Representative Cases
Three representative cases of LV-LP guided by Inner-Cath alone are shown
in Figure 2. LV leads were successfully placed in different CS
tributaries (posterolateral, lateral, anterolateral veins). Case 1 was a
74-year-old male with dilated cardiomyopathy (DCM). It was possible to
advance an Inner-Cath deeply inside a thick posterolateral vein, that
strengthened the backup force for LV lead delivery into the target vein.
Case 2 was a 75-year-old male with ischemic cardiomyopathy (ICM).
Although an Inner-Cath was only advanced to a proximal bend of the
lateral vein, the LV lead was smoothly delivered to an adequate
position. Case 3 was a 43-year-old male with ICM. The targeted
anterolateral vein diverged from the CS trunk with a curve of greater
than 90 degrees. Despite the Inner-Cath not being expected to provide
enough backup force for LV lead delivery, the LV lead was successfully
inserted into the targeted anterolateral vein without effort.
