What is the trailer of the left atrium?
Left atrium pendant is a small structure that resembles a finger coming from the left atrium of the human heart. The pendant is filled with blood and releases blood into the left ventricle simultaneously with the left atrium. Although this structure is not necessary for survival, it plays a role in lowering blood pressure on the left side of the left atrium. Left atrium problems can in some cases lead to the removal of the left atrium.
The left atrial pendant is hollow and is filled with blood when it does the left atrium. The muscles in this attachment run parallel to the muscles in the left atrium. It is located on the top of the left atrioventricular groove. In heart surgery, this pendant must sometimes be moved from the way, as its location partially prevents access to the left coronary artery.
The magnitude of this annex changes in relation to the age and sex of a person. It is in the shape of a curved, elliptical tube and can have two or very hard lobes that come to its sides. The opening of this chamber is on average between 0.2 and 0.5 inches (about 0.6 and 1.2 cm). In general isBetween 0.8 and 1.1 inches (about 2.1 and 2.9 cm) long, although in some individuals it can measure up to 1.7 inches (about 4.5 cm) in length.
atrial fibrillation, which is an irregularity in the heart rhythm of a person caused by incorrect performance of an electrical pulse in one or both atrium, can cause problems in the left addition. This condition is responsible for about 25% of moves that are caused when blood flow to the brain is usually disturbed, usually through the blood of a clot that is stored in the artery leading to the brain. In patients with atrial fibrillation, blood may be collected in the left atrial pendant; If it relaxes, it can lead to a stroke. Some doctors recommend that you remove the left atrium pendant to prevent the death of the stroke.
people can easily survive without the use of a left atrial pendant. Patients who needed a mitral valve surgery often had this pendant removed as a routine part of this chiRurgy. At present, there is no evidence that the removal of this part of the heart adversely affects the heart function throughout the patient's life. Although this annex is applied, there is evidence that suggests that it can help in lowering blood pressure in the left atrium.
