Unlabelled: Right-to-left shunt may be a cause of paradoxical embolization (and cryptogenic cerebral ischemic events). Patent foramen ovale and pulmonary arterio-venous malformations are the most common cause of paradoxical embolization; however, some rare cardiovascular lesions may cause a right-to-left shunt with consequent paradoxical embolization. We describe a case of a young child with superior sinus venosus atrial septal defect who underwent surgical closure and developed a cryptogenic cerebral ischemic attack due to a rare cause of paradoxical embolization, during a long-term follow-up.

Background: In neonatal vein of Galen aneurysmal malformation, vein of Galen aneurysmal malformation echocardiography remains the mainstay for early detection and explains various haemodynamic changes occurring due to a large systemic arterio-venous shunt. However, there is limited evidence of echocardiography in risk stratifying neonatal vein of Galen aneurysmal malformation vein of Galen aneurysmal malformation. The objective of this study was to identify echocardiographic parameters that could be associated with major outcomes and guide timing of neuro-intervention.

From the Department of Radiology, Mayo Clinic, 200 1st St SW, Rochester, MN 55905-0002 (P.S.R.); Speciality Hospital, IMMS Western National Medical Center, Guadalajara, Mexico, and UdG, Health Science University Center, Guadalajara, Mexico (M.J.S.); Department of Cardiology, University of Iowa Stead Family Children's Hospital, Iowa City, Iowa (R.A.); and Pediatric Hospital, Western National Medical Center, IMSS, Guadalajara, Mexico, and Imaging and Diagnostic Center CID, Guadalajara, Mexico (H.G.).

Palliative procedures are performed for congenital heart diseases that are not amenable for definitive surgical procedures or as a component of hybrid procedures along with transcatheter interventions. Multimodality imaging plays an important role in the follow-up of these palliative procedures, mainly for the timely detection of complications and for planning any subsequent palliative or definitive procedure. Echocardiography is the first-line imaging modality, with CT and MRI used as complementary techniques in indeterminate cases.
