ABSTRACT

Cardioembolic stroke is the most disabling cause of stroke and accounts for 30% of ischemic strokes (1, 2). The diagnosis is based on the identification of a potential cardiac source of embolism (SOE) (3). Transthoracic Echocardiogram (TTE) is a non-invasive, available and easy to perform technique to detect SOE with potential therapeutic implications (4, 5). The therapeutic yield of the TTE ranges from 2 to 37.2% depending on the age of the patients and previous heart disease (6, 7). A normal TTE decreases the yield of other advances techniques to detect SOE such as transesophageal echocardiogram (TEE) (8). TTE has been increasingly performed as part of stroke workup in the past few years, whereas TEE is used infrequently as screening test (9). More recently, Point of Care UltraSound (POCUS) concept has increased its field of application and TTE as a screening method at the Stroke Unit is certainly under this rationale (10).
