Coronary artery anomalies: A diagnostic challenge [PDF]

, 2011
Coronary artery anomalies (CAAs) are found in approximately 1% of all patients undergoing coronary angiography and in 0.3% of patients undergoing autopsy (Roberts, 1986). CAAs may be classified into those of origin and course, intrinsic coronary arterial

Sinus of Valsalva aneurysm and bicuspid aortic valve: detection and mechanism by cardiac magnetic resonance imaging

Clinics and Practice, 2011
Cardiac magnetic resonance imaging (CMR) demonstrated a sinus of Valsalva aneurysm (SVA) with severe dilatation of the right coronary sinus in association with a congenital bicuspid aortic valve (BAV) and subaortic membrane. The SVA had not been apparent

Angiographic anatomical variation of origin of left circumflex coronary artery in Basrah [PDF]

The Medical Journal of Basrah University, 2017
Background: The left circumflex coronary artery normally originated from left coronary artery , however, this artery may change its origin either from left aortic sinus or from right aortic sinus.

Left Main Compression by a Giant Aneurysm of the Left Sinus of Valsalva: An Extremely Rare Reason for Myocardial Infarction and Cardiogenic Shock

Case Reports in Cardiology, 2015
Aneurysms of the sinus of Valsalva are very rare and mostly located in the right coronary sinus. They might course with dyspnea, fatigue, and acute coronary syndromes.

Anomalous origin of the right coronary artery from the left coronary sinus with medusa head left coronaries: Plethora of left coronary circulation with paucity of right one

Research in Cardiovascular Medicine, 2021
We report a rare case of anomalous origin of right coronary artery (RCA) from the left coronary sinus with a peculiar medusa head pattern of left coronary system in an octogenarian presenting with inferior wall myocardial infarction.

Reconsidering the back door approach by targeting the coronary sinus in ischaemic heart disease

Heart, 2016
Coronary sinus interventions (CSI) are a class of invasive techniques (surgical and percutaneous) originally proposed in the first half of the 20th century, aiming to treat ischaemic heart disease by acting on the venous coronary system.

The anatomy of interatrial communications - what does the interventionist need to know? [PDF]

, 2008
Increasingly, the interventional cardiologist is seeking to close interatrial communications by inserting devices by means of catheterisation. So as to optimise these procedures, it is adavantageous to have a firm grasp of the anatomy of the normal ...
