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.

A method for quantifying cardiac desynchrony of the right and left ventricles includes obtaining cardiac acquisition data from a medical imaging system, and determining a movement profile from the cardiac acquisition data. The movement profile is directed toward identifying at least one of a time-based contraction parameter for a region of the left ventricle (LV), and a displacement-based contraction parameter for a region of the LV. The determined movement profile is visually displayed by generating a 3D model therefrom.

A method for acquiring a cardiac image from a patient having a paced heart rhythm, an abnormal EKG, or an irregular heartbeat, is disclosed. A gated electrocardiogram signal having local maxima and minima values and trigger points is received. For a period of time, the time between each trigger point and the associated local maxima or minima is determined. In response to the trigger point occurring at the associated local maxima or minima, a zero time differential for a corrected trigger for gating is calculated, and in response to the trigger point not occurring at the associated local maxima or minima, a time differential for the corrected trigger for gating based on the time difference between the trigger point and the associated local maxima or minima is calculated.

In order to reduce bias associated with conventional ECG analysis, the present invention provides a method and apparatus to improve diagnosis of acute cardiac syndromes (ACS), such as acute myocardial infarction and acute cardiac ischemia (unstable angina), in specified groups of patients using ECG signals and automatic detection analysis. Specific criteria are developed and utilized based on a prespecified group selection for the particular patient. After identifying group membership for the particular patient, ECG data are acquired from a patient experiencing ACS symptoms. Known criteria typically used for assessing ACS are then modified for the particular group membership. Such criteria significantly reduce the bias found in a baseline group for which the known criteria were established. The invention is particularly useful in identifying an ACS, and the type of ACS, in females under the age of 60 where it has been found that the current critical ST threshold is too high to consistently identify an ACS in this subgroup.
