“…24 To achieve the best outcome and to minimize the risk of complications, it is still recommended to try to visualize the coronary venous system prior to invasive interventions. 25 Coronary venous system anatomy is relevant not only during cardiac resynchronization therapy implantations but also during electrophysiology studies as well as ablation inside the venous system. Operators must always keep in mind that the oblique vein may be a site for inadvertent cannulation by guidewires, diagnostic electrophysiology catheters, and left ventricular pacing electrodes, posing a risk of coronary venous system perforation and pericardial effusion or tamponade.…”

BackgroundThe oblique vein of the left atrium is of interest for electrophysiologists working in the field of both basic science and clinical practice. aims We aimed to examine the topographic anatomy of the oblique vein and to assess the vein's location and relationships with surrounding cardiac structures. methods A total of 200 autopsied adult human hearts were examined. results The oblique vein was observed in 71% of the hearts. Its mean (SD) total length was 30.8 (13.6) mm. In hearts with the oblique vein, a larger distance was observed between the left inferior pulmonary vein (LIPV) and great cardiac vein (mean [SD], 18.6 [5.1] mm vs 16.3 [4.8] mm; P = 0.004), between the left atrial appendage (LAA) and LIPV (mean [SD], 17.8 [6.8] mm vs 15.1 [5.2] mm; P = 0.007), and between the LAA and left superior pulmonary vein (LSPV; mean [SD], 28.5 [7.2] mm vs 21.3 [6.4] mm; P <0.001). Hearts with a classic pattern of left -sided pulmonary veins were categorized into 4 types based on the length of oblique vein extension. In type I, the vein extended below the level of the LIPV (21.9%); in type II, to the level of the LIPV (47.7%); in type III, to the level of the interpulmonary area (17.2%); and in type IV, to the level of the LSPV (13.3%). In each type, the distance between the oblique vein and LIPV was shorter than that between the oblique vein and LAA. conclusions The oblique vein had a variable course and differing lengths of extension. The presence of the oblique vein was connected with a greater distance between the left -sided pulmonary veins and LAA.

“…In this study, we used transthoracic echocardiography to measure CS diameter at three sites. 3 Ominde et al measured CS diameter in cadavers and showed that the CS diameter decreased from the proximal to the distal part. 5 In our study, a decrease in diameter was also shown.…”

“…In adults, CS is a muscular tube, 2 to 3 cm in length and 1 cm in diameter, located about 1 cm above and parallel to the junction of the left atrium and ventricle. 1,3 Thebesian valve is a fold of endocardial tissue that forms the orifice of CS and is a remnant of the right embryonic sinoatrial junction valve. 4 Knowledge about the CS anatomy is essential due to its importance in different heart procedures such as percutaneous mitral annuloplasty, retrograde cardioplegia, and biventricular pacing.…”

Background: Coronary sinus dimension is an important factor for diagnosing some types of cyanosis as well as congenital heart diseases and insertion of some devices into the coronary sinus if required. This study was designed to access the diameter and Z-score of the coronary sinus among children under 18 years of age. Methods: In this cross-sectional study on 95 individuals, the coronary sinus diameter was measured by transthoracic echocardiography in the four-chamber view at the connection to the right atrium, middle part, and distal end. The linear regression equation was utilized to determine age-adjust reference values, Z-scores, and the relationship between the individuals’ coronary sinus diameter age, height, and body surface area. The study was conducted from March to July 2020 in Namazi hospital clinic of Shiraz University of Medical Sciences, Shiraz, Iran. Results: The mean age of the persons who entered this study was 5.87±4.25 years. The mean coronary sinus diameter was 4.91±1.29 mm at the site of connection to the right atrium, 4.50±1.44 mm at the middle part, and 3.74±1.32 mm at the distal end. Coronary sinus diameter correlates positively with the participants’ age, weight, height, and body surface area (P<0.001). Conclusion: Coronary sinus diameter significantly correlates with the age, height, and body surface area of the cases. These features are useful in diagnosing some congenital heart diseases and insertion of suitable devices through it.

“…Despite its great clinical significance, the presence of the VV cannot usually be assessed preoperatively, because standard clinical resources seem to not allow the visualization of intravenous heart valves . In our unique study, we aimed to determine if the MSCT could fill this void.…”

Introduction: To deliver accurate morphological descriptions of the Vieussens valve (VV) and to investigate whether this structure could be visualized using standard contrastenhanced electrocardiogram-gated multislice computed tomography (MSCT).Methods: A total of 145 human autopsied hearts and 114 cardiac MSCT scans were examined. Results:The VV was observed in both study groups, however, the detection rate was significantly worse in the MSCT examination (18.4% in MSCT vs 62.1% in cadavers, P < .0001). The VV height was larger in MSCT patients (2.8 ± 1.2 vs 5.4 ± 1.7 mm; P < .0001). No significant difference was found in the measured distance between the VV and the coronary sinus ostium between the two separate subgroups (27.3 ± 9.5 vs 24.4 ± 5.8 mm; P = .18). In autopsied material the most frequent valve location was the anterior wall of the coronary sinus (43.3%); the same was observed in MSCT scans (71.4%). Conclusion:The VV is a common heart structure, present in over 60% of humans, located mainly on the anterior and superior circuit of the coronary sinus, with relatively high morphological variability. Large VVs, which pose a significant obstacle in catheterization procedures, may be visualized using standard-protocol contrastenhanced cardiac MSCT.

Three-dimensional visualisation of coronary sinus ostium from the inside right atrium perspective

Abstract: Cardiac CT angiography is a useful method that permits the coronary sinus ostium and Thebesian valve to be visualised in vivo from the inside of the right atrium in a comparable manner.
