Atrial tachycardias occurring late after orthotopic heart transplantation are frequently caused by an ongoing atrial tachycardia in the recipient remnant atrium that is associated with intra-atrial muscle band connections between the 2 atrial compartments. The standard approach for most centers that treat these patients is to identify and disconnect these intra-atrial connections. We present a patient where double intra-atrial connections were capable of different degrees of stimulus propagation from the recipient remnant atrium to the donor atrial compartment. After the ablation of both intra-atrial connections, we also ablated the index arrhythmia in the recipient remnant atrium. This case presentation draws attention to the possibility of the presence of multiple intra-atrial connections.
