Figure 1
Figure 1
Right ventricular fractional area change (RVFAC) estimation in (A) a 73-year old male with ischemic cardiomyopathy who has become inotrope dependent in the past few months and (B) a 43-year old female with nonischemic cardiomyopathy awaiting heart transplantation who required an intra-aortic balloon pump for stabilization. Both patients received a Heart Mate II device 10 days later as destination therapy and bridge-to-transplant, respectively. Patient A was weaned from inotropes on postoperative day 5, whereas patient B required inotropic support for 38 days. Note the heavy trabeculation and the strong echo from the defibrillator lead in B.

Figure 2
Tricuspid annular systolic plane excursion (TAPSE) in the same patients as in Figure 1. Patient A exhibits a very low TAPSE (0.7 cm), indicative of severe RV dysfunction, despite the mildly abnormal RVFAC. In contrast, patient B has a low-normal TAPSE (1.6 cm) despite severely depressed RVFAC. However, as evident from the elevated heart rate (105 bpm), patient B is in hemodynamic stress, which is accompanied by exaggerated translational motion of the heart, thus overestimating TAPSE. The use of color M-mode, although not necessary for TAPSE estimation, facilitates detection of directional changes in motion.

Figure 3
Tricuspid annular systolic velocity (S’) by tissue Doppler imaging in the same patients as in Figure 1. Similar to tricuspid annular systolic plane excursion (TAPSE), longitudinal velocities are depended on load, translational motion, and insonation angle. Patient A exhibits abnormal S’ (<10 cm/s), whereas patient B has a low-normal S’ (11 cm/s), despite discordant RVFAC results.
Figure 4
Figure 4
Right ventricular (RV) longitudinal strain by speckle tracking in the same patients as in Figure 1. In patient A (ischemic etiology), the interventricular septum demonstrates very low peak strain (normal values: −14±4% to −22±5% from base to apex) suggestive of severe systolic dysfunction, whereas the RV free wall demonstrates preserved systolic function, especially at the basal and mid segments (lower reference values: −18% to −20%)., In patient B (nonischemic etiology), the very low peak strain values across all segments and the very low global strain (−4.3%) suggest severe global RV systolic dysfunction. Note also the fragmented systolic activation in the linearized map (lower left panel) in patient B as compared to the more homogenous activation in patient A.
