Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a heart cryoablation system. Background technique [0002] Atrial fibrillation is a common acquired cardiac arrhythmia in adults. According to reports, the total prevalence of atrial fibrillation among people over the age of 30 in my country is about 0.77%, and the prevalence will increase with age. For middle-aged and elderly patients, atrial fibrillation is usually associated with various heart diseases such as mitral regurgitation and atrial appendage thrombosis. According to the statistics of researchers, there are 33.5 million people suffering from atrial fibrillation in the world, and the number of patients with atrial fibrillation in my country has reached more than 10 million, accounting for 0.5% of the world's population. This latest epidemiological data confirms that "atrial fibrillation is a global epidemic." "The emergence of this situation. [0003] At pr...
