Double right coronary artery diagnosed by computed tomographic angiography: A case report and systematic review of the literature.

Radiol Case Rep 2022 Jun 11;17(6):2058-2062. Epub 2022 Apr 11.

Department of Radiology, University of Pittsburgh, Pittsburgh, PA.

Double right coronary artery (RCA) is an extremely uncommon anomaly that is mostly detected incidentally in patients undergoing coronary angiography. It can be a benign and isolated anomaly or associated with other congenital abnormalities, mostly other coronary anomalies. Although atherosclerosis and myocardial ischemia have been frequently reported in patients with double RCA, this likely reflects that the patients were evaluated for chest pain rather than the predisposition to atherosclerosis in double RCA.

A Congenital Quadricuspid Aortic Valve Associated With Aortic and Mitral Regurgitation: Case Report and Literature Review.

Cureus 2021 Jan 29;13(1):e12986. Epub 2021 Jan 29.

Cardiovascular Diseases, University of Maryland Capital Region Health, Cheverly, USA.

Quadricuspid aortic valve (QAV) is a rare congenital cardiac anomaly that commonly becomes symptomatic in the fifth or sixth decade of life and can present as an isolated finding or in association with other congenital cardiovascular abnormalities. Previously, QAV was mainly a postmortem or intraoperative diagnosis and data was very limited on its natural history, associated complications, and long-term outcomes. In recent decades, however, there has been an increase in the reported cases of QAV, considering the advances in the diagnostic modalities such as transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and cardiac magnetic resonance (CMR).
