The Variation in the Diastolic Period with Interventricular Septal Displacement and Its Relation to the Right Ventricular Function in Pulmonary Hypertension: A Preliminary Cardiac Magnetic Resonance Study

open access: yesDiagnostics, 2022
Background: Pulmonary hypertension (PH) is known to alter the biventricular shape and temporal phases of the cardiac cycle. The presence of interventricular septal (IVS) displacement has been associated with the severity of PH.

Real-time Assessment of Right and Left Ventricular Volumes and Function in Children Using High Spatiotemporal Resolution Spiral bSSFP with Compressed Sensing [PDF]

open access: yes, 2018
Background: Real-time (RT) assessment of ventricular volumes and function enables data acquisition during free-breathing. However, in children the requirement for high spatiotemporal resolution requires accelerated imaging techniques.

Describing right ventricular function [PDF]

open access: yesEuropean Respiratory Journal, 2013
In pulmonary hypertension and other conditions, such as acute respiratory distress syndrome and left heart failure, right ventricular dysfunction is a prognostic determinant. Therefore, functional parameters pertaining to the right heart alone,i.e.independent of its loading conditions, should be used to quantify right ventricular disease progression ...

The Role of Hand-Held Cardiac Ultrasound in Patients with COVID-19

open access: yesBiomedicines, 2023
The role of point-of-care ultrasound (POCUS) in patient management has been established in recent years as an important tool. It is increasingly used by multiple medical disciplines in numerous clinical settings, for different applications and diagnostic

Estimation of elastic and viscous properties of the left ventricle based on annulus plane harmonic behavior [PDF]

open access: yes, 2006
Assessment of left ventricular (LV) function with an emphasis on contractility has been a challenge in cardiac mechanics during the recent decades. The LV function is usually described by the LV pressurevolume (P-V) diagram. The standard P-V diagrams

Physiological basis in the assessment of myocardial mechanics using speckle-tracking echocardiography 2D. Part I [PDF]

open access: yesJournal of Ultrasonography, 2016
In this paper, the authors attempt to concisely present the anatomical and pathophysiological bases as well as the principles for echocardiographic evaluation of mechanical aspects of cardiac function based on speckle tracking method. This technique uses

Relationship of right ventricular functions with in-hospital and 1 year later mortality in patients hospitalized for COVID-19 pneumonia

open access: yesAnnals of Thoracic Medicine
BACKGROUND: The aim of this study was to determine the association of right ventricular function with in-hospital mortality and mortality 1 year after discharge in patients hospitalized for COVID-19 pneumonia.

FastVentricle: Cardiac Segmentation with ENet

open access: yes, 2017
Cardiac Magnetic Resonance (CMR) imaging is commonly used to assess cardiac structure and function. One disadvantage of CMR is that post-processing of exams is tedious. Without automation, precise assessment of cardiac function via CMR typically requires
