Implementation and Calibration of a Deep Neural Network to Predict Parameters of Left Ventricular Systolic Function Based on Pulmonary and Systemic Arterial Pressure Signals

“…The former permit the determination of ventricular end-systolic elastance (Ees), a load-independent measurement of ventricular contractility (Burkhoff et al, 2005 ; Naeije and Manes, 2014 ). Nowadays these measurements require invasive techniques only available in the catheterization laboratory (Bonnet et al, 2017 ). Non-invasive methods have been developed, including magnetic resonance imaging (Bastos et al, 2019 ), or real-time three dimensional echocardiography (Seemann et al, 2019 ), but these cannot be easily implemented in the daily clinical practice.…”

Evaluation of patients with high burden of premature ventricular contractions by comprehensive transthoracic echocardiography

“…Ventricular end-systolic elastance is an echocardiographic parameter associated with both systolic and diastolic performance [56] , [57] and can be described as the relation between pressure and volume inside the left ventricle. In our study elastance was significantly lower amongst PVC-patients, possibly summarising their combined systolic and diastolic impairment.…”

Deep Neural Network to Accurately Predict Left Ventricular Systolic Function Under Mechanical Assistance

“…The determination of E max,lv is challenging, requiring left-side heart chambers catheterization, a technique whose implementation is not realistic in the daily clinical practice. Non-invasive methods, including echocardiography and magnetic resonance imaging, coupled to measurement of arterial blood pressure have been proposed ( 24 , 25 ), however their use is mainly restricted to the experimental setting. Furthermore, none of these techniques have so far been applied to assess E max,lv in patients assisted with a LVAD.…”
