1. A method for planning biventricular pacing lead placement for a patient, the method comprising:
- obtaining acquisition data from a medical imaging system;
generating a 3D model of the left ventricle and thoracic wall of the patient from the acquisition data, prior to performing a biventricular pacing procedure on the patient;
identifying one or more left ventricle anatomical landmarks on said 3D model and inserting geometric markers therein corresponding to selected ones of said anatomical landmarks;
registering saved views of said 3D model on an interventional system; and
visualizing one or more of said registered saved views with said interventional system; and
identifying, prior to utilizing said interventional system, at least one suitable region on the left ventricle wall for epicardial lead placement so as to facilitate the biventricular lead placement.

Abstract
A method for planning biventricular pacing lead placement for a patient includes obtaining acquisition data from a medical imaging system and generating a 3D model of the left ventricle and thoracic wall of the patient. One or more left ventricle anatomical landmarks are identified on the 3D model, and saved views of the 3D model are registered on an interventional system. One or more of the registered saved views are visualized with the interventional system, and at least one suitable region on the left ventricle wall is identified for epicardial lead placement.
