Subcutaneous implantable cardioverter-defi brillator(S-ICD)therapy has become a viable alternative to conventional transvenous ICD implantation.Patients with congenitally corrected transposition of the great arteries(ccTGA)have a high risk of sudden cardiac death due to malignant arrhythmia.The interaction between the S-ICD system and the transvenous pacemaker system is not fully understood.We report a case of S-ICD implantation in a patient with ccTGA and a DDD pacemaker.The patient was a 30-year-old man with a previously placed pacemaker with diagnoses of congenital heart disease,ccTGA(SLL),left atrioventricular valve insuffi ciency,and third-degree atrioventricular block.He presented with an out-of-hospital cardiac arrest,and an S-ICD was implanted to prevent sudden cardiac death.Defi brillation checks were performed successfully.We tested the compatibility of the DDD pacemaker with the S-ICD and found that there was no interference between them.In conclusion,an S-ICD system is a reasonable and safe option in patients with ccTGA.
