Abstract
ObjectiveTo 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. MethodsDescriptive observational study. Results64 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. ConclusionsThis 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.
