Amrute J, Zhang D, Padovano W, Kovacs S
Am J Physiol Heart Circ Physiol
. 2020 Nov;
320(1):H181-H189.
PMID: 33185111
Load, chamber stiffness, and relaxation are the three established determinants of global diastolic function (DF). Coupling of systolic stiffness and isovolumic relaxation has been hypothesized; however, diastolic stiffness-relaxation coupling (DSRC)...

Am J Physiol Heart Circ Physiol
. 2020 Mar;
318(5):H1059-H1067.
PMID: 32142380
The spatiotemporal features of normal in vivo cardiac motion are well established. Longitudinal velocity has become a focus of diastolic function (DF) characterization, particularly the tissue Doppler -wave, manifesting in...

Cardiovasc Eng Technol
. 2018 Jan;
9(1):105-119.
PMID: 29340885
Conventional echocardiographic diastolic function (DF) assessment approximates transmitral flow velocity contours (Doppler E-waves) as triangles, with peak (E), acceleration time (AT), and deceleration time (DT) as indexes. These metrics have...

J Atr Fibrillation
. 2017 May;
6(3):878.
PMID: 28496889
Echocardiographic diastolic function (DF) assessment remains a challenge in atrial fibrillation (AF), because indexes such as E/A cannot be used and because chronic, rate controlled AF causes chamber remodeling. To...

Kohli K, Kovacs S
Physiol Rep
. 2017 Mar;
5(6).
PMID: 28351966
Left ventricular (LV) pressure-volume (-) loop analysis is the gold standard for chamber function assessment. To advance beyond traditional and pressure phase plane (d/dt-P) analysis in the quest for novel...

Maksuti E, Carlsson M, Arheden H, Kovacs S, Broome M, Ugander M
Sci Rep
. 2017 Mar;
7:43505.
PMID: 28256604
Myocardial active relaxation and restoring forces are known determinants of left ventricular (LV) diastolic function. We hypothesize the existence of an additional mechanism involved in LV filling, namely, a hydraulic...

J Atr Fibrillation
. 2016 Dec;
6(6):1018.
PMID: 27957057
Although the electrophysiologic derangement responsible for atrial fibrillation (AF) has been elucidated, how AF remodels the ventricular chamber and affects diastolic function (DF) has not been fully characterized. The previously...

Sci Rep
. 2016 Feb;

PMID: 26915473
The laws of fluid dynamics govern vortex ring formation and precede cardiac development by billions of years, suggesting that diastolic vortex ring formation is instrumental in defining the shape of...

J Magn Reson Imaging
. 2015 Dec;
43(6):1386-97.
PMID: 26663607
Purpose: To present and validate a new method for 4D flow quantification of vortex-ring mixing during early, rapid filling of the left ventricle (LV) as a potential index of diastolic...
