Rheumatic mitral stenosis (RMS) increases the risk of both atrial fibrillation (AF) and thromboembolism. Patients with mitral stenosis and normal sinus rhythm were enrolled in the study prospectively.The present study was designed to study whether echocardiographic evaluation in patients with mitral stenosis and normal sinus rhythm could predict the occurrence of symptomatic AF .
Sixty-two patients (51 females) with mitral stenosis and normal sinus rhythm were included in the study. Seven patients (11.3%) developed symptomatic AF and the remaining 55 were free of AF during a followed-up of 22±5 months. The following echocardiographic parameters were significantly increased and predicted the development of AF; left atrial (LA) mediolateral diameter (5.5 ± 0.5 cm vs 4.7 ± 0.7 cm), right atrial mediolateral diameter (4,7 ± 1.0 cm vs 3.6 ± 1.3 cm), LA area in the apical two chamber view ( 31 ± 3.2 cm2 vs 25 ± 5.8 cm2), right atrial volume (52 ± 22 cm3 vs 34 ± 19 cm3), and interatrial conduction time (IACT) (142 ± 22 msec vs 115 ± 16 msec). This study revealed that echocardiography can be used to predict symptomatic AF in patients with RMS and sinus rhythm.
风湿性二尖瓣狭窄（RMS）会增加心房颤动（AF）和血栓栓塞的风险。本研究前瞻性纳入了二尖瓣狭窄且窦性心律正常的患者。本研究旨在探讨二尖瓣狭窄且窦性心律正常患者的超声心动图评估能否预测有症状房颤的发生。
本研究纳入了62例（51例女性）二尖瓣狭窄且窦性心律正常的患者。在22±5个月的随访期间，7例患者（11.3%）发生了有症状房颤，其余55例未发生房颤。以下超声心动图参数显著升高并可预测房颤的发生；左心房（LA）中外径（5.5±0.5cm对4.7±0.7cm）、右心房中外径（4.7±1.0cm对3.6±1.3cm）、心尖两腔心切面LA面积（31±3.2cm²对25±5.8cm²）、右心房容积（52±22cm³对34±19cm³）以及房间传导时间（IACT）（142±22毫秒对115±16毫秒）。本研究表明，超声心动图可用于预测RMS和窦性心律患者的有症状房颤。
