Percutaneous MitraClip intervention for treatment of severe mitral regurgitation in high surgical risk patients requires large-diameter transseptal sheaths that can result in iatrogenic atrial septal defect (iASD), and its prevalence is higher compared with non-MitraClip procedures. This iASD is not routinely closed because the possible consequences are still not fully understood. However, we believe it is important to identify patients who may benefit from its closure immediately after the procedure to prevent hemodynamic deterioration and long-term negative clinical outcomes. We describe our experience with 2 patients who required iASD closure after MitraClip procedure due to right-to-left shunt resulting from increase in right heart pressures.
经皮二尖瓣夹合术（MitraClip）介入治疗高危外科手术风险患者的重度二尖瓣反流需要使用大直径的经房间隔穿刺鞘，这可能导致医源性房间隔缺损（iASD），其发生率高于非 MitraClip 手术。通常不会常规关闭这种 iASD，因为其可能的后果尚未完全了解。然而，我们认为重要的是在手术后立即识别可能受益于其关闭的患者，以防止血液动力学恶化和长期的负面临床结局。我们描述了 2 例因右心压力增加导致右向左分流而在 MitraClip 手术后需要关闭 iASD 的患者的经验。
