Abstract

Objectives: Right ventricular (RV) failure post left ventricular assist device (LVAD) implantation is associated with increased morbidity and mortality. A novel RV multi-plane imaging method using two-dimensional echocardiography and electronic plane rotation (MPE) was used to quantify RV function prior to LVAD implantation and to identify potential added value in this patient population. Methods: In twenty-five end-stage heart failure patients (age 58.9 ± 6.8 years, 76% male), systolic function of four different RV walls (lateral, anterior, inferior and inferior coronal) were evaluated from one focussed apical view using MPE. Results: Feasibility of tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular peak systolic velocity (RV-S') measurements were high (84–100%), with lower TAPSE values measured in the inferior (14.2 ± 4.6 mm) and inferior coronal (12.3 ± 5.0 mm) walls compared to the lateral (16.3 ± 4.5 mm) and anterior walls (16.0 ± 4.5 mm). RV wall longitudinal strain (RV-LS) measurement was most feasible in the lateral wall (80%; mean: –12.1 ± 4.2%). TAPSE and RV-LS values were significantly reduced in patients compared to matched healthy individuals (p = <0.001). Seven (28%) patients who developed moderate to severe RV failure (RVF) early post-implant (≤30 days) had lower pre-implant values across all multi-plane parameters compared to those without significant post-implant RVF, notably four-wall averaged TAPSE (11.1 ± 3.4 mm vs 15.9 ± 4.0 mm; p = 0.02). Conclusion: 2D MPE was highly feasible for RV wall quantification pre-LVAD surgery, detecting differences in regional wall function. This novel method comprehensively quantifies RV wall function and could complement current pre-LVAD screening protocols.
