心房颤动的射频消融是心血管领域热门课题,传统的X线影像下的心房颤动射频消融尽管取得很大进展,但仍然有许多亟待解决的问题。心腔内超声技术的诞生和发展极大克服了放射影像下心房颤动射频消融的不足,拓展了心房颤动射频消融的空间。 Radiofrequency ablation of atrial fibrillation is a hot topic in the cardiovascular field. Although radiofrequency ablation of atrial fibrillation under the traditional X-ray image has made great progress, there are still many problems to be solved urgently. The birth and development of intracardiac ultrasound technology greatly overcome the shortcomings of radiofrequency ablation of atrial fibrillation under radiological imaging and expand the space for radiofrequency ablation of atrial fibrillation.
