A method (94) for aligning a cardiac model can include receiving (95) an initial position signal from three position sensors (17, 39, 40) disposed along a distal end of a coronary sinus catheter (13) positioned in a coronary sinus (41) of a heart (10). The method (94) can include receiving (96) a subsequent position signal from the three position sensors (17, 39, 40). The method (94) can include determining (97) a positional change vector based on a change in position between an initial position associated with the initial position signal and a subsequent position associated with the subsequent position signal. The method (94) can include shifting (98) a point of interest associated with a cardiac model, using the positional change vector. The method (94) can include dynamically aligning (100) the cardiac model based on an updated position of the three position sensors (17, 39, 40).
