Patent foramen ovale (PFO) has been identified as a source of paradoxical embolism and cryptogenic stroke.1 Percutaneous PFO closure seems to be a highly efficient and safe procedure for the prevention of interatrial shunting,2 and is intended to reduce the recurrence of paradoxical emboli and cryptogenic stroke. Implantable PFO occluders of different types are of variably-sized (20–35 mm diameter) metal-containing devices. It is not clear whether implantation of these devices in the interatrial septum affects the motion of the nearby structures and biomechanics of the heart. Doppler tissue imaging (DTI) allows for the quantitative assessment of regional myocardial tissue velocities. We prospectively evaluated DTI parameters before and after percutaneous PFO closure in patients with an otherwise structurally normal heart.
