The aim of this study was to assess the influence of the parameters of the coronary sinus (CS) on the parameters that describe the function of the right ventricle (RV), which were calculated using cardiac computed tomography.
A CT scan of the heart was performed on 150 patients due to suspicion of coronary artery disease using a Siemens Somatom Force (2 × 192 × 0.6) and a syngo.via workstation. The "CT coronary" and in some cases the generic presets were used to measure the CS ostium in millimeters (mm). The functional measurements of right heart ventricles were examined using the "CT cardiac function" automatic function on a 256 × 256 matrix.
The average diameter of the CS ostium was 16.29 ± 4.37 mm. In the group with RV impairment, it was 16.56 ± 4.76, whereas in the group with normal values of the RV, it was 15.98 ± 3.88 mm, = 0.4199. The average angle of the entrance of the CS into the right atrium was 107.25° ± 9.68°. In the group with an RV impairment, it was 105.91° ± 9.22°, while in the patients with normal values of the RV, it was 108.82° ± 10.04°; = 0.0682. A multiple regression showed that end systolic volume ( = 0.0017) and stroke volume ( = 0.0144) are important predictors of the CS ostium.
Some relationships were found between the CS and the selected parameters that describe the function of the RV. This may suggest a role for the CS as a right ventricular buffer, which could potentially be treated as a marker of an RV impairment.
本研究旨在评估冠状动脉窦（CS）参数对使用心脏计算机断层扫描（CT）计算的右心室（RV）功能参数的影响。
对 150 例疑似冠心病患者进行心脏 CT 扫描，使用西门子 Somatom Force（2×192×0.6）和 syngo.via 工作站。以毫米（mm）测量 CS 口的“CT 冠状动脉”和在某些情况下的通用预设。使用 256×256 矩阵上的“CT 心脏功能”自动功能检查右心心室的功能测量。
CS 口的平均直径为 16.29±4.37mm。在 RV 功能障碍组中，直径为 16.56±4.76mm，而在 RV 值正常组中，直径为 15.98±3.88mm，=0.4199。CS 进入右心房的入口平均角度为 107.25°±9.68°。在 RV 功能障碍组中，角度为 105.91°±9.22°，而在 RV 值正常组中，角度为 108.82°±10.04°；=0.0682。多元回归显示，收缩末期容积（=0.0017）和每搏量（=0.0144）是 CS 口的重要预测指标。
发现 CS 与描述 RV 功能的选定参数之间存在一些关系。这可能表明 CS 作为 RV 缓冲器的作用，可将其视为 RV 损伤的标志物。
