First-in-Human Use of Intravascular Lithotripsy to Facilitate Mitral Balloon Commissurotomy After Prior Annuloplasty Band Repair.
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
backgroundPatients with severe mitral stenosis (MS) after surgical repair often face limited therapeutic options owing to high surgical risk and complex valve anatomy. CASE SUMMARY: A 79-year-old woman with prior surgical mitral valve repair presented with severe MS. Given her high surgical risk and extensive valvular calcification, she was not a candidate for redo surgical mitral valve, percutaneous mitral balloon commissurotomy (PMBC), or transcatheter mitral valve-in-ring. Intravascular lithotripsy (IVL)-facilitated PMBC was performed, with postprocedural improvement in gradients and symptoms. DISCUSSION: IVL was used to modify calcific leaflets, enabling successful commissurotomy in complex postsurgical anatomy. Comparative hemodynamic data are needed to clarify IVL's contribution. TAKE-HOME MESSAGES: IVL can be used off-label for severe MS with prior incomplete annuloplasty band where surgery, transcatheter mitral valve-in-ring, and PMBC are not viable options. IVL-facilitated PMBC still remains investigational; larger studies and longer term follow-ups are required to define safety, durability, and patient outcomes.
