Background: Aortic knob enlarges in many cardiovascular disorders including hypertension. It can be easily evaluated in chest radiographs. The study was carried out to document and analyze measurements of aortic knob in normal and hypertensive population in chest radiograph. Methods: This descriptive cross-sectional study was performed in the Department of Radiology and Imaging, Tribhuvan University Teaching Hospital (TUTH) and Manmohan Cardiothoracic Vascular and Transplant Center (MCVTC) from July to October 2019. Postero-anterior (PA) chest radiographs of 200 individuals (100 normal and 100 hypertensives) between the age of 18 to 70 years were evaluated. Width of aortic knob (AKW), straight length of aortic knob (AKS), curved length of aortic knob (AKC) and aortic knob index (AKI) were measured. Aortic knob index (AKI) was determined from AKC divided by AKS. Results: The mean aortic knob index (AKI) for male and female were 1.24±0.06 and 1.20±0.07 respectively and the total mean aortic knob index (AKI) was 1.22±0.07 in normal population. In hypertensive population, aortic knob index (AKI) was 1.49±0.095 and 1.42±0.04 in male and female respectively. Total aortic knob index (AKI) for hypertensive population was 1.45±0.083. Aortic knob index in hypertensive population was significantly higher than that of normal population. Mean aortic knob index (AKI) in male was significantly higher than that in female in both normal and hypertensive population (p<0.05). Conclusion: Aortic knob index (AKI), the index for aortic diameter, was higher in hypertensive population and male. Thus, simple measurement of aortic knob in PA chest x-ray may help in predicting cardiovascular disorder.
Size Matters! Impact of Age, Sex, Height, and Weight on the Normal Heart Size
Circulation: Cardiovascular Imaging, 2013
Background— Therapeutic decisions in cardiology are determined frequently by cardiac chamber size. To decide whether cardiac dimensions are still in the normal range, reliable reference values are needed. However, published reference values mostly refer to historical cohorts using motion-mode measurements and have not been adjusted for sex or age. The impact of body size was only vaguely addressed. The importance of such adjustments is illustrated by studies, which show that smaller individuals and women are at risk of delayed treatment and impaired outcome when currently used reference values are applied. The aim of the present study was to assess the impact of body size, sex, and age on the normal heart size. Methods and Results— We prospectively studied 622 individuals (52.7% women; 17–91 years; 143–200 cm; 32–240 kg) without cardiac disease by standard transthoracic echocardiography. Multivariable linear regression analyses of the impact of sex, age, height, and weight on cardia...

The heart is a muscular organ about the size of a closed fist that function by pumping blood throughout the body making the body size extremely important in its performance. Hence, the work done by the heart depend largely on the total body size of the individual, measurements of which depends on the weight and height to estimate BMI, BSA and BSI. The aim of the study was to establish Ghanaian based standard reference values of cardiothoracic ratio and determine the relationship with body parameters for clinical application. The maximum transverse diameter of the heart was obtained by adding the widest distance of the right heart border from the midline and the left heart border to the midline (cardiac diameter). This value was then divided by the maximum transverse diameter of the thorax (the thoracic diameter) to give the cardiothoracic ratio (CTR). Which is described as a ratio of the cardiac width as against thoracic width. The measured CTR was approximately 15: 33 (cm) and is therefore within the normal limit of 50%. This is because a CTR of greater than fifty percent is abnormal, in terms of Posterior - Anterior (PA) or an Anterior - Posterior (AP) view. In addition, the height and weight were measured to estimate the BMI, BSA and BSI and the relationship of these parameters with the measured cardiothoracic ratio. The result shows that BSI better correlate with the cardiothoracic ratio than any other body parameter with 92.53% accuracy rate. The determination of the CTR which represent the size of the normal heart is of the greatest importance to cardiologists. This is because the heart size enlargement is better assess by determining the ratio of size of the heart (cardiac diameter) as against the size of the chest wall (the thoracic diameter). This is use for initial assessment of heart condition by cardiologist, with a standard adult heart having a CTR value of 0.5. The study shows that a normal size is so variable and depends so greatly on the sex, age and body parameters of the study population. In conclusion, the study will serve as basis of the relationship between body parameter and the CTR. It also established that a deviation of heart size with BSI may reveal an underlying pathologic condition, and called for further studies to be conducted for clinical decision.

