[Stroke and Takotsubo syndrome: a reciprocal relationship].

Introduction: Takotsubo syndrome is a transient stress cardiomyopathy associated with a distinctive left ventricular contraction pattern. It has been described as a cardioembolic source or as a consequence of stroke. Two patients are reported that illustrate the reciprocal relationship between Takotsubo syndrome and stroke and the physiopathological mechanisms implicated are analyzed.

Comparison of gadofosveset-enhanced three-dimensional magnetic resonance angiography with digital subtraction angiography for lower-extremity peripheral arterial occlusive disease.

Background: Minimally invasive imaging techniques are increasingly used for clinical decision making in patients with peripheral arterial occlusive disease (PAOD).

Purpose: To assess whether gadofosveset-enhanced three-dimensional (3D) magnetic resonance (MR) angiography could replace digital subtraction angiography (DSA) for the evaluation of lower-extremity PAOD.

Material And Methods: Thirty patients with symptomatic PAOD underwent prospectively both MR angiography and DSA.
