Cardiac Resynchronization Therapy Delivery Guided Non-Invasive Electrical and Venous Anatomy Assessment

"The following information and data will be obtained from the routine clinical work up of the patients: Patient demographics, cardiovascular medical history, and clinical examination; 12-lead ECG; Standard echocardiography; Computed tomography angiography for visualization of atria, ventricle, and coronary sinus.~Imaging data will be transferred to the cloud-based web-platform using a dedicated software provided by study sponsor. Data processing includes evaluating the quality of the data and calculation of various anatomical and electrical parameters, and identification of the target zone as a point in the target vein closest to the latest activation zone.~LV-lead location is based on the information provided by the dedicated software followed by visual X-ray based verification of anatomically suitable/most desirable position.~The patient will undergo CRT device implantation according to local protocols."
