We report a pediatric patient with a congenitally corrected transposition of the great arteries (ccTGA)(SLL) in which permanent para-Hisian pacing (PPHP) could improve dyssynchrony-associated systemic ventricular (SV) dysfunction resulting from permanent morphologic left ventricular pacing for complete atrioventricular block. Since, in patients with ccTGA(SLL), an elongated His-bundle runs medially toward the upper septum to the site of the fibrous continuity between the right-sided mitral valve and pulmonary artery, the His-bundle may easily be captured by a pacing lead, unlike in normal hearts. Thus, PPHP may be an effective therapeutic strategy for the treatment of dyssynchrony-associated SV dysfunction associated with ccTGA (SLL).
