Characteristics of the patients: clinical features and molecular diagnosis

CaseAge/sexDuke classification*Particular features†Affected valveIndication for surgery‡PCRIdentity§
*From reference 10.
†PVE, prosthetic valve endocarditis; early PVE, < 2 months after surgery; late PVE, > 2 months after surgery. Definitions from reference 1.
‡Indication (class). Class I: there is evidence or general agreement that surgery is useful and effective. Class II: there is conflicting evidence and/or divergence of opinion about the usefulness/efficacy of surgery; IIa, the weight of evidence/opinion is in favour of usefulness/efficacy; IIb, usefulness/efficacy is less well established by evidence/opinion. Class III: there is evidence or general agreement that surgery is not useful and in some cases may be harmful. From reference 17.
§Non-defined: identity of the pathogen not stated; (–): not performed.
