Catheter ablation with remote magnetic navigation (RMN) can offer some advantages compared to manual techniques. However, the relevant clinical evidence for how RMN-guided ablation affects electrical storm (ES) due to ventricular tachycardia (VT) in patients with severe ischemic heart failure (SIHF) is still limited. ⋯ Acute catheter ablation with RMN is safe and effective to suppress ES in SIHF patients. RMN-guided catheter ablation can prevent VT recurrence and significantly reduce ICD shocks, suggesting that this strategy can be used as an alternative therapy for VT storm in SIHF patients with ICDs.

To evaluate diagnostic strategies in a rapid access chest pain clinic (RACPC) in the United Kingdom and to predict the economical and clinical impacts of incorporating fractional flow reserve by coronary computed tomographic angiography (FFRCT) into future pathways. ⋯ The DF algorithm overestimates the PTL of CAD supporting an extended role for coronary CTA. Strategies incorporating FFRCT may confer benefits in evaluating patients with stable chest pain.

Pulmonary endarterectomy (PEA) has been the most effective therapy for chronic thromboembolic pulmonary hypertension (CTEPH). However, residual or recurrent pulmonary hypertension often persists after PEA. Recently, catheter-based angioplasty, called percutaneous transluminal pulmonary angioplasty (PTPA) or balloon pulmonary angioplasty, has been developed as a promising strategy for CTEPH. Therefore, the usefulness of PTPA for residual or recurrent pulmonary hypertension after PEA was investigated. ⋯ A hybrid approach combining PEA and additional PTPA may be reasonable for patients with both proximal and very distal lesions not easily approachable by PEA. PTPA could be a promising alternative therapeutic strategy for residual or recurrent pulmonary hypertension after PEA.

Review Meta Analysis
Network meta-analysis for evidence synthesis: what is it and why is it posed to dominate cardiovascular decision making?
Clinical decision-making requires synthesis of an often complex evidence base. Novel tools have been developed building upon the historical approach of reviewing the literature focusing on a specific topic. Stemming from qualitative reviews, systematic reviews of randomized clinical trials, typically encompassing statistical pooling with pairwise meta-analysis, have been devised and are now considered one of the uppermost ladders in the hierarchy of clinical evidence. ⋯ These methods include adjusted indirect comparison meta-analysis, network meta-analysis, and mixed treatment comparison. While still the focus of intense research and debate, they represent a powerful tool for evidence synthesis and comparative effectiveness in cardiovascular research, and thus are likely to become increasingly popular and impactful in shaping research agenda and clinical practice. This is clearly highlighted by a number of recent landmark network meta-analyses on smoking cessation therapies, coronary stents, and management of patent foramen ovale in patients with history of cryptogenic stroke.
