To assess reference values for left ventricular (LV) and left atrial (LA) dimensions, global LV function, and LV-myocardial mass for cardiac CT.

We examined 48 subjects undergoing a coronary CT angiography using 64-MDCT. All individuals had a low cardiovascular risk (no history of hypertension, diabetes, dyslipidemia, and smoking), normal ECG, negative biomarkers, and a normal cardiac CT examination. All subjects had a negative medical history of cardiovascular disease. The following measurements were obtained: septal wall thickness (SWT), posterior wall thickness (PWT), LV inner diameter (LVID), LA anterior posterior diameter (LAD), end-systolic volume (ESV), and end-diastolic volume (EDV), LV-myocardial mass (LVMM).

We found significant gender-related differences for SWT(sys), SWT(dia), PWT(sys), and PWT(dia) (12.8+2.4 vs. 10.3+2.1 mm; 9.5+1.9 vs. 7.3+1.3 mm; 15.2+2.5 vs. 13.5+2.7 mm; 10.6+2 vs.8.3+1.3 mm). LVID(sys), LVID(dia), LAD(sys), and LAD(dia) showed no significant difference between males and females (30.8+6 vs. 30+4.1 mm; 45.8+6.1 vs. 45.3+3 mm; 30+6 vs. 31.1+5 mm; 25+5.5 vs. 24.4+4.5 mm). Significant differences were not found for global LV functional parameters including ESV, EDV, SV, and EF (48.6+16 vs. 45.2+16.7 mm3; 123.1+28 vs. 110.3+30.6 mm3; 74.6+23.1 vs. 65.1+20.5 mm3; 59.9+11.1 vs. 58.7+10.3 %). LVMM showed significant gender-related differences (97.4+25 vs. 68.9+21.4 mm3).

This study provides gender-related reference values and percentiles for LV and LA quantitative measurements for cardiac CT and should assist in interpreting results.
