Objectives: To assess the impact of WATCHMAN™ on quality of life (QoL) in octogenarians and nonagenarians.Background: QoL after WATCHMAN™ device in the elderly remains unknown.Methods: This is a prospective and retrospective cohort study of patients that underwent WATCHMAN™ implantation in a tertiary cardiovascular center from April 1, 2015 to September 27, 2017. The primary outcome was a prospective assessment of QoL via the SF-12v2 Health Survey (SF-12v2) in those aged ≥80 and ≥90 years. Secondary outcomes include major bleeding, stroke, vascular complications, pericardial effusion, device related thrombus (DRT), prolonged length of stay (LOS), acute kidney injury (AKI), and recurrent hospitalizations. Results: This cohort of 151 patients included 48/151 (32%) females with a mean age of 80 AE 7.7 years. Mean CHA 2 DS 2 -VASc was 4.38 AE 1.36 and mean HAS-BLED was 3.27 AE 1.17. Octogenarians 65/81(80%) and nonagenarians 16/81(20%) comprised 81/151(54%) of patients (mean age 86 AE 4.3 years) from which 36/65 (55%) octogenarians and 10/16 (63%) nonagenarians completed SF-12v2 evaluation at 22 AE 10 and 30 AE 10-months. Octogenarians demonstrated enhanced physical component scores (PCS), and nonagenarians equal PCS versus the age-adjusted norm (45.43 AE 9.84 versus 38.68 AE 11.04, P = 0.0003, and 41.26 AE 12.36 versus 38.68 AE 11.04, P = 0.6463, respectively). The mental component scores (MCS) of octogenarians and nonagenarians remained comparable (51.80 AE 9.56 and 48.97 AE 9.92 versus 50.06 AE 10.94, respectively, P = 0.4659). No stroke, vascular complications, pericardial effusions, or readmissions related to WATCHMAN™ occurred. No difference among patients <80, ≥80, and ≥90 years was found in major bleeding events, DRT, prolonged LOS, or AKI (P = 0.0569, 0.116, 0.498, and 0.795, respectively).Conclusions: Octogenarians and nonagenarians experience favorable long-term QoL after WATCHMAN™, with acceptable bleeding risk and low incidence of procedure-related complications.
