Figure 2

Transthoracic echocardiogram showing left ventricle long and short axis views after iloprost nebulization. In the echocardiographic evaluation after iloprost administration we can detect a reduction in right ventricular dimension, with a proportional increase in left ventricular dimension and performance. The correction of the septal shift secondary to right ventricular overload also contributes to a smaller right ventricle and expanded left ventricle.
