Cardiogenic shock due to partial occlusion of the left coronary ostium in infective endocarditis: a case report.

The case is presented of chronic aortic valve endocarditis in a previously asymptomatic 54-year-old male. The main initial clinical manifestation was cardiogenic shock, but further examination revealed the presence of a large mobile mass attached to a bicuspid aortic valve, partially occluding the left coronary ostium. The patient underwent emergency surgery to excise the vegetative mass and preserve the aortic valve. The postoperative outcome was satisfactory.
