背景-这份报告描述了并发症的肺静脉狭窄，从而导致严重的肺动脉高压，在2例成功的导管消融术后的慢性房颤。方法和结果-三个月成功的导管消融术后的心房颤动，这两名患者发展进行性呼吸困难和肺动脉高压。两例患者均发现与左心房交界处附近的所有4条肺静脉严重狭窄。球囊扩张狭窄的肺静脉在这些patients中进行，改善呼吸困难和肺动脉高压。结论肺静脉狭窄的并发症是潜在的危及生命的，应避免使用标准导管技术的肺静脉内的射频电流的应用。这种并发症可以用球囊扩张治疗，但长期病程尚不清楚。
Background-This report describes the complication of pulmonary vein stenosis with resultant severe pulmonary hypertension that developed in 2 patients after successful catheter ablation of chronic atrial fibrillation.Methods and Results-Three months after successful catheter ablation of atrial fibrillation, both patients developed progressive dyspnea and pulmonary hypertension. Both were found to have severe stenosis of all 4 pulmonary veins near the junction with the left atrium. Balloon dilation of the stenotic pulmonary veins was performed in these patients, with improvement in dyspnea and pulmonary hypertension.Conclusions-The complication of pulmonary vein stenosis is potentially life-threatening, and the application of radiofrequency current within the pulmonary veins with standard catheter technology should be avoided. This complication can be treated with balloon dilation, although the long-term course is unknown.
