Harmonic power Doppler imaging with intravenous contrast can be a useful modality for identifying and diagnosing abnormal structures within the left ventricle.
May aid LV structure visualization in select cases; hypothesis-generating, with prospective validation needed before wider adoption.
We describe two cases in which echocardiographic image enhancement with an intravenous contrast agent using harmonic power Doppler (HPD) imaging established the diagnosis of abnormal structures in the left ventricle (LV).
