7.1.4 Study findings

7.1.4.1 Newly diagnosed VHD

Of 4,005 de novo presentations to the Cardiology Unit of the Chris Hani Baragwanath Hospital during the study period, 960 (24.0%) had a valvular abnormality. Affected patients were predominantly of African ancestry (n = 868 [90.4%]), women (n = 570 [59.4%]), and long-term residents of Soweto (n = 512 [53.3%]). Overall, there was an equal balance between structural VHD (n = 481 [50.1%]), and functional VHD (n = 439 [45.7%]). As shown in Table 7.1, the most common structural valve disease presented was RHD, found in 344 (71.5%) patients. Other structural abnormalities included CHD (n = 20; 55.6%), mitral valve prolapse (n = 5; 13.9%), myxomatous mitral valve (n = 3; 8.3%), submitral aneurysm (n = 2; 5.6%), Marfan syndrome (n = 1; 2.8%), subaortic aneurysm (n = 12.8%), hypertrophic CMO (n = 1; 2.8%), and unclassified (n = 3; 8.3%).
