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.
