Percutaneous closure of paravalvular leak (PVL) is a safe alternative to surgery, with 86% clinical success. This minimally invasive approach is particularly effective for patients with heart failure (HF).
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Significant paravalvular leak (PVL) affects 1-3% of patients post-valve replacement.
- Surgical PVL repair has a high 30-day mortality rate of approximately 10%.
- Percutaneous PVL closure is an emerging alternative to surgical intervention.
Purpose of the Study:
- To evaluate the clinical outcomes of percutaneous PVL closure.
- To assess the safety and efficacy of this minimally invasive technique.
- To identify patient subgroups who benefit most from percutaneous PVL closure.
Main Methods:
- Prospective registry for patient and procedural data.
- Retrospective review of medical records for outcomes.
- Analysis of clinical success, complications, and mortality.
Main Results:
- 26 procedures in 21 patients (mean age 68 years).
- 86% overall clinical success, higher in heart failure (HF) patients (100%) vs. hemolysis (HL) (66%).
- 0% 30-day mortality, one stroke (3.8%), 28% mortality at 22-month follow-up.
Conclusions:
- Percutaneous PVL closure is a safe and effective alternative to surgery.
- It is particularly beneficial for patients presenting with heart failure.
- PVL patients represent a high-risk group, benefiting from less invasive options.
