Bacterial endocarditis is most commonly seen in:
Valvular disease alters blood flow and produces jet effects that disrupt the endothelial surface, providing a nidus for attachment and infection of microorganisms that enter the bloodstream. Predisposing valvular abnormalities- Rheumatic involvement of any valve Bicuspid aoic valves, calcific or sclerotic aoic valves Hyperophic subaoic stenosis, mitral valve prolapse Congenital disorders- VSD, ASD, TOF, PDA, coarctation of the aoa Regurgitation lesions are more susceptible than stenotic ones. Though PDA is a close answer, since VSD is more common a lesion and pressure gradient between LV and RV is more than pressure gradient between aoa and pulmonary aery, VSD should be answered for the above question
VSD
PDA
ASD
AS
Bacterial infection
