Response to cardiac resynchronization therapy (CRT) may be improved if coronary venous anatomy is fused with information on regional left ventricular (LV) function to guide LV lead placement. We propose a method to register a 3D model of the LV and its corresponding coronary venous tree (reconstructed from biplane X-ray fluoroscopy) for CRT applications. A template coronary venous tree (CVT) centerline, learned from a training set, was utilized to find point-to-point correspondence between the LV surface and the coronary vessels. The method was validated retrospectively on a set of 15 CRT candidates. Two validation experiments were conducted; on a randomly relocated patient specific LV and on a randomly relocated average LV. The absolute distance error between the ground truth and the registered LV was 3.4±1.0 mm for the case of patient specific LV and 4.2±1.0 mm for the case of average LV model. The probability of targeting the correct coronary branch, when using the registered LV compared to the ground truth, was 95.3±2.5 % for the case of patient specific LV and 94.5±3.5 % for the case of average LV model. The results suggest that the method can be used to provide an automatic registration of a 3D LV model to X-ray imaging with potential applications in image fusion to aid image-guided CRT implantation. |
