The steerable catheter refers to the catheter that is manipulated by a mechanism which may be driven by operators or by actuators. The steerable catheter for minimally invasive surgery has rapidly become a rich and diverse area of research. Many important achievements in design, application and analysis of the steerable catheter have been made in the past decade. This paper aims to provide an overview of the state of arts of steerable catheters. Steerable catheters are classified into four main groups based on the actuation principle: (1) tendon driven catheters, (2) magnetic navigation catheters, (3) soft material driven catheters (shape memory effect catheters, steerable needles, concentric tubes, conducting polymer driven catheters and hydraulic pressure driven catheters), and (4) hybrid actuation catheters. The advantages and limitations of each of them are commented and discussed in this paper. The future directions of research are summarized.

Introduction: In patients with chronic coronary syndromes (CCS), the benefit of percutaneous coronary intervention (PCI) added to optimal medical therapy (OMT) remains unclear. The indication to PCI may be driven either by angiographic evaluation or ischemia assessment, thus depicting different potential strategies which have not yet been thoroughly compared.
Methods: Randomized controlled trials (RCTs) comparing OMT versus PCI angio-guided or versus PCI non-invasive or invasive ischemia guided were identified and compared via network meta-analysis.
Impact of pulmonary vein isolation on atrial arrhythmias in patients with typical atrial flutter: systematic review and meta-analysis of randomized clinical trials.

Aims: Cavotricuspid isthmus (CTI) ablation is the current ablation treatment for typical atrial flutter (AFL). However, post-ablation atrial tachyarrhythmias, mostly in the form of atrial fibrillation (AF), are frequently observed after CTI ablation. We aimed to evaluate the effectiveness and safety of concomitant or isolated pulmonary vein isolation (PVI) in patients with typical AFL scheduled for ablation.

Endovascular interventions are procedures designed to diagnose and treat vascular diseases, using catheters to navigate inside arteries and veins. Thanks to their minimal invasiveness, they offer many benefits, such as reduced pain and hospital stays, but also present many challenges for clinicians, as they require specialized training and heavy use of X-rays. This is particularly relevant when accessing (i.

Background: The impact of below-the-knee (BK) runoff after drug-coated balloon (DCB) treatment in femoropopliteal (FP) lesions has not been well investigated.
Methods: This retrospective multicenter observational study enrolled 291 consecutive patients with lower extremity artery disease who underwent endovascular therapy with DCBs for FP lesions between January 2018 and December 2021. Patients were classified into four groups based on the BK runoff.

Introduction: Catheter ablation of persistent atrial fibrillation yields sub-optimal success rates partly due to the considerable heterogeneity within the patient population. Identifying distinct patient phenotypes based on post-ablation prognosis could improve patient selection for additional therapies and optimize treatment strategies.
Methods: We studied all patients who underwent catheter ablation of persistent atrial fibrillation in the DECAAF II trial.
