist for {I, D, D}-type ccTGA.
Demonstrates a novel ablation approach from the pulmonic valve for atrial tachycardia in a patient with rare {I, D, D}-type congenitally corrected transposition of the great arteries.
May offer alternative access for septal AT ablation in rare ccTGA; extends case reports but leaves generalizability open.
Atrial tachycardia (AT) originating from para-Hisian areas in patients with {S, L, L}-type congenitally corrected transposition of the great arteries (ccTGA) has been previously reported. However, limited data are available for the {I, D, D}-type ccTGA. We present a unique case of a patient with {I, D, D}-type ccTGA and AT originating from the atrial septum and ablation from the pulmonic valve.
