The renal denervation hypothesis of hypertension was initially viewed with some skepticism, and Dublin-based Medtronic plc. endured a major setback when clinical trial data failed to make a compelling case for approval for the Symplicity Spyral. However, the company finally landed an FDA approval for the device, opening the gates to a new and significant market opportunity even with competition already on the market.
Recor Medical Inc. finally received U.S. FDA approval for its Paradise ultrasound renal denervation (RDN) system for the treatment of hypertension after more than ten years of research and clinical trials. Paradise is the first RDN system to reach the U.S. market, and its approval is good news for the technology after years of disappointment in the data from trials and concerns over the efficacy of RDN devices.
The age of renal denervation as a treatment for hypertension may have finally arrived in the U.S. with the affirmative U.S. FDA advisory vote for the Paradise system for renal denervation by Recor Medical Inc., of Palo Alto, Calif. The 12-member advisory committee vote unanimously that the data suggested the ultrasound-based device was safe and voted 8-3 in support of the Paradise’s efficacy, an outcome that the agency may find difficult to refute, given the large public health impact of hypertension in the U.S.
The European Society of Hypertension (ESH) has recommended that renal denervation (RDN) be offered as an adjunctive therapy to patients with resistant hypertension. Releasing new and updated guidelines on the management of arterial hypertension, the ESH said recent randomized controlled trials showed that endovascular RDN can be associated with a significant, albeit not marked, office and ambulatory blood pressure reduction in patients with uncontrolled hypertension.
In an unexpected turn of events, Medtronic plc presented results from the Symplicity HTN-3 trial at year 3 showed sustained reductions in blood pressure with radiofrequency renal denervation (RDN) for resistant hypertension, contrary to the trial’s results at the six-month mark—and it wasn’t alone in showing positive results for the procedure.
Despite the morbidity associated with coronary artery bypass graft, this procedure has never been entirely displaced by percutaneous coronary intervention. The results from the latest in a series of studies does not seem to help the case for drug-eluting stents (DES) for patients with three-vessel disease, as the data from this study failed to demonstrate non-inferiority for DES devices implanted with the help of fractional flow reserve measurement to ensure optimal stent placement.
Sonivie Ltd. has won breakthrough device designation from the U.S. FDA for the Therapeutic Intra-Vascular Ultrasound (TIVUS) system for renal artery denervation (RDN) to treat resistant hypertension. At the same time, the company revealed that it has bought the remaining intellectual property and other assets related to the use of the TIVUS System from Cardiosonic Inc.
