Article Synopsis
- The peQasus study evaluates the safety and effectiveness of a new temperature-controlled high-power short-duration (HPSD) radiofrequency catheter (QDOT Micro) for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF).
- Conducted across 15 centers in Europe, the study involved 1,023 patients and compared outcomes between a very HPSD technique and a hybrid approach.
- Results indicated complete PVI success, a mean procedure time of about 98 minutes, and a similar safety profile for both techniques, with 12-month arrhythmia-free survival rates around 77%.
Article Synopsis
- The oxidative potential (OP) of particulate matter (PM) significantly impacts health, yet the sources of PM-OP in India are not well understood.
- Research conducted at five sites in the Indo-Gangetic Plain identifies major PM sources and their geographical origins, revealing that high PM levels are widespread but driven by local emissions, particularly in Delhi.
- The study highlights that the main PM sources in Delhi are from traffic exhaust and residential heating, while outside Delhi, biomass burning plays a crucial role, suggesting that improving combustion processes can reduce health risks from PM exposure in northern India.
Carbonaceous aerosols (CA) from anthropogenic emissions have been significantly reduced in urban China in recent years. However, the relative contributions of fossil and nonfossil sources to CA in rural and background regions of China remain unclear. In this study, the sources of different carbonaceous fractions in fine aerosols (PM) from five background sites of the China Meteorological Administration Atmosphere Watch Network during the winter of 2019 and 2020 were quantified using radiocarbon (C) and organic markers.

Int J Cardiovasc Imaging

The concept of disproportionate mitral regurgitation (dispropMR) has been introduced to identify patients with functional mitral regurgitation (MR) who benefit from percutaneous treatment. We aimed to examine echocardiographic characteristics behind this entity. We retrospectively included 172 consecutive patients with reduced left ventricular ejection fraction (LVEF), and more than mild MR referred to clinically indicated echocardiography.

In order to achieve a successful ablation, the correct identification of the underlying arrhythmogenic substrate is mandatory to tailor the pre-procedural planning of an ablative procedure as appropriately as possible. We propose that several of the imaging modalities currently used could be merged, including echocardiography (also intracardiac), cardiac magnetic resonance, cardiac computed tomography, nuclear techniques, and electroanatomic mapping.
