Echocardiographic characteristics of coronary sinus in patients with arrhythmia and in healthy controls: a single-center clinical 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
Background: The coronary sinus (CS) is an anatomical structure that is often targeted in cardiac intervention. Different CS forms may be related to the occurrence of various arrhythmias. This study primarily analyzed whether there are differences in the CS between healthy participants and patients with common arrhythmia. Methods: In this cross-sectional study, the relevant information of patients diagnosed with arrhythmia via electrocardiography and that of healthy controls in whom arrhythmia was excluded via electrocardiography in Shandong Provincial Hospital from June 2024 to May 2025 was collected. The CS diameters were measured by tilting the standard apical four-chamber view toward the foot side to display the maximum cross-sectional area of the CS long axis. CS hemodynamic information was acquired at the right ventricular inflow tract view. Results: The CS ostium diameter of healthy controls was 0.76±0.17 cm, and the normal range was 0.43-1.09 cm. The diameter of the CS ostium in patients with paroxysmal atrial fibrillation (PAF), persistent atrial fibrillation (Pers AF), supraventricular tachycardia (SVT), and frequent premature ventricular contractions (FPVCs) were 0.82±0.17, 1.03±0.22, 0.92±0.34, and 0.83±0.22 cm, respectively. One-way analysis of variance (ANOVA) comparisons revealed statistically significant differences between healthy controls and patients with Pers AF, SVT, and FPVC (P<0.001, P=0.029, and P=0.039, respectively). After matching was performed for sex, age, body surface area (BSA), and right atrial area (RAA), the difference in CS ostium diameter between patients with Pres AF and healthy controls was not statistically significant. However, the morphological difference between healthy controls and patients with SVT and Pers AF was statistically significant (P=0.004 and P=0.015, respectively). Conclusions: The diameters of the CS ostium in patients with Pers AF, SVT, and FPVC were increased, which may play a role in the occurrence, maintenance, and recurrence of arrhythmia. Moreover, in patients with SVT and Pers AF, the proportion of wedge-shaped CS was higher than that in healthy controls.
