Sizing of mitral annuloplasty rings using real-time three-dimensional transesophageal echocardiography and the difference between patients with and without recurrent mitral regurgitation: retrospective cohort study.

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
backgroundPrevious studies showed that the mitral inter-commissural (IC) distance differed by a few millimeters between the systolic and diastolic cardiac cycles. However, sizing of the mitral annuloplasty ring with a ring sizer, which should be performed in the systole, is performed in diastole during hyperkalemic cardioplegic arrest. The aim of this study was to investigate whether three-dimensional transesophageal echocardiography (3D-TEE) measurements of the mitral valve in end-systole are effective to determine the size of the annuloplasty ring.
methodsThis study retrospectively reviewed 92 patients who underwent mitral annuloplasty for degenerative. The IC distance and anterior leaflet height of the A2 segment of the mitral valve were measured by 3D-TEE at the end-systole. The annuloplasty ring size was measured by the surgeons using specific ring sizers. We compared the IC distance measured by 3D-TEE with the implanted annuloplasty size. We also investigated differences in IC distance, A2 height, and ratio of A2 height to IC distance in patients with and without recurrent mild to moderate MR for 36 months.
resultsThere was a significant correlation between the IC distance by 3D-TEE and the implanted ring size (R
conclusionsOur results demonstrated a larger ratio of A2 height to IC distance in patients with recurrent MR. 3D-TEE could be useful for the ring sizing.
