Patent Foramen Ovale: Pivotal Role of Transesophageal Echocardiography in the Indications for Closure, Assessment of Varying Anatomies and Post-procedure Follow-up
Patent foramen ovale (PFO) is present in 15% –30% of the general population and has been associated with various pathologic states, including cryptogenic stroke, platypnea–orthodeoxia syndrome, decompression sickness and migraine with auras. Transesophageal echocardiography (TEE) has a major role in the diagnostic evaluation of PFO, as wel l as in the post-procedural assessment after transcatheter closure. The goals of this article were to synthesize the echocardiographic transesophageal techniques required for accurate PFO diagnosis and careful anatomic assessment of its anatomic variants, to focus TEE indications for...

Thrombotic Thrombocytopenic Purpura Without Schistocytes: Beware of Misdiagnosis
A 43-year-old woman was admitted for acute unusual headache, vertigo, and left upper limb weakness. She had been complaining of asthenia for the past few weeks. Her medical history included uterine cervix cancer treated with conisation and 2 pregnancies without serious complications. No allergy or recent drug introduction was noted. After ruling out current pregnancy, magnetic resonance imaging (MRI) was immediately performed and showed recent ischemic strokes in multiple territories. Doppler ultrasound imaging showed no carotid or vertebral arteries lesion. Electrocardiogram showed no ST elevation or atrial fibrillation, ...

Point of care ultrasound detection of thrombus straddling a patent foramen ovale in a patient with acute chest syndrome
We report a case of a young woman with sickle cell disease who was hospitalized for vaso-occlusive crisis and subsequently developed worsening acute chest syndrome and stroke, discovered on point of care ultrasound to have right heart failure and a thrombus straddling a patent foramen oval. POCUS is highly specific for the detection of right heart dilation/dysfunction and should be a routine component of the assessment of acutely decompensating patients.PMID:36017251 | PMC:PMC9396226 | DOI:10.1016/j.rmcr.2022.101724

Synchronous multimode ultrasound for assessing right-to-left shunt: a prospective clinical study
ConclusionSynchronous multimodal ultrasound significantly improves the detection rate and test efficiency, quantifies RLS more accurately, and reduces testing risks and medical costs. We conclude that synchronous multimodal ultrasound has significant potential for clinical applications.
