The correct answer is
BPerivalvular abscesses are seen in about 30% of patients with bacterial endocarditis. It is important to detect these lesions, because they indicate advanced disease that has a poor prognosis and thus necessitates aggressive medical management and sometimes surgery. Transesophageal echocardiography (TEE) is the method of choice for detecting infective endocarditis of both native and prosthetic cardiac valves. This technique also aids in the detection of complications, such as perivalvular abscesses and pseudoaneurysms, with good sensitivity (80%–87%) and specificity (95%–98%)
