Key result
Mitral valve reconstruction without an annuloplasty ring resulted in systolic anterior motion of the mitral valve with significant outflow tract obstruction requiring valve replacement.
Case Report (n=1)
Systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction can occur after mitral valve reconstruction even without the use of an annuloplasty ring.

SAM with LVOTO can complicate ringless mitral reconstruction; Level 5 evidence leaves open annuloplasty's protective role.
Niederhäuser et al. (1995) conducted a case report in Mitral regurgitation and ischemic heart disease (n=1). Mitral valve reconstruction without an annuloplasty ring was evaluated on Systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction. Mitral valve reconstruction without an annuloplasty ring resulted in systolic anterior motion of the mitral valve with significant outflow tract obstruction requiring valve replacement.
