新一代国产冠脉液电冲击波球囊导管应用于重度冠脉钙化病变的初步尝试

Preliminary trail of domestic coronary hydroelectric shockwave balloon catheter in managing severe calcified lesions

目的探讨新一代国产冠脉液电冲击波球囊导管治疗重度冠脉钙化病变的有效性和安全性。方法选择2021年12月1日至2021年12月31日复旦大学附属中山医院收治的3例重度冠脉钙化患者,应用Sonico-CX冠脉液电冲击波球囊导管对钙化病变进行预处理,以4 atm(1 atm=101.325 kPa)充盈扩张并释放10个脉冲后,加压至8 atm持续扩张10 s,同一钙化部位重复2~4次。结果国产冠脉液电冲击波球囊导管能有效扩张重度冠脉钙化病变,有助于后续支架植入。患者围手术期未出现手术并发症。结论国产冠脉液电冲击波球囊导管操作简单,能安全有效地扩张重度钙化病变,可作为重度冠脉钙化病变的治疗选择。

Objective To explore the efficacy and safety of domestic coronary hydroelectric shockwave balloon catheter in managing severe calcified lesions.Methods From December 1,2021 to December 31,2021,3 patients with severe coronary calcification lesions in Zhongshan Hospital,Fudan University were collected.Sonico-CX coronary hydroelectric shockwave balloon catheter was used to pretreat the calcified lesions.The balloon catheter was filled and expanded at 4 atm(1 atm=101.325 kPa)with 10 pulses,and then it was expanded at 8 atm for 10 seconds with 2-4 times were repeated at the same calcified site.Results Domestic coronary hydroelectric shockwave balloon catheter could effectively dilate severe coronary calcification sites,which was helpful for subsequent stent implantation,and no surgical complication was found during the perioperative period.Conclusion The domestic coronary hydroelectric shockwave balloon catheter is simple to operate and it could effectively dilate severe coronary calcification,which can be used as a treatment option for severe coronary calcified lesions.
