🫀 New Ideas in Cardiology — March 2026 (ACC Conference Coverage Highlights)
📌 Source: TCTMD (ACC 2026 coverage)
1-Mitral Hemivalve (Polaris)
👉 Replace only the posterior leaflet
→ Preserve the native anterior leaflet
→ Less complex than full valve replacement
→ Designed to reduce LVOT obstruction and improve physiology
2-Echo = The Eyes of The Structural Procedure
👉 Essential for guiding modern structural interventions
→ Provides real-time visualization inside the heart
👉 Interventional Echo specialists exposed to higher radiation (~×12)
👉 New ceiling-suspended suit (Zero-Gravity)
→ Achieves near-zero radiation exposure
3-LAVA-ECMO
👉 Drains blood directly from the left atrium (transseptal)
→ Reduces afterload in severe mitral regurgitation
→ Provides biventricular unloading
👉 Serves as a bridge to definitive valve therapy
4-Leaflet Lengthening (CARLEN)
👉 Instead of clipping → extend the leaflet
→ Works on anterior or posterior leaflet
→ Expands treatment options beyond anatomical limits
📊 Additional Insights
• Tricuspid regurgitation affects mitral outcomes
• Ongoing debate: intervention in moderate MR
Bottom Line
👉 Cardiology is moving toward:
Simpler, more physiological, and safer structural solutions
