There have been vast technological advances that have enabled the final frontier of the aorta, the diseased ascending aorta and arch, to be treated by completely endovascular means. Simultaneously, there have also been advances in open repair. Also, with perioperative stroke remaining a principal risk with TEVAR, the high incidence of cerebral embolisation with the procedure is a problem that needs wider recognition, delegates heard yesterday.
A clinical trial evaluating Eluvia Drug-Eluting Vascular Stent System (Boston Scientific) has met its primary endpoint with more than 94% of the lesions treated remaining open at nine months post implantation. This was accompanied by a target lesion revascularisation rate of less than 4%.
Intact Vascular has announced the publication of the first clinical experience with supporting preclinical data in the Journal of the American College of Cardiology: Cardiovascular Interventions. The article “Early experimental and clinical experience with a focal implant for lower extremity post-angioplasty dissection”, reveals the potential of the Tack endovascular system for the repair of arterial dissections following percutaneous transluminal angioplasty.
Yesterday, for the first time, the Charing Cross International Symposium broadcast peripheral live cases that were directly linked to data presented the previous day on the theme of peripheral arterial controversies. The aim of the course was to provide delegates with opportunities to learn techniques to achieve the best results with the approaches discussed in the data.
The INNOVATION study found that the rate of freedom proximal type I endoleaks and the rate of freedom from reintervention in patients who underwent endovascular aortic aneurysm repair (EVAR) with the Incraft (Cordis) device was, respectively, 100% and 95%, at three years. In this interview, CX Daily News speaks to Giovanni Pratesi (Florence, Italy)—who presented the data at CX yesterday—about Incraft and the three-year results.
According to Janet Powell, Imperial College London, UK, the highest risk factors for rupture of abdominal aortic aneurysms (AAA) are female gender, smoking, increasing age and mean arterial pressure, but there are still few useful indicators of how to manage screen-detected aneurysms to stop them enlarging. Powell put forward this view during yesterday’s Abdominal Aortic Controversies Main Programme which explored epidemiology, indications and medical management of abdominal aortic aneurysms.
Results from the 12-month data of the randomised controlled IMPROVE trial, presented for the first time at CX 2015 (28 April–1May, London, UK), show that an endovascular strategy is cost-effective when compared to open repair in the treatment of ruptured abdominal aortic aneurysms. The one-year data also revealed that the endovascular strategy conferred no survival benefit over open repair, except a trend towards benefitting women. It also showed that the endovascular strategy enabled more patients to be discharged from hospital to home, and significantly faster than with open repair. Patients also have an excellent quality of life with endovascular strategy, if they survive the rupture, delegates heard.
The 12-month results of patients treated with the Nellix system are encouraging for the development of endovascular sealing (EVAS) as the next gold standard treatment, according to Matt Thompson (London, UK), with a low overall endoleak rate and an acceptable reintervention rate.
Among hospitalised patients with severe acute pulmonary the use of a retrievable inferior vena cava filter plus anticoagulation compared with anticoagulation alone did not reduce the risk of recurrent pulmonary embolism or death, according to a study in JAMA.
The use of bioresorbable scaffolds is the only complete solution for the superficial femoral artery, argued Andrew Holden, Auckland, New Zealand, in yesterday’s Peripheral Arterial Controversies session.
The CX Innovation Showcase is dedicated to highlighting what it takes for a physician-inventor to succeed and for innovative ideas in the vascular and endovascular arena to thrive. Yesterday’s session brought together leading industry experts, physician-inventors, engineers, medtech investors and start-up companies all focused on improving vascular disease management.
Twelve-month results from the randomised, multicentre DEFINITIVE AR pilot study suggest that there is a benefit to adding directional atherectomy in long and calcified lesions prior to using a drug-coated balloon in comparison to the use of a drug-coated balloon alone. Data from the trial were presented yesterday by Thomas Zeller, Bad Krozingen, Germany, who is a study principal investigator alongside Gunnar Tepe, Rosenheim, Germany.
At this year’s Charing Cross Symposium, Cordis is launching the Outback Elite re-entry catheter, an enhanced version of the Outback re-entry catheter that received the CE mark earlier this week. According to the company, Outback Elite provides more control and precision and includes additional features to enable re-entry into the most complex lesions whilst facilitating positioning and delivery
Drug-coated balloon technology is unlikely to be a successful “stand alone” treatment for the majority of medium and long length superficial femoral artery lesions, the voting results from CX2015 implied. The voting showed that the audience felt that drug-coated balloon use was best suited to short lesions. The randomised controlled trial data for drug-coated balloons are mostly based on short lesions and 57% of the audience voted “no” to the question, “Is drug-eluting balloon technology likely to be a successful standalone treatment for the majority of medium and long length superficial femoral artery lesions?” The session in which the vote was held was titled “Leaving nothing behind” and also saw the presentation of the ILLUMENATE first-in-human study 24-month results. These were favourable for the Stellarex drug-coated balloon (Spectranetics), and came close on the heels of updates on the Lutonix drug-coated balloon (Bard) and the IN.PACT Admiral drug-coated balloon (Medtronic). Atherectomy as a pretreatment also received a boost.
CX’s new Edited Live Case session, which aims to highlight the technical aspects of the aortic and carotid main programme, was launched yesterday with a selection of cases exploring how to apply different techniques in complex situations to achieve the optimum result for the patient.
