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 ...

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 ...

City International Hospital has introduced intravascular ultrasound (IVUS) technology to help doctors assess coronary artery ...

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 ...

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 ...

Using intravascular imaging to guide stent implantation during percutaneous coronary intervention (PCI) in heart disease patients significantly improves survival and reduces adverse cardiovascular ...

Some evidence links hyperhomocystinemia and coronary artery disease. Folate supplementation decreases homocysteine levels, but clinical trials of supplementation to prevent restenosis after ...
