AB  - Macro-reentrant atrial and ventricular tachycardias originatefrom additional circuits in which the activation of the cardiac chambersfollows a high-frequency rotating pattern. The macro-reentrant circuitcan be interrupted by targeted radiofrequency energy delivery with alinear lesion transecting the pathway. The choice of the optimal ablationsite is determined by the operator’s experience, thus limiting the proceduresuccess, increasing its duration and also unnecessarily extendingthe ablated tissue area in the case of incorrect ablation target estimation.In this paper, an algorithm for automatic intraoperative detection of thetachycardia reentry path is proposed by modelling the propagation as agraph traverse problem. Moreover, the optimal ablation point where thepath should be transected is computed. Finally, the proposed methodis applied to sparse electroanatomical data to demonstrate its use whenundersampled mapping occurs. Thirteen electroanatomical maps of rightventricle and right and left atrium tachycardias from patients treatedfor congenital heart disease were analysed retrospectively in this study,with prediction accuracy tested against the recorded ablation sites andarrhythmia termination points.
