房间隔缺损（ASD）患者房性心动过速发生率高，导管消融（CA）常在经皮ASD闭合前进行。我们的目的是阐明CA对ASD大小的影响。我们分析了16例继发性ASD患者，他们有房性心动过速的房颤病史，并在房颤前后进行了房颤大小评估。房颤后ASD的大小明显减小。年龄越小、三尖瓣反流压梯度和肺动脉收缩压越低与房颤大小减小有关。这些因素对于制定经皮ASD闭合策略至关重要。
The prevalence of atrial tachyarrhythmia is high in patients with atrial septal defect (ASD), and catheter ablation (CA) is often performed before percutaneous ASD closure. We aimed to clarify the effect of CA on the ASD size. We analysed 16 patients with secundum ASD who had a history of CA for atrial tachyarrhythmia and underwent ASD size evaluation before and after CA. The size of ASD significantly decreased after CA. Younger age and lower tricuspid regurgitation pressure gradients and pulmonary arterial systolic pressures were associated with size reduction. These factors are crucial for making strategies of percutaneous ASD closure.
