Abstract

Ebstein's anomaly (EA) involves a displaced and dysplastic tricuspid valve resulting in an atrialized portion of the right ventricle and an enlargement of the functional right ventricle and right atrium. Biomarkers targeting heart failure such as brain natriuretic peptide (BNP) or haematological parameters [haemoglobin (Hb) and haematocrit (Hct)] are upregulated in states of pulmonary hypoperfusion. We hypothesized that decreased pulmonary perfusion dependent on the stage of right heart failure is a possible mechanism in EA, and that it can be correlated with cardiac magnetic resonance (CMR) parameters. The aim of this study was to investigate the relationship between BNP and haematological parameters with functional parameters from CMR and exercise testing in patients with EA. Twenty-five patients with non-corrected EA were studied prospectively (mean age 26 ± 14 years). BNP level was increased (74 ± 127 ng/L), and in 16% markedly above the heart failure cut-off level of 100 ng/L. Hb and Hct were increased above normal levels in 20 and 24% of patients, respectively. BNP and Hct/Hb correlated with CMR [total right/left (R/L)-Volume-Index, right atrium-end-diastolic volume index (EDVi), functional right ventricle (fRV)-EDVi, fRV...Continue Reading
