Predictors of Mitral Regurgitation Severity Improvement in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation.

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
backgroundMitral regurgitation (MR) is frequently associated with severe aortic stenosis (AS). Significant MR is associated with less favorable prognosis after transcatheter aortic valve implantation (TAVI), including higher early and late mortality rate. The severity of MR is improved in about half of patients undergoing TAVI. However, the predictors of MR improvement after TAVI are unknown. We sought to investigate whether several demographic, clinical, echocardiographic and laboratory parameters and procedure characteristics are predictive of MR severity improvement after TAVI procedure.
methodsA total of 309 consecutive patients with severe symptomatic AS underwent TAVI procedure in our center from July 1, 2015 till December 31, 2019. The 85 patients had concomitant significant (grade 2 or 3) MR. We performed logistic regression analysis of age, sex, atrial fibrillation, left ventricular ejection fraction, end diastolic diameter, end systolic diameter, left atrial diameter, left atrial area, MR etiology (functional vs. degenerative), CHA2DS2-VASc score, pre-procedure B-type natriuretic peptide (BNP) levels and type of TAVI bioprosthesis as possible predictors of post-TAVI improvement of severity of MR.
resultsThe 35 patients have at least one grade reduction in the severity of MR in follow-up echo. None of the analyzed parameters were predicting of the MR severity improvement.
conclusionsIn this small single-center cohort study, we were unable to find any feasible demographic, clinical, echocardiographic or laboratory predictors of MR improvement after TAVI. There was no correlation between etiology of MR or type of TAVI bioprosthesis used and MR improvement.
