Infective endocarditis (IE) is a life threatening infection, especially if diagnosis and subsequent treatment are delayed. The aim of this retrospective study was to assess the clinical features and management of infective endocarditis in Malta. Patients admitted to Mater Dei Hospital (MDH) between January 2008 and December 2015 with a diagnosis of IE according to the modified Duke's criteria were selected from electronic case summaries. Demographic data and details on clinical features, risk factors, investigations, management and complications were obtained through the patients’ clinical notes and online laboratory results. There were 65 patients with a diagnosis of IE with a 12.3% (8) mortality rate. Our cohort included 57 patients as the eight deceased patients were not audited due to unavailable case notes. Native valve endocarditis was seen in 80.7% (46) of patients whilst 19.3% (11) had prosthetic valve endocarditis. Left sided vegetations were the most common at 68.4% (39). The majority of patients were culture positive at 87.7% (50). Staphylococci were the commonest organisms cultured at 36.8% (21) of which 57.1% (12) were Staphylococcus aureus with 19.0% (4) being Methicillin resistant staphylococcal aureus. Complication rates were highest in the native valve cohort at 67.4% (31) versus 36.4% (4) patients in the prosthetic valve endocarditis group. IE is not uncommon and can result in severe complications can arise with long-term sequelae. Preventive efforts should be of utmost importance both in the community and in hospitals.
