Infective endocarditis and complications a single center experience

OpenAlex English

OBJECTIVES: The aim was to investigate the microbiological characteristics and complications of infective endocarditis (IE) in 119 patients treated in our center for IE, diagnosed by modified Duke criteria. STUDY DESIGN: The archive records of 119 patients (82 [69%] males; 37 [31%] females; mean age 39 ± 16 years) with a definite diagnosis of IE between January 1997 and November 2004 were systematically reviewed for clinical and microbiological properties and complications. RESULTS: The most common complaint of the patients was fever and malaise (102 patients, 85.7%, each). Culture was negative in 68 patients (57.1%), while Staphylococcus aureus was the most common etiological agent in culture positive cases. The aortic valve was the most common region of vegetation (43 patients, 36.1%). The frequency of surgical operation for valvular insufficiency due to IE was 75.6%, and the frequency of congestive heart failure was 53.8% (64 patients). CONCLUSION: IE is still an important disease considering its high morbidity and mortality rates, increased life expectancy of the patients, and increased number of valve replacement procedures.
