VMEs into the PA and Ao beyond the VAJ are relatively common. It seems that their mere presence does not predispose to OT VTs. There are probably intrinsic arrhythmogenic properties in tissues specific to these regions in those patients who develop OT VTs.
The orbit is an essential anatomic landmark and orbital measurements are one of the craniofacial parameters that could be used in sexual and ethnic estimation in terms of anthropologic studies. The aim of this study is to obtain and analyze data regarding the computed scans of orbital aperture measurements in Turkish population for sex estimation and for comparing with other populations. A total of 112 Three-Dimensional Angiography Computed Tomography scans of 52 female and 60 male subjects aged between 13 and 86 years were examined in terms of Orbital Width (OW) and Orbital Height (OH). Sexual dimorphism was analyzed using by discriminant function models. It was determined that both left and right OW and OH of males were significantly larger than females. While single variable used for sexual dimorphism, the most confidential variable was the left OW for males (71.7%) and the left OH for females (69.2%). When combined models were used, the left OW and OH model was the best one for both males (80.0%) and females (69.2%). Data obtained from this study showed that orbital measurements could be used to create a new data collection for Turkish population. However, it was seen that these measurements are not reliable parameters for sex discrimination. It should be better, if they are combined with other methods for sex estimation.
Objective: Anatomical differences in coronary orifices (CO) are important as they are associated with myocardial ischemia and sudden death. The location of coronary orifices to the aortic valve has been studied since it is a determining point in surgical and radiological attempts. Methods: The number, position, and shape of the CO, and their relation to the sinotubular junction (SJ), were studied in 100 normal adult hearts. Student-t test, one-and two-way ANOVA with posthoc Tukey's HSD tests were applied for statistical analysis. Results: The mean height of the right, non-and left coronary sinuses were 18.75±1.71, 17.86±1.55 and 16.41±1.21 mm, respectively. The mean height of the right, non-and left coronary cusps were measured as 16.2±1.2, 15.9±1.1 and 12.3±2.1 mm, respectively. The left coronary artery (LCA) was observed to arise from the lower part of the SJ in 58% of the patients, while in 29% of them it originated from the SJ, and in 13% of the cases it arose from the upper part of the SJ. The right coronary artery (RCA) arising from the lower part of the SJ was seen in 78% of the patients, while it originated from the SJ in 13% of the patients, and it was observed to arise from the upper part of the SJ in 9 specimens. The diameters of the LCA and RCA were measured as 4.22±0.72 and 3.32±0.82 mm, respectively. An accessory orifice was found on the left in 47 specimens, while it was seen on the right in 54 of them. Conclusions: The location of the CO should be identified according to the vertical and horizontal surfaces of the sinus. In this study, the frequency of the coronary artery orifices with different locations was provided. Such data will increase the success of coronary interventions and decrease complication rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
