[Percutaneous treatment of Lutembacher syndrome: a case report].

: Lutembacher syndrome is a rare combination of congenital atrial septal defect (ASD) and acquired mitral stenosis (MS). Although it is traditionally corrected by surgical treatment, both conditions are amenable to transcatheter treatment without the need for surgery. We present a 49-year-old woman with Lutembacher syndrome. On pretreatment transthoracic echocardiography, planimetric mitral valve area was 1.5 cm(2), maximum diastolic gradient was 17 mmHg, and mean diastolic gradient was 9 mmHg. Combined percutaneous treatment was performed including balloon valvuloplasty for MS and closure of the ASD with the Amplatzer septal occluder. The patient was discharged uneventfully. Transthoracic echocardiography performed a week later showed planimetric mitral valve area as 2.1 cm(2), maximum diastolic gradient as 9 mmHg, and mean diastolic gradient as 4 mmHg. Complete closure of the ASD was achieved. Transcatheter treatment may be an effective alternative to surgery in selected patients with Lutembacher syndrome.
