This white paper reviews the role of left ventricular strain imaging in cardiomyopathy, comparing Samsung’s Strain+ on the cV7 ultrasound system with the established TomTec software. The study was designed to determine whether Strain+ provides results consistent with TomTec in measuring global longitudinal strain (GLS), a critical parameter for detecting early myocardial dysfunction.
A set of cardiomyopathy patient echocardiograms was analyzed side by side. The findings showed strong agreement between Strain+ and TomTec across multiple chamber views, with differences remaining within clinically acceptable limits. This validates Strain+ as a reliable tool for cardiac function assessment in patients with diverse cardiomyopathies.
The paper also highlights clinical case examples to demonstrate the practical value of GLS assessment. These include patients with pacing differences, where strain analysis captured functional variation; cardiac amyloidosis, where GLS patterns helped reveal typical disease markers; and myocarditis, where strain reduction was evident in inflamed myocardium.
The study concludes that Samsung’s Strain+ LV strain imaging on cV7 delivers reproducible GLS values comparable to TomTec. This supports its application in cardiomyopathy diagnosis, disease monitoring, and treatment planning. While the evaluation was limited to one center and a single reviewer, the results confirm Strain+ as a clinically valuable feature that enhances the diagnostic scope of echocardiography.
