초록
노령 인구의 기대 수명이 증가함에 따라 퇴행성 판막 질환이 많아지고 있다. 류마티스성 판막 질환인 승모판 협착증과 대동맥판 역류가 점차적으로 감소하고 석회화된 퇴행성 대동맥판 협착증, 승모판 탈출증 및 허혈성 심장 질환으로 인한 승모판막 폐쇄 부전의 빈도가 증가하고 있다. 심장초음파는 심장판막질환의 진단은 물론, 치료방법 및 수술 시기와 더불어 예후 평가에서도 매우 중요한 도구이며, 판막질환을 평가할 때 모든 판막을 자세하게 관찰하는 이면성 심장초음파가 우선해야 한다. 흔히 접하는 퇴행성 판막질환에 대한 이해와 함께 임상적 특성을 파악하여 심장초음파를 정확하게 시행하는 것이 가장 중요하다. 아울러 대동맥판 협착증의 중증도 평가가 수술적 적응증을 판단하는 데 꼭 필요한 검사인만큼 정확한 판단 기준에 따라 평가하여 환자의 정확한 진단 및 치료가 이루어지도록 해야 한다. 퇴행성 대동맥판 협착증 환자 3례를 통해 심장초음파 검사의 중증도 평가를 쉽게 이해할 수 있기를 바라며 퇴행성 판막 질환의 심초음파 소견을 숙지하는 것이 심장초음파검사를 정확하게 수행하는 것에 수반되어야할 것으로 사료된다.
Abstract
The incidence of degenerative valve disease also increasing with the increasing life expectancy of the elderly population. Rheumatic valve disease is decreasing gradually and the incidence of calcified degenerative aortic stenosis (AS) is growing. Echocardiography is a very important tool for evaluating the prognosis and treatment method as well as the time of operation and diagnosis of heart valve disease. When evaluating valvular heart disease, 2-dimensional echocardiography, which observes all heart valves in detail, should take precedence. Understanding the clinical findings of degenerative valve disease and performing precise echocardiography are extremely important. In addition, an assessment of the severity of aortic stenosis is necessary to determine the surgical indications. An assessment of the severity by echocardiography was explained with three cases of degenerative aortic stenosis. To perform echocardiography accurately, it is necessary to understand degenerative valve disease and its clinical findings accurately.
