Background: Patients undergoing aortic valve replacement (AVR) are considered at subsequent risk of infective endocarditis (IE), yet data on incidence of IE and associated factors are sparse.
Methods: Using nationwide registries in Denmark, all patients with no prior or current history of IE who underwent AVR Jan 1996-Dec 2012 were included. Patients were followed from hospital discharge after AVR to either death, end of study period (31th December 2012), or admission to hospital due to IE, whichever came first. Incidence of IE was described by 1, 5, and 10 years after AVR and factors associated with IE were analyzed using multivariable adjusted Cox proportional hazard analysis. Results: A total of 13,454 patients underwent AVR; 36.2% were women and the median age was 71.4 years, IQR: 63.4-77.2 years. Multivariable adjusted analyses identified factors associated with subsequent IE (see Figure). At 1, 5, and 10 years follow up after AVR we found that 1.5%, 3.3%, and 4.7% were rehospitalized due to IE. We found that male gender, bioprosthetic aortic valve, pacemaker at AVR surgery, and diabetes with complications were among factors associated with an increased risk of IE (see Figure). Conclusions: IE was not uncommon in patients undergoing AVR. Male gender, bioprosthetic valve, pacemaker, and diabetes with complications were among factors associated with subsequent risk of infective endocarditis.
