Successful surgical correction of a single atrium associated with cleft mitral valve persistent left superior vena cava and pulmonary valvular stenosis as an isolated cardiac defect.

Single atrium (SA) is a complex cardiac anomaly and generally a component of certain congenital syndromes. It is extremely rare for SA to be observed as an isolated defect. We report here a 13-year-old male patient with SA as an isolated cardiac defect, successfully corrected by surgery.
