Primary Percutaneous Coronary Intervention Using BaLloon-Assisted Sliding and Tracking (BLAST) of Diagnostic Catheter to Negotiate Double Hairpin Loop of Radial Artery

Abstract

During transradial intervention, sharp edge of the guide catheter tip may act like a “razor-blade” and can prevent the catheter navigation especially in situation like double hair pin loop. Here, we report primary percutaneous coronary intervention (PCI) through diagnostic catheter using an innovative technique, balloon-assisted sliding and tracking (BLAST), to overcome this double hairpin loop, thus saving time and contrast volume.

Zastosowanie techniki BaLloon Assisted Sliding and Tracking of GuideLiner (BLAST-G) do skutecznego umieszczenia stentu w zwapniałej zmianie o krętym przebiegu — opis przypadku

“…Therefore, it should be properly vented in order to diminish the risk of air embolism and the movement should be gentle. We have experienced success with BLAST technique to overcome 360° loop and bend to overcome complex radial artery tortuosity in transradial catheterisation [8], Therefore, BLAST-G technique is simple and effective approach to facilitate the advancement of the GuideLiner catheter through tortuous, heavily calcifield lesion and may be considered as a complementary technique to facilitate GuideLiner assisted PCI, in situations when anchor ballooning is not helpful or unfeasible, and BAT is unsuccessful.…”

Regarding “Safely Traversing Venous Sinus Stenosis: The ‘Cobra’ Technique”

“…In regard to its utility, it should be noted that this technique is routinely used by our interventional cardiology colleagues and is known as “balloon-assisted tracking.” 6–9 It is also described in the peripheral endovascular literature as the “battering-balloon” technique (notably, this is how we refer to it at our institution, as an homage to battering rams used in medieval times). 10…”

“…The authors note they have used this technique in 30 patients undergoing venous sinus stenting without complications.In regard to its utility, it should be noted that this technique is routinely used by our interventional cardiology colleagues and is known as "balloon-assisted tracking." [6][7][8][9] It is also described in the peripheral endovascular literature as the "battering-balloon" technique (notably, this is how we refer to it at our institution, as an homage to battering rams used in medieval times). 10 We have had similar results and find that this technique is both safe and effective, allowing us to gain access beyond areas of stenosis without causing hemorrhagic complications or dissections (Video).…”
