Clinical and echocardiographic outcomes of patients with mitral annular calcification undergoing mitral valve surgery: a 10-year single center experience.

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
Background: Mitral annular calcification (MAC) is a chronic and degenerative process, affecting the mitral valve annulus. MAC complicates the decision over the appropriate surgical approach to mitral valve disease. Distorted valvular anatomy increases surgical risk and therefore requires careful patient selection. Here, we report our single-center experience performing mitral valve surgery in the setting of MAC over a 10-year period. Methods: This is a 10-year retrospective analysis of 172 patients with MAC. Sixty-seven patients underwent MAC severity scoring using a 10-point system based on computed tomography (CT). The primary outcome was 30-day mortality, readmission, reoperation, stroke, prolonged ventilation, renal failure and deep sternal infection. Secondary analyses stratified MAC by underlying mitral disease type as well as evaluated outcomes by CT severity score. Patients without MAC undergoing mitral valve replacement surgery during the same time period served as controls. Results: The 30-day mortality was significantly higher in MAC patients compared with non-MAC (9.9% Conclusions: MAC complicates mitral valve surgery, with significant differences seen in survival stroke, renal failure, prolonged ventilatory support, and ICU and hospital length of stay. Careful evaluation of surgical risk and patient selection is warranted in patients with MAC.
