Peripheral intravascular lithotripsy in transcatheter aortic valve implantation: a case report.

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
Background: The presence of severe calcific atherosclerosis at the iliofemoral axis may preclude transcatheter aortic valve replacement (TAVR) by the transfemoral (TF) approach. Intravascular lithotripsy (IVL) is a novel technology that fractures intimal/medial calcium, increasing vessel compliance and enabling TF-TAVR in selected patients with peripheral artery disease. Case summary: A 76-year-old female presented with severe degenerative calcific aortic valvular stenosis. The patient was planned for TAVR due to high surgical risk status. However, computed tomography analysis revealed significant aortoiliac calcific narrowing, which limited TF access. Intravascular lithotripsy was performed to modify the calcific stenosis in the aortoiliac region, after which TAVR was successfully completed via the transfemoral route. This intervention was crucial in allowing TAVR to be performed at a low risk. The procedure was successful, and the patient was doing well at 8-month follow-up. Discussion: Peripheral IVL appears to be a safe and effective solution for TAVR candidates with co-existing iliofemoral calcifications. Using peripheral IVL to facilitate TF access should be part of the TAVR algorithm, to maintain the safety profile and superior outcomes of traditional TF-TAVR. More research is needed to improve the understanding of anatomical selection for IVL in TAVR candidates. Operators performing IVL-assisted TF-TAVR should be familiar with endovascular interventions and bailout solutions, not so much to treat IVL-treated lesions, but to be able to treat any vascular complication that may occur at the puncture site.
