Method and system of treatment of heart failure using 4D imaging
First Claim
1. A method for treating heart failure in a patient using 4D imaging comprising:
- obtaining cardiac digital data from a medical imaging system utilizing an electrocardiogram (ECG) gated protocol;
generating a series of three-dimensional (3D) images of a cardiac chamber and surrounding structures from the cardiac digital data at select ECG trigger points corresponding with different phases of the cardiac cycle;
registering the 3D images with an interventional system;
acquiring ECG signals from the patient in real-time;
transmitting the ECG signals to the interventional system;
synchronizing the registered 3D images with trigger points on the transmitted ECG signals to generate a 4D image;
visualizing the 4D image upon the interventional system in real-time;
visualizing a pacing/defibrillation lead over the 4D image upon the interventional system;
navigating the pacing/defibrillation lead utilizing the 4D image; and
placing the pacing/defibrillation lead over the cardiac chamber at a select location.

Abstract
A method is provided for treatment of heart failure having the steps of obtaining cardiac digital data from a medical imaging system utilizing an ECG gated protocol; generating a series of 3D images of a cardiac chamber and its surrounding structures, preferably the left ventricle and coronary sinus, from this cardiac digital data at select ECG trigger points that correspond to different phases of the cardiac cycle; registering these 3D images with an interventional system; acquiring ECG signals from the patient in real-time; transmitting these ECG signals to the interventional system; synchronizing the registered 3D images with trigger points on the transmitted ECG signals to generate a 4D image; visualizing this 4D image upon the interventional system in real-time; visualizing a pacing/defibrillation lead over the 4D image upon the interventional system; navigating the pacing/defibrillation lead utilizing the 4D image; and placing the pacing/defibrillation lead over the cardiac chamber at an appropriate site to treat the heart failure.
