Although results showed less compression when compared with that of the control group, custom tray relief of 1.0 mm and 3.0 mm over the anterior residual alveolar ridge and median palatal suture did not significantly impact the resulting impression topography when compared with no relief custom trays. The study objective was to determine whether mini-invasive transthoracoscopic atrial fibrillation ablation can delay the progression of atrial fibrillation from paroxysmal to persistent. Patients aged 18 to 80years with paroxysmal nonvalvular atrial fibrillation and a history of stroke or systemic thromboembolism were consecutively enrolled from September 2014 to June 2019. In the treatment group, patients underwent transthoracoscopic atrial fibrillation ablation plus left atrial appendage excision (atrial fibrillation ablation plus left atrial appendage excision group). Patients unwilling to receive surgical intervention were treated with antiarrhythmic drugs and oral anticoagulants and recruited as a control group (atrial fibrillation plus antiarrhythmic drugs group). The primary end point was the progression of atrial fibrillation from paroxysmal to persistent. This study included 49 patients in the atrial fibrillation plus antiarrhythmic drugs group (29 men) and 77 patients in the atrial fibrillatiot be especially suitable for patients with paroxysmal nonvalvular atrial fibrillation at high risk of stroke and high risk of bleeding. Patients with paroxysmal nonvalvular atrial fibrillation who chose to undergo transthoracoscopic atrial fibrillation ablation had a lower incidence of progression to persistent atrial fibrillation than patients who chose conservative therapy. This strategy might be especially suitable for patients with paroxysmal nonvalvular atrial fibrillation at high risk of stroke and high risk of bleeding.A recent study in non-human primates (NHPs) by Panichello and Bus
