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.
