Diagnostic Value of Stress Right Heart Catheterization for Dynamic Mitral Regurgitation in Atrial Fibrillation.

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
backgroundAccurate evaluation of dynamic mitral regurgitation (MR) during stress echocardiography is challenging due to atrial fibrillation (AF), time constraints, and poor reproducibility. CASE PRESENTATION: An 85-year-old man with exertional dyspnea had moderate atrial functional MR on transthoracic echocardiography. Quantitative assessment during handgrip stress echocardiography was difficult due to AF. Stress right heart catheterization (RHC) with handgrip revealed increased mean pulmonary capillary wedge pressure and V-wave. The mitral transcatheter edge-to-edge repair markedly reduced MR. Postprocedural stress RHC demonstrated only slight increase in the mean pulmonary capillary wedge pressure and the V-wave. He remained free from heart failure hospitalization. DISCUSSION: AF increases the risk of atrial functional MR, making it common in clinical practice. Stress RHC with handgrip is a simple and reproducible invasive test even with AF. TAKE-HOME MASSAGE: Stress RHC with handgrip provides valuable diagnostic information when noninvasive results are inconclusive, especially in dynamic MR with AF.
