Article
Coronary arteries
The coronary arteries arise from the aortic sinuses immediately distal (superior) to the aortic valve and supply the myocardium of the heart with oxygenated blood. The arteries branch to encircle the heart covering its surface with a lacy network, perhaps resembling a slightly crooked crown.

Shaggy heart border
The shaggy heart border is a descriptive term referring to an ill-definition of the cardiac silhouette on a chest radiograph. Due to its imprecise nature, some caution is advised against its use in radiological reports 4.
It usually implies pleural disease on the mediastinal interface 3 and may...

Primary cardiac tumors
Primary cardiac tumors are uncommon and comprise only a small minority of all tumors that involve the heart: most are mediastinal or lung tumors that extend through the pericardium and into the heart, or metastases 1.
Epidemiology
Primary cardiac tumors have an estimated autopsy prevalence of ...

Primary benign cardiac tumors
Primary benign cardiac tumors are much less common than secondary metastatic deposits. However, they are more likely when a cardiac mass is seen outside of the setting of terminal metastatic disease. Tumors include 1,2:

Article
Primary malignant cardiac tumors
Primary malignant cardiac tumors are rare and account for only ~25% of primary cardiac tumors, and only a small proportion of all malignant tumors which involve the heart: direct extension of adjacent tumors or metastatic deposits are far more common.

Sarcoidosis (cardiac manifestations)
Cardiac involvement of sarcoidosis is a manifestation of sarcoidosis which is often asymptomatic, although can be associated with high mortality 8. Autopsy studies show prevalence of ~25% cardiac involvement, yet only 5-10% are found symptomatic 1,2.
Sarcoidosis is a multisystem disorder chara...

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 the onset of the disease, each of which has...

Differential diagnosis for a small cardiothoracic ratio
A small cardiothoracic ratio (CTR) is defined as <42%/0.42 when assessed on a PA chest radiograph, and is often called small heart syndrome. A pathologically-small heart is also known as microcardia.
It can be due to/associated with a number of entities:
adrenal insufficiency, e.g. Addison...
