Intravascular visualization methods in estimating vasculopathy of a transplanted heart

Вестник трансплантологии и искусственных органов, 2019
One of the pathognomonic signs of сardiac allograft vasculopathy is concentric intimal hyperplasia, which can be assessed by intravascular imaging techniques.

Medical Information Embedding in Compressed Watermarked Intravascular Ultrasound Video [PDF]

Scientific Bulletin of the Politehnica University of Timisoara - Transactions on Electronics and Communications p-ISSN 1583-3380 , vol. 57(71), no. 2, 2012, 2013
In medical field, intravascular ultrasound (IVUS) is a tomographic imaging modality, which can identify the boundaries of different layers of blood vessels. IVUS can detect myocardial infarction (heart attack) that remains ignored and unattended when only angioplasty is done.

Impact of Post Percutaneous Coronary Intervention Fractional Flow Reserve on 5‐Year Clinical Outcomes (The FFR SEARCH Study)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) can be used to evaluate procedural success and to guide stent optimization. Several studies have demonstrated that lower FFR after stent implantation is associated with increased adverse event rates up to 2 years.

EXPERIENCE OF CLINICAL USE OF ULTRASOUND GUIDANCE FOR CERVICAL PLEXUS BLOCK IN RECONSTRUCTIVE CAROTID SURGERY

Вестник анестезиологии и реаниматологии, 2019
The surface block of cervical plexus in combination with general anesthesia provides nociceptive protection at all stages of the surgery. However, its use is associated with the risk of puncture of large vessels of the neck and resulting complications ...

Impact of Coronary Calcification on Complete Revascularization in Patients With Acute Coronary Syndrome and Multivessel Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary calcification is a well‐known marker of atherosclerotic plaque burden and a determinant of stent under expansion with unfavorable long‐term outcomes. Aims This sub study of the randomized BIOVASC trial aimed to compare immediate complete revascularization (ICR) and staged complete revascularization (SCR) in patients with ...

Capabilities of intravascular imaging techniques in the diagnosis of cardiac allograft vasculopathy: Literature review

Вестник трансплантологии и искусственных органов
Cardiac allograft vasculopathy (CAV) is a coronary heart disease (CHD), arising after an orthotopic heart transplant (OHT), and it is one of the leading causes of death in heart recipients. The probability of death is 10%.

Globally Optimal Surface Segmentation using Deep Learning with Learnable Smoothness Priors [PDF]

arXiv, 2020
Automated surface segmentation is important and challenging in many medical image analysis applications. Recent deep learning based methods have been developed for various object segmentation tasks. Most of them are a classification based approach, e.g. U-net, which predicts the probability of being target object or background for each voxel.

Automated detection of vulnerable plaque in intravascular ultrasound images [PDF]

, 2018
Acute Coronary Syndrome (ACS) is a syndrome caused by a decrease in blood flow in the coronary arteries. The ACS is usually related to coronary thrombosis and is primarily caused by plaque rupture followed by plaque erosion and calcified nodule. Thin-cap fibroatheroma (TCFA) is known to be the most similar lesion morphologically to a plaque rupture. In
