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.

Acute Mitral Regurgitation Secondary to Spontaneous Left Atrial Appendage Occluder Migration.

A patient underwent left atrial appendage occlusion due to recurrent stroke despite new oral anticoagulant therapy. The patient later presented with severe acute mitral regurgitation secondary to occluder device migration, which was retrieved percutaneously from the descending aorta via the femoral artery. Mitral surgical repair was required and successfully performed.
