Why the study?
In patients with dextrocardia, transvenous implantable cardioverter-defibrillator placement can be technically challenging and carries higher complication risks than in the general population.
Is right-sided subcutaneous ICD implantation feasible in a patient with situs inversus dextrocardia?
Is right-sided subcutaneous ICD implantation feasible in a patient with situs inversus dextrocardia?
Right-sided subcutaneous ICD implantation is a feasible alternative to transvenous ICD in patients with dextrocardia, avoiding complex transvenous insertion challenges.
May support right-sided S-ICD feasibility in dextrocardia; leaves open generalizability beyond single case reports.
Dextrocardia is a congenital anomaly where the heart is abnormally located in the right hemithorax. In these patients, the implementation of transvenous implantable cardioverter-defibrillator (TV-ICD) can be technically challenging and pose a higher risk of complications than the general population. We present the case of a male patient that was successfully submitted to right-sided implantation of subcutaneous ICD (S-ICD) as an alternative to transvenous ICD (TV-ICD) for primary prevention of sudden cardiac death. This option is not only feasible but may potentially be ideal for these patients, as it circumvents challenges and potential complications of TV-ICD insertion.