Nomograms to predict normal aortic root diameter for body surface area (BSA) in broad ranges of age have been widely used, but are limited by lack of consideration of gender effects, jumps in upper limits of aortic diameter between age strata, and data from older teenagers. Sinuses of Valsalva diameter was measured by American Society of Echocardiography convention in normal-weight, non-hypertensive, non-diabetic individuals ≥15 years old without aortic valve disease from clinical or population-based samples. Analyses of covariance and linear regression with assessment of residuals identified determinants and developed predictive models for normal aortic root diameter. Among 1,207 apparently normal individuals ≥15 years old (54% female), aortic root diameter was 2.1 to 4.3 cm. Aortic root diameter was strongly related to BSA and height (both r=0.48), age (r=0.36) and male gender (+2.7 mm adjusted for BSA and age) (all p<0.001). Multivariable equations using age, gender, and either BSA or height predicted aortic diameter strongly (both R=0.674, p <0.001) with minimal relation of residuals to age or body size: for BSA: 2.423+(age [yrs]*0.009) + (bsa [m 2 ]*0.461)-(sex [1=M, 2=F]*.267) SEE = 0.261 cm
Anatomical indicators of the heart and coronary arteries: An anthropometric study
Biomedical Research and Therapy, 2020
Introduction: Previous studies confirm that there is no anthropometric index of normal Iranian hearts, including diameter of cardiac valve, thickness of myocardial septum and coronary artery variation. The purpose of this study was to assess the anatomical indexes of the human heart and coronary artery in the Iranian population. Methods: The study was performed with 207 adult human hearts in both sexes (182 male and 25 female), fixed in 10% formaldehyde. Myocardial thickness and diameter of heart valves were measured using a Vernier caliper. Assessments of the coronary artery were carried out after removal of the pericardium. Results: Analysis of 207 cadaver coronary arteries showed left coronary artery (LCA) dominance type was present in 6.3% of corpus, and balance was present in 4.3% of corpus, while the largest number (89.4%) had right coronary artery (RCA) dominance. The mean values of the morphometric data are as follows: right atrial wall thickness (2.08 +/- 0.04 mm), left atr...
Assessment of the Cardiothoracic Ratio and Its Association with Gender and Age: A Nigerian Study
Galore International Journal of Health Sciences and Research
Cardiothoracic ratio (CTR) evaluation is a useful screening method used to detect cardiomegaly. It varies in different populations due to genetic, geographical and environmental factors that influence body morphology. This study aimed at assessing the CTR and determining its association with gender and age among adult Nigerians. This retrospective cross-sectional study was conducted in the Radiology Department of a Teaching Hospital in Delta State after obtaining ethical clearance. Postero-anterior chest radiographs of 200 adults (108 males and 92 females) were used to measure the transverse cardiac diameter (TCD) and transverse thoracic diameter (TTD) in centimeters (cm). These were used to compute the CTR (TCD/TTD*100). Statistical Package for Social Sciences version 22.0 was used to analyze the data. Independent t-test and analysis of variance (ANOVA) were used to determine the differences in the measurements with regards to gender and age-groups respectively. The correlation tha...

This study determined cardiac sizes, with the aid of chest radiographs, using the mean values of the CTR among adult Ijaws in Nigeria. Chest radiographs of 200 adult Ijaws were obtained and placed on a radiological illuminator box to reflect proper views of the radiographs, as cardiac and thoracic diameter values were collected. Data were analysed using SPSS for total number determination, mean, range, standard deviation and t-test value. The results recorded as follows; mean cardiac diameter for males is 13.44±1.10cm; that for female is 12.52±1.20cm and 12.98±1.19cm was recorded for both gender. For mean thoracic diameter, male value is 29.76 ± 1.85cm, that of female is 26.77±1.84cm and 28.26±2.37cm was recorded for both gender. Also the mean CTR (cardio-thoracic ratio) value was also recorded; the value for male is 45.22±3.19, that for female is 46.88±3.87 and 46.05±3.63 was recorded for both gender. Statistical analysis using student t-test showed that male adult Ijaws had higher value (p<0.05) in almost all the parameters except in CTR value, whereas females have higher CTR value (p<0.05). Findings of the index study (46.05 CTR values) provides a reference point for future studies on other Nigerian ethnic groups, which will in turn enhance better clinical interpretations necessary for diagnosing cardiovascular disorders.
