Abstract
Although the Cone procedure has improved outcomes for patients with Ebstein´s anomaly (EA), neither RV systolic func-
tion recovery in long-term follow-up nor the best echocardiographic parameters to assess RV function are well established.
Thus, we evaluated RV performance after the Cone procedure comparing two-dimensional (2DEcho) and three-dimensional
(3DEcho) echocardiography to cardiac magnetic resonance (CMR). We assessed 27 EA patients after the Cone procedure
(53% female, median age of 20 years at the procedure, median post-operative follow-up duration of 8 years). Echocardiog-
raphy was performed 4 h apart from the CMR. RV global longitudinal strain (GLS), fractional area change (FAC), tricuspid
annular plane systolic excursion (TAPSE), myocardial performance index and tissue Doppler S’ velocity were assessed using
2DEcho, whereas 3DEcho was used to evaluate RV volumes and ejection fraction (RVEF). Echocardiographic variables were
compared to CMR-RVEF. All patients were in the NYHA functional class I. Median TAPSE was 15.9 mm, FAC 30.2%, and
RV-GLS -15%; median RVEF by 3DEcho was 31.9% and 43% by CMR. Among 2DEcho parameters, RV-GLS and FAC had
a substantial correlation with CMR-RVEF (r = − 0.63 and r = 0.55, respectively); from 3DEcho, the indexed RV volumes and
RVEF were closely correlated with CMR (RV-EDVi, r = 0.60, RV-ESVi, r = 0.72; and RVEF r = 0.60). RV systolic function is
impaired years after the Cone procedure, despite a good clinical status. FAC and RV-GLS are useful 2DEcho tools to assess
RV function in these patients; however, 3DEcho measurements appear to provide a better RV assessment.

Introduction
Ebstein’s anomaly (EA) is characterized by a failure in
the delamination of the tricuspid valve leafets from the
adjacent myocardium, resulting in various degrees of tri-
cuspid valve abnormalities. The myocardium is invariably
abnormal in EA, characterized by the so-called myopa-
thy of the right ventricle (RV) [1–3]. There is evidence
to support that RV dysfunction is present in EA patients
