No complications were encountered during or immedi- ately after the procedures. Total contrast was 21 mL (2.8 mL/kg), total fluoroscopy time was 62.6 minutes, and dose area product (DAP) was 6.97 Gy·cm2.
Thrombosis of prosthetic valves leads to leaflet immobility and valve dysfunction and requires urgent management. Percutaneous manipulation of prosthetic valves is feasible and can be used as an alternative to surgery in selected patients who do not respond to or have contraindications to thrombolytic therapy. Further studies are necessary to demonstrate the safety and risks of this treatment across different patient subgroups and different types of pros- thetic valves.

Background/Introduction: Accurate Pulmonary Vascular Resistance (PVR) measurements are critical for clinical decision making in single ventricle (SV) congenital heart disease (CHD) patients. In this study, we describe the test-retest reliability of CMR and cardiac catheter (Fick principle) derived measurements of pulmonary (Qp) and systemic (Qs) blood flows. Real-time CMR imaging was used to guide catheters/wires and all measurements were obtained without the use of ionizing radiation.
