Cardiopulmonary manifestations of isolated pulmonary valve infective endocarditis demonstrated with cardiac CT
Right-sided infective endocarditis involving the pulmonary valve is rare. This pictorial essay discusses the use and findings of cardiac CT combined with delayed chest CT and noncontrast chest CT of pulmonary valve endocarditis. Cardiac CT is able to show the full spectrum of right-sided endocarditis cardiopulmonary features including manifestations that cannot be demonstrated by echocardiography.Expanding pseudoaneurysm compressing the coronary arteries and causing cardiogenic shock
A 37-year-old man who recently underwent aortic valve replacement after endocarditis presented with cardiogenic shock. A large expansile pseudoaneurysm was subsequently discovered using multiple imaging modalities. Although transesophageal echocardiography is important in diagnosing valve endocarditis, coronary CT angiography of prosthetic valves is feasible and image quality is good. In this case, coronary CT angiography allowed for better understanding of transesophageal echocardiography images and earlier diagnosis of coronary involvement as cause for left ventricular dysfunction.Imaging of infective endocarditis with cardiac CT angiography
Infective endocarditis (IE) is a disease characterized by high rates of morbidity and mortality that can present with a spectrum of clinical and imaging findings. Cardiac-gated computed tomographic angiography (CTA) has been shown to be highly accurate in evaluation of both coronary artery disease and structural heart disease and is now considered an appropriate preoperative imaging modality in patients undergoing noncoronary cardiac surgery. This review discusses the use of cardiac-gated CTA in preoperative evaluation of patients with IE, with emphasis on imaging findings of valvular and perivalvular complications.
