Left sided endocarditis is associated with:
In setting of Patent Fossa Ovalis paradoxical embolism ensues and can cause left sided endocarditis. Other septic complications seen with infective endocarditis The infection can also extend into the myocardium, resulting in abscesses leading to conduction disturbances, and involving the wall of the aoa, creating sinus of Valsalva aneurysms. Peripheral embolization to the brain and myocardium may result in infarctions. Embolization to the spleen and kidneys is also common. Peripheral emboli may initiate metastatic infections or may become established in vessel walls, leading to mycotic aneurysms. Right-sided endocarditis, which usually involves the tricuspid valve, causes septic pulmonary emboli, occasionally with infarction and lung abscesses.
