Abstract

Arteriovenous malformations may lead to right-heart failure in cases of hemodynamically significant left-to-right shunting. Here, we report the case of a 37-year-old female who presented with congestive heart failure related to an isolated anomalous connection of the left pulmonary vein to the left brachiocephalic vein (partial anomalous pulmonary venous connection). After successful reconnection to the left appendage and clinical improvement, the patient once again developed progressive signs of heart failure. Several arteriovenous malformations were identified in the liver as the underlying cause of the patient's high-output heart failure, and the patient was retrospectively diagnosed with hereditary hemorrhagic telangiectasia. Target embolization led to right-ventricular remodeling, and persistent clinical improvement. To our knowledge, this is the first report of two rare AV-malformations with left-to-right shunting and progressive right-heart failure in a single individual.

COVID-19

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
