Significant ventricular dysfunction was defined as moderate or worse ventricular dysfunction on pre-cardiac catheterization echocardiography or evidence of hemodynamic compromise (i.e., ventricular end-diastolic pressure >=14 mm Hg and/or calculated cardiac index <2.6 l/min/m2). Recently, the Pediatric Heart Network (PHN), a consortium of 15 North American medical centers focused on the treatment of congenital heart disease, reported the results of a randomized clinical trial designed to compare shunt types after the NP for single-ventricle lesions (3). [...]between stage II discharge and 12 months of age, an additional 6.8% of the RVPA shunt patients required interventions, while 4% of the MBT shunt patients required interventions.
