Catheterization and Cardiovascular Interventions. ![]() SIGN IN for Pricing and Availability Representative image. Post-dilation to the two stents was performed by 4.5x12mm NC balloon.IVUS: Adequate apposition of the stent struts over os to d-RCA. The cross sectional area over RCA ostium was 16.38mm2 with diameter 3.30-5.45mm. The minimal stent area was 11.63mm2 with diameter 2.85-5.08mm at m-RCA.-The final angiography showed <10% residual stenosis over m-RCA stent with TIMI 3 distal runoff. The utility of a guideliner catheter in retrograde percutaneous coronary intervention of a chronic total occlusion with reverse cartthe capture technique. GuideLiner Catheters are intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/ or peripheral vasculature, to. 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. A 4.0x43mm DES was deployed to m to d-RCA with the GuideLiner catheter assisted.-A 4.0x32mm DES was deployed to os to m-RCA with distal stent overlapping and proximal stent minimal protruding out of the RCA ostium. ![]() Rotational atherectomy (RA) which is usually accomplished with the Rotablator burr can facilitate. Dissection flap with lumen collapse was noted.-Under balloon assisted, a GuideLiner (6 Fr.) catheter was delivered to p-RCA to strengthen the back-up force.-The stenotic lesion at os to d-RCA was dilated by 4.0x15mm NC balloon.-The GuideLiner advanced to m-RCA using balloon assisted tracking technique by 2.0x20mm balloon. In 2009, the GuideLinerĀ® Catheter revolutionized the concept of guide extension, creating new possibilities in interventional cardiology. The GuideLiner is a rapid exchange mother and child guide extension catheter that allows deep and subselective intubation of the target vessel allowing for improved support during delivery of stents in highly tortuous vessels 1 3. Allows delivery of devices into distal vessels New V2 Improvements all-polymer collar for increased flexibility and. Flexible coaxial guide liner that allows guide extension into vessels for deep seating Simplified mother and child technique for use in challenging interventions. The os to d-RCA was pre-dilated by 2.0x20mm balloon.IVUS: There was a dissected flap at os-RCA and the cracked calcification at m-RCA lesion was noted. The MLA at os-RCA was 4.99 mm2 with diameter 1.78-3.55 mm.-The lesion from os to d-RCA was dilated by 3.0x15mm NC balloon and 4.0x15mm NC balloon. In this case report, we applied the Guideliner mother-and-child catheter (Vascular Solutions, Minneapolis, Minnesota, USA) to successfully treat a case of CTO. Teleflex 5571 GuideLinerĀ® V3 Catheter, 6Fr, 150 cm, Box of 01. The microcatheter was removed via assistance of an Extension wire. The RCA ostium was engaged by SAL 1.0 guiding catheter.-A SION Black wire in a FineCross microcatheter was used to wire through the critical stenotic lesion at m-RCA and advanced to PDA.
