Dr. Chan continued, As technology evolves, there are many in our field that feels like this will be the next generation.
Dr. Chan stated, It allows us to theoretically have less inflammation. Because of that, it also reduces the risk of clot formation that can form late on stents because of that metal exposure.
LOS ANGELES, Calif. Ivanhoe Newswire Cardiologists excitement over an absorbable, dissolvable stent that hit the market last year is ding a bit. An FDA study shows that patients with it have higher rates of heart attack and thrombosis. A doctor in Los Angeles is standing by the new technology when its used by the right practitioners in the right patients.
Michael Chan, MD, an Interventional Cardiologist at St. Joseph Hospital in Orange, CA used the Absorb stent for Charles, who already has traditional metal stents. Its made of polylactide, which is similar to whats in dissolvable stitches. The stent dissolves in three years, so the artery is flexible again.
Nineteen percent of people in the study had arteries that are too small for the device under usage guidelines. Removing their results equalizes findings.
In May, Abbott laboratories restricted use of the Absorb stent to clinical use at select sites while it monitors implantation techniques and training. Some cardiac US cilities have stopped using the stent until more study is done. Dr. Chan has no financial interest in the stent or Abbott labs.
Dr. Chan will keep using the Absorb stent on patients who fit the stricter criteria, while the FDA does more study.
But an FDA review showed an percent rate of cardiac problems like heart attack and a . percent rate of blood clots after two years with the Absorb stent. This compares with . percent and . percent with a metal stent. Abbott labs and Dr. Chan say the right implantation technique and the right patients minimize risk.
Tasso explained, I mean, I thought it was an elephant sitting on my chest. Thats the first time I had experienced any pain.
I think that if its not used in the proper setting, then the risks are higher. Weve seen that in smaller vessels that the heart attack risk as you mentioned, and risks of clotting are higher, said Dr. Chan.
Sixtythreeyearold Charles Tasso was at his dialysis center when his heart went into Afib.
