Erratum to: Pediatr Cardiol DOI 10.1007/s00246-014-1009-0

Unfortunately there are two errors in the original version of this article:

  1. 1.

    The description for measuring the mitral valve annulus (at end diastole) in both the manuscript and in the legend for Fig. 4 is incorrect; in addition, Fig. 4a, showing how the mitral valve should be measured, is incorrect.

The correct way to measure the mitral valve is as follows:

The mitral valve annulus (MV4C) should be measured (in cm) in the apical 4-chamber (4C) imaging plane from hinge point to hinge point at full leaflet excursion in diastole. This is shown in the accompanying figure.

Echocardiographic measurements (in cm) used in the calculation of the 2V Score. a The MV is measured in the 4C imaging plane from hinge point to hinge point at full leaflet excursion in diastole. b The AV is measured in the parasternal long axis (PSLA) imaging plane in mid systole. c and d The LV and RV length are measured from the annular plane to the ventricular apex in the 4C imaging plane at end diastole. The main pulmonary artery is measured at mid systole in either the parasternal short axis (e) or the PSLA (f) imaging plane

  1. 2.

    The original version of this article states that “A non-apex forming LV was seen in 7 (41 %) of those undergoing successful 2V repair.” which is incorrect. The correct statement should read, “A non-apex forming LV was seen in 10 (59 %) of those undergoing successful 2V repair.”
