PANORAMA will collect a large database of device behavior, for instance to monitor long term behavior of device features, technical reliability and longevity, as well as to allow studying device performance in different subgroups of patients. Larger databases are often essential for formulating and testing study hypotheses for prospective (randomized) trials. While it may depend on specific objectives for individual devices, reliable assessment of device performance over longer periods and in broad patient populations typically requires a study population from a few hundred to a few thousand patients. PANORAMA collects acute and chronic patient and device data in a large population during routine usage of the device, without specific study interventions, and always within the approved intended use of the device.
