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.

Randomized Controlled Trial Multicenter Study
Dexamethasone for the prevention of postoperative atrial fibrillation.
Postoperative atrial fibrillation (AF) is a common complication after cardiac surgery. Inflammation is believed to play a pivotal role in the etiology of postoperative AF. There is a suggestion from small studies that perioperative treatment with corticosteroids may reduce postoperative AF. The DExamethasone for Cardiac Surgery (DECS) study was a large randomized trial showing no protective effect of dexamethasone on major adverse events. The aim of this study was to investigate the effect of dexamethasone treatment on the occurrence of AF after cardiac surgery. ⋯ Intraoperative administration of dexamethasone had no protective effect on the occurrence of any or new-onset atrial fibrillation after cardiac surgery. Therefore, the use of dexamethasone for the reduction of postoperative AF should not be recommended.

Multicenter Study Comparative Study
Transfemoral transcatheter aortic valve replacement compared with surgical replacement in patients with severe aortic stenosis and comparable risk: cost-utility and its determinants.
To evaluate cost-effectiveness of transfemoral TAVR vs surgical replacement (SAVR) and its determinants in patients with severe symptomatic aortic stenosis and comparable risk. ⋯ In countries with relatively low health care costs TAVR is not likely to be cost-effective compared to SAVR in patients with intermediate risk for surgery, mainly because of the high cost of the valve compared to the cost of hospitalization. TAVR could be cost-effective in specific subgroups and in countries with higher hospitalization costs.
