Prognostic role of CMR in patients presenting with ventricular arrhythmias.

Objectives: The goal of this study was to explore whether fibrosis detected by late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) is an independent predictor of hard cardiovascular events in patients presenting with ventricular arrhythmia.

Background: In patients at risk of sudden cardiac death, risk stratification for device therapy remains challenging.

Methods: A total of 373 consecutive patients with sustained ventricular tachycardia (VT) (n = 204) or nonsustained ventricular tachycardia (NSVT) (n = 169) underwent LGE-CMR.

An unusual cause of acute limb ischemia: aortic intimal sarcoma.

Acute limb ischemia, a serious medical condition characterized by a rapid decrease in limb perfusion, often threatens limb viability. Acute limb ischemia can be secondary to multitude of causes, with the two most common being embolus and thrombosis in situ secondary to underlying peripheral artery disease. In this report we present an unusual case of acute limb ischemia secondary to intimal sarcoma of the thoracic aorta and outline the role of cardiovascular magnetic resonance imaging in such cases.
