心房颤动射频消融治疗前后肺静脉形态结构CT成像改变的临床研究
CT imaging change of pulmonary vein morphology in atrial fibrillation patients before and after radiofrequency ablation
摘要
Abstract
Objective To observe the morphological changes of circumferential pulmonary vein ahlation (CPVA) for atrial fibrillation (AF) on the structure of pulmonary vein before and after radiofrequency ablation hy CT three-dimensional image technique. Method 28 patients with AF who underwent CPVA were followed-up after (6.5 ± 3.9) months. The patients were divided into 2 groups : successful group (22 patients) and recurrence group (6 patients) arcording to the recurrence of AF. Analyze the differences between preoperative and postoperative pulmonary vein morphology. Pulmonary vein diameters , cross-sectional area and left atrial volume were measured before and after CPVA using 64-slice multidector computed tomography (CT). Result In successful group, compared with preablation, left upper pulmonary vein maximum diameter, right upper pulmonary vein maximum diameter, right upper pulmonary minimum diameter, right lower pulmonary vein maximum diameter, right lower pulmonary minimum diameter, the four pulmonary vein cross-section areas and left atrial volume were reduced (P ＜ 0.05) after CPVA, while there were no significant difference in left upper pulmonary minimum diameter, left lower pulmonary vem maximum diameter, left lower pulmonary minimum diameter (P ＞ 0.05). In recurrence group, compared with preahlation, right lower pulmonary vein maximum diameter, left lower pulmonary vem cross-section areas and right lower pulmonary vein cross-section areas were reduced (P ＜ 0.05) after CPVA, while other pulmonary mimmum indexes and left atrial volume were no significant difference (P ＞ 0.05). Stenosis of pulmonary vein maximum diameter and pulmonary mimmum diameter less than 50％ respectively were 61.6％ and 56.3％ after CPVA. Stenosis reached 50％ and 70％ respectively were 3.6％ and 5.4％. Conclusions (1) The reconstruction of pulmonary vein and left atrial can be reversed after CPVA in patients with AF, while there is no significantly reverse remodeling in the recurrence group. (2) Some patients may suffer asymptomatic pulmonary vein stenosis after CPVA.关键词
