Abstract:
701 cardiac valve replacements were performed between 1982-198 7 by our Cardiac Team in four countries 639 in Saudi Arabia. 27 in Yemen. 30 in Mauritius and 5 in Sudan. There were 398 aortic valve replacements (AVR). 326 patients received mechanical aortic valves and 72 bovine aortic valves. 417 patients underwent mitral valve replacements (MVR). 176 received bovine mitral pericardial valves and 24 mechanical mitral valves. Both AVR and MVR groups included 114 double valve replacement (AVR and MVR). 38 patients died perioperatively (average mortality rate of 5.4%). Prosthetic valve endocarditis of early onset occurred in 11 patients. Paravalvular leak in 4 patients (0.5%), thromboembolic episodes in 4 patients with AVR (1%) and in 8 patients with MVR (2%), acute catastrophic thrombosis in 3 patients with AVR (0.7%) and 2 patients with MVR (0.4%). Valve dysfunction occurred in 18 patients (2.5%) of which 9 had bio prosthetic and 3 mechanical valves. The choice of valve prostheses depended on a multifactorial scheme including age sex, origin, and feasibility of anticoagulation, LV size, psychological makeup and intelligence of the patient respectively, awareness, literacy and availability of laboratories to estimate Prothrombin time. The choice of a cardiac prostheses for the patients in developing countries is a difficult but challenging and rewarding task.
