ECHEVERRI, Juan G; MOSQUERA, Jannet  e  RESTREPO, Gustavo. Two-dimensional echocardiographic assessment of area and volume of the right atrium indexed to the body surface in a healthy population group. Rev. Colomb. Cardiol. [online]. 2015, vol.22, n.6, pp.270-276. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.06.014.

Objective: To determine the area and normal volume of the right atrium indexing it to the body surface by means of a two-dimensional echocardiogram in a health population group in order to obtain the baseline values for future studies of unhealthy population groups. Methods: Descriptive observational study. Results: 64 healthy patients were included, aged 17 to 68, who fulfilled all selection criteria. The average age was 34 years old (SD ± 12.19) and the male:female ratio was of 1:1.78, finding an average right atrium area of 12.2 cm² (SD ± 1.46), a minimum of 10 cm² and a maximum of 16 cm². In addition to this measurement, for this cavity the volume was also calculated, where an average of 28.7 mL, with a minimum of 19 mL and a maximum of 42 mL (SD ± 5.19) was observed. Conclusions: This is the first study in Colombia to report normal values indexed to the body surface of the area and volume of the right atrium in a healthy population group.
