Two-dimensional (A) and color Doppler (B) echocardiographic images. A: Right atrium and right ventricle were globally enlarged. Insertion of septal leaflet (white arrow) was markedly displaced toward the apex. B: Moderate tricuspid regurgitation (central jet area 7.84 cm2). aRV = atrialized right ventricle; fRV = functional right ventricle; LA = left atrium; LV = left ventricle; RA = right atrium; RV = right ventricle.

On color Doppler echocardiography, single tricuspid regurgitation was noted, which was considered to be moderate based on the color jet area method (Figure 1).
Anterior (left) and posterior (right) views of the 3-dimensional mapping system. White dots indicate endocardial ablation sites in the left atrium. Blue dots indicate disconnection sites of pulmonary vein potential. Orange dots indicate epicardial ablation sites inside the coronary sinus. Green dots indicate ablation sites on the cavotricuspid isthmus.

Therefore, linear ablations of the roof, mitral isthmus, and cavotricuspid isthmus (CTI) were performed (Figure 2).
