Altered hypoxia‐inducible factor‐1 alpha expression levels correlate with coronary vessel anomalies [PDF]

Developmental Dynamics, 2009
AbstractThe outflow tract myocardium and other regions corresponding to the location of the major coronary vessels of the developing chicken heart, display a high level of hypoxia as assessed by the hypoxia indicator EF5. The EF5‐positive tissues were also specifically positive for nuclear‐localized hypoxia inducible factor‐1 alpha (HIF‐1α), the oxygen‐

The Role of MDCT Coronary Angiography in the Detection of Benign Varieties and Anomalies of Coronary Blood Vessels-A Narrative Review. [PDF]

Medicina (Kaunas)
Coronary arteries may vary in quantity, point of origin, or course. These variations fall under the category of anatomical variants/anomalies of the coronary arteries, representing congenital abnormalities of the coronary vascular system. Generally, they are benign, asymptomatic, and identified inadvertently during coronary angiography conducted for ...

Great Vessel and Coronary Artery Anatomy in Transposition and Other Coronary Anomalies [PDF]

JACC: Cardiovascular Imaging, 2013
In patients with transposition of the great arteries, the identification of coronary anatomy is fundamental to optimal surgical outcome. A number of classifications describing the coronary vessels' origin and course in transposition of the great arteries have been published. However, all are limited to operative or pathological case series.

Coronary Artery Anomalies in Review: Anomalous Origin, Aneurysms, and Fistulae [PDF]

Methodist DeBakey Cardiovascular Journal
Coronary artery anomalies are rare congenital abnormalities involving abnormal coronary artery origin and incomplete/abnormal vessel development. These anomalies encompass a broad anatomical spectrum with varied clinical presentations ranging from sudden

Conus branch fistula to main pulmonary artery: a rare coronary anomaly that may cause chest pain in a pediatric patient [PDF]

European Journal of Case Reports in Internal Medicine
Coronary artery fistulas (CAFs) are rare congenital coronary anomalies where abnormal communication develops between coronary arteries and cardiac chambers or a thoracic great vessel. CAF is usually diagnosed incidentally with cardiac imaging.

A Case of Coronary Vessel Anomaly of the Left Circumflex Artery Originating from the Right Coronary Artery with Variant Angina

Korean Circulation Journal, 2004
Coronary vessel anomaly is a rare disease, with an incidence of about 0.6-1.3% of patients receiving coronary angiography. The ischemia in coronary vessel anomalies is due in most cases to atherosclerosis or compression of the coronary artery by a great vessel, but occasionally spasm of a coronary vessel anomaly is responsible for the pathogenesis of ...

A life-threatening association of coronary anomalies [PDF]

Journal of Clinical and Scientific Research, 2016
Anomalous origin of the left coronary artery from the right sinus of Valsalva, even though rare, has been documented well in literature. However the association of this anomaly with coronary fistulae has been rarely reported so far. We report the case of
