Total anomalous pulmonary venous connection: mixed variation [2(1/2) + 1(1/2)] type: Bizarre Pattern: a case report

Among all variants of total anomalous pulmonary venous connection, mixed variety is a rare congenital anomaly. It comprises 3 different patterns including 2+2, 3+1, bizarre variations. These bizarre variations are uncommon findings in mixed variety. In this particular case, we report surgical correction of such rare variation comprising [2(1/2) cardiac + 1(1/2) supracardiac] type of pulmonary venous drainage. These variations impose the importance of preoperative delineation of heterogeneous venous drainage and subsequent planning for surgical repair.
