Objectives: Left atrial appendage occlusion (LAAO) at the time of implantation may reduce thromboembolic events (TEs) during continuous-flow left ventricular assist device support. The HeartMate 3 (HM3) reduces TEs overall, but the efficacy of LAAO in HM3 is unknown.
Methods: Adults receiving first HM3 implantation from November 2014 through December 2019 at a single, large medical centre were retrospectively reviewed. TEs included device thrombosis and ischaemic stroke. Patients were classified by whether they received LAAO or not. Incidence of TEs was compared between groups using cumulative incidence curves with competing risks (death and heart transplant) and risk factors for TEs were assessed with Fine and Gray competing risk regression.
Results: A total of 182 patients received HM3, of whom 99 (54%) received LAAO versus 83 (46%) who did not. There were 14 TEs, including 13 strokes (7%) and 1 pump thrombosis (0.5%). No significant difference in the incidence of TEs in each group was found (Gray's test: P = 0.35). LAAO was not associated with TEs in multivariable Fine-Gray analysis (P = 0.10) and no significant risk factors for TEs were found. There were zero disabling strokes in those who received LAAO compared to 6 (7%) in those who did not receive LAAO (P = 0.008).
Conclusions: A low number of TEs was observed in HM3 recipients. LAAO did not further reduce the overall rate of TEs in this patient population, though its use may be beneficial in preventing disabling ischaemic strokes after HM3 implantation.

Background: Interventional left atrial appendage occlusion (LAAO) was developed as a treatment option for patients who cannot receive traditional anticoagulation therapies. To date, randomized study data on this treatment are still limited, so registries and other non-randomized studies may help define the role of LAAO in clinical practice.
Design: We performed LAAO consecutively on 599 patients.

: Chronic kidney disease (CKD) is a significant risk factor for thrombogenic and bleeding events in patients with atrial fibrillation (AF). Left atrial appendage occlusion (LAAO) is increasingly utilized as an alternative to oral anticoagulation. We aimed to compare LAAO against medical therapy in advanced CKD patients (A-CKD).

Background: Direct current cardioversion (DCCV) is commonly used for rhythm control in atrial fibrillation (AF). Left atrial appendage occlusion (LAAO) provides stroke prevention in patients with contraindications to oral anticoagulation (OAC), but the safety of DCCV without periprocedural anticoagulation in this group remains uncertain.
Objective: To evaluate the safety of performing DCCV without systemic anticoagulation in patients with prior LAAO.

Introduction: Myxomatous mitral valve disease (MMVD) is a prevalent cardiac condition in older, small-breed dogs, often managed with multiple medications. Traditional administration involves compounded powdered mixtures, which may lead to dosing inaccuracies and reduced compliance.
Methods: In a randomized, double-blind clinical trial, 60 client-owned dogs diagnosed with ACVIM stage C MMVD were assigned to receive either a novel fixed-dose combination tablet (Sentorphil ForteGold) or a compounded powdered mixture of torsemide, pimobendan, enalapril, and spironolactone.

Background: Atrial fibrillation (AF) ablation and left atrial appendage occlusion (LAAO) are traditionally performed in centers with onsite cardiothoracic surgery (CTS), expanding these procedures to centers without CTS (Wo-CTS) raises questions about procedural safety and feasibility.
Objective: To compare the safety and feasibility of AF ablation and LAAO at two centers within the Naples Comprehensive Healthcare (NCH) System in Southwest Florida, one with CTS and the other Wo-CTS.
Methods: A retrospective cohort study was conducted for consecutive patients between March 1, 2023, to May 31, 2025.
