Abstract :

Objective: Ebsteinâ�?�?s anomaly remains a relatively ignored disease. Lying in the â�?�?No Manâ�?�?s landâ�?�? between congenital and valve surgeons it largely remains, under studied. We report our short-term results of treating it as a â�?�?one and a half ventricle heartâ�?�? and to propose that the true tricuspid annulus (TTA) Z-score be used as an objective criterion for estimation of functional right ventricle (RV). Method: 22 consecutive patients undergoing surgery for Ebsteinâ�?�?s anomaly were studied. Echocardiography was performed to assess the type and severity of the disease, tricuspid annular dimension and its Z-score patients were operated by a modification of the cone repair, with addition of annuloplasty, BCPC and right reduction atrioplasty to give a comprehensive repair. TTA Z-score was correlated later with post-plication indexed residual RV volume. Result: There was one (4.5%) early and no late post-operative mortality. There was a significant reduction in tricuspid regurgitation grade. (3.40�?±0.65 to 1.22�?±0.42, p<0.001). Residual RV volume reduced to 71.96�?±3.8% of the expected volume and there was a significant negative correlation (rho: -0.83) between TTA Z-score and indexed residual RV volume. During follow-up of 20.54�?±7.62 months, the functional class improved from 2.59+0.7 to 1.342�?±0.52 (p<0.001). Conclusion: In Ebsteinâ�?�?s anomaly, a higher TTA Z-score, correlates with lower post-plication indexed residual RV volume. Hence, a complete trileaflet repair with offloading of right ventricle by BCPC shunt (when TTA Z-score is >2) is recommended. The short-term outcomes of our technique are promising. drkartikpgi@yahoo.com
