Elixir Medical, a developer of advanced systems to treat coronary artery disease, announced the launch of the DynamX™ Coronary Bioadaptor System at centers of excellence in the Middle East. DynamX is an innovative device that enables physicians to treat a blockage of the coronary artery while freeing the artery to return to its normal function by adapting to vessel physiology.
Cardiovascular diseases (CDA) are on the rise in the region and are responsible for 34% of all deaths in the Middle East population. DynamX is designed to improve the treatment of one of the most prevalent cardiovascular conditions, coronary artery disease.
The first patient in the Middle East has been successfully treated with the DynamX Coronary Bioadaptor System by Arif Al Nooryani, Chief Executive Officer & Head of Cardiac Centre at Al Qassimi Hospital, Sharjah, United Arab Emirates. Apart from the UAE, the DynamX Bioadaptor will soon be available in the next few months in other countries in the region.
The DynamX Bioadaptor is a metal implant with a drug-eluting bioresorbable polymer that supports the coronary artery during healing, with radial strength similar to drug-eluting stents (DES). Over six months, the polymer coating dissolves, uncaging the bioadaptor and freeing the artery to move with the natural expansion and contraction of the artery, unlike DES. This has been shown to (a) maintain the ability for positive adaptive remodeling, (b) restore vessel function, and (c) allow for the vessel’s return towards baseline angulation.
“Coronary arteries naturally have the ability to expand with disease progression in order to maintain blood flow to the heart,” said Antonio Colombo, MD, co-principal investigator of the DynamX Mechanistic Clinical Study and director, Cardiac Catheterization Laboratory, Columbus Hospital, Milan and Coordinators Cardiac Catheterization Laboratories GVM Group, Care and Research, Lugo (RA), Italy. “Drug-eluting stents cage the coronary arteries and hinder this physiological response. DynamX is the first metallic coronary artery implant to demonstrate positive adaptive remodeling of the vessel, enabling it to expand to accommodate disease progression. This may improve longer-term clinical outcomes.”
The bioadaptor is designed to address the 2% – 3% major adverse cardiac event rate that occur with drug-eluting stents each year without plateau. The rigid design of a DES constrains, or “cages,” natural artery movement disabling its natural ability to accommodate disease progression, which has been associated with major adverse cardiac events (MACE). Long-term
studies have shown adverse event rates of 20% at 5 years3,4,5 and 40%-50% at 10 years. Clinical studies have demonstrated that a DES prevents positive adaptive remodeling, inhibits vessel compliance and dilation in response to the body’s changing blood flow needs, increases stresses on the vessel , and causes vessel straightening which has been associated with increased MACE.
Studies have shown that the DynamX Bioadaptor improves vessel function in several ways. It enables the vessel to accommodate disease progression by increasing vessel area, maintaining lumen diameter and preserving the lumen area and therefore blood flow to the heart, known as positive adaptive remodeling. DynamX restores vessel function and allows for normal vessel pulsatility and motion enabling it to provide more blood flow response to the body’s needs during physical activity. Its design also reduces stresses on the vessel and allows it to return to baseline angulation, which may reduce adverse events.
“We are launching DynamX in select countries in the Middle East, Asia, and other geographies at major centers of excellence, and Elixir is commencing multiple randomized clinical trials globally to build rigorous, clinically-based evidence for DynamX,” said Elixir Medical CEO Motasim Sirhan.
