Abstract
Investigation of potential embolic source is an important diagnostic step in treating patients with ischemic stroke and transient ischemic attack. Cardiogenic embolism has been estimated to be the causative factor in 15-30% of all cases of ischemic stroke. Cardioembolic strokes are generally severe and recurrence and mortality rate high. Various cardiac disorders including atrial fibrillation, ventricular thrombus, valvular heart disease, cardiac tumors, and structural heart defects can cause cardioembolic stroke. Although the aortic arch is not a cardiac structure, it is usually considered under source of cardiac embolism (cardioaortic source) and is reviewed in this article. Echocardiography (both transthoracic and transesophageal) is a widely used and versatile technique that can provide comprehensive information of thromboembolic risk in patients with stroke. This article reviews potential cardiac sources of stroke and discusses the role of echocardiography in clinical practice.
