Key result
Tailored hemodynamic optimization resolves dynamic MR and LVOT obstruction after SAVR, avoiding unnecessary intervention.
Why the study?
Mitral regurgitation often coexists with severe aortic stenosis and may persist or worsen after SAVR due to dynamic LVOT obstruction and systolic anterior motion.
Case Report (n=1)
Post-SAVR dynamic mitral regurgitation and LVOT obstruction from systolic anterior motion can be successfully managed medically with echocardiography-guided hemodynamic optimization rather than immediate percutaneous intervention.

Preoperative ventricular and mitral assessment may reduce post-SAVR instability risk; leaves open whether routine screening alters outcomes.
Mitral regurgitation (MR) frequently coexists with severe aortic stenosis and may persist or worsen after surgical aortic valve replacement (SAVR) despite afterload reduction. Following SAVR, abrupt ventricular unloading can unmask hyperdynamic ventricular function, promote systolic anterior motion and left ventricular outflow tract (LVOT) obstruction, resulting in dynamic MR and hemodynamic instability. A thorough preoperative assessment of ventricular geometry and mitral valve anatomy is crucial to identify patients at increased risk of post-SAVR LVOT obstruction. We describe a case of severe dynamic MR and LVOT obstruction following SAVR, successfully managed through comprehensive echocardiographic evaluation and tailored hemodynamic optimization, ultimately avoiding unnecessary percutaneous mitral intervention.

Farella et al. (2026) conducted a case report in Severe dynamic mitral regurgitation and LVOT obstruction following SAVR (n=1). Comprehensive echocardiographic evaluation and tailored hemodynamic optimization was evaluated. Tailored hemodynamic optimization successfully managed severe dynamic mitral regurgitation and LVOT obstruction following SAVR, avoiding unnecessary percutaneous mitral intervention.
