UNUSUAL FORM OF TOTAL ANOMALOUS PULMONARY VENOUS CONNECTION WITH DOUBLE DRAINAGE

A patient with complex congenital heart disease was diagnosed by two-d imensional echocardiography. Total anomalous pulmonary venous connecti on (TAPVC) was suspected because of the results of two-dimensional ech ocardiography, but the exact anatomy was delineated by cineangiocardio graphy as an unusual form of TAPVC with double drainage or connections to the left superior vena cava at nearly the same level. The clinical implications and possible embryogenesis for such a condition are disc ussed.
