Why the study?
Does delaying mitral valve surgery adversely affect outcomes in patients with grade ≥3 primary mitral regurgitation and preserved exercise capacity?
Does delaying mitral valve surgery adversely affect outcomes in patients with grade ≥3 primary mitral regurgitation and preserved exercise capacity?
In patients with significant primary mitral regurgitation, preserved exercise capacity on stress echocardiography identifies a subgroup where delaying mitral valve surgery by ≥1 year does not adversely affect long-term outcomes.
No takes yet. Share an insight, caveat, or question.
Supports delaying surgery ≥1 year in primary MR with preserved exercise capacity; leaves open need for randomized trials to guide timing.
