Abstract | BACKGROUND: METHODS: This is a single-center prospective analysis of 369 patients who underwent LAAC from December 2016 to March 2022 at a large teaching hospital. We compared patients who developed effusion (n = 5) to patients who did not (n = 364) to determine if there were any factors that predispose patients to developing acute (AEs) or delayed pericardial effusions (DEs). We compared patient characteristics, procedural data, and complications. Unadjusted, stepwise multivariate logistic regression was performed. RESULTS: A total of 369 patients underwent LAAC. Of these, 5 patients (1.4%) developed pericardial effusion. Patients in both groups ( pericardial effusion vs non-effusion) had similar patient and procedural characteristics. Patients in both groups were older (mean age, 78.4 ± 7.8 years in the effusion group vs 76.3 ± 8.5 years in the non-effusion group; P=.50) and white (60% in the effusion group vs 90.1% in the non-effusion group). CHA2DS2-VASc (4.2 ± 1.1 vs 4.5 ± 1.4; P=.67) and HAS-BLED (3.4 ± 0.5 vs 3.7 ± 0.9; P=.53) scores were similar in the effusion group vs the non-effusion group, respectively. Gastrointestinal bleeding was the most common procedural indication in both groups (80% in the effusion group vs 53.6% in the non-effusion group; P=.23). The majority of the patients in both groups had successful implantation in the first attempt, with the 27-mm device the most commonly used size. There was no significant difference in procedural duration (67 minutes in the effusion group vs 75 minutes in the non-effusion group; P=.16). Among patients who received the Watchman Legacy device, 2 patients developed AEs and no patients had DEs. Of those receiving the Watchman FLX device, 1 patient developed AE and 2 patients developed DEs. All of the patients with effusions had successful recovery. CONCLUSION: In this 5-year, single-center experience, DEs were uncommon and potentially related to LAA device anchor microperforation. No statistically significant risk factors predisposing patients to pericardial effusions were identified in our analysis.
