Rendimiento diagnóstico del estudio ecocardiográfico en el accidente cerebrovascular: ¿debemos mejorar la selección de los pacientes?

We found major echocardiographic criteria in 6 patients (5%) with embolic stroke and in 2 (0.7%) non embolic, P = .005. In view of our results, the performance of transthoracic echocardiography in patients with embolic stroke has a low diagnostic yield, which leads us to question systematic use of this technique.
