Key result
Radiofrequency ablation of the muscular part of the sub-pulmonary ventricle at the level of the interatrial septum successfully abolished incessant supraventricular tachycardia in a patient with ccTGA.

Successful ablation of atypical SVT in ccTGA; hypothesis-generating for sub-pulmonary septal mapping in complex CHD.
Case Report (n=1)
This case demonstrates the feasibility of mapping and ablating an atypical septal atrial tachycardia originating from the muscular part of the sub-pulmonary ventricle in a patient with complex congenital heart disease.
Preda et al. (2023) conducted a case report in Incessant supraventricular tachycardia in congenitally corrected transposition of the great arteries (n=1). Radiofrequency ablation of the muscular part of the sub-pulmonary ventricle was evaluated on Abolition of tachycardia. Radiofrequency ablation of the muscular part of the sub-pulmonary ventricle at the level of the interatrial septum successfully abolished incessant supraventricular tachycardia in a patient with ccTGA.
