Aims Assessment of right ventricular (RV) function in acute pulmonary embolism (PE) has prognostic significance. The aim of this study was to evaluate right atrium (RA) and RV myocardial damage with 2-dimensional speckle-tracking in patients with an acute central vs an acute peripheral PE. Methods and Results Twenty-six patients with acute PE and 10 controls were retrospectively enrolled. Right atrium and RV myocardial deformation was analyzed using speckle-tracking imaging echocardiography. Parameters were evaluated to illustrate myocardial damage in patients with a central or a peripherally located PE. Thirteen of the enrolled patients had a massive central PE, and thirteen subjects had a peripheral located PE. Baseline characteristics were not significantly different between the 3 groups besides a more elevated heart rate among patients with a central PE (P = .02) and a tendency of an increased D-dimer in this group. Right ventricular dimensions were more affected among patients with a PE. Compared with controls, segmental RV and RA strain/strain rate in the free wall was significantly reduced in patients with PE (P < .05). No difference was shown between the 2 groups of PE. Conclusion This pilot study suggests that basal-/mid-segments of RA and RV free wall are more affected in patients with a PE compared with controls. Interestingly, we found no significant difference in myocardial RA and RV damage between patients with a central and a peripheral PE. We advocate that PE no matter central or peripheral is a serious condition and that a peripheral PE has to be intensively treated similar to a central PE.
