Abstract
Aims Both contrast enhanced (CE) two-dimensional echocardiography (2DE) and three-dimensional echocardiography
(3DE) have been proposed as techniques to improve the accuracy of left ventricular (LV) volume measurements.
We sought to examine the accuracy of non-contrast (NC) and CE-2DE and 3DE for calculation of LV volumes
and ejection fraction (EF), relative to cardiac magnetic resonance imaging (MRI).
Methods and results We studied 50 patients (46 men, age 63±10 year) with past myocardial infarction who underwent echocardiographic assessment of LV volume and function. All patients sequentially underwent NC-2DE followed by NC-3DE. CE-2DE and CE-3DE were acquired during contrast infusion. Resting echocardiographic image quality was evaluated on the basis of NC-2DE. The mean LV end-diastolic volume (LVEDV) of the group by MRI was 207±79 mL and was underestimated by 2DE (125±54 mL, P = 0.005), and less by CE-2DE (172±58 mL, P = 0.02) or 3DE (177±64 mL, P = 0.08), but EDV was comparable by CE-3DE (196±69 mL, P = 0.16). Limits of agreement with MRI were similar for NC-3DE and CE-2DE, with the best results for CE-3D. Results were similar for calculation of LVESV. Patients were categorized into groups of EF (≤35, 35–50, .50%) by MRI. NC-2DE demonstrated a 68% agreement (kappa 0.45, P = 0.001), CE-2DE a 62% agreement (kappa 0.20, P = 136), NC-3DE a 74% agreement (kappa 0.39, P = 0.005) and CE-3DE an 80% agreement (kappa 0.56, P < 0.001).
Conclusion CE-2DE is analogous to NC-3DE in accurate categorization of LV function. However, CE-3DE is feasible and superior to other NC- and CE-techniques in patients with previous infarction.
