Here, we present a case of an ischemic stroke, found to be due to an isolated extra-cardiac shunt without a patent foramen ovale. CASE PRESENTATION: A 56-year-old right-handed female with no significant past medical history presented with left-sided weakness concerning for acute stroke.

2022年5月16日 · Cardiac shunts are irregular patterns of blood flow in your heart. They’re often genetic, although some are linked to pregnancy factors. Shunt symptoms vary widely.

In predominately symptomatic patients with a mean age of 59 years and using electron beam computed tomography (EBCT), some type of extracardiac findings was present in 39%, with bronchial carcinoma confirmed in 2 individuals (0.1%) (10).

Extracardiac Shunt Hepatopulmonary Syndrome (see Hepatopulmonary Syndrome, [[Hepatopulmonary Syndrome]]) Diagnosis. Echocardiogram: bubble study (injection of agitated saline injected into vein) reveals shunt, with delayed appearance of bubbles (after 3-6 cardiac cycles) on left side of heart; Clinical. Hypoxemia (see Hypoxemia, [[Hypoxemia]])

2013年11月15日 · Here we describe an unexpected and novel cardio-pulmonary complication in HbSS, right-to-left shunting through extra-cardiac arterial-venous malformations (AVMs), which may contribute to pathophysiology. Extracardiac AVMs are rare in the general population, with an estimated incidence of 1/5000.
