Prognostic impact of right ventricular dysfunction in patients with severe aortic stenosis treated with trans-catheter aortic valve implantation: comment and validation from a small real-world cohort.

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
Right ventricular dysfunction is a known predictor of early mortality after TAVI. TAPSE is a practical echocardiographic index of RV function. To assess whether baseline TAPSE predicts 30-day mortality after TAVI in a real-world cohort. Among 21 patients, those with TAPSE < 17 mm had higher 30-day mortality (28.6% vs 7.1%). PASP was higher in the low-TAPSE group (45 ± 12 vs 32 ± 10 mmHg; p = 0.03). Non-survivors had a lower TAPSE/PASP ratio than survivors (median 0.351 [IQR 0.288-0.419] vs 0.607 [0.406-0.667]; exact p = 0.078), in line with a trend toward worse RV-pulmonary arterial coupling. A multivariable model including TAPSE, age, and EuroSCORE II showed apparent perfect discrimination (AUC = 1.00) within this very small dataset (3 events), likely overestimating true performance due to overfitting. TAPSE may serve as a simple, effective tool for early risk stratification in TAVI candidates as an adjunct to-rather than a replacement for-comprehensive geriatric/frailty assessment and established risk scores; estimates are unstable due to the small sample and event count.
