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.

We present a case report of a patient with a pulmonary embolus placed on venoarterial extracorporeal membrane oxygenation who developed venous cannula migration through an undiagnosed patent foramen ovale causing an ischemic stroke due to a thrombus and requiring thrombectomy and device closure of the atrial defect.

Conclusion: VTE can be detected in patients with CS linked to PFO. While –based on the presented literature–routine screening for VTE in patients with CS linked to PFO does not appear justified, history taking, and clinical exam should consider concomitant VTE. Whenever clinically suspected, the threshold to trigger ancillary testing for VTE should be low. Among patients with an acute PE and PFO, vigilance for new neurologic deficits should be increased, with a low threshold for brain imaging.

Rationale: Paradoxical embolism (PE) is an important cause of cryptogenic stroke, particularly in young patients, which usually have a relation with an unexpected route in circulation. Here we report a rare case of cryptogenic stroke carried 2 uncommon malformations. Patient concerns: A 48-year-old female experienced double neurological events in just 2 months. Diagnosis: Patent foramen ovale was diagnosed with transesophageal echocardiography and successfully occluded in the first admission due to stroke. In the second admission, chest tomographic angiography found a chordae shadow in the right middle lobe, was th...

We report a case of a 50 ‐year‐old male taxi driver who was diagnosed with a massive saddle pulmonary embolism, leg deep venous thromboembolism, and pending paradoxical embolus through a PFO with systemic embolization. The patient had an inferior vena cava (IVC) filter inserted immediately followed by surgical thromboem bolectomy and closure of PFO. He was discharged home 1 month after surgery. Surgery is the treatment of choice for preventing systemic embolization particularly cryptogenic stroke and its sequelae from pending paradoxical embolus. Preoperative IVC filter is a useful adjunct to prevent ongoing thromb oem...

Conclusion: Frequency of recent ischemic stroke in patients with symptomatic PE was higher in patients with PFO than in those without PFO. This finding supports the hypothesis that paradoxical embolism is an important mechanism of ischemic stroke in patients with PFO. Primary Funding Source: French Ministry of Health.

Conclusion An occult preexisting atrial fibrillation may lead to unnecessary percutaneous foramen ovale closure in a significant proportion of patients. A 6-month loop-recorder monitoring may improve the patient oriented decision-making.

We report the case of a 42-year-old female who was hospitalized for stroke. Detailed investigations revealed the existence of a PFO, pulmonary embolism, and ovarian vein thrombosis extending to inferior vena cava. She had a uterine myoma to be operated on but no other thrombophilic disorders. Anticoagulation therapy with direct oral anticoagulant successfully reduced the thrombus and prevented the recurrence of paradoxical embolism.

A 51-year-old man was diagnosed with eosinophilic granulomatosis with polyangiitis 6 years ago due to asthma, sinusitis, hypereosinophilia, and peripheral neuropathy based on the diagnostic criteria of American College of Rheumatology, and corticosteroid therapy achieved a remission. One year ago, he was hospitalized due to deep venous thrombosis (DVT) and pulmonary embolism, and rivaroxaban was administrated. He was admitted to our hospital for acute onset of diplopia and right hemiparesis. Peripheral blood examinations disclosed leukocytosis with hypereosinophilia.
