How could right ventricular outflow tract stenting be made into one of the many small steps on the long road to solid evidence of rehabilitation of pulmonary arteries?

摘要

In their contribution, Barron et al. [1] draw the conclusion that P mary stenting of the right ventricular outflow tract (RVOT) facilitates staged palliation for tetralogy of Fallot in small infants and complex anatomy. The manuscript claims that improved pulmonary arterial blood flow generated by the stent leads to growth of the branch pulmonary arteries and may improve the substrate for subsequent surgical repair [1]. Such a repair is reported to be safe but requiring a transannular patch in a ma-jority[1]. This all sounds fine, but the question can be raised, whether a correct perspective of analysis is being taken.
