Multiple Mitral Paravalvular Leak Closure With VSD Occluder in a High Surgical Risk Patient.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMitral paravalvular leak (PVL) is a common complication after surgical mitral valve replacement, often causing symptomatic congestive cardiac failure. When transcatheter closure is planned, transesophageal echocardiography is essential for guiding percutaneous device closure. CASE SUMMARY: A 21-year-old woman with rheumatic heart disease and prior metallic mitral valve replacement presented with congestive cardiac failure. Transesophageal echocardiography revealed mitral paravalvular leaks and low ejection fraction. Considering her high surgical risk, the heart team opted for percutaneous PVL closure. DISCUSSION: Mitral PVL after surgical mitral valve replacement can occur due to valve suture dehiscence. To our knowledge, we report the first case of multiple serpiginous mitral PVLs successfully closed in a single sitting, using 2 KONAR-MF VSD occluder devices, in a high surgical risk patient. The case highlights the flexibility and conformability of the KONAR-MF VSD occluder device, enhanced deliverability using a smaller sheath, and occlusive fabric promoting improved sealing. Tailored transcatheter closure can produce successful outcomes while minimizing the risk profile, in complex situations. TAKE-HOME MESSAGE: Transcatheter closure of mitral PVLs with the KONAR-MF VSD occluder device is a safe and effective alternative to redo surgery in high surgical risk patients, providing symptomatic relief and improved cardiac function.
