Myocardial contrast echocardiography. Echocardiographic contrast is injected into a chosen septal artery with continuous echocardiographic screening. Localisation of the contrast can be observed in the basal septum in the parasternal long-axis (A), apical 5-chamber (B) and apical long-axis (C) views. (D) A parasternal short-axis view with contrast visible at 11 O'clock. This is required as an additional view to ensure that the chosen vessel does not supply an area too inferior or anterior in the septum. Contrast should highlight the SAM–septal contact area.
