Integrated intravascular ultrasound and optical coherence tomography technology: a promising tool to identify vulnerable plaques [INVITED PAPER]

Journal of Biomedical Photonics & Engineering, 2016
Heart attack is mainly caused by the rupture of a vulnerable plaque. IVUS-OCT is a novel medical imaging modality that provides opportunities for accurate assessment of vulnerable plaques in vivo in patients.

Coronary Plaque Boundary Enhancement in IVUS Image by Using a Modified Perona-Malik Diffusion Filter

International Journal of Biomedical Imaging, 2014
We propose a modified Perona-Malik diffusion (PMD) filter to enhance a coronary plaque boundary by considering the conditions peculiar to an intravascular ultrasound (IVUS) image. The IVUS image is commonly used for a diagnosis of acute coronary syndrome

Intravascular Ultrasound Guiding Percutaneous Coronary Interventions in Complex Higher Risk-Indicated Patients (CHIPs): Insight from Clinical Evidence

Reviews in Cardiovascular Medicine
Intravascular ultrasound (IVUS) in percutaneous coronary intervention (PCI) has transformed the management of complex higher risk-indicated patients (CHIPs), representing a pivotal advancement in high-risk procedure navigation.

Successful Intravascular Ultrasound-Guided Transradial Coronary Intervention with a 4Fr Guiding Catheter

Case Reports in Cardiology, 2016
Minimizing the catheter size can reduce vascular access complications and contrast dye usage in coronary angiography. The small diameter of the 4Fr guiding catheter has limited the use of several angioplasty devices such as intravascular ultrasound (IVUS)

Effect of ticagrelor versus clopidogrel after implantation of drug-eluting stents guided by either intravascular ultrasound or angiography in patients with acute coronary syndrome—propensity score matching analysis

BMC Cardiovascular Disorders
Background The effect of different dual antiplatelet therapies on thrombotic events on the background of intravascular ultrasound (IVUS) guidance is unclear. We investigated whether ticagrelor can provide any additional benefit to clopidogrel in reducing
