Left ventricular relaxation at rest and during handgrip in aortic valve disease before and after valve replacement [PDF]
, 2017 In 14 patients (pts) with aortic valve disease (A VD) left ventricular (LV) relaxation was assessed by the time constant (T) of LV pressure (tipmanometer) fall before and 19 months after successful aortic valve replacement (A VR).

ESC Heart Failure, Volume 12, Issue 3, Page 2210-2224, June 2025.Abstract Aims Cardiac resynchronization therapy (CRT) improves the prognosis of patients with heart failure (HF) and wide QRS complex. However, patients with non‐left bundle branch block (LBBB) show a poor response to CRT. This study evaluated myocardial work estimated by pressure–strain loops on echocardiography for predicting response to CRT in ...

Seismocardiographic Signal Timing with Myocardial Strain
, 2017 Speckle Tracking Echocardiography (STE) is a relatively new method for cardiac function evaluation. In the current study, STE was used to investigate the timing of heart-induced mostly subaudible (i.e., below the frequency limit of human hearing) chest ...

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 5, May 2025.This review presents the current state‐of‐the‐art in computational modeling of cardiovascular‐induced chest vibrations and offers a practical guide for developing such models. ABSTRACT This paper presents a comprehensive examination of finite element modeling (FEM) approaches for seismocardiography (SCG), a non‐invasive method for assessing cardiac ...

The heart, a secondary organ in the control of blood circulation
Experimental Physiology, Volume 110, Issue 5, Page 649-665, 1 May 2025.Abstract Circulation of the blood is a fundamental physiological function traditionally ascribed to the pressure‐generating function of the heart. However, over the past century the ‘cardiocentric’ view has been challenged by August Krogh, Ernst Starling, Arthur Guyton and others, based on haemodynamic data obtained from isolated heart preparations and

Mitral flow propagation velocity in non-sedated healthy cats
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014 Mitral flow propagation velocity (Vp) is an index used to evaluate the left ventricular diastolic function. Its influence on human and small animal cardiopathies has been studied; however there are few reports evaluating this variable in domestic felines.
