Available from: Īortic diameter at various levels has been documented in Caucasian but because of the paucity of such study in Africa, their values are used as reference. The relationship between infrarenal and suprarenal transverse aortic diameter on ultrasound among adults in Zaria, Nigeria. How to cite this URL: Usman BO, Ibinaiye PO, Abdulaziz U, Inah GB.

Keywords: Body mass index, infrarenal aortic diameter, suprarenal aortic diameter These values would be of help to radiologists, surgeons, and other clinician in the diagnosis, management, and follow-up of cardiovascular patients. SAD, IAD/SAD ratio, age and body mass index were also independent predictors of IAD.Ĭonclusion: This study has established the normal ratio values of infrarenal to suprarenal transverse aortic diameter in healthy adults and the factors that correlate with transverse aortic diameter, as well as independent predictors of transverse aortic diameter in Zaria. IAD, IAD/SAD ratio, and weight were independent predictors of SAD on multilinear regression analysis. The mean ratio of infra- and supra-renal diameter was 0.91 (☐.04), in male subjects, it was 0.92 (☐.04) and in female subjects, it was 0.90 (☐.05). The mean infrarenal aortic diameter (IAD) was 1.63 ± 0.23 cm with a range of 1.01-2.46 cm. Results: The mean suprarenal aortic diameter (SAD) of the subjects was 1.79 ± 0.25 cm with a range of 1.15-2.61 cm. Routine protocol for scanning the abdomen in the transverse, longitudinal and craniocaudal planes were used to scan the aorta for supra- and infrarenal dimensions. Patients and Methods: Three hundred consecutive Nigerian adults without CVD attending ultrasound unit of Radiology Department of Ahmadu Bello University Teaching Hospital, Zaria, were recruited for this study. The objective of this study was to determine the normal value of infrarenal and suprarenal transverse aortic diameter and their relationship on ultrasound among adults in Zaria, Nigeria Measurement of aortic diameters can help in predicting CVD in patients. I hope that helps Emma (and all of us) learn a little more about aortic stenosis and aortic valve size.Background: Cardiovascular disease (CVD) is now a public health problem due to its high prevalence and associated high morbidity and mortality. If you are curious, here is a picture of a normal aortic valve:Īnd, here is a picture of a stenotic aortic valve that is bicuspid with calcified leaflets: If the valve area is between 1.5 and 2.0 cm2, the stenosis is mild if the valve area is between 1.0 and 1.5 cm2, the stenosis is moderate if the valve area is between 0.6 and 1.0 cm2, the stenosis is moderate-severe areas of less than 0.6 cm2 constitute severe aortic stenosis. Specific to size, a normal aortic valve area is >2 centimeters squared (cm2). As shown, the severity of aortic stenosis can result from three criteria - valve area (size), aortic velocity and aortic valve gradient. To help Emma, please see the chart above which contains the American College of Cardiology (ACC) and the American Heart Association (AHA) guidelines for aortic stenosis. Bad Bedside Manner) that I needed heart valve replacement surgery. ![]() Like Emma, I had this exact question when I was told by my first cardiologist (aka Dr. ![]()
