Figure 1. LV lead placement guided by Inner-Cath alone
A: A 5Fr deflectable EP catheter was advanced to the CS to guide the
Inner-Cath. B: Once the Inner-Cath was inserted in the CS trunk, CS
venography was performed. In this and other figures, the white arrow
indicates where the Inner-Cath ends. C: Finally, an LV lead was advanced
to the target vein along an 0.014-inch guidewire. D: Example of
occlusive CS venography performed with a balloon catheter placed via an
Inner-Cath followed by LV lead placement.
