Conclusion Our 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

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.
