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
objectivesThis study examined the indications, frequency, and outcomes of cardiac surgery following transcatheter aortic valve replacement (TAVR) at a single institution. As TAVR volumes increase, understanding the nature and outcomes of subsequent cardiac operations is critical, particularly as the procedure expands to younger, lower-risk populations.
methodsWe analysed outcomes of 61 patients who underwent cardiac surgery after TAVR at our institution from August 2011 to September 2023, excluding periprocedural complications and staged procedures. Patients were stratified into 2 groups: those requiring surgical aortic valve replacement (SAVR) with or without concomitant procedures (n = 33) and those undergoing non-SAVR cardiac operations (n = 28). Data were collected from a prospectively maintained cardiovascular surgery database and electronic health records. Indications for surgery, operative characteristics, and outcomes were analysed, with survival assessed using Kaplan-Meier estimates.
resultsThe median interval between TAVR and cardiac surgery was 19 months. Indications for SAVR included infective endocarditis (36%), non-structural valve deterioration (36%), structural valve deterioration (12%), and valve thrombosis (6%). Non-SAVR operations primarily addressed mitral valve disease (43%) and coronary artery disease (29%). Operative mortality was 6.6%, with no deaths in the endocarditis subgroup. Postoperative complications included prolonged mechanical ventilation (18%), new-onset renal failure (7%), and stroke (2%). Kaplan-Meier survival estimates were 83% at 1 year and 50% at 5 years.
conclusionsAlthough complex, cardiac operations in patients who have undergone TAVR can be performed with acceptable mortality rates. Structural valve deterioration, paravalvular leak, and endocarditis were the primary indications for SAVR, while mitral valve and coronary artery disease predominated in non-SAVR cases. These findings highlight the importance of considering nonaortic valve pathologies in TAVR planning, particularly as the procedure expands to younger, lower-risk populations.
