Assessment of myocardial contractility during a stress test is of high clinical value for the diagnosis and evaluation of cardiovascular diseases, especially coronary disease and heart failure. Both ends of this left-ventricular mimicking phantom (wall thickness of 15 mm) was then connected to polyvinyl chloride tubing by a pair of loosely attached steel clamps to a pulse duplicator (model #SD2001-1, ViVitro systems Inc., Victoria, BC, Canada). The complex, large, and rapid myocardial deformation during stress tests were also accurately imaged by the proposed strain estimator with close agreement with sonomicrometry.
