Key result

Discrete subaortic stenosis pathogenesis is increasingly attributed to a hemodynamic etiology where left ventricular outflow tract geometric derangements generate abnormal shear forces that trigger a fibrotic response.

Implication

Does not support practice changes in discrete subaortic stenosis; leaves open mechanistic pathways for future research.

This perspective paper outlines a research roadmap to investigate the hemodynamic and mechanobiological etiology of discrete subaortic stenosis to identify early targets for prevention.

Limitations

  • Current in vivo canine models have limitations in understanding how DSS forms and the underlying mechanism.
  • Validating the hemodynamic etiology and understanding the mechanobiological processes by which altered shear forces induce fibrosis remain major knowledge gaps.
