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.
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.
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.
本报告描述了2例慢性心房颤动成功导管消融术后发生肺静脉狭窄并导致严重肺动脉高压的并发症。
心房颤动成功导管消融术后3个月，2例患者均出现进行性呼吸困难和肺动脉高压。二者均被发现4条肺静脉在与左心房交界处附近存在严重狭窄。对这些患者进行了狭窄肺静脉的球囊扩张术，呼吸困难和肺动脉高压均有所改善。
肺静脉狭窄并发症有潜在生命危险，应避免使用标准导管技术在肺静脉内施加射频电流。尽管长期病程尚不清楚，但这种并发症可用球囊扩张术治疗。
