In this Journal Club, Ben and Daphna dig into two new papers on PDA management in our smallest patients. First, the SMART-PDA pilot RCT from Souvik Mitra and colleagues, which uses comprehensive hemodynamic screening to selectively treat high-volume shunts in infants born before 26 weeks, and whose striking Bayesian signal for reduced pulmonary hemorrhage and NEC stopped the trial early. Then a companion JAMA Network Open comparative effectiveness study across four pharmacotherapy regimens. Along the way, Ben shares hemodynamics pearls from his Montreal training: why left ventricular output, LA:Ao ratio, and transductal velocity matter more than PDA diameter alone.
