Right ventricular dysfunction in congenitally corrected transposition of the great arteries and risk of ventricular tachyarrhythmia and sudden death

Dysfunction of the systemic RV in ccTGA increases the risk of sudden death and clinically significant ventricular tachyarrhythmias. Further study is needed to determine if ventricular tachyarrhythmias comprise the primary cause of sudden death in these patients and if ICDs offer any significant mortality benefit.
