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...
Patent foramen ovale
A patent foramen ovale (PFO) is a type of atrial septal defect in which there is channel-like communication between the atria through an unfused fossa ovale. Gross anatomy The foramen ovale in the interatrial septum normally develops into the fossa ovalis when the flaps of the atrial septa pri...
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. Incomplete regression of ...
The coronary veins return deoxygenated blood from the myocardium back to the right atrium. Most venous blood returns via the coronary sinus. Coronary venous anatomy is highly variable, but is generally comprised of three groups: cardiac veins which drain into the coronary sinus: great cardiac ...
The coronary sinus is the major coronary vein. It returns the majority of the left ventricular blood flow 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 into the right atrium. T...
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...
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...
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...
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...
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...
The circumflex artery (Cx) is a major coronary artery that divides off the left main coronary artery (the other branch being the left anterior descending (LAD) artery). Terminology The circumflex artery is referred to by multiple terms: circumflex artery (Cx) ramus circumflex artery (RCx) l...
Twiddler syndrome occurs when a patient manipulates (rotates) a subcutaneous chest device to the point of detaching and retracting the distal portion of the device. It is most commonly seen with implanted cardiac pacemakers or implantable cardiac defibrillators (ICDs). With continued rotation, ...

The Glenn shunt, also known as Glenn procedure, is a palliative surgical procedure for a variety of cyanotic congenital heart diseases. Rationale In this procedure, the systemic venous return is re-directed to the pulmonary circulation, bypassing the right heart 1-3. It can be used in a varie...
The Rastelli procedure is a surgical procedure to correct certain combinations of cardiovascular defects in patients with cyanotic congenital heart disease. Rationale The operation is based on a redirection of ventricular outflows using an intracardiac baffle that tunnels the left ventricle to...
