Scimitar syndrome

Semin Thorac Cardiovasc Surg Pediatr Card Surg Annu. 2006:56-62. doi: 10.1053/j.pcsu.2006.02.011.


Scimitar syndrome is a rare congenital anomaly consisting in part of right pulmonary venous return to the inferior vena cava. There is a clear bimodal presentation of this syndrome with either an infantile manifestation or a pediatric/adult form. The infantile variant is marked by a higher incidence and severity of associated defects, heart failure, pulmonary hypertension, and significant mortality. The patient with the pediatric/adult form is less severely affected and may be asymptomatic on diagnosis. In this article, we review the historical aspects, presentation, and pathophysiology of Scimitar syndrome and discuss available treatment strategies. We emphasize the safe and effective approach developed at Indiana University that obviates both the need for an intra-atrial baffle or use of cardiopulmonary bypass. The results with our alternative approach to Scimitar syndrome are summarized and they compare favorably with other published reports.
