M-mode and cross-sectional echocardiograms of 3 cases with vegetative endocarditis in the right-sided heart were reported. The location of vegetative lesions was the tricuspid valve in one, the parietal band of the right ventricle and chordae tendinae in one, and the pulmonary artery wall in the remaining patient. Ruptured chordae tendinae were observed in the patient with tricuspid valve vegetation. M-mode echocardiography detected vegetative lesions in all patients. However, the precise size and location of these lesions, and a complication of the destructive process were not evaluated by M-mode echocardiography. On the other hand, cross-sectional echocardiography not only documented the presence but also assessed the morphologic characteristics of the lesions, since this technique provides spatial orientation concerning moving structures. Furthermore, ruptured chordae tendineae in the patient with tricuspid valve vegetation was correctly estimated. However, the lesions should be differentiated from other conditions including a localized calcified lesion, abscess and thrombus. In conclusion, cross-sectional echocardiography in combination with M-mode echocardiography is recommended in diagnosing vegetative lesions in the right-sided heart.
