Lutembacher syndrome is a combination of congenital atrial septal defect (ASD) and acquired mitral stenosis (MS). The combination of these 2 diseases has hemodynamic influences on each other and the degree of MS may be underestimated. Traditionally, Lutembacher syndrome is corrected by surgical treatment. Nowadays, these 2 diseases are amenable to transcatheter treatment without the need for surgery. Here, we describe a 28-year-old female with Lutembacher syndrome who benefited from combined transcatheter therapy of balloon valvuloplasty for MS and device closure for ASD with an Amplatzer septal occluder.
