Left atrio-vertebral ratio: A new computed-tomography measurement to identify left atrial dilation

Highlights • Left atrium dilation is a frequent condition often unrecognized on CT scan. • Left atrium dimensions are proportional to a patient’s build. • LAVR is the first CT measurement directly scaling the left atrium to a body element available on the image. • The LAVRs are significantly higher...

Zusammenfassung:	Highlights • Left atrium dilation is a frequent condition often unrecognized on CT scan. • Left atrium dimensions are proportional to a patient’s build. • LAVR is the first CT measurement directly scaling the left atrium to a body element available on the image. • The LAVRs are significantly higher in patients with cardiogenic pulmonary oedema. • A LAVR >2.1 suggests left atrial dilation.
