Feasibility of Computed Tomography Coronary Angiography in Diagnosing Left Ventricle Dysfunction in Patients with Aortic stenosis

Aortic stenosis (AS) is a pathological condition in which the aortic valve which is present between the left ventricle and aorta becomes narrowed. Patients with AS had a high mortality rate due to left ventricular dysfunction which leads to improper blood supply to the body and associated coronary artery disease. Echocardiography is the modality to evaluate cardiac disease. Patients refer to further modalities for confirmation of disease or preoperative evaluation. The objective of this study is to investigate the feasibility of f coronary angiography (CTCA) in diagnosing left ventricle dysfunction in patients with AS. This cross-sectional descriptive study was conducted at Punjab Institute of Cardiology, Lahore. Sample size of our research was 40. The participants ranged in age from 17 to 73 years (72.5%male), with most of the patients were of the age between 21 to 40 years. 12.5% of those aged over 65 while 87.5% were between 17 to 64 years affected with AS. 9(22.5%) patients had congenital bicuspid aortic valve causing AS while 31(77.5%) had trileaflet aortic valve which acquire AS. 13(32.5%) patients out of 40 had left ventricle ejection fraction (LVEF) < 50% out of which 6(46.2%) patients had dilated LV with moderate Left ventricle (LV) systolic dysfunction and 7(53.8) patients had dilated LV with severe LV systolic dysfunction were diagnosed on CTCA. CTCA is more feasible for early and accurate diagnosis of left ventricular dysfunction in AS patients. CTCA can improve the diagnostic potential and treatment plans for patients with AS and associated left ventricular dysfunction.
