Telescoping catheter technique in percutaneous coronary intervention. Case resolution

Abstract

CASE RESOLUTION A scheduled procedure was decided. An 8-Fr 45 cm long Flexor Shuttle-SL introducer guiding sheath (Cook, United States) was inserted via femoral access again. An 8-Fr AL2 guide catheter was inserted into the ostium of the aortocoronary graft with a valve with a body shorter than usual, the FLO40XR hemostasis valve (Merit, United States). Afterwards, a 120 cm straight tip 5-Fr Heartrail ST01 guide catheter was inserted (Terumo, Japan) that was connected to a different FLO40XR valve. The SION blue Extra Support guidewire (Asahi Intecc, Japan) was advanced towards the left circumflex artery, and mounted over it, a 5-Fr GuideLiner guide extension catheter (Teleflex, United States) was advanced. The goal of this telescoping catheter system was to increase support to be able to move the stent forward (figure 1 and figure 2). Figure 1. Arrangement of the catheters with their special valves to allow a longer usable length. The valves with the shortest bodies allow longer effective catheter lengths to reach the target lesion.
