Figure 1 - Left sided contrast venography (left panel)
demonstrating lead-related left subclavian venous occlusion (blue
arrow). Retrograde venography (right panel) delineates site of vessel
recanalisation (red arrow).
Figure 2/VIDEO 1 - A collateral branch is identified and wired
using a J-wire (0.035) to guide direct left sub-clavicular percutaneous
puncture, bypassing the occluded left subclavian vein.
Figure 3 - Intracardiac electrograms confirm supra-Hisian AV
block (HV association maintained) and evidence of His injury current
(blue arrows left panel). His-QRSend interval 192ms
(left panel). With His pacing stim-QRSend reduced to
158ms (right panel).
