Boston Scientific Receives CE Mark for Lotus Valve System
TAVR device offers precise positioning and placement, offering physicians unprecedented control
October 31, 2013
October 31, 2013 — Boston Scientific Corp. has received CE mark for its Lotus Valve System, a transcatheter aortic valve replacement (TAVR) technology. This key approval offers an effective new treatment alternative for patients with severe aortic stenosis at high risk with surgical valve replacement.
The Lotus Valve System is immediately available to select centers in Europe, with commercial site expansion accelerating as physicians and centers become fully trained. It is designed to provide physicians increased control during implantation and to help provide a more precise, predictable procedure. It is the only aortic valve device that can be assessed in its final position prior to release while maintaining the ability for the physician to reposition or fully resheath and retrieve the valve. The Lotus Valve System also incorporates Adaptive Seal technology designed to minimize aortic regurgitation.
"The ability to initially position the Lotus Valve precisely and, if needed, to easily reposition or fully retrieve the valve provides the operator with remarkable control," said Ian Meredith, director of MonashHeart at Monash Medical Centre, Melbourne, Australia and principal investigator, REPRISE II trial. "Combined with early and often complete elimination of aortic regurgitation as observed in REPRISE II, the unique features of the Lotus Valve technology represent a significant step forward in the percutaneous treatment of eligible patients with severe symptomatic aortic stenosis."
Data presented at the PCR London Valves course in September demonstrated the Lotus Valve System met the primary performance endpoint for the first 60-patient cohort and was implanted successfully in all patients with no cases of severe paravalvular regurgitation. In 76.1 percent of patients, there was no corelab adjudicated paravalvular regurgitation at six months.
"Results from the REPRISE II trial highlight the promise behind the Lotus Valve System, especially related to avoiding moderate or severe paravalvular leaks," said Nicolas Van Mieghem, M.D., Erasmus Medical Center, Rotterdam, Netherlands. "In addition to providing a new treatment option for TAVR, the Lotus Valve has the potential to improve clinical outcomes by minimizing paravalvular leaks."
The Lotus Valve System comes pre-loaded on a transfemoral delivery system, which is inserted through a small incision in the leg. Available in a 23 mm and 27 mm size, the Lotus Valve System can treat patients with aortic annulus sizes from 20 mm to 27 mm. The Lotus Valve System is an investigational device in the United States and Japan, and is not available for sale in those countries.
