Atrial escape
Atrial escape refers to a chest x-ray sign of massive left atrial enlargement and is an exaggerated version of the double density sign.
Normally, the right border of the left atrium is not visible. As it enlarges it forms a distinct border projecting through the right heart shadow, medial to ...

Walking man sign (chest x-ray)
The walking man sign is seen on a lateral chest radiograph and is a sign of left atrial enlargement. It results from posterior displacement of the left main bronchus such that it no longer overlaps the right bronchus. The left and right bronchus thus appear as an inverted 'V', mimicking the legs...

Left ventricular aneurysm
Left ventricular aneurysms are discrete, dyskinetic areas of the left ventricular wall with a broad neck (as opposed to left ventricular pseudoaneurysms), thus often termed true aneurysms.
Epidemiology
True left ventricular aneurysms develop in less than 5% of all patients with ST-elevation my...

Pulmonary veins
The pulmonary veins drain oxygenated blood from the lungs to the left atrium. A small amount of blood is also drained from the lungs by the bronchial veins.
Gross anatomy
There are typically four pulmonary veins, two draining each lung:
right superior: drains the right upper and middle lobes
