Systematic review identifies patterns in hearts with double-inlet double-outlet right ventricle, suggesting classification based on aortic atresia and venous connections.
Hearts with a double-inlet and double-outlet right ventricle are infrequent. Due to their infrequency, it is unclear whether there are natural patterns in hearts like this. A systematic review was performed to identify published cases of double-inlet double-outlet right ventricle. Characteristics for individual reported hearts were collated and entered into a cluster analysis. Hearts with double-inlet, double-outlet right ventricles tended to fall into two clusters largely based on aortic atresia and systemic venous connections.
