Many Different and Interesting Shapes of the Heart on Frontal View – mostly involving CHD
But in Adults There are Two Basic Common Shapes of Cardiomegaly
NORMAL AND TWO BASIC TYPES OF CARDIOMEGALY
The normal heart (above) is a combination of a triangle and an oval. Cardiomegaly on CXR is mostly assessed by an increased cardiothoracic ratio, and takes on two basic forms based on the overall shape of the heart; the ovoid form (bottom left) which suggests left ventricular dominance and triangular form (bottom right) which suggests right ventricular dominance.

How to Diagnose Cardiomegaly
Cardiothoracic Ratio
Cardiomegaly -2 different entities
The Ovoid Form of Cardiomegaly – Consider LVE
Vector of the Enlarging LV – Rotate Down and to the LeftVECTOR FOR LV ENLARGEMENT DOWN AND OUT The left ventricle (LV) enlarges in a posterior, downward and lateral direction resulting in the characteristic changes of LVE on CXR Ashley Davidoff MD
Clinical Exam – Focal LV Thrust
The Triangular Form of Cardiomegaly – Consider RVE
Note the Basic Shape of the RV in almost all Views
Vector of the Enlarging RV – Rotate Laterally to the Right
Clinical Exam – Parasternal Heave
What about the Right Atrium (RA) and Right Heart Border?
The RA does not make much a statement on the frontal CXR
The right atrium is the most difficult chamber to assess unless it is very large in which case it will present on the frontal CXR with a very large right paravertebral border.
The Left Atrium

Carinal Angle
Double Density

The Carina and the Carinal Angle
NORMAL FRONTAL CXR NORMAL ASYMMETRIC BRANCHING OF MAINSTEM BRONCHI
The normal CXR shows the characteristic asymmetric branching of the main stem bronchi. The right is short and stout and slightly more vertical while the left is long and thin and slightly more obtuse.
The normal carinal angle is between 40-80 degrees.

ASYMMETRIC BRANCHING PATTERN ? RIGHT SHORT AND STOUT AND THE LEFT LONG AND THIN
CARINAL ANGLE ? 40-80 degrees

Assessing Chamber Involvement
The Ovoid Cardiomegaly
Be Careful – Good Inspiration vs Poor Inspiration
CXR- NORMAL and MITRAL STENOSIS
Two different patients showing the normal patient on the left and the CXR of a patient with an enlarged triangular shaped heart on the right. The triangular heart with upturned apex is characteristic of right ventricular enlargement, and the elevation of the carina and a double density seen on the right side of the heart suggests left atrial enlargement. These findings are consistent with rheumatic mitral stenosis.

CXR ? NORMAL AND PULMONARY EDEMA
Normal (upper)and Pulmonary Edema (lower)
The patient with acute myocardial infarction may have a normal chest examination but if there is extensive myocardial damage to impede pump function, pulmonary edema (right) results.
