What is RCA stent?

What is RCA stent?

A coronary artery stent is a small, metal mesh tube that expands inside a coronary artery. A stent is often placed during or immediately after angioplasty. It helps prevent the artery from closing up again. A drug-eluting stent has medicine embedded in it that helps prevent the artery from closing in the long term.

What drugs are in a drug-eluting stent?

Soon thereafter, a series of trials of paclitaxel-eluting stents led to FDA approval of the Taxus stent in 2004. Both sirolimus and paclitaxel are natural products, making the drug-eluting stents a specific kind of application totally dominated by drugs directly derived from natural sources.

What is PCI to RCA?

Percutaneous Coronary Intervention (PCI, formerly known as angioplasty with stent) is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup, a condition known as atherosclerosis.

What does a drug-eluting stent do?

Drug-eluting stents prevent a coronary artery from narrowing again after angioplasty. They are coated with medicine that prevents scar tissue from growing into the artery.

How long does the drug last in a drug-eluting stent?

Conclusions. Our study findings suggest that the long-term survival (to 3 years) of patients with drug-eluting stents remains favourable overall. It is not measurably worse than that of patients with bare-metal stents.

How much do drug-eluting stents cost?

Each drug-eluting coronary stent costs a hospital an average of $2,500, about $1,800 more than the cost of a similar bare-metal stent.

Can RCA be stented?

The ostium of the right coronary artery (RCA) is not a tubular structure . Hence, sizing, positioning and flaring the stent in the ostium of the RCA demands considerable skill, and occasionally will not yield optimal results.

How long will a drug-eluting stent last?

Do drug-eluting stents have side effects?

Potentially dangerous side effects of drug-eluting stents are adverse drug interactions, incomplete stent apposition and increased in-stent thrombosis rates. Demonstration of long-term efficacy is mandatory since in some animal studies a delayed healing has been observed.
