Key result
Serial aortic valvuloplasties and endocardial fibroelastosis resections enabled successful biventricular conversion in hypoplastic left heart syndrome.
Demonstrates the feasibility of a staged left ventricular recruitment pathway for biventricular conversion in hypoplastic left heart syndrome.
May support staged LV recruitment in select HLHS cases; hypothesis-generating and requires prospective validation before practice change.
We describe a relatively long left ventricular recruitment pathway consisting of early and serial aortic valvuloplasties and multiple endocardial fibroelastosis resections resulting in successful biventricular conversion of hypoplastic left heart syndrome.
