ABSTRACTIntroduction: the physiological atrial correction surgery allows extending the life expectancy of those people who are born with transposition of the great arteries. The right ventricular dysfunction evolves in gradual phases. In the course of time, the transthoracic echocardiograpy proves the existence of right ventricle dysfunction since the subclinical stage.
Objective: to determine the clinical significance of echocardiographic mensurations performed in patients suffering this heart disease.
Methods: prospective, observational and cross-sectional of 90 patients in the "William Soler" pediatric cardiocenter from 2011 to 2014. An effectiency study was made involving the analysis of the incidence and the prevalence rates of the event called clinical dysfunction of the systemic right ventricule at each echocardiographic measurement taken.
Results: there are echocardiographic measures with clinical significance for the prediction of the systemic right ventricule dysfunction since the subclinical phase.
Conclusions: the mensurations of the telediastolic diameter and the parietal thickness of the right ventricle, the time-dependent pressure derivate and the characterization of the tricuspid failure show clinical significance and agreement with the standards of the summary and inferential statistic
