    Abstract Aim: To report the clinical outcomes of thoracoscopic left atrial appendage occlusion (LAAO) with the AtriClip PRO2 device (Atricure Inc, Mason, OH, USA). Stroke risk reduction with LAAO in patients with atrial fibrillation is now well-established. Many surgical and percutaneous techniques have been used, with varying rates of success. The percutaneous devices have had issues with procedural complications and peridevice flow. Thoracoscopic AtriClip offers an epicardial linear closure of the appendage at its ostium. This study sought to evaluate its safety and efficacy in achieving complete LAA closure.
    Method: This is a prospective series of thoracoscopic AtriClip PRO2 as a standalone procedure or a thoracoscopic AtriClip deployed as an adjunct to minimal access cardiac and thoracic surgery. Study ethical approval was granted by the hospital Human Research Ethics Committee.
    Results: In total, 144 thoracoscopic AtriClip procedures were conducted by a single surgeon from 2017 to 2022, 56 standalone and 88 concomitant. There was no mortality or major morbidities. A 100% success in complete LAA closure was observed, with 87% complete follow-up imaging. For patients that underwent standalone AtriClip after cessation of anticoagulation, no thromboembolic phenomena were seen in the 180 patient-years of follow-up.
    Conclusions: This study demonstrates that thoracoscopic placement of AtriClip is safe and effective in achieving consistent and complete LAAO. Future randomised trials will be useful to compare outcomes with percutaneous devices.

    Abstract Purpose: This paper represents the initial phase of a proposed operator-friendly semiautomatic method for positioning and directing an intravascular three-magnet tip catheter in the human heart using an electromagnetic system.
    Methods: A predictive computer algorithm based on a comprehensive mathematical model is developed, which accurately calculates the magnetic field generated by the electromagnet system as well as the magnetic torques and forces exerted on a three-magnet tip catheter, and generates the necessary electromagnet currents for arbitrary displacement and deflection of the catheter tip within a workspace of 128 × 128 × 128 mm.
    Results: We demonstrate the ability of the developed mathematical model to accurately position a three-magnet tip catheter within the 128 × 128 × 128 mm workspace of a 3D eight-electromagnet system.
    Conclusions: The ability of the developed mathematical model in predicting the displacement, direction, and deflection of the catheter tip as a function of the electromagnet current values has been verified through experimental results.

    Abstract Background: The BioMonitor 2 Pilot Study assessed the implantation procedure, the sensing amplitude and the remote monitoring transmission success rate of the second generation implantable cardiac monitor, the BioMonitor 2 (Biotronik, Berlin, Germany).
    Methods: This was a prospective, multi-centre, single-arm, non-randomised study involving seven operators in five sites across Australia. Data were collected at implantation, during clinic visits at 1 week and 1 month post-implantation, and through wireless remote monitoring.
    Results: Thirty patients with indications for long-term cardiac monitoring underwent successful insertion of a study device. The median implantation time was 9 minutes (interquartile range (IQR) 5-14 mins). The mean R-wave amplitude at 1 week was 0.75±0.39mV and remained stable over the follow-up period. Within 1 day, 97% of the patients connected to the remote monitoring network and daily messages were transmitted on 93.8% of all study days. Seventy-six per cent of patients transmitted at least one subcutaneous ECG (sECG), with a median number of sECGs per patient of seven (IQR 3-37) within 28 days.
    Conclusions: The results of the BioMonitor 2 Pilot study confirm the excellent sensing amplitudes afforded by this new device and the utility of the implantation tools and technique. Patient compliance with and the transmission success rate of the home monitoring system were excellent.
