“…Regarding the cs, it is evidenced that it is one of the structures more fully described, both in humans [5,14,16,17] and pigs [1,4,11]. In humans its caliber reported at 6.12 mm [5], compared to the caliber this structure proximal anatomical pieces studied 10.9 mm for the proximal and 12.36 mm for distal caliber.…”

Abstract. Introduction:Similarities between the bodies of pigs and humans have encouraged studies in comparative anatomy, trying to describe in detail the anatomical variations that could influence in the xenotransplantation; given that advances in genetics, immunology and biotechnology are large, this possibility is not far. The objective of this work was to make contributions to the vascular study of porcine heart. Methodology: 60 porcine hearts, with an average of five months old and weighing 85-95kg, were obtained from plant Vijagual. After receipt hearts were kept in water for six hours, then they were perfused with polyester resin semi-synthetic and mineral blue color, moreover the left coronary artery was perfused with red mineral color. Subsequently, the hearts were subjected to a process of partial corrosion with potassium hydroxide (15%), then the coronary sinus and its tributary branches were dissected from its origin to its distal segments, path, shapes, sizes, anastomosis and presence of registered anatomical variations. Photographic record of the samples was performed. Results: The origin of the distal caliber of Great cardiac vein (5.36 +/-1,04mm) was determined from the apex at 70% of anatomical pieces studied, and the ventricular groove paraconal in 30% of the pieces analyzed. The arteriovenous trigone was found in 58 of the cardiac structures studied (96.66%). Conclusion: The description of the anatomic variations present in the pig heart structure will contribute to the possibility of xenotransplantation and also provides data for the development of studies on cardiovascular surgery and certain diseases of clinical and epidemiological importance.Keywords: cardiac circulation, comparative anatomy, coronary sinus, heart, venous circulation. Estudio del seno coronario y sus tributarias en cerdos Resumen. Introducción: las similitudes entre el cuerpo del cerdo y el del ser humano han fomentado estudios de anatomía comparada que intentan describir en detalle las variaciones anatómicas que podrían tener influencia en los xenotrasplantes. Teniendo en cuenta que los avances en genética, inmunología y biotecnología son grandes, esta no es una posibilidad lejana. El objetivo de este trabajo era contribuir al estudio vascular del corazón porcino. Metodología: 60 corazones porcinos, con un promedio de cinco meses de edad y un peso de 85-95 kg, se obtuvieron de la planta Vijagual.

Además, la arteria coronaria izquierda se perfundió con color rojo mineral. Posteriormente, los corazones se sometieron a un proceso de corrosión parcial con hidróxido de potasio (15%) y, luego, el seno coronario y sus ramas tributarias fueron disecados desde su origen hasta sus segmentos distales, registrando trayectorias, formas, tamaños, anastomosis y presencia de variaciones anatómicas.

“…Overall, retrograde coronary sinus angiography offered a better display of target vessels commonly used for LV lead implantation. Imaging of the coronary sinus via cardiac computed tomography correlates well with direct coronary sinus venography (Van de Verie et al, 2006). Imaging of the coronary venous anatomy by computed tomography is non-invasive and can help to plan coronary sinus lead implantation especially in patients with angulated coronary veins and in patients in whom a left marginal vein or a posterior vein is absent.…”

“…Implantation with cardiac resynchronization therapy will be successful only if the left ventricle lead can be positioned in a vein that drains this region. The left marginal vein and the posterolateral vein are often the target veins involved in pacemaker lead placement in cardiac resynchronization therapy (48,49).…”

261C oronary artery disease is responsible for millions of deaths per year in developed countries (1, 2). Early recognition of coronary artery disease is important for the prevention of its related complications and improving prognosis (3). Catheter angiography has been considered the gold standard imaging method for evaluating the coronary tree. The major advantages of conventional coronary angiography (CCA) are its high spatial and temporal resolutions and the option of directly performing interventions, such as balloon dilation or coronary stent placement (4). However, CCA is an invasive procedure that carries the risk of morbidity and mortality (3). In addition, CCA provides only luminal data and is limited in revealing changes in the vessel wall and the adjacent soft tissues. Conversely, multidetector computed tomography coronary angiography (MDCT-CA) not only provides visualization of the vessel lumen but also displays the vessel wall and surrounding soft tissues, allowing for the detection of various congenital or acquired abnormalities of the coronary arteries that may not be evident with CCA (3).In this article, on the basis of our experience with more than 15 000 MDCT-CA from seven different centers, we reviewed clinical conditions in which MDCT-CA may be more helpful compared with CCA. Coronary CT techniqueWith the advent of technological refinements in the last decade, MDCT-CA has gained widespread use for the evaluation of coronary artery diseases. Currently, state-of-the-art computed tomography (CT) systems can simultaneously acquire 64 or more submillimeter sections with a gantry rotation time of less than half a second. Previous limitations of CT for evaluating the vascular system, associated with older generation scanners, have now been eliminated. Presently, a thinner section thickness allows for isotropic voxels, which is essential for optimum high-resolution, three-dimensional (3D) reconstruction and other postprocessing displays, such as maximum projection reformatting (MPR) in any selected plane. Faster scanners have resulted in shorter scans and shorter contrast bolus durations, allowing for the use of less contrast agent at a higher flow rate to achieve greater luminal enhancement. Motion artifacts from breathing are no longer a problem since highresolution imaging of the entire heart can be obtained in a single breath hold. Electrocardiography (ECG) gating techniques improve temporal resolution and minimize imaging artifacts caused by cardiac motion. With more recent technological advances, a reduction in radiation dose, for example, by the utilization of prospective gating, has occurred without any deterioration in diagnostic image quality (5).In our centers, images were acquired using either 16-or 64-MDCT scanners. Eighty-five to one hundred milliliters of iodinated contrast medium (Ultravist 370, Schering, Berlin, Germany) was intravenously ABSTRACT In this review, we aimed to outline the clinical and pathological conditions for which multidetector computed tomography coronary angiogr...

Non-Invasive Visualization of the Cardiac Venous System in Coronary Artery Disease Patients Using 64-Slice Computed Tomography

Abstract: Non-invasive evaluation of cardiac veins with 64-slice CT is feasible. There is considerable variation in venous anatomy. Patients with a history of infarction were less likely to have a LMV, which may hamper optimal left ventricular lead positioning in CRT implantation.
