Risky Mitral Valve Calculator

  • Leaflet thickening (1 if yes, 0 if no)
  • Leaflet calcification (1 if yes, 0 if no)
  • Restricted leaflet motion (1 if yes, 0 if no)
  • Annulus dilation >40 mm (1 if yes, 0 if no)
  • Subvalvular apparatus abnormality (1 if yes, 0 if no)
  • Mitral valve area <1.5 cm² (1 if yes, 0 if no)
  • Mean gradient >10 mmHg (1 if yes, 0 if no)
  • Pulmonary hypertension (1 if yes, 0 if no)
  • Left atrial thrombus (1 if yes, 0 if no)
  • Risky Mitral Valve (Echo-based risk stratification): Explanation and Clinical Context
    The Risky Mitral Valve concept uses echocardiographic assessment to identify mitral valve disease patients at high risk of complications during or after intervention.
    Key echocardiographic parameters include leaflet morphology (thickening, calcification, restricted motion), annular dilation, subvalvular apparatus abnormalities, mitral valve area, pressure gradient, pulmonary hypertension, and presence of left atrial thrombus.
    By quantifying these factors into a risk score, clinicians can stratify patients into low, moderate, or high-risk categories, guide surgical or transcatheter intervention decisions, optimize perioperative management, and counsel patients about potential outcomes.
