Article Abstract
Aims: Video-assisted thoracoscopic surgery (VATS) ablation has been advocated as a treatment option for non-paroxysmal atrial fibrillation (AF) in recent guidelines. Real-life data on its safety and efficacy during a centre's early experience are sparse.
Methods And Results: Thirty patients (28 persistent/longstanding persistent AF) underwent standalone VATS ablation for AF by an experienced thoracoscopic surgeon, with the first 20 cases proctored by external surgeons. Procedural and follow-up outcomes were collected prospectively, and compared with 90 propensity-matched patients undergoing contemporaneous catheter ablation (CA). Six (20.0%) patients undergoing VATS ablation experienced ≥1 major complication (death n = 1, stroke n = 2, conversion to sternotomy n = 3, and phrenic nerve injury n = 2). This was significantly higher than the 1.1% major complication rate (tamponade requiring drainage n = 1) seen with CA (P < 0.001). Twelve-month single procedure arrhythmia-free survival rates without antiarrhythmic drugs were 56% in the VATS and 57% in the CA cohorts (P = 0.22), and 78% and 80%, respectively given an additional CA and antiarrhythmic drugs (P = 0.32).
Conclusion: During a centre's early experience, VATS ablation may have similar success rates to those from an established CA service, but carry a greater risk of major complications. Those embarking on a programme of VATS AF ablation should be aware that complication and success rates may differ from those reported by selected high-volume centres.

Surgical Outcomes of Video-Assisted Thoracic Surgery Combined With Computed Tomography-Guided Microwave Ablation for Lung Cancer Presenting as Multiple Ground-Glass Opacities: A 5-Year Retrospective Cohort Study.

Background: Multiple ground glass opacities (mGGOs) are frequently observed in patients with early-stage lung adenocarcinoma. The most appropriate and effective treatment for these mGGOs remains controversial. The purpose of this study was to retrospectively review the usefulness and safety of performing video-assisted thoracic surgery (VATS) combined with computed tomography (CT)-guided microwave ablation (MWA) in patients with synchronous multiple primary lung cancer (sMPLC) and to demonstrate the long-term surgical outcomes at our institute.

Objectives: Transbronchial microwave ablation may have additional value when performed with the same-session lung resection or in patients with a history of lung resection(s). We present our institutional cohort to assess the feasibility and safety of transbronchial microwave ablation with the presence of lung resection.
Methods: From March 2019 to February 2024, 92 patients who underwent transbronchial microwave ablation with either a history of major lung resection(s) or same-session ablation with concomitant video-assisted thoracoscopic lung resection(s) were included in this study.

Increased public health awareness and expanded low-dose computed tomography (CT) utilization, accelerated by the COVID-19 pandemic, have elevated detection rates of pulmonary ground-glass nodules (GGNs). Patients with multiple primary lung cancer (MPLC) often present with multiple GGNs, posing challenges for precise treatment and prognostic assessment. Current therapies including stereotactic body radiation therapy (SBRT), chemotherapy, and immunotherapy face efficacy and safety limitations.

Objective: To analyze trends in Medicare volume and utilization for percutaneous ablation of lung masses compared to sub-lobar surgical lung resection.
Methods: Claims from the Medicare Part B Physician/Supplier Procedure Summary from 2012 to 2021 were extracted using Current Procedural Terminology (CPT) codes for percutaneous lung thermal ablation (radiofrequency (RFA) and microwave) and cryoablation as well as open and Video Assisted Thoracoscopic (VATS) sub-lobar lung resection.
Results: The volume of lung mass ablation decreased from 601 cases (thermal ablation only) in 2012 to 466 cases (240 RFA and 226 cryoablation) in 2021 amongst Medicare beneficiaries.
