Late Complications of TAVR: Endocarditis and Dissection Managed With Strategic Surgery.

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
backgroundProsthetic valve endocarditis (PVE) and aortic dissection are rare but severe complications of transcatheter aortic valve replacement (TAVR), with no standardized surgical approach. CASE SUMMARY: A 74-year-old woman developed PVE 6 months after TAVR with an Evolut PRO+ valve (Medtronic). Echocardiography revealed valve vegetation and perivalvular leakage, and computed tomography showed localized ascending aortic dissection. Emergency surgery involved careful removal of the Evolut PRO+ using sutureless aortic valve replacement and ascending aorta replacement. DISCUSSION: Successful management of TAVR-related PVE with aortic dissection in high-risk patients requires a clear understanding of prosthetic valve characteristics and tailored surgical planning. Techniques such as cold-water explantation and sutureless aortic valve replacement can be particularly useful in minimizing operative risk. TAKE-HOME MESSAGES: This case highlights a reproducible strategy for complex TAVR complications. Cold-water explantation and the snare technique allows safe valve removal, while sutureless aortic valve replacement shortens procedural time, offering practical advantages in high-risk patients.
