Table 2 Comparison of patients with early surgical breakdown of cone reconstruction, versus those with intact repair

From: A simple measure of the extent of Ebstein valve rotation with cardiovascular magnetic resonance gives a practical guide to feasibility of surgical cone reconstruction

Parameter Surgical dehiscence (n = 4) Intact cone reconstruction (n = 16)  
Ebstein valve rotation angle (EVRA) (degrees) 72 (60–78) 50 (20–71) *p = 0.01
Functional RV end-diastolic volume index (mL/m2) 132 (83–168) 177 (101–353) *p = 0.04
Age at surgery (years) 38 (33–57) 19 (14–45) *p = 0.01
