Abstract

We encountered a case of blow-out type coronary perforation at the calcified stenosis of left anterior descending artery. First, we started immediate balloon tamponade through the initial guiding catheter (GC) with a GuideLiner® catheter. Next, we introduced a second GC with a GuideLiner® catheter and successfully deployed a covered stent. Two sets of the GC with GuideLiner® catheter facilitated us to simultaneously perform temporary hemostasis with balloon tamponade and rapid delivery of a covered stent. To alternately manipulate the GuideLiner® catheters, back and forth with seesaw-like motion enabled us to minimize the interruption of balloon tamponade.

Abstract

In practical settings of percutaneous coronary intervention (PCI), we sometimes encounter difficulty in introducing a guidewire (GW) to the markedly angulated side branch (SB), and the reverse wire technique is considered as a last resort to overcome such a situation. We analyzed 12 cases that underwent PCI with dual-lumen microcatheter-facilitated reverse wire technique between January 2013 and July 2016. We retrospectively investigated the lesion's characteristics and the details of the PCI procedures, and discussed tips about the use of this technique. The SB that exhibits both a smaller take-off angle and a larger carina angle is considered to be the most suitable candidate for this technique. The first step of this technique involves the delivery of the reverse wire system to the target bifurcation. However, most cases exhibit significant stenosis proximal to the bifurcation, which often hampers the delivery of the reverse wire system. Because the sharply curved reverse wire system is easier to pass the stenosis as compared to the roundly curved system, we recommend a sharp curve should be adopted for this technique. On the other hand, it is sure that device delivery is much easier on the GW with a round curve as compared to that with a sharp curve. Therefore, it is important to modify the details of this procedure on a case-by-case basis according to the lesion's characteristics.
