Transcatheter repair of paravalvular leak offers similar long-term survival and procedural success to surgery, with fewer periprocedural complications but a risk of hemolysis.
No takes yet. Share an insight, caveat, or question.
May support transcatheter repair to reduce early complications; leaves open need for randomized trials to confirm equivalence.
