Right Ventricular Postsystolic Strain Curve Morphology before and after Vasodilator Treatment in Idiopathic Pulmonary Arterial Hypertension.

• RV function is an important prognostic factor in pulmonary arterial hypertension. • Several echocardiographic parameters are needed for a complete RV function assessment. • RV postsystolic strain patterns have a prognostic impact in IPAH.

We report the case of a patient with non-responding SLS (neither to glucocorticoids nor immunosupresors), who showed remarkable improvement after the onset of treatment with rituximab. Although there is a little evidence, treatment with rituximab could be proposed in SLS when classical treatment fails.
