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

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 ...

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 Rare Case of Type IV Dual Left Anterior Descending Coronary Artery [PDF]

Journal of Clinical and Diagnostic Research, 2016
Coronary artery anomalies are usually asymptomatic and associated with other cardiac malformations. Dual left anterior descending coronary artery (LAD) is an uncommon congenital anomaly with four subtypes.

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

Anatomical variants and coronary anomalies detected by dual-source coronary computed tomography angiography in North-eastern Thailand [PDF]

, 2018
Purpose: Congenital coronary anomalies are uncommon, with an incidence ranging from 0.17% in autopsy cases to 1.2% in angiographically evaluated cases. The recent development of dual-source coronary computed tomography angiography (coronary CTA) allows ...

Short Chronic Total Occlusion Stump Creating an Optical Illusion of an Anomalous Coronary Artery: A Pseudo Anomaly

Journal of the Practice of Cardiovascular Sciences, 2023
Coronary artery anomalies are often asymptomatic and detected incidentally during coronary angiography, cardiac surgery, or autopsy. However, sometimes in chronic total occlusion, the distal part of a vessel is well collateralized from the contralateral ...

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‐

Near-infrared spectroscopy study of tourniquet-induced forearm ischaemia in patients with coronary artery disease [PDF]

, 2001
Near-Infrared Spectroscopy (NIRS) can be employed to monitor local changes in haemodynamics and oxygenation of human tissues. A preliminary study has been performed in order to evaluate the NIRS transmittance response to induced forearm ischaemia in ...

Great Vessel and Coronary Artery Anatomy in Transposition and Other Coronary Anomalies

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.
