State-of-the-art cardiac imaging makes it possible to assess myocardial function at a level of detail not seen before.
Measurements of left ventricular (LV) work, efficiency, stiffness and contractility from pressure-volume (PV) loops is the gold standard for assessing left ventricular (LV) function. However, use is limited because of the need for invasive left ventricular catheterization. Through advances in cardiac imaging it has become possible to measure these functional aspects non-invasively. In addition, state-of-the-art imaging technology can directly assess regional differences in myocardial function. This makes it possible to go beyond the measurements of global chamber function, as is done with PV loops, and assess myocardial function at a level of detail not seen before.
