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.

Right atrial enlargement means your heart has an abnormally large right atrium. This upper chamber of your heart receives oxygen-poor blood from your body. High blood pressure and blood volume cause right atrial enlargement. This usually means you have an issue with your heart or lungs that's causing all of this.
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.
MBBS Medicine (Humanity First) Chest radiograph of different conditions
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

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

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 ).
A detailed understanding of the structures that make up the normal contours of the heart and
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.
Left atrial enlargement Radiology Case
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.
Mogul signs on chest Xray 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
Pacemaker Chest X Ray
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

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.

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 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.

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.
