Left atrial isomerism associated with aneurysmal enlargement of right atrial appendage: A case report with literature review

open access: yesIndian Journal of Radiology and Imaging, 2019
We present a prenatally diagnosed case of heterotaxy syndrome (HS) in which left atrial isomerism (LAI) was associated with an aneurysmal enlargement of the right atrial appendage (RAA).

Normal pulmonary venous drainage in the setting of total anomalous pulmonary venous connection

open access: yesAnnals of Pediatric Cardiology, 2023
Total anomalous pulmonary venous connection (TAPVC) and anomalous pulmonary venous drainage are not synonymous. This has been described in the setting of right isomerism (bilateral right sidedness) where the pulmonary veins are connected anomalously but ...

Coordination polymers and isomerism; a study using silver(I) and a ∏-stacked ligand [PDF]

open access: yes, 2001
The ligand 2,5-bis(2-pyridylmethylsulfanylmethyl)pyrazine (L) was prepared by the base coupling of 2-(sulfanylmethyl)pyridine and 2,5-bis(chloromethyl)pyrazine. This new ligand was treated with AgClO₄ in a 1 1 metal-to-ligand ratio and with AgNO₃in a 2
