Continuous Assessment of Left Ventricular Outflow Obstruction in Transcatheter Aortic Valve Implantation.
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
backgroundLeft ventricular outflow tract (LVOT) obstruction is a rare but fatal complication after transcatheter aortic valve implantation (TAVI). Early detection and timely intervention are essential for favorable clinical outcomes. CASE SUMMARY: We report a case of LVOT obstruction diagnosed and dynamically monitored via a SavvyWire (Haemonetics). A 78-year-old woman underwent transfemoral TAVI for severe valve stenosis, and continuous hemodynamic monitoring by the SavvyWire identified a significant aorto-left ventricular pressure gradient with systemic hypotension immediately after valve deployment, indicating LVOT obstruction. Prompt administration of intravenous fluids and vasopressors resulted in rapid hemodynamic stabilization. DISCUSSION: This case underscores the utility of the SavvyWire for immediate detection and management of dynamic LVOT obstruction, potentially improving safety profiles in TAVI procedures. TAKE-HOME MESSAGE: Continuous monitoring of the aorto-left ventricular pressure gradient can facilitate early diagnosis of LVOT obstruction in TAVI procedures.
