“…4 These studies relied exclusively on the M-mode technique, which is inferior for spatial orientation and permits a less comprehensive evaluation of cardiac structure and function, compared with two-dimensional echocardiography. Reports of the use of two- dimensional echocardiography alone and in combination with M-mode recordings suggest that diagnostic abnormalities may be identified in 80% or more of cases.…”

SUMMARY We reviewed M-mode and two-dimensional echocardiographic findings in 11 patients with abacteremic endocarditis to study the application of echocardiography in this setting. All patients had negative blood cultures but underwent surgery that confirmed the presence of active infective endocarditis. The infection involved native valves in five patients and prosthetic valves in six patients. Valvular masses were identified in eight patients. The other three patients, who had prosthetic aortic valves, had diastolic mitral valve vibration characteristic of aortic regurgitation. One of these three also showed dehiscence of the prosthesis.Three patients had poorly defined clinical illnesses and echocardiography was a prime element in the diagnosis because valvular masses were identified. The operation was facilitated by knowledge of the mass indicated by echocardiography in these eight cases. Also, the surgical approach was affected by knowledge of dehiscence and perivalvular abscess formation in two cases each.

“…En EI por Pseudomona aeuriginosa, Enterobacteriaceas y hongos, esta mortalidad puede superar el 50% de los casos durante el período intrahospitalario. En una reciente comunicación del grupo del Estudio Colaborativo Internacional de EI (ICE-PCS), la mortalidad durante el episodio agudo fue de 17,7% 5 , a pesar de los avances crecientes en infectología, los altos estándares en aplicación para la técnica de los hemocultivos (automatización), los nuevos y poderosos antibióticos que se emplean en la actualidad en esta enfermedad [6][7][8][9][10] , de la incorporación de nuevas técnicas diagnósticas imagenológicas, entre las que se destaca, especialmente la ecocardiografía [11][12][13][14][15][16][17][18][19] ; los nuevos y estrictos criterios diagnósticos que se han incorporado [20][21][22] y el perfeccionamiento de las técnicas cardioquirúrgicas, incluidos rigurosos controles pre e intraoperatorios, así como de los dispositivos intracardiacos en uso [23][24][25][26][27] , todos ellos factores que se suman para reducir la morbimortalidad de esta patología en las últimas décadas [28][29][30] , esta mortalidad continúa elevada.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Because changes in gain settings may produce striking changes in the intensity of VEG and because the above observations were subjective, no firm conclusions could be drawn from these studies.7,14-17 The 22 patients presented in this study constitute a consecutive series of patients with a clinical diagnosis of IE on native valves; they were selected by strict criteria and were followed on a prospective basis. All recording variables on the echocardiographic machine were noted at the time of the initial study and were kept identical in follow-up studies.…”

Value of digital image processing of two-dimensional echocardiograms in differentiating active from chronic vegetations of infective endocarditis.

The ability of a computer-based image digitizing system to differentiate "active" from "'chronic" valvular vegetations was evaluated. Twenty-two patients with newly diagnosed infective endocarditis were studied prospectively by serial two-dimensional echocardiograms. Two comparable images (active and chronic) from the same patient taken several weeks apart (range, 4-17 weeks) after initiation of therapy were obtained at end diastole with identical gain settings. The images were digitized, magnified, and displayed on a high-resolution color monitor. The mean pixel intensity of the valvular vegetation in the active stage was 20.6 ± 3.6 (mean ± SD), which increased to 34.4 ± 4.3 in the chronic stage (p<0.01). Because there was some overlap of values, an additional standardization procedure was used in the last eight patients. In these eight patients, the mean pixel intensity of the vegetations in the active stage was 17.5 ± 1.1, and it increased at 4 weeks to 25.0 ± 1.2 (p<0.05) and further increased in the chronic stage to 33.6 ± 3.1 (p<0.05). (Circulation 1988;78:116-123) I nfective endocarditis (IE) most often involves the cardiac valves and can be detected by M-mode and two-dimensional echocardiography: the sensitivity of M-mode and twodimensional echocardiography for the diagnosis of IE has ranged from 34% to 80%.
