Gradient Boosting on Decision Trees for Mortality Prediction in Transcatheter Aortic Valve Implantation [PDF]
arXiv, 2020 Current prognostic risk scores in cardiac surgery are based on statistics and do not yet benefit from machine learning. Statistical predictors are not robust enough to correctly identify patients who would benefit from Transcatheter Aortic Valve Implantation (TAVI).

Automatic Aortic Valve Pathology Detection from 3-Chamber Cine MRI with Spatio-Temporal Attention Maps [PDF]
arXiv, 2023 The assessment of aortic valve pathology using magnetic resonance imaging (MRI) typically relies on blood velocity estimates acquired using phase contrast (PC) MRI. However, abnormalities in blood flow through the aortic valve often manifest by the dephasing of blood signal in gated balanced steady-state free precession (bSSFP) scans (Cine MRI).

Immersed boundary model of aortic heart valve dynamics with physiological driving and loading conditions [PDF]
Int J Numer Meth Biomed Eng, 28(3):317-345, 2012, 2017 The immersed boundary (IB) method is a mathematical and numerical framework for problems of fluid-structure interaction, treating the particular case in which an elastic structure is immersed in a viscous incompressible fluid. The IB approach to such problems is to describe the elasticity of the immersed structure in Lagrangian form, and to describe ...

TAVI nel trattamento della stenosi aortica degenerativa: stato dell’arte e prospettive [PDF]
, 2014 Degenerative aortic stenosis is the most common form of heart valve disease in developed countries and predominantly affects the elderly. Aortic valve replacement (AVR) has been the gold standard, but recently, transcatheter aortic valve implantation has

CT in Transcatheter Aortic Valve Replacement [PDF]
Radiology, 2013 Transcatheter aortic valve replacement is a new method to treat patients with symptomatic, severe aortic stenosis who are at high surgical risk. Short- and midterm results have been encouraging, with more than 90,000 procedures performed worldwide. Patient selection, prosthesis sizing, and access strategies heavily rely on noninvasive imaging. Computed
