Prevalence of Aortic and Mitral Valves Calcification in Patients with Coronary Artery Disease Detected by Computed Tomography Angiography..

Abstract

Background: The risks of coronary artery disease and valvular heart disease are identical. Consequently, it is possible for CT scans to mistakenly indicate valvular heart disease. CT angiography is a common first test for those who could have coronary artery disease. So, CT angiography can show incidental valvular calcification, which could be very important for screening and figuring out risk. Aim of the Study: The aim is to detect the prevalence of aortic and mitral valve calcification among patients suspected of having coronary artery disease, and to study the correlation between calcification and various risk factors and clinical implications. Methodology: prospective cross-sectional study, included 340 patients  were referred to Al-Sader Medical City/Al-Najaf Al-Ashraf, Iraq's Al-Najaf Center of Cardiac Surgery and Catheterization, all patients underwent  calcium scoring and coronary CT angiography. Results :Aortic valve calcification was found in 32 patients (11.2%) while mitral valve calcification was  found in 4 patients (1.2%), Aortic valve calcification was statistically correlated to other cardiovascular risk factors including advanced age (p<0.001), male gender(p<0.001),obesity(p=0.017), hypertension(p<0.001), diabetes(p=0.028), hyperlipidemia(p=0.028), smoking(p=0.003), history of IHD(p=0.013), calcification severity is positively related to coronary artery calcium score (p<0.001). Conclusions: Aortic and mitral valve calcification was observed in 12.4% of patients undergoing CCTA, and this was found to be associated with concomitant coronary atherosclerosis (P < 0.001)..
