Infectious endocarditis (IE) is caused by a variety of microbial agents and poses severe complications such as embolic and septic events. This condition is aggravated among elderly patients and is associated with a high morbidity rate. Recent advances in diagnostic modalities, especially transesophageal echocardiography (TEE) have revolutionalized early diagnosis, prediction of emboli, treatment and evaluating the outcomes of interventions. In this article, we explain our experience with 4 cases of infectious endocarditis. Having had the clinical suspicions to IE, patient underwentroutine diagnostic procedures including transthoracic echocadiography (TTE) and blood culture. Surprisingly, TTE was negative for all patients however, the clinical symptoms and the presence of complications were favoring IE, therefore, all were subjected for TEE. TEE confirmed the diagnosis of IE in all 4 cases. There were mitral valve vegetations measured 0.5-3cm in three cases, whereas the other one presented with aortic valve vegetation measured 1cm. Three patients had blood culture positive for staphylococcus aureus and one patient with aortic valve vegetations had enterococcus positive blood culture. All patients had developed various complications and one had splinter hemorrhage. Two patients underwent surgical valvuloplasty, however, one of them was re-operated for splenectomy due to splenic abscess. All patients received an appropriate antibiotic regimen including vancomycine and cefteriaxon and were discharged in satisfactory state. Patients were routinely admitted for follow up TEE, while none developed symptoms or complications compatible with IE. Our results revealed that TEE is significantly superior to TTE for diagnosis and follow up of IE.
