Table 2.
Echocardiographic findings according to high and low/uncertain embolic risk.
| TTE findings (n) | TEE findings (n) | |
|---|---|---|
| High embolic risk | ||
| Left atrial (appendage) thrombus | 0 | 1 |
| Valve vegetation | 0 | 1 |
| Aortic atherosclerotic plaques | 0 | 2 |
| Structure at mitral valve | 1 | 2 |
| Low/uncertain embolic risk | ||
| PFO †* | 1 | 10 |
| ASA †* | 2 | 7 |
| Spontaneous echo contrast | 0 | 1 |
| Mitral valve prolaps | 4 | 4 |
| Thickening of the mitral valve | 1 | 1 |
† p<0.05. There were no significant differences for the other findings. *Injection of agitated saline during TTE was only performed during the last years of this study. In 59 patients TTE and TEE did not reveal a potential CES. PFO=patent foramen ovale, ASA=atrial septal aneurysm.
