However, the management of chronic pulmonary regurgitation (PR) in native or patched RVOT remains challenging with the vast variation in morphology, leading to the demand for novel self\u2010expandable valves.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To report procedural performance and medium\u2010term follow\u2010up data of the Med Zenith PT\u2010Valve for tPVR in native or patched RVOT from a single\u2010center feasibility trial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifteen patients with PR were recruited for candidacy assessment, with 12 tPVR procedures performed with per\u2010protocol follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Amongst patients recruited, one with concomitant aortic pathology was diverted to surgery; there was one screen failure (7.1%) and one patient withdrew consent. Twelve patients underwent tPVR with the study valve with 100% success rate. Complications included one wire\u2010related pulmonary hemorrhage, one transient brachial neuropraxia, one femoral pseudoaneurysm, and two patients with non\u2010sustained ventricular tachycardia Day 1 post\u2010tPVR. Both patients received a short course of a beta\u2010blocker without recurrence of arrhythmia. There were no deaths or valve\u2010related reinterventions with a median follow\u2010up of 28.5 months (range 17.9\u201340.0 months). One episode of infective endocarditis was managed conservatively with antibiotics with no sequelae. There were otherwise no late complications. Significant improvement in biventricular volume and PR fraction was observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The Med Zenith PT\u2010Valve has performed well over short to mid\u2010term follow\u2010up in patients with significant PR in native or patched RVOT.
