Cryoballoon ablation safely isolates the posterior wall and roof line in persistent AF with dextrocardia.
Case Report (n=1)
Cryoballoon ablation for left atrial posterior wall isolation and roof line ablation is feasible and safe even in patients with complex congenital anatomy such as dextrocardia and situs inversus.
Single-case feasibility in dextrocardia; hypothesis-generating and should not yet change practice.
Cryoballoon ablation has been established as an effective method for pulmonary vein isolation and has recently been investigated for its efficacy of substrate modification on the left atrial roof area in patients with persistent atrial fibrillation. We herein report the first successful case of left atrial posterior wall isolation including roof line ablation using cryoballoons in a patient with persistent atrial fibrillation, dextrocardia, and situs inversus. Cryoballoon ablation proved to be a safe and straightforward approach to create lasting lesions along the left atrial roof line and left atrial posterior wall, even under challenging anatomical conditions.

Wada et al. (2024) conducted a case report in Persistent atrial fibrillation, dextrocardia, and situs inversus (n=1). Left atrial posterior wall isolation including roof line ablation using a cryoballoon was evaluated on Successful left atrial posterior wall isolation including roof line ablation. Cryoballoon ablation was a safe and straightforward approach for left atrial posterior wall isolation and roof line ablation in a patient with persistent atrial fibrillation and dextrocardia.
