Factors affecting left ventricular remodeling after valve replacement for aortic stenosis. An overview

摘要: Although a small percentage of patients with critical aortic stenosis do not develop left ventricle hypertrophy, increased ventricular mass is widely observed in conditions afterload. There growing epidemiological evidence that hypertrophy associated excess cardiac mortality and morbidity only arterial hypertension, but also those undergoing valve replacement. Valve replacement surgery relieves the obstruction prolongs life many patients, favorable or adverse remodeling affected by large number factors whose specific roles are still subject debate. Age, gender, hemodynamic factors, prosthetic types, myocyte alterations, interstitial structures, blood pressure control ethnicity can all influence process regression, myocardial metabolism coronary artery circulation involved changes occurring after The aim this overview to analyze these light our experience, elucidate important question prosthesis-patient mismatch considering method effective orifice area, discuss surgical timings techniques improve management maximize probability regression.
