Objective: The aims of the study was to find the prevalence of CAD in RHD patients undergoing preoperative coronary angiogram and its

distribution in various valvular lesions

Materials and Methods: RHD patients who underwent CAG before surgery from 2017–2018 were evaluated. Patients of RHD with significant

CAD (≥50% stenosis) were studied. Patients with acute coronary artery syndrome due to emboli were excluded.

Results: There were 101 RHD patients who underwent preoperative CAG from 2017–2018. Mean age of the population was 46.7years. Majority

of the patients had normal epicardial coronaries on CAG. Among these 101 RHD patients, 23 (22%) patients had significant coronary artery disease

(males–14, females – 9). Single vessel disease in 15 patients (males–8, females–7), double vessel disease in 3 patients, left main with double vessel

disease in 2 patients, triple vessel disease in 2 patients, anomalous coronary artery was found in one patient (right coronary artery). Predominant

aortic stenosis and multivalvular disease had majority of coronary artery disease.

Conclusion: The prevalence of CAD in patients with RHD is similar to other studies. Males had more CAD compared to females. Single–vessel

involvement is more common among these patients. Predominant aortic stenosis and multivalvular disease had majority of coronary artery disease.

It is indicated to undergo preoperative CAG before valve surgery when age is more than 40years.
