AIMS: To assess different aspects of the definition of valvular/non-valvular atrial fibrillation (AF) used in clinical practice by physicians who usually treat this condition.METHODS AND RESULTS: We prospectively conducted a web-based survey including cardiologists and internists who attended continuing medical education courses on cardiovascular medicine. A questionnaire was drawn up, containing 17 questions clustered into five main topics: (A) known rheumatic aetiology; (B) site/type of valve involvement; (C) prosthetic heart valve; (D) haemodynamic relevance; (E) miscellaneous. The overall response rate was 22.4% (21.1% for cardiologists and 24% for internists). Coexistence of both medical history of rheumatic disease and clinical signs of valvular involvement were considered as essential prerequisites for the diagnosis of rheumatic AF by half of the respondents, and one-third assumed that lone aortic valve disease was sufficient for AF to be defined as valvular. A similar proportion of respondents considered that in the presence of mitral regurgitation, AF had to be defined as valvular. The majority of responding physicians considered the degree of valvular defect of lesser importance for the definition of valvular or non-valvular origin of AF.CONCLUSION: We found important heterogeneity and uncertainties in the answers given by physicians who usually treat patients with AF, as evidence of the lack of precise and unique definitions of the origin of AF (valvular/non-valvular). It is urgent to issue clear widely accepted definitions of the origin of AF, which should improve clinical practice and research.
