Moderator band
The moderator band, also called the septomarginal trabecula, is a consistent structure in the morphologic right ventricle and can be helpful as a landmark in situations where the ventricles may be ambiguous (i.e. in some forms of congenital heart disease).
The term "septomarginal" is descriptiv...

Septal bounce
Septal bounce is a sign of ventricular interdependence on echocardiography, cardiac CT, and cardiac MRI, manifested by paradoxical interventricular septal movement during early diastole (i.e. initial septal movement towards and then away from the left ventricle) seen mainly in constrictive peric...

Arterial switch procedure
The arterial switch procedure, also known as the Jatene switch procedure, is an intervention designed to correct D-transposition of the great arteries (D-TGA) at the level of the aorta and main pulmonary artery. It is generally preferred over atrial switch procedures for simple D-TGA due to impr...

Peripartum/postpartum cardiomyopathy
Peripartum/postpartum cardiomyopathy is a dilated cardiomyopathy that may occur in the last trimester of pregnancy through the first several months postpartum.
Epidemiology
The estimated incidence in the United States ranges from one in 900 to one in 4000 live births, with an increased inciden...
Article
Coronary MR angiography
Coronary MR angiography (coronary MRA) is a developing approach to imaging the coronary arteries.
Advantages of coronary MRA include avoidance of the intravenous iodinated contrast and ionizing radiation used in coronary CT angiography and conventional angiography.
A disadvantage of coronary M...
Article
Senning repair
The Senning repair is one of two "atrial switch" procedures used to functionally correct transposition of the great arteries (the other being the Mustard repair).
The two repairs share a similar fundamental principle. Systemic blood flow is redirected away from the right ventricle and toward t...
Article
Patent foramen ovale
A patent foramen ovale (PFO) is a normal foetal interatrial connection which can persist into adult life. This can cause stroke due to paradoxical embolus.
Terminology
PFO is an anatomical variant due to persistence of a normal foetal structure rather than a malformation, in contradistinction ...
Article
Eustachian valve
The Eustachian valve, also known as the "valve of the inferior vena cava", is a ridge of variable thickness in the inferior right atrium. It is a remnant of a fetal structure that directed incoming oxygenated blood to the foramen ovale and away from the right atrium.
Radiographic features

Article
Coronary sinus
The coronary sinus is the largest cardiac venous structure. It returns the majority of the blood supply for the left ventricle to the right atrium.
Gross anatomy
The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. It normally drains int...
Article
Cardiac lymphoma
Cardiac lymphoma is a rare tumor of the myocardium and/or pericardium. It may be considered as primary or secondary.
Epidemiology
Primary cardiac lymphoma is a rare occurrence, representing only 10% of primary malignant cardiac tumors (1% of all primary cardiac tumors).
Secondary involvement ...

Cardiomyopathy in hemochromatosis
Cardiomyopathy in hemochromatosis refers to an iron overload cardiomyopathy which can occur in those with the condition.
In primary hemochromatosis leading to iron overload, the cardiomyopathy has classically been categorized as an infiltrative cause of restrictive cardiomyopathy. While in thos...
Article
Great cardiac vein
The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
Gross anatomy
It begins on the anterior surface of th...
Article
Stunned myocardium
Stunned myocardium refers to a situation in which an acute transient myocardial ischemic event results in a prolonged wall motion abnormality which eventually resolves.
The term is usually distinguished from "hibernating" myocardium, in which a chronic ischemic process leads to chronic left ven...
Article
Fontan procedure
The Fontan procedure is a repair surgical strategy for congenital cardiac anomalies. It is not usually used in isolation, but in combination with other repair procedures in a staged manner in an attempt to correct the underlying cardiac pathology.
Rationale
The procedure attempts to bypass the...
Article
Conus artery
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...
