15 Improvement in diagnosis of ischaemic cardiomyopathy by cardiovascular magnetic resonance

Abstract

ConclusionOur results are concordant with previous studies demonstrating that diagnostic accuracy of hTTE is heavily influenced by operator experience. It is less known how much training should be given to operators before hTTE assessment is reliable enough to base clinical decisions upon. However with simple education, we hope to demonstrate that discrepancy between hTTE and sTTE can be reduced. Moving forwards, we plan to introduce a dedicated training day for new ST3 cardiology trainees and observe how this influences performance. The discrepancy and underestimation with hTTE raises the question of clinical implications, particularly of underestimating MR. It may be the case that cardiology trainees should be more prudent when commenting on MR, spend slightly longer obtaining images if MR is present and liaise more closely with medical colleagues informing them about the limitations of HHE.Abstract 14 Figure 2 Graph demonstrating the proportion of underestimation and overestimation in discordant scans across each parameter Abstract 14 Table 1 Severity grading system used to assess left ventricular systolic function (LVSF), mitral regurgitation (MR), aortic regurgitation (AR) and aortic stenosis (AS) Abstract 14 Table 2 Table showing average error for each parameter pre-and post-intervention with respective weighted kappa statistics (κ) Kappa values of <0.2 were interpreted as poor, 0.21-0.4 as fair, 0.41-0.6 as moderate, 0.61-0.8 as good, and 0.Abstract 15 Figure 1 Case 1-severe disease in mid LAD (arrow) on invasive angiography (A) but no ischaemid scar on LGE imaging (B & C)
