Circumventing the resolution-time tradeoff in Ultrasound Localization Microscopy by Velocity Filtering [PDF]

arXiv, 2021
Ultrasound Localization Microscopy (ULM) offers a cost-effective modality for microvascular imaging by using intravascular contrast agents (microbubbles). However, ULM has a fundamental trade-off between acquisition time and spatial resolution, which makes clinical translation challenging.

INtravaScular OptIcal Frequency Domain ImaGing EvaluaTion of the Femoropopliteal Lesion With JETSTREAM Atherectomy (INSIGHT JETSTREAM)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background There have been no prior reports of detailed evaluations using intravascular imaging during Jetstream treatment. Aims This study, therefore, aimed to investigate the effects of calcification characteristics and wire bias on lumen gain in Jetstream atherectomy using optical frequency domain imaging (OFDI). Methods This study enrolled

Intracoronary Lithotripsy

JACC: Case Reports, 2021
Percutaneous coronary intervention was performed in a flush in-stent right coronary artery chronic total occlusion. Successful retrograde recanalization was performed but the lesion was balloon undilatable as confirmed by intravascular ultrasound.

SUMNet: Fully Convolutional Model for Fast Segmentation of Anatomical Structures in Ultrasound Volumes [PDF]

arXiv, 2019
Ultrasound imaging is generally employed for real-time investigation of internal anatomy of the human body for disease identification. Delineation of the anatomical boundary of organs and pathological lesions is quite challenging due to the stochastic nature of speckle intensity in the images, which also introduces visual fatigue for the observer.

Impact of Diabetes on Long‐Term Outcomes of Percutaneous Coronary Intervention for Coronary Bifurcation Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) is a well‐known risk factor for cardiovascular diseases, including coronary artery diseases (CAD). Complex percutaneous coronary intervention (PCI) such as PCI for bifurcation lesions often yields poor outcomes, especially in DM patients.

Clinical and Technical Predictors of Treatment Success After Coronary Intravascular Lithotripsy in Calcific Coronary Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) is increasingly used to treat coronary artery calcification (CAC). This study aimed to identify clinical and procedural factors associated with IVL treatment success. Methods This retrospective analysis included 454 patients (73 ± 9 years, 75% male) treated with IVL from the multicenter BENELUX‐IVL ...

Intravascular ultrasound is a key diagnostic tool in subclavian vein varicosity

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
Varicose veins of the neck are far less common than lower extremity varicosities. Often, neck varicosities can be a sign of a more central venous obstruction.

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 ...

Ultrasound Appearance of Intravascular Uterine Smooth Muscle Tumor of Uncertain Malignant Potential (STUMP): A Case Report

Diagnostics
A 43-year-old patient with a history of uterine fibromatosis was referred to our hospital for menometrorrhagia and pelvic pain. At the pelvic ultrasound, a highly-vascularized myometrial lesion in volumetric increase was described.

Trends and Outcomes Following Percutaneous Coronary Intervention in Patients With Myeloproliferative Neoplasms: Insights From National Database

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Myeloproliferative neoplasms (MPN) are associated with an increased cardiovascular risk including acute coronary syndrome. However, there is a lack of comprehensive data regarding the rate of percutaneous coronary intervention (PCI), as well as the in‐hospital characteristics and outcomes for MPN patients.
