Interarterial course of anomalous right coronary artery: Pathophysiology, diagnosis, and treatment

Radiology Case Reports

Abstract

Anomalous coronary artery from the opposite sinus is a rare congenital anomaly that can present with symptoms similar to coronary artery disease, and sudden cardiac death. Management of anomalous coronary artery from the opposite sinus varies; however, current guidelines suggest surgery in symptomatic patients. Our patient is a middle-aged male with a history of coronary artery disease and status post coronary artery bypass graft. He presented with complaints of vague chest pain. After a positive stress test, he was sent to the catheterization suite. Diagnosis of an anomalous right coronary artery from the left coronary sinus was made. The patient underwent surgical revascularization and was awaiting follow-up with cardiology at the time of study. A timely diagnosis of an anomalous coronary artery is critical in symptomatic patients because of the risk of sudden cardiac death, especially in patients with arteries with an interarterial course. This case demonstrates the importance of making the correct diagnosis, as appropriate surgical management can drastically improve outcomes.

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
