Intervenção clínica e cirúrgica na estenose da válvula aórtica, quais as indicações?

Abstract

Among the alterations in aortic valves is Aortic Valve Stenosis or Aortic Stenosis, characterized by the defect of narrowing of the valve structures, associated or not with the fusion of the aortic valve leaflets. This valve narrowing makes it difficult to properly empty the left ventricle, favoring the development of ventricular hypertrophy due to chronic and progressive overload of the ventricle, with a consequent reduction in blood supply to the heart muscle and other tissues. The prevalence of severe aortic stenosis has increased due to an aging population. Therefore, this research aims to expose how aortic stenosis occurs and its progression, in addition to the clinical and surgical intervention of this pathology. This is a bibliographical study, to perform the search, combinations were used between the following keywords, considered as descriptors in DeCS (descriptors and health sciences) Cardiovascular Surgical Procedures, Aortic Valve Stenosis and Aortic Valve. Aortic stenosis, depending on the symptoms and severity of the stratification, can be clinically supported with medications such as statins, antihypertensives and bisphosphanates, as well as direct surgical approach.
