Association of atrial septal defect with Poland-Moebius syndrome: vascular disruption can be a common etiologic factor. A case report.

The authors describe an association of atrial septal defect with partial symptoms of the Poland-Moebius syndrome. Both are thought to be caused by developmental disorders of the mesenchyme and ectodermal derivatives. This anomalous association can be accepted as one concept of the subclavian artery blood supply disruption sequence during embryo-genesis.
