“Metal-less” stent: Its reality
Mumbai,4th March, 2016: Dr. Brajesh Kunwar, MD, DM-Cardiology (CMC, Vellore), Consultant Interventional Cardiology
A 50 years old lady suffering from a heart attack was admitted in the ICU in SevenHills Hospital. The case seemed to be one of the regular heart attack cases and she underwent a coronary angiogram. The angiogram revealed that there was a 99% blockage in her right coronary artery.
A bioabsorbable scaffold was used in the place of stents, and the blockage was thus successfully opened. The regular stents available in the markets have metals which remain in the body forever. Their presence also affects the elastic properties of the segment of vessel they are applied for. However, vascular scaffold do the repair work and over a period of 1-2 years, they totally disappear leaving the patient’s native vessel behind.
The major problem with metallic stents is the need to use blood thinning agents throughout the life in most of the cases. Since the vascular scaffold gets absorbed after 1-2 years, the blood thinning agents can be stopped post this duration.
“Using novel techniques and instruments, many drawbacks of previous angioplasty and stents can be overcome with experience!” Dr. Brajesh exclaimed.
