Feasibility of Bidimensional Speckle-Tracking Echocardiography for Strain Analysis in Consecutive Patients in Daily Clinical Practice.
Summary of "Feasibility of Bidimensional Speckle-Tracking Echocardiography for Strain Analysis in Consecutive Patients in Daily Clinical Practice."
Purpose: We aimed to analyze the feasibility of two-dimensional speckle-tracking echocardiography (2DSTE) in evaluating myocardial strain in consecutive, nonselected patients in daily clinical practice. Methods: Strain analysis using 2DSTE was attempted in 59 consecutive patients: 24 patients with severe aortic stenosis, 28 patients with dilated cardiomyopathy, and 7 healthy controls. The analysis was done by four expert echocardiographers and one cardiology resident. Results: It was possible to obtain reliable data for radial strain in 175 of 354 segments (49%), circumferential strain in 192 of 354 segments (54%), and longitudinal strain in 319 of 354 segments (90%). Experienced echocardiographers felt assessment of radial and circumferential strain was appropriate in more segments than did the cardiology resident (57% and 58% vs. 23% and 40%, respectively, P < 0.01). Conclusion: Longitudinal strain analysis with 2DSTE is feasible in most segments, but the radial and circumferential strain evaluation was only feasible in approximately half of the patients.

Medical and Biotech [MESH] Definitions
Echocardiography, Three-dimensional
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
Echocardiography, Doppler, Color
Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
Echocardiography, Four-dimensional
Dynamic three-dimensional echocardiography using the added dimension of time to impart the cinematic perception of motion. (Mayo Clin Proc 1993;68:221-40)
Echocardiography, Doppler, Pulsed
Echocardiography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
Feasibility Studies
Studies to determine the advantages or disadvantages, practicability, or capability of accomplishing a projected plan, study, or project.
