Patent Foramen Ovale and Stroke in Intermediate-Risk Pulmonary Embolism

PFO and related ischemic strokes are frequent in intermediate-risk PE. TEE is much more efficient than TTE for PFO diagnosis. Considering the high risk of intracranial bleeding with thrombolysis in PE, which may be partly due to hemorrhagic transformation of subclinical strokes, screening PFO with TEE should be considered in intermediate-risk PE when thrombolytic treatment is discussed.
