Modified T-shaped left atrium incision in the bi-atrial approach for infracardiac type TAPVR repair

The bi-atrial approach "in-situ" technique of vertical confluence to the left atrial repair avoids the risks of anastomosis site kinking and twisting for infracardiac-type total anomalous pulmonary venous connection reconstruction, but how to obtain the adequate left atrial orifice size is an important issue. Herein, we describe our vertical confluence vein flap with the modified T-shaped left atrium incision technique in managing those patients with infracardiac type total anomalous primary venous reconstruction.
