This analysis aimed to assess the procedural success rates of LAA occlusion (immediate and short-term outcomes) using the Amulet device, in patients with prior failed LAAO with W-FLX device.</p><p><strong>Methods and results: </strong>This was a multicentric retrospective analysis of 62 consecutive patients with unsuccessful LAAO with W-FLX, who subsequently underwent an attempted Amulet occluder placement. The primary endpoint was successful Amulet implantation. Secondary endpoints included peri-device leak (PDL) and device-related thrombus assessed by transesophageal echocardiography (TEE) at 45 days, safety end point through 7 days or hospital discharge (whichever was later) and major adverse events (MAEs) through 45 days. The Amulet occluder was successfully implanted in 98.38% of patients (n = 61/62). No clinically relevant PDL or device-related thrombus was noted at 45 days. There was one pericardial effusion noted a week after Amulet implant that underwent successful percutaneous pericardiocentesis. The reasons for W-FLX failure were all anatomical in nature.
