A prospective 5-year study of exercise performance following melody valve implant

ConclusionsA cautious appraisal of the cardiovascular benefits of Melody valve implant on sustained improvements in exercise performance appears warranted. While the observed changes in pulmonary function suggest improved restrictive lung physiology and more efficient gas exchange, after an initial increase in %predicted performance, neither sustained nor further improvements in exercise performance were observed, except in specific patient subgroups.
