Insights
The Tornus® catheter offers a safe solution for treating "nondilatable" coronary chronic total occlusions (CTO) when balloon angioplasty fails. This new device demonstrated high success rates and no major adverse events in a patient follow-up study.
Area of Science:
- Interventional Cardiology
- Vascular Medicine
- Medical Device Technology
Background:
- Coronary chronic total occlusions (CTO) present significant challenges in interventional cardiology.
- Failure of balloon angioplasty is a common reason for unsuccessful CTO procedures.
- A need exists for specialized devices to treat "nondilatable" CTO lesions.
Purpose of the Study:
- To evaluate the safety and feasibility of the new Tornus® catheter.
- To assess the efficacy of the Tornus® catheter in treating "nondilatable" CTO lesions.
- To report outcomes in patients who failed conventional balloon angioplasty for CTO.
Main Methods:
- Prospective case series of 17 patients with "nondilatable" CTO.
- Patients treated with the Tornus® catheter after failed balloon angioplasty.
- Clinical follow-up for a median of 573 days.
Main Results:
- The Tornus® catheter was successfully used in 15 out of 17 patients (88.2%).
- No complications were reported during the use of the Tornus® catheter.
- No major adverse events were documented during the follow-up period.
Conclusions:
- The Tornus® catheter is a safe and feasible option for CTO treatment.
- It is effective in cases where balloon angioplasty has been unsuccessful.
- This device addresses a critical unmet need in interventional cardiology for CTO management.
Abstract:
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 March 2010, 17 patients (age 62 years, 88% men, 82% dyslipidemia, 52% hypertension, 29% diabetes) were treated in whom balloon dilatation had failed after crossing the lesion with the guide. The use of Tornus® catheter was successful without complications in 15. All patients underwent clinical follow-up (median, 573 days) with no documented major adverse events. The use of the Tornus® catheter is safe and feasible in those patients with CTO lesions in whom balloon angioplasty has been unsuccessful.
