Figure 1
A) Multipolar catheter (#) positioned around the tricuspid valve (TV) showed a counter-clockwise activation of the right atrium (RA) (cycle length 268 ms) with 2:1 atrioventricular conduction. The ablation catheter (*) positioned at the RA free wall recorded ...

Figure 2
Activation maps of native right atrium (N-RA) and donor right atrium (D-RA) showed earliest activation originating from the upper part of lateral free wall and counter-clockwise activation around the tricuspid valve (TV) respectively. As expected, voltages ...
