![]() Of course, it can also be used for tortuous arteries with high degree bends. SIGN IN for Pricing and Availability Representative image. We think that the guiding extension for rotablation burr advancement is a valuable option for some distal locations of a calcified lesion treated with coronary angioplasty. GuideLiner catheters are intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/or peripheral vasculature, and to facilitate placement of interventional devices. flat fee (based on the size of the enterprise and the volume of work). On the other hand, the risk is comparable to the regular situation with the guiding catheter. GuideLiner provides services in the fields of corporate management and corporate. We advise using Dynaglide protocol to advance and remove the burr with careful manipulation of the burr at the tip of the guiding extension during removal just to prevent damage of the tip. Based on our experience, we can recommend checking the matching outside the patient.Ī very important issue is the protocol of system manipulation. Of course, one should remember that the internal diameter of the guiding extension has to be matched with the outer diameter of the burr. In the present case, we used the Guideliner to overcome the mentioned issues. Additionally, the artery’s bending provides a risk of burr stack. The well-known limitation of the high speed rotational atherectomy system is the quite short range of burr movement. (d) After anchoring it with a 1.5 mm balloon, the GuideLiner catheter was selectively introduced into the left coronary artery. GuideLiner catheters are intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/or peripheral vasculature. After that, coronary stenting was performed without any obstacles. PCI cases have been previously described using guides as small as 4 F 5 and as big as 8 F. (c) A 1.5 mm semicompliance balloon in the lead, along with a mother-child system, including a 6-Fr AL-1 guide catheter and a GuideLiner catheter, was advanced close to the orifice of the coronary trunk. After successful rotablation with the regular protocol, the burr was removed using the Dynaglide protocol. Because of the risk of burr stack on the first arterial bend, we placed the tip of the Guideliner below this bend and using the standard Dynaglide protocol, the burr was advanced distally. In the present case, we used a 90 cm length 7 Fr guiding catheter with 7 Fr guiding extension (Guideliner, Teleflex Co) to deliver a 1.25 mm Rotablator burr to the postero-lateral branch of the right coronary artery. Due to the limited length of effective rotablation (advancer moving length – 7 cm), deliverability to the distal plaque location is impossible. In some cases, balloon predilatation is not enough for successful dilatation of the lesion and high speed rotational atherectomy is needed to perform the procedure. ![]() Extensive coronary calcification may affect procedural outcomes of coronary angioplasty, resulting in impaired device deliverability, especially in distal locations of the stenosis. ![]()
