Key result
Percutaneous paravalvular leak closure achieved an 89.7% technical success rate and an 82.1% clinical success rate over a mean follow-up of 33.5 months.
Why the study?
Paravalvular leak is a common complication after valve replacement leading to heart failure and hemolysis, and transcatheter closure has emerged as a promising alternative.
Does transcatheter closure of paravalvular leak improve functional status and hemolysis in patients with PVL?
Observational (n=39)
Yes
Does transcatheter closure of paravalvular leak improve functional status and hemolysis in patients with PVL?
Transcatheter closure of paravalvular leak is a safe and effective alternative to surgery, yielding high technical and clinical success rates with significant functional improvement.
No takes yet. Share an insight, caveat, or question.
May support transcatheter PVL closure in selected patients; hypothesis-generating and requires randomized trials before practice change.
Kalogeras et al. (2021) conducted an observational in Paravalvular leak (PVL) (n=39). Percutaneous paravalvular leak closure was evaluated on Technical success (successful deployment). Percutaneous paravalvular leak closure achieved an 89.7% technical success rate and an 82.1% clinical success rate over a mean follow-up of 33.5 months.
