Anesthesia Management for Asymptomatic Aortic Narrowing

Abstract

Calcified aortic stenosis (AOR) is the most common valve disease indeveloped countries and its prevalence is constantly increasingreaching 2.8% of patients over 75 years old which represents a realpublic health problem due to the aging of the population [1]. Theclassic symptoms of severe RAo (angina, dyspnea and syncope)occur at an advanced stage of the disease [2].In these elderly patients, the diagnosis and care are sometimes delayed. The symptomatology is difficult to assess in patients who are oftenphysically limited, by age and the presence of associated comorbidfactors. This population, so-called asymptomatic, is composed,in half of the cases, of patients “False asymptomatic”; it must be unmasked by a stress test if this is possible and by the dosage of biomarkers, in order not to not ignore a low noise RAC which couldhave benefited from treatment surgical [3-6]. These little-knownpatients will progress slowly towards the cardiac decompensation.
