Table 67. Step 4: Evaluation of prosthetic valve thrombosis prognostic factors.

Prognostic factors
High risk of embolization associated with thrombolysis

  • Thrombus > 8 mm

  • Mobile thrombus (pedunculated)
Pulmonary hypertension

  • Resting SPAP ≥ 50 mmHg

  • More frequent when there is associated MS

  • Clinically – symptoms of right heart failure

  • Related to increased surgical risk
Recent onset AF

  • Related to significant LA remodeling

AF: atrial fibrillation; LA: left atrium; MS: mitral stenosis; SPAP: systolic pulmonary artery pressure.
