OBJECTIVE: Published cardiac CT angiography (CTA) reference measurements for the cardiac chambers, aorta, and pulmonary artery (PA) are incomplete and compromised by study population, coronary artery disease (CAD), or its risk factors. The purpose of our study was to establish sex-specific normalized ranges of cardiac chamber size, wall thickness, ejection fraction (EF), and aorta and PA diameter on cardiac CTA in a population without CAD or its risk factors. MATERIALS AND METHODS: Seventy-six patients (38 men and 38 women) without known diabetes; hypertension; smoking history; or evidence of structural heart, vascular, or coronary artery diseases underwent 64-MDCTA. Obtained left atrial (LA) size, left ventricular (LV) volumes, LV wall thickness, thoracic aorta, and PA diameter measurements were normalized to body surface area (BSA). RESULTS: There were statistically significant differences noted between men and women for all measured left-sided heart and great vessel measurements. After normalization to BSA, only chamber dimensions and ascending aorta and left PA sizes remained significantly different. Selected normalized measurements for men versus women, respectively, include LA area, 10.6 ± 2.1 versus 12.3 ± 2.1 cm²/m²; LV end-diastolic size, 72.4 ± 15.1 versus 60.9 ± 13.3 mL/m²; EF, 67% ± 7% versus 72% ± 8%; aortic sinus, 1.6 ± 0.2 versus 1.7 ± 0.2 cm/m²; ascending aorta, 1.4 ± 0.2 versus 1.6 ± 0.2 cm/m²; descending aorta, 1.1 ± 0.1 versus 1.2 ± 0.1 cm/m²; main PA, 1.3 ± 0.1 versus 1.4 ± 0.1 cm/m²; right PA, 1.1 ± 0.1 versus 1.1 ± 0.2 cm/m²; and left PA, 1.0 ± 0.1 versus 1.1 ± 0.1 cm/m². CONCLUSION: Cardiac CTA measurements of the left cardiac chambers, thoracic aorta, and pulmonary arteries were established for a population without CAD or its risk factors.
