Right Heart Pressure Contraindications for TIPS

A right atrial pressure (RAP) >14 mmHg at the time of planned TIPS insertion is a contraindication that requires right heart catheterization to exclude portopulmonary hypertension before proceeding with TIPS. 1

Cardiopulmonary Assessment Before TIPS

Right-Sided Heart Pressure Thresholds:

  • Right atrial pressure (RAP) >14 mmHg: Requires right heart catheterization before proceeding 1
  • Right ventricular systolic pressure (RVSP) >45 mmHg: Requires cardiology referral for right heart catheterization 1, 2
  • Post-TIPS RAP >22 mmHg: Associated with significantly increased risk of heart failure and mortality 3

Other Cardiac Contraindications:

  • Mean pulmonary artery pressure (mPAP) >35 mmHg: Moderate to severe portopulmonary hypertension requires extreme caution 1
  • Pulmonary vascular resistance (PVR) >3 Wood units: Indicates significant portopulmonary hypertension 1
  • Left ventricular ejection fraction (LVEF) <50%: TIPS should be avoided 1
  • Grade III diastolic dysfunction: TIPS should be avoided 1

Pre-TIPS Evaluation Algorithm

  1. Echocardiographic screening:

    • Assess RVSP (threshold >45 mmHg)
    • Measure tricuspid annular plane systolic excursion (TAPSE) (threshold <1.6 cm)
    • Evaluate left ventricular function (LVEF threshold <50%)
    • Assess for diastolic dysfunction (avoid if grade III)
    • Evaluate for tricuspid regurgitation

  2. During TIPS procedure:

    • Measure RAP before shunt creation (threshold >14 mmHg)
    • If elevated, consider right heart catheterization
    • After TIPS placement, monitor post-TIPS RAP (risk increases significantly at >22 mmHg)

Clinical Implications and Pitfalls

  • TIPS physiological effects: TIPS acutely increases RAP by 3-5 mmHg even in patients without pulmonary hypertension 4
  • Mortality risk: Elevated pre-TIPS RAP is independently associated with overall mortality after TIPS insertion 5
  • Early complications: Higher pre-TIPS RAP increases odds of early complications and portal hypertensive complications 5
  • Post-TIPS surveillance: Patients with borderline right heart pressures who undergo TIPS should have echocardiographic surveillance at 3 months 1

Special Considerations

  • In patients with moderate or severe portopulmonary hypertension, TIPS may precipitate right-sided heart failure 1
  • Patients with moderate to severe tricuspid regurgitation despite optimization of volume overload should undergo evaluation for underlying cardiopulmonary etiology before TIPS 1
  • Consider using smaller diameter TIPS (8mm) in patients with borderline cardiac function to minimize cardiac stress 1

The risk of post-TIPS heart failure ranges from 1% at one week to 20% at one year, with elevated right heart pressures being a significant predictor of adverse outcomes 6, 3. Careful pre-procedure assessment of right heart pressures is essential to prevent post-TIPS cardiac decompensation and mortality.
