[Initial experience with the use of Levovist in adult patients with suboptimal echocardiograms].

Objective: To report our experience with the use of Levovist in echocardiographic studies.

Method: We studied consecutively patients with suboptimal echocardiographic studies. A bolus of 4 gr @ 400 mg/ml was administered via antecubital vein and a second echocardiogram was performed during the ensuing minutes.
