TL;DR: A case in which the combination of gray scale imaging of wall thickness changes allied to color DMI regional velocity, strain, and strain rate data identified the development and regression of diastolic thickening in the acute ischemic segment during a right coronary artery percutaneous transluminal coronary angioplasty (PTCA).

Abstract: We report a case in which the combination of gray scale imaging of wall thickness changes allied to color DMI regional velocity, strain, and strain rate data identified the development and regression of diastolic thickening in the acute ischemic segment during a right coronary artery percutaneous transluminal coronary angioplasty (PTCA). We also discuss the possible mechanisms and potential clinical implications of this finding. (J Am Soc Echocardiogr 1999;12:994-6.)

Assessment of segmental myocardial viability using regional 2-dimensional strain echocardiography.
Raymond Q. Migrino,Xiaoguang Zhu,Nicholas M. Pajewski,Tejas Brahmbhatt,Raymond G. Hoffmann,Ming Zhao +5 more
TL;DR: Two-dimensional strain echocardiography-derived strain is useful in distinguishing infarcted from viable myocardium in a rat ischemia-reperfusion model and correlates with radial and circumferential strain.
Doppler tissue velocity, strain, and strain rate imaging with transesophageal echocardiography in the operating room: A feasibility study
L Simmons,Frank Weidemann,George R. Sutherland,Jan D'hooge,Bart Bijnens,Paul Sergeant,Patrick Wouters +6 more
TL;DR: DMI with TEE is feasible during cardiac operation but requires further evaluation in the assessment of ventricular function and the detection of ischemia in the operating room.
Real-time strain rate echocardiographic imaging: temporal and spatial analysis of postsystolic compression in acutely ischemic myocardium.
TL;DR: The temporal and spatial analysis of T-CEC with the use of strain rate imaging is a new noninvasive technique for identification and topographic quantitation of ischemic diastolic dysfunction expressed by PSC.
Noninvasive quantification of regional myocardial function using Doppler-derived velocity, displacement, strain rate, and strain in healthy volunteers: effects of aging
Jing Ping Sun,Zoran B. Popović,Neil L. Greenberg,Xiao Fang Xu,Craig R. Asher,William J. Stewart,James D. Thomas +6 more
TL;DR: Although myocardial velocities and strain rate showed significant dependence on age, displacement and peak systolic strain measures were less affected, and Doppler tissue echocardiography measurements showed a strong dependence on wall segment position.
Conversion of post-systolic wall thickening into ejectional thickening by selective heart rate reduction during myocardial stunning
Laurence Lucats,Bijan Ghaleh,Xavier Monnet,Xavier Monnet,Xavier Monnet,Patrice Colin,Patrice Colin,Patrice Colin,Alain Bizé,Alain Bizé,Alain Bizé,Alain Berdeaux +11 more
TL;DR: Selective heart rate reduction with ivabradine converts PSWT into ejectional thickening but not with atenolol secondary to its negative inotropism.

The effect of coronary occlusion on myocardial contraction
Robert Tennant,Carl J. Wiggers +1 more
TL;DR: Desc descriptions of a technique and of a type of optical myograph suitable for such studies and an analysis of the changes in optical myograms which follow clamping of a large coronary vessel are concerned.

Real-time strain rate imaging of the left ventricle by ultrasound
TL;DR: In the healthy hearts, a spatially homogeneous distribution of the strain rate was found and all the infarcted areas in this study showed up as hypokinetic or akinetic, demonstrating that this method may be used for imaging of regional dysfunction.

Quantitative Assessment of Alterations in Regional Left Ventricular Contractility With Color-Coded Tissue Doppler Echocardiography Comparison With Sonomicrometry and Pressure-Volume Relations
TL;DR: TDI measures reflect directional and incremental alterations in regional and global LV contractility and have the potential to quantify regional LV function.

Analysis of systolic bulging. Mechanical characteristics of acutely ischemic myocardium in the conscious dog.
TL;DR: It is concluded that systolic bulging depends on the change in the preload tension due to the compliant portion of tension-length curve, and that shortening of ischemic myocardium during the isovolumic relaxation phase is a completely passive phenomenon.

Transmural myocardial deformation in the ischemic canine left ventricle.
TL;DR: The results indicate that after 5 minutes of acute ischemia, end-systolic in-plane lengthening across the left ventricular wall occurs in approximately equal amounts in the circumferential and longitudinal directions, which indicates that uniaxial measurements of deformation in the ischemic myocardium are incomplete and must be interpreted with caution.
