In surgical atrial septal defect (ASD) closure, there are no techniques or devices that can close the ASD accurately in a short time under a beating heart. We have developed a simple and automatic ASD closure technique using a circular stapler. This study assessed the feasibility and efficacy of a new circular stapler closure for ASD.
Under a continuous beating heart, hand-sewn patch plasty ASD closure was performed in 6 pigs (group A) and circular stapler ASD closure was performed in 6 pigs (group B). The time to close the ASD and the effectiveness of the closure were compared.
Closure was significantly faster in group B (10.5 ± 1.0 seconds) than in group A (664 ± 10 seconds; p < 0.05). There was no leakage at the closure site, and sufficient tolerance was confirmed.
A circular stapler can be used to treat ASD faster than hand-sewn patch plasty, with sufficient pressure tolerance in a beating heart porcine model.
在外科房间隔缺损（ASD）封堵术中，尚无技术或装置能够在心脏跳动的情况下短时间内准确封堵ASD。我们研发了一种使用圆形吻合器的简单自动ASD封堵技术。本研究评估了新型圆形吻合器封堵ASD的可行性和有效性。
在心脏持续跳动的情况下，对6头猪进行了手工缝合补片修补ASD封堵术（A组），对6头猪进行了圆形吻合器ASD封堵术（B组）。比较了封堵ASD的时间和封堵效果。
B组的封堵时间（10.5±1.0秒）明显快于A组（664±10秒；p<0.05）。封堵部位无渗漏，且确认有足够的耐受性。
在心脏跳动的猪模型中，使用圆形吻合器治疗ASD比手工缝合补片修补更快，且具有足够的压力耐受性。
