Synonym: atrial septal defect with mitral stenosis syndrome
The definition has changed and continued to vary. Lutembacher's syndrome is sometimes stated as referring to a congenital atrial septal defect (ASD) complicated by acquired mitral stenosis. A different definition used is any combination of ASD (congenital or iatrogenic) and MS (congenital or acquired). With percutaneous balloon mitral valvuloplasty for acquired MS, residual iatrogenic ASD secondary to trans-septal puncture is more common than congenital ASD.
