Right atrial pathologic findings can be broadly categorized into (a) congenital anomalies (cor triatriatum dexter, Ebstein anomaly, and aneurysm), (b) disorders of volume (tricuspid regurgitation, pathologic mimics such as a pseudoaneurysm, and atrial septal defect), (c) disorders of pressure (tricuspid stenosis, restrictive cardiomyopathy, and.

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
Diagnostic radiology of cardiovascular 2009
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.

Conclusion. RA enlargement was independently associated with an increased risk of HF, stroke, systemic embolization or death in patients with non-valvular AF, suggesting that RA volume can be helpful in assessing future cardiovascular risk in this population. Keywords: atrial fibrillation, left atrium, right atrium, heart failure, stroke.
Left atrial enlargement while echocardiography has emerged as the preferred tool for assessing
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 ).

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.
A detailed understanding of the structures that make up the normal contours of the heart and
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

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.

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.
Diagnostic radiology of cardiovascular 2009
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 ].
Left atrial enlargement Radiology Case
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.
MBBS Medicine (Humanity First) Chest radiograph of different conditions
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.

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
