Retrograde Venography to Navigate an Occluded Subclavian Vein to Achieve CRT Upgrade via His Bundle Pacing
preprint
OA: closed
Abstract
We present a case of pacing-induced cardiomyopathy and an occluded left subclavian vein (SCV). The SCV occlusion was delineated in a retrograde manner from femoral venous access and bypassed through direct puncture of a collateral branch. Cardiac resynchronisation therapy was achieved through His bundle pacing, with subsequent normalisation of LV function.
