WASHINGTON, DC—A three-way comparison of optical coherence tomography (OCT), intravascular ultrasound, and angiography has come up with mixed results when it comes to choosing the best imaging ...

No IVUS was performed before stent placement in either group. In the angiography-directed (AG) arm, procedural success was defined as <10% stent diameter stenosis compared with the distal reference ...

Abbott aims to build optical coherence tomography into a preferred tool for guiding the placement of stents that increase blood flow to the heart muscle. But a pair of major late-breaking studies ...

A new method for determining whether patients with heart disease need coronary stents or bypass surgery is more effective than the angiogram, which is currently used, according to research from ...

SAN DIEGO, CA—IVUS-guided implantation of drug-eluting stents results in lower rates of target vessel failure (TVF) by 1 year compared to angiography-guided procedures, according to results from a new ...

Doctors may be implanting too many artery-opening stents and could improve patient outcomes -- and ultimately save lives -- if they did more in-depth measurements of blood flow in the vessels to the ...

STANFORD, Calif. — Doctors may be implanting too many artery-opening stents and could improve patient outcomes — and ultimately save lives — if they did more in-depth measurements of blood flow in the ...

A new method for determining whether patients with heart disease need coronary stents or bypass surgery is more effective than the angiogram, which is currently used, according to research from ...

Quantitative magnetic resonance angiography is a promising screening tool to detect in-stent stenosis with high sensitivity and specificity, according to a new study. Great advances have been made in ...

Millions of Americans have had stents — small wire cages — inserted in their coronary arteries to prop them open. And many are convinced the devices are protecting them from heart attacks. After all, ...
