Key result
A Ross-Konno procedure with concomitant EFE resection and mitral valve repair completely relieved multi-level obstruction and mitral regurgitation with markedly improved LV function.
Why the study?
Determining the feasibility of biventricular repair in infants with critical AS is challenging, particularly with mitral disease, EFE, multi-level obstruction, and uncertain physiologic capacity.
Case Report (n=1)
A Ross-Konno procedure with concomitant EFE resection and mitral valve repair is feasible and can successfully relieve multi-level obstruction and improve LV function in infants with critical AS and complex left heart disease.
May support Ross-Konno in select infants with critical AS and complex LV issues; hypothesis-generating and should not yet change practice.
Optimal management of critical aortic stenosis (AS) in infants depends on the left ventricle's (LV's) ability to maintain adequate output. Determining feasibility of biventricular repair may be difficult, particularly in those with mitral disease, endocardial fibroelastosis (EFE), multi-level obstruction, and uncertain physiologic capacity. We report a case of a three-month-old with critical AS, severely reduced LV function, EFE, and moderate mitral regurgitation (MR), who underwent a Ross-Konno procedure with concomitant EFE resection and mitral valve repair. Although the technical sequence is challenging, definitive surgery completely relieved multi-level obstruction and MR with markedly improved LV function.

Najm et al. (2021) conducted a case report in Critical aortic stenosis (n=1). Ross-Konno procedure with concomitant EFE resection and mitral valve repair was evaluated on Relief of multi-level obstruction and mitral regurgitation with improved LV function. A Ross-Konno procedure with concomitant EFE resection and mitral valve repair completely relieved multi-level obstruction and mitral regurgitation with markedly improved LV function.
