AGUILAR-SEGURA, Perla Roxana et al. Correlation between magnetic resonance and transthoracic echocardiogram for the assessment of pulmonary insufficiency in pediatric patients with congenital heart disease. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.4, pp.334-339. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.10.010.

Motivation: To establish the correlation and concordance of the degree of severity of pulmonary insufficiency between echocardiography and magnetic resonance in pediatric population of a third level hospital. Methods: 20 patients diagnosed with congenital heart disease and with pulmonary insufficiency were studied, they underwent a transthoracic echocardiogram and a magnetic resonance. The relationship of the vena contracta, the pulmonary regurgitation jet, the pressure half-time time, the presence of reversed end-diastolic flow and the pulmonary insufficiency index were calculated. With regards to the magnetic resonance, both fraction and regurgitant volume were measured. An analysis of the correlation was conducted.by means of the Spearman correlation and the Tau B. Results: Corrected Fallot's tetralogy represented 60% of the sample. The correlation was significant in the fraction and the regurgitant volume of the magnetic resonance, as well as in the echocardiographic variables of M-mode pulmonary insufficiency, vena contracta and vena contracta/pulmonary artery percentage. The correlation between the degrees of pulmonary insufficiency by magnetic resonance and echocardiogram was 0.85 (p < 0.001). Conclusions: Vena contracta and the VC/PA percentage are variables that present high correlation with the fraction and the regurgitant volume of nuclear magnetic resonance to assess pulmonary insufficiency in patients after a congenital cardiac disease surgery.
