[Systematic implementation of transthoracic echocardiography, transesophageal echocardiography and 24-hour Holter ECG for the detection of cardiac sources of embolism in patients with stroke or transient ischemic attack. A retrospective study of 220 patients].

Introduction: Embolism of cardiac origin accounts for around 20% of ischemic strokes. ECG and transthoracic echocardiography (TTE) are commonly obtained during the evaluation of patient of ischemic stroke but specific indications for the transesophageal (TEE) echocardiography and 24-hour Holter ECG (Holter) remain uncertain.

Objectives: The aim of this study is to report the contribution of TTE, TEE and Holter performed as a routine during the evaluation of patients with ischemic stroke (IS) or transient ischemic attack (TIA).
