[Kolkata]Hearts Patients,Cursed With Artery Blockade May Be Blessed With Drug-Eluting[New]Stents.At Present Plain Vanilla Bare Metal Stent Is Used
India, which has one of the largest concentration of patients of coronary artery disease in the world, will see the introduction of a new generation of drug-eluting stents.
“From a plain vanilla bare metal stent to the new generation Resolute Onyx drug eluting stents, it is a kind of revolution in stent technology,” Chief of Adult Cardiology of Budapest-based Gottsegen Gyorgy Hungarian Institute of Cardiology Peter Andreka said.
Resolute Onyx DES which features the Core Wire Technology has thinner struts to help improve deliverability without compromising radial and longitudinal strength of the stent.
“It has proven long-term safety and efficacy and has no increased risk for stent thrombosis with interruption or discontinuation of dual antiplatelet therapy (DAPT) after a month,” Andreka, who has treated around 80 patients with CAD using Resolute Onyx DES at his Institute in Budapest,
Core Wire Technology is the next new DES advancement after Continuous Sinusoid Technology (CST). The uniqueness is that the wrapped in a Cobalt Alloy shell, the denser, more radiopaque inner core material allows for improved visibility during procedure, referred to as radiopacity.
The Cobalt alloy shell maintains the mechanical performance and structural strength of the stent material.
“Core Wire Technology is an exciting innovation that will have measurable impact on clinical practice today and tomorrow,” he said.
“When coronary stents fail to cross a tortuous anatomy they become ideal candidates for surgical revascularisation to provide relief from angina due to blocked artery. This is when Resolute Onyx DES comes into play due to its superior deliverability,” the Hungarian Cardiologist said.
A stent is a small mesh tube that’s used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from heart to other parts of the body.
A stent is placed in an artery as part of a procedure called percutaneous coronary intervention (PCI), also known as coronary angioplasty. PCI restores blood flow through narrow or blocked arteries. A stent helps support the inner wall of the artery in the months or years after PCI.
Stents usually are made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries.
Some stents are coated with medicine that is slowly and continuously released into the artery. These stents are called drug-eluting stents. The medicine helps prevent the artery from becoming blocked again.
