A study published in the Journal of the American College of Cardiology, based on data from the Symplicity HTN-2 trial, suggests that renal denervation may be a cost-effective method of managing resistant hypertension and may result in a reduction in cardiovascular morbidity and mortality in the long term.
Electrophysiologist Clemens Jilek, German Heart Centre Munich, Germany, presented on how the technique of renal ablation could affect the renal artery and how renal denervation could be improved at CIRSE 2012 (15–19 September, Lisbon, Portugal) in a presentation titled “How bad is radiofrequency for the renal arteries?”
Key members of the Society of Interventional Radiology (SIR) have praised a new dual certificate for diagnostic radiology and interventional radiology, saying it recognises interventional radiology as a “a new form of medicine”.
At CIRSE 2012 (Lisbon, Portugal, 15–19 September), Philips and Biocompatibles announced a collaboration to advance the use of image guidance to control the delivery of beads during the arterial embolization of hypervascularised tumours.
The US Food and Drug Administration (FDA) has given 510(k) clearance to Access Scientific for its 4Fr Nanopuncture Powerwand.
On 11 September, the American Board of Medical Specialties (ABMS) recognised the unique interventional radiology skill set with the new dual certificate in interventional radiology and diagnostic radiology. The Society of Interventional Radiology (SIR) has hailed the affirmation of the specialty s role in patient care.
Advocate Health Care, the largest integrated health care system in the state of Illinois, USA, and GE Healthcare have announced a joint effort to help further reduce radiation dose in computed tomography (CT).
Is one device more effective than the other, with respect to radioembolization for hepatocellular carcinoma with or without portal vein thrombosis, metastatic colorectal cancer and neuroendocrine tumours? Examining the medical literature, the answer is “no”, Robert Lewandowski, Chicago, USA, said.
A recent clinical investigation from The Netherlands, published in the journal Cardiovascular and Interventional Radiology (CVIR), has revealed that the use of a validated comprehensive patient safety checklist in interventional radiology in a tertiary referral centre led to a significant decrease in process deviations and procedure postponements.
Surefire Medical has received CE mark approval for its Surefire Infusion System, a next generation device for chemo- and radioembolization procedures. The company has announced that the launch of this product will be effective immediately.
Patients with uncontrolled renovascular hypertension saw a significant improvement in their blood pressure with renal artery stenting. The multicentre HERCULES trial, evaluating the safety and effectiveness of the RX Herculink Elite Stent (Abbott Vascular), found that patients with higher blood pressure levels at baseline had the most dramatic reduction in blood pressure following intervention. Results have been published in the September issue of Catheterization and Cardiovascular Interventions.
“We need to be very careful not to kill a promising technology with incorrect patient selection,” Pierre-François Plouin, Paris, France, warned delegates at the EuroPCR Great Debate 2012 on renal denervation. In the debate, Plouin and four other experts in interventional cardiology, interventional radiology and nephrology agreed that identifying the right group of patients is key for the future of the technique. The group also discussed patient compliance to medical therapy, clinical data associated with the procedure and the balance between risk and benefit.
The US Food and Drug Administration (FDA) has granted 510(k) clearance to AngioDynamics for its BioFlo peripherally inserted central catheters (PICCs) with Endexo technology designed to reduce the accumulation of catheter-related thrombus on, and in, the catheter.
Results from the EnligHTN I trial have shown that the EnligHTN renal denervation system (St Jude Medical) is safe and effective for the treatment of resistant hypertension. Data released during the ESC Congress 2012 demonstrated that on average patients with resistant hypertension experienced a rapid systolic blood pressure reduction of 28 mmHg points after 30 days that remained stable with a reduction of 27 mmHg points three months after treatment.
On 29 August, the UK’s National Institute for Health and Clinical Excelence (NICE) published guidance supporting the use of contrast-enhanced ultrasound with SonoVue (Bracco) to diagnose liver cancer.
