Abstract

Objectives: We aimed to evaluate demographic data, underlying cardiac abnormalities, clinical profile, microbiological features, treatments and complications of infective endocarditis (IE) in a tertiary hospital in Aseer region, Saudi Arabia.

Methods: A retrospective study of all cases with the diagnosis of definite endocarditis according to modified Duke Criteria admitted to ACH between May 2002 and April 2007. Data were reviewed on demographic and clinical data, underlying cardiac disease, microbiological findings, treatments and complications of IE.

Results: The study included 44 patients (28 males and 16 females; mean age 31.1 ± 16 years; range 13-65 years). Infective endocarditis developed on a native valve in 31 (70.5%), a mechanical prosthetic valve in 10 (22.7%), mitral valve prolapse in 2 (4.5%) and ventricular septal defect in 1 (2.3%). Rheumatic heart disease in 31 cases (70.5%) was the most common preexisting valvular abnormality in native valve endocarditis. The mitral valve was the most commonly affected valve 28 (63.6%). Fever occurred in 40 (90.9%) of the cases. Electrocardiography was abnormal in 34 cases (77.3%). Trans-thoracic and/or trans-esophageal echocardiography showed a vegetation in 22 (50%). Staphylococci in 10 cases (22.7%) and Streptococci in 8 cases (18%) were the most common causative agents and cultures were negative in 20 cases (45.5%). Twenty-two patients (50%) underwent surgical treatment. Congestive heart failure occurred in 16 (36.4%) cases, atrial fibrillation in 6 (13.6%) cases, and cerebrovascular accidents in 4 (9%) cases.

Conclusion: Our data reflects the clinical and microbiological profiles of IE in a tertiary hospital in Aseer region, Saudi Arabia.
