This case report demonstrates that twin atrioventricular nodes can occur in congenitally corrected transposition with a straddling tricuspid valve, and can be successfully treated with ablation.
This report describes a case of reentrant supraventricular tachycardia relating to "twin" atrioventricular nodes in a 6-year-old female patient with congenitally corrected transposition of the great arteries associated with straddling tricuspid valve. Straddling and overriding of the tricuspid valve literally or by definition indicate malalignment of the inlet part of the ventricular septum and atrial septum by an abnormally large ventriculoatrial septal angle. Therefore, anterior atrioventricular conduction tissues are expected in this setting; however, the present report describes an exception to the rule that combination of straddling tricuspid valve is unlikely to be associated with twin atrioventricular nodes/sling. The patient underwent successful ablation of one atrioventricular node, eliminating the tachycardia, and subsequently Fontan-type palliation.

Takahashi et al. (2011) conducted a case report in Congenitally corrected transposition of the great arteries associated with straddling tricuspid valve and reentrant supraventricular tachycardia (n=1). Ablation of one atrioventricular node was evaluated on Elimination of tachycardia. Ablation of one atrioventricular node successfully eliminated reentrant supraventricular tachycardia in a 6-year-old female with congenitally corrected transposition and a straddling tricuspid valve.
