无典型舒张期隆隆样杂音的二尖瓣狭窄称“哑型”二尖瓣狭窄(“Silent”Mitral Stenosis),临床上常易误诊或漏诊。1976年7月～1980年6月五年中我院收治风湿性心脏病二尖瓣狭窄122例,其中“哑型”4例,2例入院时误诊。本文摘要报告病例并结合有关文献重点讨论“哑型”二尖瓣狭窄的诊断。病例摘要(见附表) Mitral stenosis without typical diastolic rumbling noise is called “dull” mitral stenosis (“Silent” Mitral Stenosis) and is often clinically misdiagnosed or missed. From July 1976 to June 1980, 122 cases of rheumatic mitral stenosis were admitted to our hospital. Among them, 4 cases were “dumb type” and 2 cases were misdiagnosed on admission. This article summarizes the reported cases and in combination with relevant literature focuses on the diagnosis of “dull” mitral stenosis. Case Summary (see attached table)
