Figure 3. Late reconnection of the right inferior pulmonary veins in a 56 years old patient with PAF following 32 months the index PVI. Single ablation attempt at the level of earliest PV potentials on Lasso,[4-5] bipoles (arrow) resulted immediate isolation of the vein. All of the other pulmonary veins were isolated. Surface ECG leads I, II, V1 and V6, together with intracardiac recordings from the Lasso catheter (Lasso) placed in the right inferior pulmonary vein, and from the proximal to distal coronary sinus bipoles (CS). Tracing is originating from the database of Szeged University.
