Intravascular Lithotripsy-Enabled Transcatheter Aortic Valve Replacement in Heavily Calcified Bicuspid Aortic Valve.
Article in JACC. Case reports, 2025. 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
backgroundTranscatheter aortic valve replacement (TAVR) in bicuspid aortic valves (BAVs), especially with severe calcification, presents challenges including prosthesis underexpansion and paravalvular leak. CASE SUMMARY: We present a critically unwell 70-year-old man with severe aortic stenosis in a heavily calcified Sievers-0 BAV, complicated by heart failure and chronic kidney disease. Intravascular lithotripsy (IVL) was used for calcium modification, followed by balloon valvuloplasty and deployment of a 26-mm Evolut PRO+ valve. The patient had excellent clinical recovery, with no paravalvular leak and improved ventricular function. DISCUSSION: This case highlights the novel use of IVL to facilitate TAVR in a complex calcified BAV anatomy. IVL enables controlled calcium fracture and improves compliance, optimizing prosthesis expansion and reducing complications. However, the lack of dedicated valvular IVL platforms remains a current limitation. TAKE-HOME MESSAGES: IVL may enhance lesion preparation in heavily calcified BAVs undergoing TAVR. Dedicated IVL devices for structural interventions are an emerging need.
