Does the cone operation improve left ventricular size, function, and dyssynchrony in patients with Ebstein anomaly?
The cone operation mitigates the detrimental effect of the right ventricle on left ventricular function in patients with Ebstein anomaly.
In patients with the Ebstein anomaly, the cone operation led to reduced TR and RV stroke volume, increased LV stroke volume, improved LV basal septal strain, and improved LV synchrony. Our data demonstrates that the detrimental effect of the RV on LV function can be mitigated by the cone operation.
