One and a Half Ventricle Repair in Adults: Postoperative Hemodynamic Assessment Using Phase-Contrast Magnetic Resonance Imaging

After 1½ repair, right ventricular volume unloading was effective in all patients, but intercaval collateral veins (ie. QSVC/QUC < 1) appeared to develop in most of the patients. Furthermore blood flow to the upper compartment of the body appeared to diminish, presumably due to postoperative elevation of central venous pressure.
