Overview
Recommendation for Evaluation and Follow-Up After Right Ventricular-Pulmonary Artery Conduit or Prosthetic Valve[1]
Class I |
"1. After surgical relief of RVOT obstruction with a conduit or prosthetic valve, patients should be followed up on a 1- to 2-year basis with echocardiographyDoppler assessment of RV systolic pressure and function, as well as a measurement of the gradient across the RVOT. (Level of Evidence: C) " |
Recommendations for Reintervention in Patients With Right Ventricular–Pulmonary Artery Conduit or Bioprosthetic Pulmonary Valve Stenosis
Class I |
"1. Surgeons with training and expertise in CHD should perform operations for patients with severe pulmonary
prosthetic valve stenosis (peak gradient greater than 50 mm Hg) or conduit regurgitation and any of the following:" a. Decreased exercise capacity.(Level of Evidence: C) b. Depressed RV function. (Level of Evidence: C) c. At least moderately enlarged RV end-diastolic size.(Level of Evidence: C) d. At least moderate TR. (Level of Evidence: C) |
Class IIa |
"1. Either surgical or percutaneous therapy can be useful in symptomatic patients with discrete RV pulmonary artery conduit obstructive lesions with greater than 50% diameter narrowing or when a bioprosthetic pulmonary valve has a peak gradient by Doppler
greater than 50 mm Hg or a mean gradient greater than 30 mm Hg. (Level of Evidence: C)" |
"2. Either surgical or percutaneous therapy can be useful in asymptomatic patients when a pulmonary bioprosthetic valve has a peak Doppler gradient greater than 50 mm Hg. (Level of Evidence: C)" |
