心脏黏液瘤的临床及超声特点探讨

目的探讨心脏黏液瘤的临床及超声特点。方法选取11例心脏黏液瘤患者,男5例、女6例,行多普勒超声检查,均经手术和病理证实,分析患者的临床特点及超声特点。结果 11例患者的临床表现包括胸闷、心悸、发热、晕厥、脑梗死、心律失常等,体征包括舒张期杂音、双期杂音、肿瘤扑落音等。11例患者均为单发,左房多见,超声表现为心房内稍高回声团块,边界清晰,部分呈分叶状,大部分内部回声较均匀,多数瘤体有蒂附着于房间隔上,随心动周期规律摆动,同时并发心房增大,下腔静脉增宽等。结论心脏黏液瘤临床表现个体差异极大,但超声表现较为典型,可以作为该病的首选检查方式。

Study on the clinical and ultrasonic features of cardiac myxoma

Objective To explore the clinical and echocardiographic features of atrial myxoma .Methods Eleven patients(6 fe‐male ,7 male) with atrial myxoma were included in the study .They all received echocardiography examination and the results were confirmed by pathological examination .Results The clinical manifestation included chest distress ,palpitation ,fever ,syncope ,cere‐bral infarction and arrhythmia .Physical signs included diastolic murmur ,systolic and diastolic murmurs and tumor plop .The atrial myxomas were all single tumor and mostly in left atrium .Ultrasonography features of atrial myxoma were slightly hyperechoic mass in atrium ,clear boundary ,lobulated part ,uniform internal echo .Most tumors have a pedicle attached to the atrial septum ,with the cardiac cycle swing ,concomitant with atrial enlargement and inferior vena cava widened .Conclusion Individual difference in clinical manifestations of atrial myxoma is great ,but the ultrasonic manifestation is typical .As the first examination ,ultrasound can be used as the preferred examination of the disease .
