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 ...

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 ...

Angiogram and angioplasty are heart procedures. Angiogram diagnoses heart vessel issues using X-rays and dye. Angioplasty treats blockages by opening arteries with a balloon and stent. Angiograms ...

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 ...

When IVUS did not outperform angiography for guiding percutaneous interventions in two trials, the results offered more questions than answers.

An “optical biopsy” of intravascular plaque during stenting is more effective at reducing the rate of restenosis or thrombosis in people with moderately or severely calcified lesions than angiography ...

The use of intravascular ultrasound (IVUS) to guide stent placement in percutaneous coronary intervention (PCI) leads to better clinical outcomes than use of angiography guidance, according to a ...

When a Cardiologist tells you that you have“90 percent blockage,” the mind goes straight to fear. Most families immediately ask three questions. Is this a heart attack. Do I need a stent right now.

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 ...
