Coronary veins

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 ...

Coronary sinus

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...

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...

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...
Article

Circumflex artery

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

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, ...

Glenn shunt

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...

Rastelli procedure

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...
