A MODERN VIEW ON THE CLASSIFICATION AND DIAGNOSIS OF THE OPEN ARTERIAL DUCT (REVIEW)

We have analyzed domestic and foreign sources, on the basis of which a variant of systematization of the existing author’s classifications of the patent arterial duct (PAD) is proposed and the main diagnostic studies used to identify a functioning duct are described. Mandatory diagnostic measures for suspected PAD include assessment of the clinical picture (subjective and objective examination data) as well as non-invasive methods (radiography, electrocardiography, echocardiography, including three-dimensional variant, multispiral computed tomography (MCT), perfusion
index, and infrared spectroscopy). The important role of laboratory diagnostic methods was noted: it was shown that the level of plasma B-type natriuretic peptide (NT-proBNP) and the level of cardiac troponin T (cTnT) can be used as biomarkers indicating the presence of PAD and allowing the determination of treatment approaches.
