Handheld optical coherence tomography angiography

Biomedical Optics Express, 2017
We developed a handheld optical coherence tomography angiography (OCTA) system using a 100-kHz swept-source laser. The handheld probe weighs 0.4 kg and measures 20.6 × 12.8 × 4.6 cm3. The system has dedicated features for handheld operation. The probe is equipped with a mini iris camera for easy alignment. Real-time display of the en face OCT and cross-

Influence of the arterial elastic component on the response to balloon angioplasty in femoral arteries of a healthy porcine model

Animal Models and Experimental Medicine, EarlyView.
This study evaluates the role of elastin in vascular response 28 days after balloon angioplasty using uncoated and paclitaxel‐coated balloons in a healthy porcine model. The results show higher elastin content in external femoral arteries, which is inversely correlated with vascular injury, inflammation, smooth muscle cell loss, proteoglycan and fibrin

Advances in Doppler optical coherence tomography and angiography [PDF]

Translational Biophotonics, 2019
AbstractSince the first demonstration of Doppler optical coherence tomography (OCT) in 1997, several functional extensions of Doppler OCT have been developed, including velocimetry, angiogram, and optical coherence elastography. These functional techniques have been widely used in research and clinical applications, particularly in ophthalmology. Here,

Coronary Plaque Characteristics Assessed by Optical Coherence Tomography and Plasma Lipoprotein(a) Levels in Patients With Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood. Aims This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high‐risk subset of patients ...

The Impact of Underlying Plaque Characteristics Following the Third‐Generation Resorbable Magnesium Scaffold Implantation: An Intravascular OCT Assessment up to 12‐Months

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Third‐generation resorbable magnesium scaffold (RMS) was developed with stronger mechanical properties and thinner struts compared to its predecessor. This study aimed to assess the influence of the OCT‐derived underlying plaque characteristics on in‐scaffold late lumen loss (LLL) in patients treated with RMS up to 12‐months ...
