Reference Values for and Determinants of Right Atrial Area …


Nov 29, 2012 · Right atrial (RA) size is important in screening, diagnosis, and follow-up assessment in patients with pulmonary hypertension. The objective of this study was to define normal reference values for RA area by echocardiography in a large population of athletic versus sedentary healthy subjects.

Echocardiographic Evaluation of the Right Atrial Area …


Background: Right atrial area (RAA) is a prognostic factor in human patients with pulmonary arterial hypertension (PAH). Reference intervals for RAA have been described in healthy dogs. Objectives: To evaluate RAA indexed to the body surface area in dogs with PAH as an indicator of right atrial size, PAH severity and right-sided congestive heart failure (R-CHF).

Atrial Areas – Cardiac MRI


Atrial Areas. Quantifying Atrial Areas. Tracing the boundaries of both atria on the 4-chamber view may provide an accurate measure of their area (cm 2).). Traces of the atria should be completed at the end systolic phase—where they are at their largest throughout the cardiac cycle.

Right atrial to left atrial area ratio on early …


Right atrial to left atrial area ratio on early echocardiography predicts long-term survival after acute pulmonary embolism. A RA/LA Ratio >1.0 at presentation with acute PE was associated with a three-fold increased risk of long-term mortality.

Normal reference ranges for left and right atrial volume …

  • Left atrial (LA) size is part of cardiac remodelling in a variety of cardiovascular diseases and a strong predictor of cardiovascular morbidity and mortality. 1–4As a contrast to numerous studies on the significance of LA enlargement, data on the clinical significance of right atrium (RA) enlargement are sparse. The assessment of RA enlargement is of importance, sinc…
