Paradoxical embolism through a patent foramen ovale from central venous catheter thrombosis: A potential cause of stroke
Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism.A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thu...

Epidemiology of Patent Foramen Ovale in General Population and in Stroke Patients: A Narrative Review
Conclusions: Given the limitations of autopsy and TEE studies, there is good reason not to take a fixed 25% PFO prevalence for granted. The estimation of degree of causality may be underestimated or overestimated in populations with PFO prevalence significantly lower or higher than the established. Given the high sensitivity, non-invasive nature, low cost, and repeatability of TCD, future large-scale TCD-based studies should investigate potential heterogeneity in PFO prevalence in different healthy racial/ethnic populations.

Acute Ischemic Stroke as a Result of Paradoxical Embolus in a Patient with Renal Cell Carcinoma, Intravenous Tumor Thrombus Extension, and Patent Foramen Ovale
Conclusions: This is the first reported case of intraoperative paradoxical embolism in the setting of RCC with cavoatrial extension and PFO. The presence of PFO may be a risk factor for severe cerebrovascular complications in the surgical management of RCC with venous involvement.

Bubble Test and Carotid Ultrasound to Guide Indication of Transesophageal Echocardiography in Young Patients With Stroke
ConclusionsBubble test and carotid ultrasound could be used for the individual decision for/against TEE in patients with cryptogenic stroke ≤60 years. If they are unremarkable, TEE can be omitted with high safety regarding secondary prevention. If bubble test is positive and/or carotid ultrasound shows atherosclerosis, TEE should be carried out if PFO or aortic atheroma are potentially relevant for further patient management.

Increased Blood Residence Time as Markers of High-Risk Patent Foramen Ovale
AbstractPrevious investigations have suggested that patients with patent foramen ovale (PFO) often have an atrial dysfunction, like to that observed in patients with atrial fibrillation (AF) which may concur to an increased risk of cryptogenic stroke. The aim of the study is to compare the atrial resident time (Rt) of PFO patients to those with sinus rhythm (SR) and AF using patient-specific 3D computational fluid dynamics (CFD) analysis. Models of left atrium (LA) hemodynamics were obtained from time-resolved CT scans and transthoracic echocardiography (TTE). Enrolled patients were divided into three groups: 30 healthy su...

Modified risk of paradoxical embolism more effectively evaluates the risk of stroke associated with patent foramen ovale
CONCLUSION: LDL-C levels and transverse diameter of the left atrium were identified as independent risk factors for PS. The modified RoPE scoring system exhibited superior performance in assessing the risk of PS compared to the original RoPE score.PMID:37622702 | DOI:10.2174/1567202620666230825103401

Residual Shunt after Patent Foramen Ovale Closure: Preliminary Results from Italian Patent Foramen Ovale Survey
Conclusions: PFO closure is a safe procedure. rRLS is not uncommon but large rRLS is rare. Clinical complications, mostly related to cardiac arrhythmias, are not unusual. Evaluation of the data of the whole survey is underway.

Can Transthoracic Echocardiography Be Useful Detecting Patent Foramen Ovale In Stroke? The Of Valsalva Maneuver (P4.231)
CONCLUSIONS: TTE and TCD can be more useful than TEE to detect right-to-left shunt. This outcome may be related with the better effectiveness of the Valsalva maneuver with TTE or TCD than with TEE. The shunt detection by TTE or TEE was not related with its magnitude.Study Supported by: NoDisclosure: Dr. Iglesias Mohedano has nothing to disclose. Dr. Diaz Otero has nothing to disclose.

Amusia: Unique Presentation of Stroke (P6.261)
CONCLUSIONS:Even though music and speech are similar in principle and execution they are functions of different hemispheres of the brain. Unlike aphasia, anatomical localization of amusia has not been established but it is known that right non dominant hemisphere is concerned with musical ability. Impairment of musical ability in the presence of intact speech can be the only presenting finding in stroke. Their identification is the key to early and appropriate treatment.Study Supported by:NoneDisclosure: Dr. Ramchandani has nothing to disclose. Dr. Alsmaan has nothing to disclose.
