VEGA, Julián et al. Added value of three-dimensional echocardiography in the diagnosis and management of infective endocarditis. Clinical experience. Rev Chil Cardiol [online]. 2017, vol.36, n.3, pp.232-238. ISSN 0718-8560.

The echocardiographic diagnosis of infective endocarditis has evolved in a vertiginous manner. Among its main hallmarks are; the development of transesophageal echocardiography (TEE), harmonics imaging and three-dimensional echocardiography (3D Echo), thereby enhancing its diagnosis capability. The following endocarditis cases revealed the usefulness of 3D Echo. CASE 1. 18 year-old male, past history of septic arthritis, refers decline in functional capacity associated with a mitral regurgitation murmur. Transthoracic echocardiography (TTE) pictured a mildly dilated left ventricle and severe mitral regurgitation. 3D Echo identified a circular perforation of the anterior mitral leaflet; successful mitral valve repair was accomplished. CASE 2. 29 year-old male, with recent dental abscess, presents in septic shock. TTE and TEE portrayed a bicuspid aortic valve (BAV) with severe regurgitation along with an abscess of the anterior mitral valve leaflet. 3D Echo showed a perforation of the nonfused aortic leaflet; double valve replacement was uneventfully performed. CASE 3. 61 year-old male, with remote history of endocarditis and BAV, evaluated with TTE and TEE due to sepsis, depicting moderate aortic regurgitation and P3 prolapse with rupture chordae and severe mitral regurgitation. Based on the 3D Echo data the mitral valve was repaired and the aortic valve replaced. CASE 4. 78 year-old woman with prosthetic mitral valve endocarditis, 3D Echo allowed complete visualization of a 16 mm diameter posterior abscess, being referred to surgery. Thus, 3D Echo has added value in several endocarditis scenarios such as; leaflet perforations, periannular involvement, prosthetic valve endocarditis, improving its management.
