Abstract

This study aims to evaluate the prevalence of significant coronary artery disease (CAD) in patients with severe valvular heart disease (VHD), and the association between these two cardiac entities. Methods: A retrospective study was conducted on 100 consecutive patients who underwent surgery for severe VHD in the cardiovascular department of Ibn Sina University Hospital if Rabat, between December 2020 and December 2022. According to transthoracic echocardiography, patients were divided into 4 groups: patients with severe aortic stenosis (AS), patients with severe aortic regurgitation (AR), patients with severe mitral stenosis (MS), and patients with severe mitral regurgitation (MR). Preoperative coronary angiographies were reviewed for the presence or the absence of significant CAD. Results: Of the 120 patients with severe VHD, 43 patients had isolated aortic valve disease, 57 patients had isolated mitral valve disease, and 20 patients had combined aortomitral valve disease. CAD was detected in 34.16% of all patients with severe VHD, in 48% of patients with isolated aortic valve disease, and in 8% of patients with isolated mitral valve disease. Statistical analysis showed a higher prevalence in patients with severe aortic valve stenosis and a significant relationship between CAD and aortic valve disease, mainly in AS. Conclusion: The prevalence of CAD in patients with VHD is 34%, and it correlates significantly with aortic valve disease, in particular with severe AS.
