Type X dual left anterior descending (LAD) artery masquerading as type 1 LAD — a case report

The Egyptian Journal of Internal Medicine, 2021
Background Dual left anterior descending (LAD) coronary artery is a rare congenital anomaly. To date, eleven variants of dual LAD have been described with three published reports of type X dual LAD. Here, we describe a new variant of type X dual LAD with

MPSeg : Multi-Phase strategy for coronary artery Segmentation [PDF]

arXiv, 2023
Accurate segmentation of coronary arteries is a pivotal process in assessing cardiovascular diseases. However, the intricate structure of the cardiovascular system presents significant challenges for automatic segmentation, especially when utilizing methodologies like the SYNTAX Score, which relies extensively on detailed structural information for ...

Endothelial damage and complement dysregulation in fetuses from pregnancies complicated by preeclampsia

Acta Obstetricia et Gynecologica Scandinavica, Volume 104, Issue 5, Page 829-838, May 2025.
Preeclampsia fetuses show an altered profile of endothelial damage and complement biomarkers, like increased adhesion molecules, prothrombotic state, oxidative stress, and reduced complement membrane attack complex deposition on endothelial cells. Abstract Introduction Our objective was to evaluate the endothelial function profile and complement system

Blood Vessel Geometry Synthesis using Generative Adversarial Networks [PDF]

arXiv, 2018
Computationally synthesized blood vessels can be used for training and evaluation of medical image analysis applications. We propose a deep generative model to synthesize blood vessel geometries, with an application to coronary arteries in cardiac CT angiography (CCTA).

Robust Implementation of Foreground Extraction and Vessel Segmentation for X-ray Coronary Angiography Image Sequence [PDF]

arXiv, 2022
The extraction of contrast-filled vessels from X-ray coronary angiography (XCA) image sequence has important clinical significance for intuitively diagnosis and therapy. In this study, the XCA image sequence is regarded as a 3D tensor input, the vessel layer is regarded as a sparse tensor, and the background layer is regarded as a low-rank tensor ...

A Beating‐Heart Procedure with Soft Robotic Guidance

Advanced Robotics Research, Volume 1, Issue 1, April 2025.
Robot‐assisted pacemaker lead placement through the coronary sinus enabled cardiac pacing in multiple in vivo studies. When compared with conventional clinical tools, the robot reduced procedural time, duration of harmful radiation exposure, and the possibility of tissue damage.

Reducing the X-ray radiation exposure frequency in cardio-angiography via deep-learning based video interpolation [PDF]

arXiv, 2020
Cardiac coronary angiography is a major technology to assist doctors during cardiac interventional surgeries. Under the exposure of X-ray radiation, doctors inject contrast agents through catheters to determine the position and status of coronary vessels in real time.

Identification of dilated cardiomyopathy‐linked key genes by bioinformatics methods and evaluating the impact of tannic acid and monosodium glutamate in rats

Biotechnology and Applied Biochemistry, Volume 72, Issue 2, Page 377-387, April 2025.
Abstract Dilated cardiomyopathy (DCM) is the most common type of myocardial dysfunction, affecting mostly young adults, but its therapeutic diagnosis and biomarkers for prognosis are lacking. This study aimed to investigate the possible effect of the common food additive monosodium glutamate (MSG) and tannic acid (TA), a phenolic compound, on the key ...
