Bottom Line: Normal echocardiographic reference values have been suggested previously, but detailed information about right-sided chambers and values according to gender was not included.Left ventricular (LV) dimensions increased, but LV volume decreased in older subjects.Right ventricular (RV) area decreased in women and older subjects, and the RV long-axis dimension showed a similar trend.

ABSTRACT

Background: Measurement of the cardiac chamber is essential, and current guidelines recommend measuring and reporting values for both sides of the cardiac chamber during echocardiographic evaluation. Normal echocardiographic reference values have been suggested previously, but detailed information about right-sided chambers and values according to gender was not included.

Methods: This is a prospective multicenter (23 centers) study evaluating normal Korean adult subjects using comprehensive echocardiography. We included normal adult subjects (age; 20-79 years old) who had no significant cardiac disorders or illnesses, such as hypertension or diabetes, which could affect cardiac structure and function. We measured the cardiac chamber including both right and left ventricles as well as atria according to current echocardiography guidelines and compared values according to gender and age groups.

Results: A total of 1003 subjects were evaluated and the mean age was 48 ± 16 years. Left ventricular (LV) dimensions increased, but LV volume decreased in older subjects. Right ventricular (RV) area decreased in women and older subjects, and the RV long-axis dimension showed a similar trend. Left atrial (LA) volume increased in men but there were no differences in LA volume index between men and women. The dimension of great arteries increased in men and older subjects.

Conclusion: Since there were considerable differences between men and women and in the different age groups, and the trends differed significantly between different echo variables, normal echocardiographic cutoff values should be differentially applied based on age and gender.

Measurement of right ventricular (RV) dimension and RV fractional area change in focused RV view. After obtaining RV focused view (A), mid (a), basal (b), and longitudinal RV dimensions (c) are measured at end-diastolic period (B). In the same view, RV end-diastolic area (d) and RV end-systolic area (e) are measured and RV fractional area change are calculated as (d - e) / d × 100% (C and D).

Figure 1: Measurement of right ventricular (RV) dimension and RV fractional area change in focused RV view. After obtaining RV focused view (A), mid (a), basal (b), and longitudinal RV dimensions (c) are measured at end-diastolic period (B). In the same view, RV end-diastolic area (d) and RV end-systolic area (e) are measured and RV fractional area change are calculated as (d - e) / d × 100% (C and D).

Mentions: The basal and mid RV short-axis dimension and the RV long-axis dimension were measured in the RV-focused apical 4-chamber view at end-diastole (Fig. 1A and B). RV end-diastolic and end-systolic area (RVEDA and RVESA) were also measured in the RV-focused apical 4-chamber view (Fig. 1C and D), and RV fractional area change (RVFAC) was calculated as follows: RVFAC (%) = (RVEDA - RVESA) / RVEDA × 100 (%). Proximal and distal RV outflow tract dimensions were measured on the parasternal short-axis view.
