Gone with wind: a novel biodegradable occluder for percutaneous closure of patent foramen ovale
A 42-year-old man with a history of cryptogenic stroke and sequela free after medical therapy was found to have a patent foramen ovale (PFO) by transoesophageal echocardiography (TEE,Panel A, arrowhead indicates the PFO; Ao, aorta; LA, left atrium; RA, right atrium). Given a RoPE score of 7, he was referred for percutaneous PFO closure. A 24  mm × 24 mm fully biodegradable occluder (Pancy® occluder, ChiCTR1900024036,Panel E, arrowhead indicates marker) was delivered and deployed via a 10-Fr sheath (Mallow® delivery system) under florescent angiography and TEE (Panel B, arrowhead indicates the marker on occluder while ...

Intracranial Hemorrhage as a Marker for Mycotic Aneurysm in Patients With Infective Endocarditis
Discussion Patients with left-sided and right-sided endocarditis with PFO and ICH on CNS imaging were more likely to have mycotic aneurysms detected through DSA than similar patients without ICH. Routine DSA screening for mycotic aneurysms may not be required in patients with endocarditis undergoing evaluation for valve surgery who present without ICH on CNS imaging.

E-135 Dejerine-roussy syndrome in the setting of right sigmoid sinus thrombosis: a unique case report
DiscussionThis case illustrates the important clinical aspects and physical findings needed to diagnose DRS. The presence of focal allodynia and hyperalgesia with recent cerebrovascular incidents provides significant evidence for DRS. The purpose of this case is to provide awareness and to increase clinical suspicion of DRS during examination, especially in the setting of cerebral venous sinus occlusion as infarction alone may not present as atypical allodynia.Disclosures S.

Patent Foramen Ovale Closure Challenged by Left Atrial Chord
In a 22-year-old woman suffering from ischemic stroke affecting the posterior cerebral artery, clinical work-up ruled out cardiovascular and neurological pathologies except patent foramen ovale (PFO) with septal aneurysm and complete bubble filling of the left atrium as demonstrated by echocardiography. The patient was scheduled for transcatheter PFO closure. Peri-interventional 3-dimensional transesophageal echocardiography revealed a PFO tunnel and a left atrial chord keeping the PFO open, with consequent continuous left to right shunting (A to C; Online Video 1). Balloon sizing demonstrated a tunnel diameter of 16 mm (D...

Clot Through the Heart: Paradoxical Embolism With Thrombus-in-Transit at Multidetector Computed Tomography
We present the case of a 67-year-old man with concomitant stroke and pulmonary embolism 1 day after radiofrequency catheter ablation for refractory atrial tachycardia. A chest computed tomographic angiogram revealed “thrombus-in-transit” across a patent foramen ovale, confirming the diagnosis of paradoxical embolism. Paradoxical embolism is a rare definitive diagnosis. Our case is a key demonstration of the even rarer instance where such a diagnosis is confirmed at multidetector computed tomography.

Paradoxical brain embolism shadowing massive pulmonary embolism
Patent foramen ovale is frequently observed in the general population. In case of massive pulmonary embolism, the sudden increase in the right heart cavity's pressure may cause a right-to-left shunting across this foramen, which could be associated with conflicting outcomes. Herein, we report a case of reversible cardiac arrest preceded by seizures, and followed by hemodynamic stability without any vasopressor. A brain CT-scan showed a limited ischemic stroke. Initial echocardiographic assessment revealed an acute cor pulmonale and a right-to-left intracardiac shunt across a large patent foramen ovale, suggesting the diagn...
