Combined impact of residual mitral regurgitation and iatrogenic mitral stenosis on outcomes after mitral transcatheter edge-to-edge repair with the mitraclip device

Key Points

• To evaluate how residual mitral regurgitation and iatrogenic mitral stenosis affect patient outcomes post-mitraclip repair.
• Patients who underwent mitraclip procedure were assessed for mitral regurgitation and stenosis.
• Outcomes post-procedure were measured and compared among groups with varying levels of mitral regurgitation and stenosis.
• Data analysis included statistical comparisons of clinical outcomes related to different severity levels.
• Patients with residual mitral regurgitation had poorer outcomes than those without.
• Iatrogenic mitral stenosis also led to worse clinical results post-mitraclip procedure.
• The combination of both conditions significantly increased the risk of adverse outcomes.
