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 ...

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 ...

Optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) leads to a larger minimum stent area but does not reduce the two-year rate of target vessel failure compared with ...

Angiography has limitations that make it difficult to determine the true artery size and the makeup of the plaque, and is suboptimal in determining whether the stent is fully expanded post-PCI and ...

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 ...

A new study could lead to more widespread use of imaging technique to improve survival and prevent complications. Using intravascular imaging (IVI) to guide stent implantation during complex stenting ...

PARIS — A percutaneous intervention strategy based on optical coherence tomography (OCT) provides greater procedural success than an angiography-based strategy for stent optimization in calcified ...

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 ...

Both the angiogram and angioplasty are useful tools when diagnosing and treating blockages and other heart issues. Both procedures are performed on an outpatient basis and are minimally invasive. If ...

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.
