Sensitivity of transcranial doppler and transoesophageal echocardiography for the detection of patent foramen ovale in cryptogenic stroke
Conclusions TCD with bubble test is sensitive and specific for the detection of right–to–left shunts due to PFO confirmed at right heart catheterisation. In this population, TOE had low sensitivity for RLS. There was no difference in physical PFO size between TOE positive and negative patients.

Platypnoea orthodeoxia syndrome and its association with cryptogenic ischaemic stroke
J R Coll Physicians Edinb. 2023 Mar 4:14782715231159470. doi: 10.1177/14782715231159470. Online ahead of print.ABSTRACTPlatypnoea orthodeoxia syndrome is a rare condition, which can be present in patients with patent foramen ovale (PFO). In this case, a 72-year-old lady presented to the emergency department with a cryptogenic stroke associated with right thalamic infarct. While in hospital, it was noticed that the patient had desaturations in the upright position, and these improved in the recumbent position, consistent with platypnoea orthodeoxia syndrome. The patient was found to have a PFO, which was then closed, and he...
