Key result
Patient-specific pulmonary valved stent construction achieves ~92% success among procedural trainees.
Why the study?
Valved stents are a novel technology for cardiac surgeons with increasing use by interventionalists, requiring practical steps for patient-specific construction and delivery.

Simple assembly of patient-specific pulmonary valved stents appears feasible; leaves open translation to clinical use.
Valved stents are new land for cardiac surgeons even though they are being used more frequently by interventional disciplines. This paper presents simple steps to build a patient-specific pulmonary valved stent and its delivery device. The design concept was tested by random participants at a med-tech meeting. The valved stent is constructed by linking an endoprosthetic graft with a valved-jugular-vein. The delivery device is made from a modified 5-ml syringe. Of 72 participants, 66 (92%) built and 60 participants implanted the device successfully into the targeted pulmonary position via a trans-infundibular access.
