Cardio-Obstetric Mortality Risk (CO-RISK) Calculator

  • Prior Cardiac Events or Arrhythmias
  • NYHA Functional Class III-IV or Cyanosis
  • Mechanical Valve
  • Systemic Ventricular Dysfunction (LVEF <55%)
  • High-Risk Valve Disease or Left Ventricular Outflow Tract Obstruction
  • Pulmonary Hypertension (RVSP >49 mmHg)
  • High-Risk Aortopathy
  • Coronary Artery Disease
  • No Prior Cardiac Intervention
  • Cardio-Obstetric Mortality Risk (CO-RISK) Model: Explanation and Clinical Context
     The CO-RISK model, derived from the CARPREG II score, assesses the risk of primary cardiac events in pregnant women with heart disease. This model assigns points based on the presence of specific cardiac risk factors, including prior cardiac events, NYHA functional class, mechanical valve, left ventricular dysfunction, high-risk valve disease, pulmonary hypertension, aortopathy, coronary artery disease, and absence of prior cardiac intervention. The total score stratifies patients into risk categories, aiding clinicians in identifying high-risk pregnancies and guiding management strategies to improve maternal and fetal outcomes.
