Posterior vein of left ventricle (accompanies the left marginal artery, ascends the posterior wall of left ventricle to drain into the coronary sinus); [6] Oblique vein of left atrium. [1] All veins that empty into the coronary sinus except for the oblique vein of the left atrium have valves at their junction with the coronary sinus. [1]
Rotation of the catheter to a "home view" of the left atrium through the mitral valve into the left ventricle. From there, a 180° rotation will face the posterior wall and posterior deflection will bring the left atrial appendage into view and can be used for deployment of a left atrial appendage occlusion device.
The interatrial septum is a septum that lies between the left atrium and right atrium of the human heart.The interatrial septum lies at angle of 65 degrees from right posterior to left anterior because right atrium is located at the right side of the body while left atrium is located at the left side of the body. [1]
Humans have a four-chambered heart consisting of the right and left atrium, and the right and left ventricle. The atria are the two upper chambers which pump blood to the two lower ventricles. The right atrium and ventricle are often referred to together as the right heart, and the left atrium and ventricle as the left heart.
The pulmonary artery and aorta are located in front of the left atrium. The left atrium is slightly smaller than the right atrium and consists of the venous component, which receives saturated blood from the lungs via four pulmonary veins, the vestibule, and a narrow appendage. The venous component forms a large part of the posterior wall of ...
From the right atrium, visualization of the interatrial septum, all four cardiac chambers, all four valves, and the pericardial space (for an effusion) can be readily visualized. It can also be advanced across the atrial septum into the left atrium to visualize the left atrial appendage during left atrial appendage occlusion device deployment.
The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left circumflex. The left anterior descending artery perfuses the interventricular septum and anterior wall of the left ventricle. The left ...
The left circumflex artery follows the left part of the coronary sulcus, running first to the left and then to the right, reaching nearly as far as the posterior longitudinal sulcus. There have been multiple anomalies described, for example the left circumflex having an aberrant course from the right coronary artery. [2]
