What is the most common cause of cerebral embolism?

What is the most common cause of cerebral embolism? Please ask Chen Fei, deputy director of Xuanwu Hospital of Capital Medical University, to answer for you. Cerebral embolism often refers to cardiogenic cerebral embolism. Common causes include heart rhythm problems, arrhythmia, heart beats, and atrial fibrillation. There are also some other causes that can lead to cardiogenic embolism, such as congenital heart disease, atrial septal defect, and patent foramen ovale, which may lead to embolism. Similarly, if a cardiac myxoma grows on the heart, a cardiac infection forms endocarditis, and a vegetation grows, it may also cause emboli to fall off and lead to cerebral embolism.
