Mitral stenosis/ regurgitation LVF LA myxoma VSD PDA
Double right heart border >75° splaying of carina with horizontal
orientation of left main bronchus Enlarged left convex left atrial appendage Increased density of chamber >7 cm distance b/w left main stem
bronchus and right lateral LA shadow
Increased convexity of posterio-superior cardiac margin
Posterior displacement of left main bronchus
Posterior displacement of barium filled esophagus
Tricuspid stenosis/ regurgitation ASD AF Ebstein anomaly Pulmonary atresia
Enlarges in rightward and posterior direction
Prominent round superior border at junction with SVC
>5.5 cm from midline to most lateral RA margin
>2.5 cm from right vertebral margin
Pressure overload: HTN, AS Volume overload: VSD, AR, MR Aneurysm Cardiomyopathy
Enlarges in post, inferior and leftward direction
Increased CTR Larger radius of curvature of left heart
border Downturned cardiac apex Depression of left hemidiaphragm
Increased convexity of posteroinferior cardiac margin
Hofman rigler rule: posterior cardiac margin projects >1.8 cm post to IVC measured at a point 2cm above intersection of IVC with right hemidiaphragm
PV stenosis Cor pulmonale ASD Tricuspid regurgitation Secondary to LVF
Only extreme dilatation causes signs on frontal view
Straightening/ convexity of left upper cardiac contour
Upturned cardiac apex Left upper cardiac margin parallels left main
stem bronchus as a long convex curvature Large appearance of MPA Occurs higher on the left heart border b/w
left ventricular contour and pulmonary outflow tract
Prominent convexity of ant heart border >1/3 distance from anterior cardiophrenic sulcus to sternal angle
Increased size prominent in retrosternal area
