Excerpt
The Impella 5.0—a circulatory assist pump catheter for the management of patients with cardiogenic shock—is introduced via the femoral, axillary, or subclavian arteries [
1]. However, in introducing this device, not only should the diameter of the access be considered but also the device’s limit of flexion within the aorta, especially in patients with small stature. In Japan, the medical device package insert states that an aortic arch diameter of 69 mm or more is required for introducing this pump via a vascular approach through the femoral artery, considering the flexion limits of the Impella 5.0 [
2]. However, the basis for this cut-off value, as well as the ranges of patient height and other characteristics for which this cut-off is applicable, remains unclear. As marketed in other countries, there is no such restriction on aortic arch diameter for use of this device. …
