Weights of curetted adenoid were measured and were compared with both weights of tonsils and the rate of adenoidectomy among the tonsillectomized cases. This study included 603 patients whose adenoids were curetted during the 11-year period. 90% of patients were 2 to 9 years old. The rate of curetted adenoid vegetation among the tonsillectomized cases was 80% among patients from 1 to 6 years ol...

Rabbits with established staphylococcal endocarditis, injected twice at an interval of 2 h with either 0.5 mg of cloxacillin per kg or saline, were sacrificed 2.5 h after the second injection. Vegetations were excised, weighed, and cultured, and ultrathin sections were prepared and examined by light microscopy, transmission electron microscopy, and scanning electron microscopy. Several affected...

Recent European guidelines have emphasized the association of vegetation size with embolic risk in endocarditis (1). On these grounds, left-sided vegetations >1 cm, and right-sided vegetations >2 cm are considered to be an indication for surgery. In this issue of iJACC, investigators from the MEDIC (Multicenter Electrophysiologic Device Cohort) registry report the importance of vegetation size ...

Background Transesophageal echocardiography is superior to transthoracic echocardiography in detecting left-sided valvular vegetations. There are no data on the value of transesophageal echocardiography in the diagnosis of infected transvenous permanent pacemakers. Methods and Results Transthoracic and transesophageal echocardiography was performed in 10 patients for whom there was clinical sus...

Nine patients with anatomically documented vegetations on one or more cusps of the aortic valve had echocardiograms in which abnormal echoes were associated with the aortic leaflet echoes. The motion of the abnormal echoes during systole correlated well with the anatomic location of vegetations: a vegetation on the right coronary cusp moved anteriorly with systole while a vegetation on the nonc...

S UBACUTE bacterial endocarditis involves the left side of the heart in nearly all cases. The complete descriptions of the disease by Libman and Friedberg,’ Blumer,2 and Middleton and Burke3 refer chiefly to this common type. The vegetations are confined to the right side of the heart in less than 4 per cent of the cases.4*6 In patent ductus arteriosus complicated by subacute bacterial endarter...
