Prospective Study, Single Arm to evaluate the safety and efficacy of polyurethane expandable valve implantation in the pulmonary position, in 5 patients over 18 years of age, with pulmonary valve dysfunction and moderate to severe impairment of Right Ventricular function. During throughout the study, safety parameters related to valve operation will be evaluated (patient's Functional Class), in addition to the occurrence of Serious Adverse Events. After the procedure, the patient must be hospitalized in the Intensive Care Unit until the complete hemodynamic stabilization and normalization of lung function and in good general condition (2 to 3 days of stay) and then transferred to the ward (2 to 3 days and stay) before hospital discharge. A formal Statistical Analysis Plan (SAP) will be developed and finalized before closing the database. Full details of data presentations and analysis will be provided in SAP.
Additional statistical analyses, other than those described in this section, may be performed if deemed appropriate and included in SAP. Any deviations from the final analysis plan or what is presented in the protocol will be discussed in the final study report. No formal inferential statistics will be applied to the data collected in the study.

|---|---|---|---|---|
| Polyurethane expandable valve stent implant | Device | The baseline assessment of patients will include the admission of patients and the performance of preoperative exams (cardiological imaging for the correct selection). An estimated surgery time of 5 hours. During the entire procedure, patients will be under general anesthesia and controlled mechanical ventilation. The material collected in the laboratory will be processed, the result released and discarded. After the patient enters the operating room, hemodynamic monitoring, ECG, arterial saturation, with peripheral sensor, central venous access with double lumen catheter will be carried out; blood pressure monitoring by radial artery puncture, bladder catheter and thermometer in the nasopharynx and rectum. After preoperative preparation, patients will undergo a surgical approach by median thoracotomy and installation of the Cardiopulmonary bypass (ECC) circuit, by placing a cannula in the ascending aorta, Superior Vena Cava (SVC) and Inferior Vena Cava (IVC). |
