Randomized Controlled TrialRemote-controlled magnetic pulmonary vein isolation combined with superior vena cava isolation for paroxysmal atrial fibrillation: a prospective randomized study.
Radiofrequency ablation (RFA) of paroxysmal atrial fibrillation (PAF) has focused on pulmonary vein isolation (PVI). However, despite initial positive results, significant recurrences have occurred, partly because of pulmonary vein (PV) reconnection or non-PV ectopic foci, including the superior vena cava (SVC). ⋯ SVCI combined with PVI did not reduce the risk of subsequent AF recurrence, and was responsible for two phrenic nerve injuries. Accordingly, the benefit-to-risk ratio argues against systematic SVCI.

Multicenter Study Observational StudyManagement of non-traumatic chest pain by the French Emergency Medical System: Insights from the DOLORES registry.
The early recognition of acute coronary syndromes is a priority in health care systems, to reduce revascularization delays. In France, patients are encouraged to call emergency numbers (15, 112), which are routed to a Medical Dispatch Centre where physicians conduct an interview and decide on the appropriate response. However, the effectiveness of this system has not yet been assessed. ⋯ Emergency physicians in the Medical Dispatch Centre sent an effecter to the majority of patients who called the Emergency Medical System for chest pain. The response level was based on the characteristics of the chest pain and the patient's risk profile.
