One size doesn't fit all: exploring the influence of body size, age, and sex on right ventricle size measurements.

ABSTRACT:

Background

The assessment of right ventricular (RV) size is an important part of 2-dimensional transthoracic echocardiography. Current chamber quantification guidelines provide reference values as unindexed numbers, similar for men and women. We sought to evaluate normal ranges of RV dimensions based on age, sex, body surface area (BSA), and height. Consecutive patients with "normal echocardiogram" between January 2011 and August 2022 at our center were retrospectively included. RV dimensions including diameter at the base and mid-ventricle level, and base-to-apex length were measured.

Results

Of 1389 patients (median 43 years, 53% female) with all three measurements available, the median RV measurements, both unindexed and indexed to BSA, were: basal diameter 35.0 mm (31.0-
