May warrant closer SCD monitoring in ccTGA; leaves open optimal risk stratification strategies.
Observational (n=39)
No
Adults with ccTGA face a notable risk of sudden cardiac death even when asymptomatic or mildly symptomatic with preserved or mildly impaired systemic ventricular function, highlighting the need for improved risk stratification.
McCombe et al. (2016) conducted an observational in Congenitally corrected transposition of the great arteries (ccTGA) (n=39). In adults with congenitally corrected transposition of the great arteries, sudden cardiac death occurred at a rate of 1 death per 109 patient-years despite reasonable ventricular function.
