Isolated aortic valve diseases can lead to atrial fibrillation (AF) by causing left atrium pressure overload and enlargement. At present, most patients with preoperative AF and isolated aortic valve disease have undergone a Cox-maze IV procedure through a left atriotomy under cardiopulmonary bypass with aortic cross-clamping. Here, we describe a novel modified epicardial radiofrequency ablation procedure performed on a beating heart without aortic cross-clamping or opening the left atrium. This technique has proved to be safe and feasible, with good clinical outcomes. It may be useful in selecting the best ablation approaches for patients with AF and aortic valve disease.

Background: Little is known about the very long-term outcome in Tetralogy of Fallot (ToF) patients.
Objectives: To prospectively evaluate clinical outcome and quality-of-life after surgical repair of ToF.
Methods: Single-centre, longitudinal cohort-study evaluating every decade 144 ToF patients who underwent surgical repair <15 years of age between 1968 and 1980.

Background: The long-term outcomes of combined rapid-deployment aortic valve replacement (RDAVR) with coronary artery bypass graft surgery (CABG) are not well explored. We report 3-year results from the INCA registry on combined RDAVR with CABG.
Methods: INCA is a prospective, multicenter registry that enrolled 224 patients undergoing RDAVR with CABG at 10 cardiac institutions in Germany.
Clinical value of aortic arch morphology in transfemoral TAVR: artificial intelligence evaluation.

Background: The impact of aortic arch (AA) morphology on the management of the procedural details and the clinical outcomes of the transfemoral artery (TF)-transcatheter aortic valve replacement (TAVR) has not been evaluated. The goal of this study was to evaluate the AA morphology of patients who had TF-TAVR using an artificial intelligence algorithm and then to evaluate its predictive value for clinical outcomes.
Materials And Methods: A total of 1480 consecutive patients undergoing TF-TAVR using a new-generation transcatheter heart valve at 12 institutes were included in this retrospective study.

Background: Access-related vascular complications (VCs) after percutaneous transfemoral transcatheter aortic valve replacement (TAVR) are associated with poor clinical outcomes and remain a significant challenge despite technological advances. The aim of this study was to identify anatomic predictors of access-related VCs after TAVR on preprocedural contrast-enhanced multidetector computed tomography (MDCT).
