Novel Method

Adequate guide support is crucial for percutaneous coronary interventions complicated by unfavorable coronary artery anatomy, pronounced calcification, or the presence of chronic total occlusion. A clinical case presents a novel technique for guide support during stenting chronic coronary occlusion via transradial approach originally proposed in the TransRadial Ultra Support Technique trial.

Abstract Background Longitudinal stent deformation (LSD) is an uncommon but recognized mechanical complication of coronary stent implantation, usually occurring at the proximal stent edge due to compression by guide catheter or catheter extensions. Retrograde techniques for chronic total occlusion (CTO) percutaneous coronary intervention expose the distal stent edge to potential interaction with retrograde equipment under a tensioned system. Case summary We describe a case of distal stent edge LSD, occurring during a retrograde approach to a right coronary artery CTO via septal collateral channels. While removing the externalized wire, interaction with the retrograde microcatheter caused compression of the distal end of the newly implanted stents. Discussion This unusual complication highlights the reduced longitudinal strength of newer generation stent platforms and the risks of interaction between retrograde equipment and stents on an externalized wire.

Advancement of a sheath or guide catheter into a small, diseased or angled branch vessel such as the superior mesenteric artery or renal artery can be difficult. Similarly, there are times when placement of a sheath up and over a sharply angulated aortic bifurcation can present a challenge. Obtaining a sheath position at or beyond a stenotic or occlusive lesion may be critical for delivering a stent, particularly with the inherent risk of dislodgment associated with balloon-expandable stents. The use of balloons as anchors has been described most commonly in the coronary vasculature, but it can have an important role in peripheral and visceral applications. This chapter discusses the utility of balloons as an anchor to advance a sheath or stent to a target location.
