Aortic valve disorders and left ventricular assist devices

Frontiers in Cardiovascular Medicine, 2023
Aortic valve disorders are important considerations in advanced heart failure patients being evaluated for left ventricular assist devices (LVAD) and those on LVAD support. Aortic insufficiency (AI) can be present prior to LVAD implantation or develop de

Comparison of aortic media changes in patients with bicuspid aortic valve stenosis versus bicuspid valve insufficiency and proximal aortic aneurysm.

Interactive Cardiovascular and Thoracic Surgery, 2013
OBJECTIVES The aim of this study was to evaluate aortic media changes in bicuspid aortic valve (BAV) patients who underwent aortic valve replacement (AVR) and simultaneous replacement of the proximal aorta for BAV stenosis vs BAV insufficiency ...

Quadricuspid aortic valve; a rare cause of aortic insufficiency

Case Reports, 2008
An asymptomatic 32-year-old Afro-Caribbean gentleman underwent transthoracic echocardiography after a routine cardiovascular examination identified an early diastolic murmur. Severe aortic insufficiency in the background of a quadricuspid aortic valve was seen on the echocardiography (figs 1 and 2; videos 1 and 2). All …

ProtoASNet: Dynamic Prototypes for Inherently Interpretable and Uncertainty-Aware Aortic Stenosis Classification in Echocardiography [PDF]

arXiv, 2023
Aortic stenosis (AS) is a common heart valve disease that requires accurate and timely diagnosis for appropriate treatment. Most current automatic AS severity detection methods rely on black-box models with a low level of trustworthiness, which hinders clinical adoption. To address this issue, we propose ProtoASNet, a prototypical network that directly

Free‐breathing accelerated whole‐body MRI using an automated workflow: Comparison with conventional breath‐hold sequences

NMR in Biomedicine, Volume 36, Issue 2, February 2023., 2023
Free‐breathing whole‐body MRI in tandem with an automated user interface yielded similar diagnostic accuracy at equivalent image quality and shorter acquisition times compared with breath‐hold MR sequences. Scores for patient satisfaction were significantly better for free‐breathing compared with breath‐hold examinations, including significant ...

A deep learning approach to using wearable seismocardiography (SCG) for diagnosing aortic valve stenosis and predicting aortic hemodynamics obtained by 4D flow MRI [PDF]

arXiv, 2023
In this paper, we explored the use of deep learning for the prediction of aortic flow metrics obtained using 4D flow MRI using wearable seismocardiography (SCG) devices. 4D flow MRI provides a comprehensive assessment of cardiovascular hemodynamics, but it is costly and time-consuming.

Quadricuspid aortic valve associated with aortic insufficiency contributors

Annals of Cardiac Anaesthesia, 2019
A 51-year-old male presented with a wound in his right hand that was suspicious for possible septic emboli of cardiac origin. With transesophageal echocardiography, the patient was found to have a rare quadricuspid aortic valve. This quadricuspid valve can present with variable symptoms and physical exam findings.
