INTRODUCTION
The most common cause of left atrial dilatation is rheumatoid mitral valve disease. Giant left atrium (GLA) is used for atrium with a diameter of 6.5 cm and larger [1]. Massive expansion of cardiac structures can cause compression symptoms such as dysphagia, dysphonia, or Ortner syndrome. The most common indication of left atrial volume reduction plasty during mitral valve surgery is compression symptoms [2]. The choice of left atrial reduction technique should consider factors such as the patient’s comorbidities, major bleeding risk, or prolongation of cardiopulmonary bypass time.
