Model 1: univariate analysis; Model 2: urgency adjusted in endocarditis subgroups, active endocarditis adjusted in urgency subgroups; Model 3: logistic EuroSCORE adjusted only
MVr mitral valve repair, MVR mitral valve replacement, IE infective endocarditis
P-interaction for endocarditis = 0.859
P-interaction for urgency = 0.122
