Complications of Swartz sheath support approach for DGCV-AIV
VAs
Of note, a relative higher rate of cardiac vein dissection and rupture
was observed in SS approach. We speculated that while SS approach
application provided a better backup for catheter manipulation, it also
increased the contract force of catheter tip to the coronary vein,
contributing a higher incidence of coronary vein damage.
In our study, coronary injury was found in both groups. Though the safe
distance from the catheter tip to the adjacent coronary artery has been
demonstrated by coronary angiography, coronary injury is still a
potential complication, which could not be neglected.
