Cardiac resynchronization therapy by pacing the right ventricular dorsal site of inflow and anterior outflow for congenitally corrected transposition of the great arteries: a case report.

ABSTRACT:

Background

Evidence regarding cardiac resynchronization therapy (CRT) for congenitally corrected transposition of the great arteries (ccTGA) is insufficient. The timing to perform CRT and optimal pacing sites have not been systematically studied. We performed CRT for ccTGA with a complete atrioventricular block (CAVB) by pacing the dorsal site of right ventricular inflow (dRVI) and anterior RV outflow tract (aRVOT).

Case summary

We examined a man aged 19 with ccTGA (S.L.L) and Ebstein anomaly, who developed CAVB at 19. We decided to implant CRT rather than a conventional pacemaker for preventing right ventricular (RV) dysfunction. At first, we implanted transvenous pacing leads on the right atrium and dRVI via the coronary sinus. During dRVI pacing, the most delayed contract
