Patent levoatrial cardinal vein without left heart hypoplasia

The Annals of Thoracic Surgery

We report a very rare case of a 38-year-old woman with an anomalous vein connecting the left atrium and superior vena cava. This vein originated from the roof of the left atrium and crossed the midline to join the normal right superior vena cava. Furthermore, there was no hypoplasia of the left heart, the atrial septum was intact, and all four pulmonary veins drained normally into the left atrium. Three-dimensional reconstructions and sagittal views on preoperative computed tomography clearly demonstrated a communication between the superior vena cava and the left atrium. The patient experienced increasing left-to-right shunt ratio and underwent successful surgical correction 3 years after the original diagnosis via ligation of the anomalous vein. This abnormal vein was considered to be a levoatrial cardinal vein. The embryology, physiology, diagnosis, and surgical repair of this rare lesion are discussed.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
