Role of echocardiogram in decision making for surgery in endocarditis

Infective endocarditis is a serious disease that carries significant morbidity and mortality. Adequate treatment is based on a high degree of clinical suspicion, accurate microbiologic diagnosis, and high-quality imaging. Echocardiography has been shown to be a fundamental tool for diagnosis and management. Currently accepted Duke criteria include blood cultures and echocardiography. Transthoracic and transesophageal echocardiography play a critical role in the decision-making process, especially when surgical treatment is contemplated. Because infective endocarditis is considered a medical and surgical disease, and considering that the current rate of surgery is about 50%, echocardiography has definite value in preoperative diagnosis and surgical planning, intraoperative confirmation of lesions and quality of repair or replacement before and after cardiopulmonary bypass, and postoperative assessment.
