Transesophageal Echocardiography in Cryptogenic Stroke and Patent Foramen Ovale: Analysis of Putative High-Risk Features From the Risk of Paradoxical Embolism Database Structural Heart Disease
Conclusions— We found no evidence that the proposed transesophageal echocardiography risk markers of large PFO size, hypermobile septum, and presence of right-to-left shunt at rest are associated with clinical features suggesting that a CS is PFO-attributable. Additional tools to describe PFOs may be useful in helping to determine whether an observed PFO is incidental or pathogenically related to CS.

Can neuroimaging differentiate PFO and AF-related cardioembolic stroke from the other embolic sources? Clinical-radiological correlation on a retrospective study
ConclusionIn clinical practice, PFO may be considered a cause of cortical stroke on the basis of radiological findings, when VB vascular territory or MS brain involvement is present in younger patients (<50 age).

Use of Magnetic Resonance Venography in Screening Patients With Cryptogenic Stroke for May-Thurner Syndrome
The purpose of this study was to determine the prevalence of May-Thurner syndrome (MTS) in patients with cryptogenic stroke and to determine the incidence of patent foramen ovale. Magnetic resonance venography of 214 patients with cryptogenic stroke and 50 control patients with abdominopelvic computed tomography scans were evaluated for MTS. Incidence of patent foramen ovale and MTS in the stroke group were significantly greater than the control group (P = 0.0001, P = 0.0023, respectively). In addition, there was significantly greater compression of the left common iliac vein in the stroke group (32%) compared with the control group (13%) (P

Endovascular aspiration to treat acute ischemic stroke caused by embolic carcinoma.
We report a rare case of large-cell, high-grade neuroendocrine lung cancer embolus occluding the basilar artery, which likely detached into the bloodstream from the lung after intruding into a pulmonary vein. The embolus was treated with endovascular aspiration, and achieved modified Thrombolysis In Cerebral Infarction 2c revascularization. After initial neurological recovery, the patient suffered respiratory arrest and support was withdrawn 48 h later. We discuss the tumor characteristics and implications for treatment of acute ischemic stroke in patients with cancer diagnoses. PMID: 30786802 [PubMed - as supplied by publisher]

Impact of Patent Foramen Ovale Anatomic Features on Right-to-Left Shunt in Patients with Cryptogenic Stroke
The purpose of this study was to investigate the impact of the morphologic characteristics of patent foramen ovale (PFO) on right-to-left shunt (RLS) in patients with PFO and cryptogenic stroke using transesophageal echocardiography and saline contrast transthoracic echocardiography (c-TTE). Of the 165 patients with PFO stroke, both the height and the length of PFO in the provoked RLS group were smaller than those in the constant RLS group. PFO height, interatrial septum mobility and proportion of atrial septal aneurysms were greater in the severe RLS group than in the mild and moderate RLS groups.

Importance of saline contrast transthoracic echocardiography for evaluating large right-to-left shunt in patent foramen ovale associated with cryptogenic stroke
In conclusion , TTE identified large RL shunt associated with CS with higher sensitivity and accuracy compared to TEE. Our findings suggest that the decision for device closure should be made based on the severity of RL shunt by TTE.

Concomitant AngioVac thrombectomy and patent foramen ovale closure in a patient with a large right atrial thrombus and recent paradoxical embolic stroke.
Abstract A 59-year-old male with a history of gallbladder adenocarcinoma receiving chemotherapy and on therapeutic anticoagulation for portal vein thrombosis presented to the emergency department via ambulance after being found unresponsive and in cardiac arrest. Initial workup upon return of spontaneous circulation revealed a large right atrial mass, patent foramen ovale (PFO), and bilateral acute cortical infarctions. This constellation of findings were concerning for PFO-related paradoxical embolic strokes. Given the risk of recurrent paradoxical embolic events and the absolute contraindication to thrombolysis ...

Atrial cardiopathy in young adults with embolic stroke of undetermined source: a myocardial deformation imaging analysis
ConclusionThis study shows that in our population atria cardiopathy and atrial function was not associated with ESUS.LAA structural and functional abnormalities may play a major role. The role of LAA in ESUS warrants further studies.

Detection of Right‐to‐Left Cardiac Shunt in the Absence of Transcranial Acoustic Bone
CONCLUSIONSWhen transcranial acoustic bone windows are missing, Doppler ultrasound of the cervical submandibular ICA and VAs are valid screening methods to detect RLS due to a PFO.

Significance of Echocardiographically Detected Central Venous Catheter Tip –Associated Thrombi
Conclusions In this sample with CVC tip–associated thrombi but without PFO or other intracardiac shunts, no embolic or other complications were detected, regardless of anticoagulation status. These data suggest a benign course for such thrombi and that anticoagulation, catheter removal, thrombectomy, and thrombolysis may be unnecessary when catheter tip–associated thrombi are incidentally detected on echocardiography.

New-onset atrial fibrillation following percutaneous closure of patent foramen ovale: a systematic review and meta-analysis.
CONCLUSIONS: The incidence of AF post-PFO closure was low across studies, with a high level of between-study heterogeneity. Until a concerted effort is made to improve accurate AF diagnosis, it will be difficult to gauge the association between transcatheter PFO closure and incidence of AF.
