Abstract Objective: There is no consensus on the definition of a hemodynamically significant
patent ductus arteriosus (hsPDA). In this review article, our objective is to discuss the
main variables that one should consider when determining the hemodynamic signifi‐
cance of a PDA.
Results: We describe the various approaches that have been utilized over time to
define an hsPDA and discuss the strengths and weaknesses of each echocardio‐
graphic index. Finally, we propose a comprehensive and individualized approach in
determining the hemodynamic significance of the PDA.
Conclusion: There are several PDA‐related clinical, echocardiographic, and other ob‐
jective variables to take into consideration… More >
