A retrospective analysis of hemodynamic stability in TAVR and TTVR under general anesthesia: implications for sedation in TTVR.

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) is routinely performed under general anesthesia (GA) or sedation. However, there were few studies focused on the anesthesia method when transcatheter tricuspid valve replacement (TTVR) was performed. This study aimed to investigate whether TTVR procedures can be performed effectively under sedation.
methodsWe conducted a retrospective analysis of 45 patients who underwent TAVR and 56 patients who underwent TTVR at Shanghai General Hospital between August 2023 and November 2024. The primary endpoints were the incidence of hemodynamic fluctuations and the administration of vasoactive drugs during the surgical procedures. The secondary outcomes included perioperative complications. All relevant clinical data were meticulously collected and analyzed using standardized protocols.
resultsThe groups did not differ in characteristics, comorbidities and cardiac function, or myocardial injury indicators. More patients in the TAVR group experienced post-induction hypotension. The duration of hypotension was significantly longer in the TAVR group. The magnitude of MAP decline and the heart rate were more considerable in the TAVR group than in the TTVR group during the operation. The dosage of vasopressor agents was higher in the TAVR group than in the TTVR group. Finally, the clinical outcomes of patients from both groups did not differ between the two groups after surgery.
conclusionsPerforming TTVR have fewer harmful effects on hemodynamic stability and a lower likelihood of sudden incidents under GA. The results suggested that sedation may be a suitable and safe anesthesia method for TTVR and is worthy of future investigation.
