OBJECTIVES The aim of this study was to assess the feasibility and efficacy of transcatheter leak closure with detachable coils in patients with incomplete left atrial appendage (LAA) closure. BACKGROUND Incomplete LAA closure is common after interventional therapies targeting the LAA, potentially hindering effective thromboembolic prevention. Detachable coils have found a wide range of applications for transcatheter vascular occlusion and embolization procedures. METHODS Thirty consecutive patients at high thromboembolic risk with clinically relevant residual leaks (mean age 72 ± 9 years, 73.3% men, mean CHA2DS2-VASc score 4.4 ± 1.4, mean HAS-BLED score 3.6 ± 0.8) underwent percutaneous closure of the LAA patency using embolization coils. Transesophageal echocardiography was performed at 60 ± 15 days post-procedure. RESULTS LAA closure had been previously attempted with the Watchman device in 25 patients, the Amulet device in 2 patients, and the LARIAT device in 3 patients. Baseline transesophageal echocardiography documented moderate and severe leaks in 20 (66.7%) and 10 (33.3%) patients, respectively. After a single procedure, 25 patients (83.3%) showed complete LAA sealing or minimal leaks. Five patients (16.7%) had moderate residual leaks; 3 patients of them were offered repeat procedures. Mean procedure and fluoroscopy times were 76 ± 41 min and 21 ± 14 min, respectively; the mean volume of iodinated contrast medium used was 80 ± 47 ml. Coil deployment was successful in all cases. The overall complication rate was 6.1%. After a median follow-up period of 54 days (range 43 to 265 days) and an average of 1.1 procedures/patient, transesophageal echocardiography revealed complete LAA sealing or negligible residual leaks in 28 patients (93.3%; 25 with no residual leak, 3 patients with minimal to mild residual leaks) and moderate residual leaks in 2 patients (6.7%). CONCLUSIONS Transcatheter LAA leak occlusion using endovascular coils appears to be a safe, effective, and promising approach in patients at high echo time risk with incomplete LAA closure.

左心耳封堵术后可分离线圈经导管泄漏闭塞的初步经验。

目的本研究的目的是评估可分离线圈在不完全左心耳(LAA)闭合患者中经导管漏孔闭合的可行性和有效性。背景技术在针对LAA的介入治疗之后,不完全的LAA闭合很常见,可能会阻碍有效的血栓栓塞预防。可拆卸线圈在经导管血管闭塞和栓塞手术中发现了广泛的应用。方法连续30例具有高血栓栓塞风险并伴有临床相关残余渗漏(平均年龄72±9岁,男性73.3%,平均CHA2DS2-VASc评分4.4±1.4,平均HAS-BLED评分3.6±0.8)的患者接受了LAA的经皮封堵术使用栓塞线圈。手术后60±15天行经食道超声心动图检查。结果先前曾尝试用Watchman装置治疗25例患者,使用Amulet装置治疗2例,使用LARIAT装置治疗3例LAA。基线经食道超声心动图记录分别有20例(66.7%)和10例(33.3%)患者出现中度和严重渗漏。一次手术后,有25名患者(83.3%)表现出完全的LAA密封或渗漏最少。五名患者(16.7%)有中等程度的残余渗漏;他们中的3例患者得到了重复手术。平均手术时间和透视时间分别为76±41分钟和21±14分钟。使用的碘化造影剂的平均体积为80±47 ml。在所有情况下,线圈部署均成功。总体并发症发生率为6.1%。在中位随访期为54天(从43到265天),平均每位患者接受1.1次手术后,经食道超声心动图检查发现28例患者完全LAA封闭或残留漏气可忽略不计(93.3%; 25例无残留漏气,3例患者残留漏气至轻度至中度),2例患者中度残留漏气(6.7%)。结论对于有高回声时间风险且LAA关闭不完全的患者,使用血管内线圈进行经导管LAA渗漏闭塞似乎是一种安全,有效和有前途的方法。(在不完全的左心耳附件闭合手术之后[TREASURE]; NCT03503253,用可分离的线圈进行经导管的漏孔闭合)。结论对于有高回声时间风险且LAA关闭不完全的患者,使用血管内线圈行经导管LAA闭塞似乎是一种安全,有效和有前途的方法。(在不完全的左心耳附件闭合手术之后[TREASURE]; NCT03503253,用可分离的线圈进行经导管的漏孔闭合)。结论对于有高回声时间风险且LAA关闭不完全的患者,使用血管内线圈行经导管LAA闭塞似乎是一种安全,有效和有前途的方法。(在不完全的左心耳附件闭合手术之后[TREASURE]; NCT03503253,用可分离的线圈进行经导管的漏孔闭合)。
