Multimodality Evaluation of LAA Leaks Arising After Incomplete LAAC: Insights From the LAA-Leak Registry

NCT05131308 | Completed Results

• 1 other identifier: KCHRF-LAA Leak Registry-0007
• Study Type: observational
• Target: 160
• Locations: 1 country
• Sites: 1

Brief Summary

Closure of peri-device leaks (PDL) after incomplete LAAC have shown early feasibility, however no comparison study of all the leak closure modalities exists. Therefore, this is an attempt to report the first 3-way observational comparison study to date, with results in 160 total patients in 3 arms including detachable embolization coils, vascular plugs/septal occluders and Radiofrequency ablation.

Conditions

Left Atrail Appendage Closure: Peri-device Leaks

Keywords

Left Atrial Appendage Closure; Central or peri-device leaks

Outcome Measures

Primary Outcomes (1)

• Size of PDL After Leak Closure Procedure

  Size of leak in mm on TEE after leak closure procedure, immediately at the end of the procedure and at 1 year follow-up

  Immediate postprocedural and 1 year follow-up

Secondary Outcomes (2)

• Periprocedural Complications Occurring From Postoperative Day 0 - Day 7

  From postoperative day 0 to day 7

• Delayed Procedure-related Complications at 1 Year Follow-up

  1 year after procedure

Study Arms (3)

Detachable embolization coils group

Patients who have an intervention for leak closure with detachable embolization coils

Other: leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA

Vascular plugs/septal occluders group

Patients who have an intervention for leak closure with vascular plugs/CSO

Other: leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA

RF Ablation group

Patients who have an intervention for leak closure with Radio Frequency Ablation (RFA)

Other: leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA

Interventions

leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA OTHER

All patients were evaluated and followed with imaging, and per investigators' respective clinical judgement, then proceeded to have an intervention for leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA.

Detachable embolization coils group; RF Ablation group; Vascular plugs/septal occluders group

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

All patients at risk for stroke or thromboembolism that demonstrated any degree of the significant leak on follow up TEE imaging at least 4-6 weeks following either epicardial, endocardial, or surgical LAAC were included in this study population. All patients were evaluated and followed with imaging, and per investigators' respective clinical judgement, then proceeded to have an intervention for leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA.

You may qualify if:

• Patients at risk for stroke or thromboembolism that demonstrated any degree of the significant leak on follow up TEE imaging at least 4-6 weeks following either epicardial, endocardial, or surgical LAAC
• Patients undergoing any form of eccentric or centric/central leak closure with available modalities (detachable embolization coils, vascular plus/septal/ASD occluders, or RF Ablation). Criteria for this was made based on the judgement of the operator, with no specific cutoffs for leak size, follow-up time from LAAC to leak closure, etc)
• Age greater than 18 years

You may not qualify if:

• Patients not undergoing leak closure after incomplete LAAC
• Patients unable to complete 45 day follow-up imaging for reevaluation of LAA leak
• Patients unable to consent
