Subtotal cor triatriatum with left partial anomalous pulmonary venous return. Successful surgical repair in an infant
RB Jennings Jr and BJ Innes
A 10-week-old infant underwent successful repair of subtotal cor
triatriatum associated with left-sided partial anomalous pulmonary venous
return to the innominate vein. This unusual type of cor triatriatum
represents an intermediate embryologic form between pure cor triatriatum
and total anomalous pulmonary venous return. Important hemodynamic
differences exist between this defect and pure cor triatriatum. Exact
anatomic diagnosis prior to operation is highly desirable. To our
knowledge, this case represents the first successful repair of this very
rare congenital cardiac defect.
