The Kawashima Operation With Simultaneous Preparation for Transcatheter Fontan-Kreutzer Completion.

Patients with functionally single ventricle and interrupted inferior vena cava may develop progressive cyanosis soon after the Kawashima operation. Therefore, early redirection of the hepatic venous return to the pulmonary circulation is recommended. To avoid performing an early redo sternotomy, we propose to prepare these patients for the interventional Fontan-Kreutzer at the time of the Kawashima operation using a technical modification of the approach reported by Prabhu and coworkers in 2017.

The matter of "unbalance" in right dominant atrioventricular septal defect.

Unbalance in atrioventricular septal defect can be found in more than one anatomic level and in different degrees at each level. The definition of "unbalance" has historically been focused in comparing the dimensions of main cardiac structures, such as the atrioventricular valve and the ventricles. However, the hemodynamic aspects of unbalance need to be considered as having, at least, similar relevance.
