Anomalous left coronary artery from the pulmonary artery
Anomalous left coronary artery from the pulmonary artery (ALCAPA), also known as Bland-White-Garland syndrome (BWG), is a rare congenital coronary artery anomaly and is considered one of the most severe of such anomalies. There are two forms, based on onset of disease, each of which has differe...

Fractional flow reserve
Fractional flow reserve (FFR) is a technique to evaluate the hemodynamic relevance of coronary artery stenoses 1,2. It is defined as "the ratio of maximal flow achievable in the stenotic coronary artery to the maximal flow achievable in the same coronary artery if it was normal" 1. Fractional f...
Right coronary artery intra-cavitary course
Diagnosis almost certain
Published 16 Aug 2014
The conus artery is a small early branch off the right coronary artery (RCA) circulation. Gross anatomy Supply The artery has a variable distribution, but usually supplies a region of the anterior interventricular septum and the conus of the main pulmonary artery (hence its name). Variant an...
Diagonal branches of the left anterior descending artery
Diagonal branches of the left anterior descending coronary artery supply blood flow to the anterior and anterolateral walls of the left ventricle. There are usually denoted as D1, D2, D3, etc. There are termed "diagonal" due to them branching from their parent vessel at acute angles. They ext...
Intra-atrial course of the right coronary artery
Intra-atrial course of the right coronary artery is an uncommon anatomic variation in the course of the right coronary artery, usually involving the mid and distal segments, where the vessel partially or completely courses through the right atrial chamber. It is the most common intracavitary (in...

LCx and LAD arising separately from the left coronary sinus
One of the anatomical variants of coronary artery origin comprises the left circumflex coronary artery (LCx) and left anterior descending coronary artery (LAD) arising separately from the left coronary sinus. Hence there is no common left main coronary artery (LCA/LMCA). It considered the commo...
An uncommon variant of coronary arterial anatomy, Kugel's artery was originally described as an anastomotic communication between branches of the proximal left circumflex artery with the distal right coronary artery. These coronary trunks often communicate indirectly through atrial anastomotic n...

Congenital coronary ostial stenosis or atresia
Congenital coronary ostial stenosis and coronary atresia are intrinsic congenital coronary artery anomalies in which there is either an intrinsic narrowing or an absent coronary ostium. Epidemiology Coronary ostial stenosis and atresia are reportedly extremely rare conditions 1,2. Association...
Atrioventricular nodal artery
The atrioventricular (AV) nodal artery is a small artery supplying the atrioventricular septal area and the atrioventricular node. Gross anatomy The atrioventricular nodal artery usually courses through the inferior pyramidal space of the heart. Origin The origin of the atrioventricular noda...
