PRIMARY outcome

Timeframe: Most Recent follow-up (average of 3-6 years post implant)

Population: The number of participants was limited to those participants with a hemodynamic measurement provided. Therefore, the total number in each group is less than the total participants in each group.

PRIMARY outcome

Timeframe: Since Implant of the Valve to a Maximum of 13.0 years

Evaluation of the following adverse events * Mortality (all cause and valve-related) * Reoperation/reintervention * Explant * Endocarditis * Structural valve deterioration (defined as \>40 mmHg peak pulmonary gradient or \>30 mmHg mean pulmonary gradient or moderately severe to severe pulmonary insufficiency) * Thrombosis * Thromboembolism (pulmonary embolism) * Non-structural dysfunction * Perivalvular leak * Bleeding * Hemolysis * Calcification
