Abstract
The biomechanical integrity of the human heart is critically important, with various diseases affecting the active or passive stiffness of the myocardium. Although manual palpation is an integral part of many diagnostic procedures and is of undisputed clinical value, its applicability is limited to superficial regions. Furthermore, it remains a qualitative not quantitative method. These limits, however, may be overcome with elastography, an exciting new imaging modality that enables noninvasive assessment of biomechanical properties deep inside the body. The general concept is based on the intertwined relationship between the local propagation properties of shear waves and the underlying, intrinsic mechanical shear parameters. Elasticity imaging already has demonstrated very promising results in breast cancer, liver fibrosis staging, and neurodegenerative diseases. However, its application to the cardiovascular system is rather novel, and its challenges include data acquisition and mechanical parameter reconstruction. This article discusses the requirements for performing quantitative elastography of the heart, as well as current developments and future perspectives.

This paper presents initial results in patients with diastolic dysfunction regarding changes in the transmission properties of low-frequency waves. Although of potential diagnostic value, it remains to be understood whether those changes reflect changes in the shear properties of the myocardium.

Kolipaka A et al. Magnetic resonance elastography as a method to estimate myocardial contractility. J Magn Reson Imaging JMRI. 2012;36:120–7. This study investigated the influence of geometric boundary conditions and sought limits for the proposed stiffness calculation method. A finite element modeling analysis revealed significant biases in the stiffness estimate when the ratio of wavelength to wall thickness exceeded 2.5. Here, the increase of effective end-systolic stiffness was correlated with the increase in heart rate by epinephrine infusion in a pig model. A good linear correlation was found for the individual measurements, with R 2 values ranging from 0.86 to 0.99 in four pigs.

This paper describes the real-time capabilities of ultrafast ultrasound-based elastography and its application to the cardiovascular domain. Although typically limited to encoding only one or two displacement directions, this method allows fascinating in vivo applications because of an unmatched frame rate of up to 4500 images per second.
