多层螺旋CT检查在显示心脏结构方面具有显著的优越性,目前被广泛用于心脏病的诊断、随访及相关研究。在心房颤动的导管消融治疗方面,现阶段多层螺旋CT检查的作用主要包括:清晰显示左心房/肺静脉的三维解剖结构;术前探查有无左心耳血栓;左心房与食管空间解剖关系的评估;随访期肺静脉狭窄的诊断;以及探讨心房颤动的机制等。 Multi-slice spiral CT examination has obvious advantages in displaying the structure of the heart and is widely used in the diagnosis, follow-up and related research of heart disease. In the treatment of atrial fibrillation catheter ablation, the role of multi-slice spiral CT at this stage mainly includes: clearly showing the three-dimensional anatomy of the left atrium / pulmonary vein; preoperative exploration of left atrial appendage thrombus; assessment of the relationship between left atrium and esophageal space anatomy ; Diagnosis of pulmonary vein stenosis during follow-up; and explore the mechanism of atrial fibrillation.
