Abstract
A method for performing a medical procedure, includes, coupling a probe to tissue in an organ of a patient. Ablation energy is applied to the tissue using the probe. A model of an evolution of steam pressure in the tissue, caused by the ablation energy, as a function of time is estimated. Based on the model, an occurrence time of a steam pop event caused by the steam pressure is predicted, and the predicted occurrence time of the steam pop event is indicated to an operator.
