Concomitant Dynamic Left Ventricular Outflow Tract Obstruction and Severe Aortic Stenosis a Case Report and a Literature Review.
Article in Journal of cardiovascular echography. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
We report the case of a 77-year-old woman presenting with a hypertrophic cardiomyopathy phenotype characterized by hemodynamically significant dynamic left ventricular outflow tract obstruction (LVOTO) due to mitral systolic anterior motion (SAM), in association with aortic stenosis (AS). The clinical presentation included an episode of syncope, followed by progressive exertional dyspnea. Initial transthoracic echocardiography revealed marked septal hypertrophy, a calcified aortic valve with elevated transvalvular gradients, and SAM-induced dynamic LVOTO. Sarcomeric hypertrophic cardiomyopathy (HCM) and its phenocopies were subsequently excluded from the study. Transesophageal echocardiography confirmed the coexistence of severe AS and SAM. Given the complexity of the patient's cardiac condition and the presence of a "porcelain aorta," both surgical and transcatheter aortic valve replacement were deemed high risk. We discuss the diagnostic and therapeutic challenges of this "double-threat" scenario - severe aortic stenosis combined with dynamic LVOTO - and review the relevant literature regarding its hemodynamic implications, imaging strategies, and management approaches, including the concept of the "suicide left ventricle".
