Incidental discovery of sinus venosus atrial septal defect (SV-ASD) in the elderly is rare. This defect allows for lead malpositioning during pacemaker placement and can lead to catastrophic cardioembolic events. Post-pacemaker implantation, chest radiography should be obtained to detect malpositioning early, and if detected, lead adjustment is recommended; if identified later, treatment with an anticoagulant is feasible. SV-ASD repair may be considered as well.
老年人偶然发现静脉窦型房间隔缺损(SV-ASD)的情况较为罕见。这种缺损会在起搏器植入过程中导致电极位置不当,并可能引发灾难性的心源性栓塞事件。起搏器植入术后,应进行胸部X线检查以便早期发现电极位置不当,若检测到该情况,建议调整电极;若后期才发现,则可行抗凝治疗。也可考虑对SV-ASD进行修复。
