Automatic Time‐Resolved Cardiovascular Segmentation of 4D Flow MRI Using Deep Learning

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 191-203, January 2023., 2023
Background Segmenting the whole heart over the cardiac cycle in 4D flow MRI is a challenging and time‐consuming process, as there is considerable motion and limited contrast between blood and tissue. Purpose To develop and evaluate a deep learning‐based segmentation method to automatically segment the cardiac chambers and great thoracic vessels from 4D

Frailty Assessment in Aortic Stenosis based on Dynamic Interconnection between Cardiac and Motor Systems [PDF]

arXiv
Background: Aortic stenosis (AS) is the most common acquired valvar disease and is associated with increased risk for frailty. Frailty as a geriatric syndrome is associated with muscle weakness and a compromised autonomic nervous system (ANS) performance in older adults.

Global Aortic Pulse Wave Velocity is Unchanged in Bicuspid Aortopathy With Normal Valve Function but Elevated in Patients With Aortic Valve Stenosis: Insights From a 4D Flow MRI Study of 597 Subjects

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 126-136, January 2023., 2023
Background Aortopathy is common with bicuspid aortic valve (BAV), and underlying intrinsic tissue abnormalities are believed causative. Valve‐mediated hemodynamics are altered in BAV and may contribute to aortopathy and its progression. The contribution of intrinsic tissue defects versus altered hemodynamics to aortopathy progression is not known ...

Reliable Multi-View Learning with Conformal Prediction for Aortic Stenosis Classification in Echocardiography [PDF]

arXiv
The fundamental problem with ultrasound-guided diagnosis is that the acquired images are often 2-D cross-sections of a 3-D anatomy, potentially missing important anatomical details. This limitation leads to challenges in ultrasound echocardiography, such as poor visualization of heart valves or foreshortening of ventricles.

Cor Triatriatum in the Adult with Aortic Stenosis and Mitral Stenosis [PDF]

, 2018
Background：Cor triatriatum is a rare congenital cardiac anomaly, in which the left atrium or right atrium is separated by an abnormal fibromuscular membrane with one or more restrictive orifices.
