1. A method for planning left atrial appendage (LAA) occlusion for a patient, the method comprising:
- planning the LAA occlusion, wherein the planning includes;
obtaining acquisition data from a medical imaging system;
generating a 3D model of the left atrium of the patient;
identifying one or more left atrial anatomical landmarks on said 3D model;
inserting geometric markers within said 3D model, the geometric markers being associated with and inserted at the identified landmarks for subsequent registration;
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.

Abstract
A method for planning left atrial appendage (LAA) occlusion for a patient includes obtaining acquisition data from a medical imaging system, and generating a 3D model of the left atrium of the patient. One or more left atrial 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.
