Infective endocarditis is least likely to occur in
Aerial septal defect
Small ventricular septal defect
Mitral valve prolapse
Tetrology of hea
Ref Harrison 19 th ed pg 816 Infection most commonly involves hea valves but may also occur on the low-pressure side of a ventricular septal defect, on mural endocardium damaged by aberrant jets of blood or foreign bodies, or on intracardiac devices themselves. The analogous process involving aeriovenous shunts, aerio-aerial shunts (patent ductus aeriosus), or a coarctation of the aoa is called infective endaeritis.
