Use of Tornus for a Lesion That is Easily Balloon Crossable but No Expandible Despite High Pressure
نویسندگان
چکیده
Coronary angiography (CAG) was performed on a 78-year-old female patient due to class III angina. A calcified critical obstruction was demonstrated in the right coronary artery (RCA). An attempt at percutaneous transluminal coronary angioplasty (PTCA) failed to dilatate the lesion despite high balloon pressure. In a second attempt the lesion was dilatated with the balloon after implementing a tornus penetration device, and then a stent was implanted. A dissection occurred after the stent implantation and it was treated with another stent. The treatment of lesions that cannot be dilatated using conventional PTCA techniques and the role of the tornus penetration device in such cases are discussed.

[Usefulness of the Tornus® catheter in nondilatable coronary chronic total occlusion].
The treatment of coronary chronic total occlusions (CTO) remains a challenge for the interventional cardiologist. Failure of balloon angioplasty is the second more common cause of an unsuccessful procedure. We describe our experience with the use of the new Tornus® catheter (Asahi Intecc, Aichi, Japan) designed specifically for the treatment of "nondilatable" CTO. Between November 2008 and Marc...

BACKGROUND Balloon advancement and dilation through chronic total occlusion segment could be challenging in some cases after successful wire crossing. The purpose of this study was to evaluate efficacy and safety of Tornus catheter (Asahi Intecc; Aichi, Japan) in percutaneous coronary intervention of chronic total occlusion in hard or balloon-uncrossable chronic total occlusion. METHODS The p...

Background: Recent pre-clinical and clinical studies indicate that irradiation in the dose range of 15 to 30 Gy can reduce rate of restenosis in patients who have undergone an angioplasty. The use of filled balloon with radioactive solution was proposed as one of the possible intravascular irradiation techniques. Materials and Methods: The Monte Carlo N-particle Transport Code (MCNP4b) was used...

Balloon angioplasty for aortic coarctation was introduced in 1979 for the fust time.1 This procedure soon became the choice treatment for restenosis of operated coarctation,2-5 but remains controversial for native (unoperated) coarctation. However, it seems to be rapidly becoming the intervention of choice for relief of unoperated coarctation as well. In this study, we evaluate the outcome ...

Introduction C total coronary occlusion remains one of the limitations of percutaneous transluminal coronary angioplasty, and few therapeutic devices are specifically designed to address this problem. Despite advances in device technology, the management of resistant, calcific lesions remains one of the greatest challenges in successful chronic total coronary occlusion intervention. Established...
