Abstract
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). Conclusions: This study revealed that echocardiography can be used to predict symptomatic AF in patients with RMS and sinus rhythm.
