Diagnostic radiology of cardiovascular 2009
The right atrium is the most troublesome chamber to evaluate. It overlaps the right ventricle and when that chamber is also enlarged (as is true in most conditions causing right at rial enlargement) , the determination of right atrial size is attended by considerable difficulty.

There are signs of right atrial enlargement that include increased height and outward bulge of the right atrial segment of the right cardiac contour on the frontal chest radiograph." Heart Size

Right atrial (RA) enlargement is less common, and harder to delineate on chest radiograph, than left atrial (LA) enlargement. Pathology Etiology Enlargement of the right atrium (RA) can result from a number of conditions, including: raised right ventricular pressures pulmonary arterial hypertension cor pulmonale valvular disease

10 Radiology of Cardiac Disease. Posteroanterior (PA) and lateral chest radiographs taken in inspiration are standard for evaluation of cardiac size and contour. On the PA chest radiograph, the right cardiomediastinal border is formed by the superior vena cava (SVC) and the right atrium; the left cardiomediastinal border is formed by the aortic.
Cardiomegaly with Biatrial Enlargement CXR
Cardiac chamber enlargement has been implicated as an important biomarker in the prediction of morbidity and mortality for an array of cardiovascular processes, including atrial fibrillation, myocardial infarction, stroke, and heart failure ( 1 - 5 ).
Left atrial enlargement (due to mitral valve regurgitation) Radiology Case
The right atrium (RA) is the cardiac chamber that has been least well studied. Due to recent advances in interventional cardiology, the need for greater understanding of the RA anatomy and physiology has garnered significant attention.

Purpose To assess the role of long-axis (LA) and short-axis (SA) measurements of the right atrium (RA) and right ventricle (RV) at non-electrocardiographically (ECG) gated thoracic CT angiography for identification of RA enlargement and RV enlargement. Materials and Methods This study was a retrospective case review of 138 patients who underwent both non-ECG-gated CT angiography and ECG.
Biatrial enlargement on CXR All About Cardiovascular System and Disorders
Cardiomegaly is a catch-all term to refer to enlargement of the heart, and should not be confused with causes of enlargement of the cardiomediastinal outline, or enlargement of the cardiac silhouette . Pathology Etiology There are many etiologies for cardiomegaly: congestive heart failure ischemic heart disease

Cardiac chamber enlargement can be recognized by cardiac contour changes, new or different interfaces with adjacent lung, and/or displacement of adjacent mediastinal structures. These are discussed separately: right atrial enlargement right ventricular enlargement left atrial enlargement left ventricular enlargement
Right atrial enlargement wikidoc
The right atrium is considered enlarged when the right aspect of the cardiac silhouette on the posteroanterior chest radiograph enlarges. For adults, extension of the right heart border 5 cm or greater from the midline on the posteroanterior projection is considered suggestive of right atrial enlargement [ 1 ].

Introduction. Cardiac chamber enlargement has been implicated as an important biomarker in the prediction of morbidity and mortality for an array of cardiovascular processes, including atrial fibrillation, myocardial infarction, stroke, and heart failure (1-5).Despite the ubiquity of non-electrocardiographically (ECG) gated multidetector CT of the chest and the nearly universal comment of.
Left atrial enlargement Radiology Case
Right atrial enlargement had the highest R 2 values, which indicates that variability in right atrial enlargement explains a higher proportion of variation in both maximum heart diameter and CTR than enlargement of the other cardiac chambers (Figure 4). Overall, enlargement of any cardiac chamber explained 23.0% of variation in CTR and 28.7% of.
Pacemaker Chest X Ray
The right atrium ( RA) (plural: atria) is one of the four chambers of the human heart, and is the first chamber to receive deoxygenated blood returning from the body, via the two venae cavae. It plays an important role in originating and regulating the conduction of the heart. Gross anatomy
Left atrial enlargement while echocardiography has emerged as the preferred tool for assessing
Right atrial enlargement occurs when the right atrium, one of the heart's upper chambers, is larger than normal. The right atrium is the first entry point of blood returning to the heart from circulating in the body.

RA enlargement was described for several diseases such as chronic pulmonary hypertension, pulmonary embolism (PE), COPD, dilated cardiomyopathy, right atrial myocardial infarction and AF 7,8,17,20.
