自超声心动图广泛应用以来,成人二尖瓣脱垂病例已有不少报导,但小儿二尖瓣脱垂却甚为少见。现报导我院所见小儿二尖瓣脱垂5例如下。讨论:二尖瓣脱垂可发生于各个不同的年龄,但小儿的发生率远较成人为低,仅1.4％。该病可分原发性与继发性两种。本文例5未能查出病因属原发性。其余4例属继发性,系风湿热致心内膜炎引起。本病症状常有疲乏,气急、心悸、面色苍白、晕厥及心力衰竭等。据报导约20％病人无特殊症状,于体检时闻及杂音, 由超声心动图确诊。一般小儿原发性二尖瓣脱垂多无症状,但至成年才逐渐发生,可能与二尖瓣粘液瘤病变性呈进行发展有关。本病体征主要为收缩早期喀喇音,收缩中期杂音,或
Since the widespread use of echocardiography, adult mitral valve prolapse cases have been reported, but pediatric mitral valve prolapse is rare. Now reported in our hospital seen in children with mitral valve prolapse in 5 cases as follows. Discussion: Mitral valve prolapse can occur at all different ages, but the incidence of children is far lower than that of adults, with only 1.4%. The disease can be divided into two primary and secondary. Example 5 failed to detect the etiology is primary. The remaining 4 cases are secondary to rheumatic fever caused by endocarditis. Symptoms of the disease often fatigue, shortness of breath, palpitations, pale, fainting and heart failure. About 20% of the patients reported to have no specific symptoms were reported to have heard noise at the time of the physical examination and confirmed by echocardiography. In general, asymptomatic primary mitral valve prolapse in children, but only gradually occurred in adulthood, may be associated with the development of mitral myxoma degeneration. Symptoms of the disease mainly contractions early Kara tone, contraction of mid-murmur, or
